Pop Goes the Diet—The Worst Food in the World

Soda
Since all great things come in threes (or is it celebrity deaths?), we’re going to complete our sugar trilogy with a look at the worst food in the world: soda pop. Forget about brands; whether it’s Coke, Dr. Pepper, or even Hansen’s Natural, it’s all junk. There are different degrees of “junkiness,” but this is Nutrition 911, so we’re sticking with the bird’s-eye perspective. The taste might make you happy, but from a nutritional point of view, soda’s only place in the world is to make people fat, sick, and unhappy.

Alarming statistics
In America, we drink a lot of cola (or “un-cola”). A lot. On average, we each drank 52.4 gallons in 2005, and this figure includes infants, healthy folks, prisoners, etc., meaning that the average soda drinker actually gulps (their word) more than this. Carbonated soft drinks are the biggest single caloric source in the American diet. Teenagers in particular are hooked on the stuff and get an average of 13 percent of their daily calories from “pop.” If this doesn’t scare you, it should. In terms of sheer amount, these statistics could be alarming if it were any one food. A proper diet should have some balance and diversity. And soda pop is the antithesis of “any food.” It’s bad food.

“Empty calories”
We use the term “empty calories” for foods like soda that have no place in a nutritious diet. This term is ridiculously misleading. The calories in soda are far from empty. Most of them come from sugar. In the U.S., it’s nearly always high fructose corn syrup, the cheapest, most processed sugar on the market. Other ingredients include caffeine, various phosphates and acids, and artificial colorings. We’ll get to their effects on the human body in a minute, but first, let’s stick to the simple stuff. Per day, the average teenager consumes between 10 and 15 teaspoons of refined sugar via soda—which, according to government standards, is about their daily requirement for all foods. This means that for the average teenager, his or her soda consumption virtually eliminates his or her chances of eating a balanced diet. There’s nothing empty about that.

Weird science
The soda companies are a marketing juggernaut. They spend roughly $700 million a year on media advertising alone—not to mention hundreds of millions more sponsoring events, athletes, musicians, and such. This volume of cash makes it difficult for consumers to avoid them, by design. To avoid the temptation to drink Coke, you’ve got to be highly principled or living in the middle of the jungle. And even then, well, I once happened upon a soda vending machine halfway up Mount Yarigatake in the Japanese Alps, and a friend traveling in Guatemala found Coke in a rural area that didn’t have running water. Let’s just say that soda companies are going to continue making it easy for you to find the stuff. This type of marketing machine won’t go away quietly. With the stats listed above, you could certainly put two and two together and link soda companies to the childhood (and adult) obesity epidemic that is arguably the world’s most serious health crisis. Yet, while researching this article, I came across a widely published “study” stating that “soft drink consumption has no effect on childhood obesity.” Suspicious from the get-go (the word “no” being a huge red flag), it didn’t take me long to find this statement: “The research paper was supported by an unrestricted gift from the American Beverage Association.” Bingo. Remember those Philip Morris tobacco “studies” that promised a long and healthy life from chain smoking?

What makes it so bad?
Besides the simple caloric trade-off, sodas are formulated to give you a rush. The sugar is mixed with phosphates designed to speed it into your system. It’s so good, in fact, that many cyclists prefer Coca-Cola to specific sports food when they need a sugar rush near the end of races. And while a sugar rush is a good thing when you’re trying to exceed your anaerobic threshold and you’re out of blood glycogen (never mind if you don’t know what this is), it’s a bad thing whenever you’re not, which even for a competitive cyclist is 99.9 percent of the time.

Beyond the simple sugar rush, these acids and phosphates alter your body’s pH levels and inhibit the absorption of other nutrients. Then there are the effects of certain artificial coloring agents. For example, yellow #5, commonly used in soft drinks, has been linked to attention deficit disorder, hives, asthma, and other allergic reactions in some children.

Then there is the nutrient trade-off to consider. A person who drinks one Big Gulp per day must go to great lengths to maintain a balanced diet. Otherwise, he or she will almost certainly be deficient in numerous vitamins, minerals, dietary fiber, and essential fatty or amino acids—none of which is found in soda. For this reason, soda is often linked to type 2 diabetes, osteoporosis, dental erosion, and a higher risk of kidney stones and heart disease. And that’s just a start. There’s plenty of less scientific data linking soda to poor scholastic habits, which we’ll get to in a later class.

Diet sodas and juices
In an attempt to become thought of as healthier, soda companies have diversified into non-carbonated beverages and diet sodas. While these are an improvement in some ways, they are hardly a solution to the problem. First off, most juices and other caloric non-soda alternatives are mainly just sugar and water without the carbonation. A quick label comparison between a commercial orange juice and a Mountain Dew would show a similar “bottom line” with regards to calories and sugar. The only improvement would be the lack of the non-caloric offenders. But that’s no small matter, as the true effects of these ingredients have not been thoroughly studied. Despite their no-calorie status, diet sodas have been linked to assorted illnesses. Recent studies have backed up my more anecdotal evidence that I’ve yet to have a client not lose weight by kicking diet soda. Granted, all of my clients drank an excessive amount, but regardless, there is little doubt that the pH balance of diet sodas hinders the body’s ability to absorb nutrients, and that just may be the tip of the non-caloric iceberg.

A large-scale study in 2007 showed that men and women who had more than one diet soda a day were 31 percent more likely to be obese and 25 percent more likely to have both high triglycerides and blood sugar, and they had a 50 percent greater risk of developing metabolic syndrome. Never mind if you don’t know what metabolic syndrome is. Just trust me when I tell you that you don’t want it.

How can you help?
In my world, soft drinks would come with the same type of regulatory language as cigarettes and booze, at least. Actually, in my world, we’d all be educated and wouldn’t require this language at all, but that’s Politics 911, not Nutrition 911. Anyway, here are five ways you can help educate the public about the dangers of soda, according to the Center for Science in the Public Interest. Contact your local government officials and/or the Food and Drug Administration (FDA) and suggest that:
1. National and local governments should require chain restaurants to declare the calorie content of soft drinks and all other items on menus and menu boards.
2. The FDA should require labels on non-diet soft drinks to state that frequent consumption of those drinks promotes obesity, diabetes, tooth decay, osteoporosis, and other health problems.
3. Local, state, and federal governments should provide water fountains in schools, government buildings, parks, and other public spaces.
4. School systems and other organizations catering to children should stop selling soft drinks (as well as candy and other junk foods) in hallways, shops, and cafeterias.
5. State and local governments should consider levying small taxes on soft drinks, with the revenues earmarked for promoting health and fitness. A national 2-cent tax on a can of soda pop would raise $3 billion annually.

Are you scared yet? You should be. Or you could just stop drinking soda. Sounds so simple, doesn’t it?

What and When You Should Eat

Clock
It’s not just what you eat but when you eat that matters. The perfect food for one situation may be horrible for another. Nutrient timing is a science that athletes use to try to get the most out of every calorie they consume. Not everyone needs an athlete’s level of efficiency, but all of us will benefit from a basic understanding of nutrient timing.

This is 911, need-to-know info only. To keep you focused on the big picture, I’ll begin with an example at the extreme end of nutrient timing. If the average Joe followed the same diet as an Ironman triathlete, he’d likely have type 2 diabetes in a matter of months. Conversely, if someone tried to complete an Ironman on even the healthiest version of a low-carb diet, that person would either be forced to quit or die. This is not just because either diet would mean eating too much food or too little food. Different foods cause the body’s metabolic process to react in different ways; and various activities should be fueled using various means.

Let’s begin by looking at our possible fuel sources:
Carbohydrates
Are fuel only. They aren’t stored in body tissue, only in the blood and liver as glycogen, which needs to be burnt off. They are essential for high-level functioning like running fast, lifting heavy things, and thinking. They are digested and put to use by your body very quickly. If you eat more than you burn, your body will convert them to be stored in adipose (fat) tissue.

Proteins
Called the body’s building blocks. Hence, you need them to rebuild tissue that breaks down daily. You digest proteins slowly, and at a certain point, your body just can’t assimilate them. Therefore, it’s important that throughout the day you eat foods that are high in protein.

Fats
Help regulate all of your bodily functions. They are dense and contain over twice the calories of proteins and carbohydrates. While they are vital for our health, it’s easy to eat too much of them, which will result in unwanted fat tissue on your body. You digest fats slowly, and fats will also help slow the digestion of anything else you eat. Fats are also your backup fuel source, though they can’t be put to use right away the way carbs can.

Fiber
Categorized as a carbohydrate, it is not a source of fuel as it has no calories. It’s the indigestible part of a plant and is of vital importance in your diet because it regulates the absorption of the foods you eat. It also helps us feel full. Most of us don’t eat enough fiber, and that’s a big part of the obesity problem.

Alcohol
Not really a food source but something we tend to consume. It has nearly twice the calories of proteins and carbs (though it lacks fuel) and digests rapidly. Its only healthy function is that it seems to make us happy. Studies indicate this is a good thing, as those who consume alcohol generally live longer than those who don’t, but from a purely nutritional standpoint, it’s not so hot because you’re getting calories without any upside. Its use should be strategic and regulated for best results.

Now let’s look at the various situations we face daily, at least on most days—hopefully.

Relaxing
This is when we’re sedentary both physically and mentally. In a relaxed state, you burn very few calories because your body is engaged as little as possible, hence the relaxing.

Sedentary work
When we’re at work or school. Our bodies aren’t moving, but our brains are engaged. The brain runs on glycogen, which is blood sugar fueled by carbohydrates.

Low-level exercise
Like mowing the lawn, cleaning the house, or going for a walk. This breaks down body tissue, so you’re burning calories, but it’s not intense work. Therefore, it can be fueled by your stored body fat. Your body tries to fuel its low-level outputs by mobilizing fat stores because this saves its limited glycogen for emergency situations.

High-level exercise
Fueled by glycogen. When you really have to get after it, all sorts of hormones go to work, and your body burns its blood sugar. Body-tissue breakdown is rapid, and your stored blood sugar (glycogen) won’t last much more than an hour.

Sleep
A very active time. Deep sleep is where your body works the hardest to repair itself. You need nutrients to make these repairs, but it’s better if you aren’t mucking up the process with digestion. This is why you hear that you shouldn’t eat too much at night. It’s best to eat early to allow most of the digestion to happen while you’re awake, thus allowing your body to use all its energy for recovery during sleep. It is worth noting here that it’s better to eat before bed if you need the nutrients—don’t skip them. Your body can’t repair itself without nutrients, and recovery from breakdown is why we eat in the first place. Next, let’s take a look at an important word you need to know: insulin.

Insulin
Wikipedia tells us that insulin “is a hormone that has extensive effects on metabolism and other body functions, such as vascular compliance. Insulin causes cells in the liver, muscle, and fat tissue to take up glucose from the blood, storing it as glycogen in the liver and muscle, and stopping use of fat as an energy source.” Okay, that’s a little scientific, but look at all the things we’ve already referenced: hormone, glycogen, metabolism, and fat as an energy source. Even if you don’t fully comprehend “vascular compliance,” you can tell that insulin is something important in today’s discussion.

Sure enough, it’s the only hundred-dollar word we need to know today. Your body’s insulin response is the main reason you want to eat certain foods at certain times, to do certain things.

Putting it all together
Now let’s take what we’ve just learned and put it to use. For most of us, nutrient timing is pretty simple. The next thing to consider is what you’re going to be doing or what you just did. As I said before, what you eat should be based on this. You’ve probably heard about the evils of sugar, or maybe even the glycemic index. Using the science of nutrient timing, you can turn sugar into something healthy because it’s the only thing that transports nutrients into your blood quickly enough to be of service during and after hard exercise.

Essentially, sugar or other easily digested carbs (the less fiber the better) promote an insulin release. This speeds the transformation of carbohydrates into glucose in your blood. As your glycogen stores are depleted during exercise, recharging them with sugar minimizes the damage done by the breakdown of tissue during exercise. Therefore, sugar, the oft-vilified ingredient, is actually your body’s preferred nutrient during times of excessive stress and tissue breakdown.

Pretty cool, huh? The bad news is that this miracle nutrient is not good for you when you’re not doing intense exercise, which for almost all of us is most of the time. In fact, sugar’s very bad for you because the insulin response that was so fabulous for you when you were bonking (glycogen depleted) is not so fabulous for you when you’re sitting in front of the boob tube.

Remember this from the Wikipedia definition of insulin, “stopping use of fat as an energy source”? That’s bad when you’re sitting around. Remember how one of dietary fat’s responsibilities is to fuel you during low-intensity exercise? Well, when sugar causes your insulin to spike, it cuts off that process. Now not only are you not burning body fat for low-level outputs, you’re trying to force your body to use its glycogen. Double bad.

Unless you’re exercising, sugar intake should be minimized. During these times—which is most of the time—your diet should consist of a mixture of proteins, fats, and complex carbohydrates. The latter are natural sources of carbohydrates that generally come with fiber, which regulates the insulin response. Whole fruit, a simple carbohydrate by definition because it contains fructose (a sugar), always contains fiber and, thus, can be treated as a complex carb. Fruit juice, and other such stuff, is processed; it, along with processed complex carbohydrates like white rice, can cause an insulin response, so these types of foods should be used more like sports foods than staples.

It’s also important to note that combining all these different nutrients slows sugar’s ability to incite insulin into action. Therefore, a little sugar like a dessert after a well-rounded meal is buffered by the meal. The calories and lack of decent nutrients (processed sugar is devoid of most nutrients, except for energy) still count toward your overall diet, but at least you don’t have to worry about an insulin spike.

So the main point of this article is very simple. You should eat small, well-rounded meals most of the time. These should include some proteins, some fats, some fiber, and some carbs. During (only if it’s a long workout) and after hard workouts, you should supplement your diet with sugar or simple carbohydrates. After this, you should go back to eating well-rounded meals again.

Sports nutrition has evolved this process even further. In nature, foods are generally slow to digest. Nature’s great sports foods are things such as bananas and figs. These are sugary but still contain fiber and other nutrients. Science has found ways to make foods that are even more efficient during sports. These basically manipulate pH levels and process the sugars to speed them into your system. Outstanding when you need it. Terrible when you don’t.

They’ve even taken this a step further by finding a ratio of other nonsugary nutrients (like protein) that can be transported by the sugar to give you a further benefit. Beachbody’s Results and Recovery Formula uses this science. When you’re bonking during a hard workout, it speeds nutrients that are essential for quick recovery into your system as quickly as possible.

I can’t stress how important it is that sports fuels be used for sports performance only. Gatorade, soda, and all sugar candies (hey, no fat!) all function as the poor man’s sports foods. Unfortunately, those perusing the Quick Stop generally aren’t trying to fuel up after doing Plyo X, and therein may lay our obesity trend.

In case the topic is still a bit fuzzy, let’s use the above logic on the examples in the intro: An Ironman athlete is doing intense exercise for 10 to 12 hours or more. During this time, that athlete is mainly burning glycogen, which is gone after an hour or so. The athlete burns stored fat, too, but this is limited in its effectiveness. To race, the athlete must replenish with sports foods because they contain the only nutrients that the athlete will digest fast enough to help. To complete an Ironman, especially at your physical limit, it may take 5,000 calories coming mainly from sugar.

This is a sports-specific diet only. Someone trying to eat that way during a viewing of the Lord of the Rings trilogy would be lucky to stay out of the emergency room. Conversely, if you tried to maintain a 25-mph speed for 8 hours on your bike while munching on raw spinach and lean steak, you’d bonk so hard you’d be praying to get yanked from the race at the first checkpoint. That should cover your 911 on nutrient timing. Next time, we’ll move on to the topic of supplements. Are they magic pills, overhyped placebos, or something in between?

Coffee, Tea, and Caffeine

Coffee, Tea & Caffeine
Today we discuss the most popular drink in the world: coffee. I don’t actually know where these statistics come from, but since we mainly want to discuss one ingredient, caffeine, I’ll lump coffee, tea, and other caffeinated beverages into the same discussion so that we’ll be sure to address something that’s pertinent to almost all of you. Coffee and tea have been around for the entirety of recorded history, so no matter what science tells us, we begin this edition with some time-tested knowledge that people don’t go around dropping dead over the stuff, nor will it get you banned for cheating when you win at the Olympics (unless it’s too much).

Coffee and tea are probably the most controversial substances we consume. Unlike, say, soda, candy, chocolate, and fast food—which we know are detrimental to our diets—studies swing both ways over the benefits and dangers of our morning cup of java. But whatever the outcome, we drink the stuff with an almost ritualistic glee. If you drink neither coffee nor tea, you’re an outsider in almost any culture on the planet.

Coffee, tea, and other caffeinated drinks
First off, let’s talk about the difference between tea, coffee, and other drinks laced with caffeine. Coffee and tea are both very simple products made from mixing ground-up plants with hot water. So they’re both 100 percent natural, contain approximately zero calories, and have a few nutrients. What they do contain is caffeine. A lot of it. Coffee has nearly twice as much caffeine as tea, but the amount varies by type and the brewing process. As a general rule, trendy green teas have less caffeine than black teas, which have less than coffee. Figure that for each cup of coffee or tea you consume, you’ll get between 50 milligrams and 200 milligrams of caffeine.

Both have other assorted nutrients, mainly antioxidants, all of which are quite healthy. The downside is that both are acidic to the point that habitual consumption can cause stomach problems in some people. But the main hit or miss with folks when it comes to coffee or tea is the caffeine. After this, their choices are usually made by taste, ritual, or the culture they live in. Caffeine gives you a jolt of energy, which we’ll discuss later, and because of this, many other beverages now come with a healthy dose of the stuff. Most sodas have some caffeine, but the big trend today is toward turbocharged “energy drinks,” a topic for another day. These are often nasty concoctions of sugar, caffeine, and other assorted legal uppers designed to amp you sky-high and provide the illusion that you’re having a good time. They may work, at least for a short time, but they are basically just time bombs of euphoria. When you crash, you crash hard.

Can coffee or tea make you fat?
There is one place we have a definitive answer on this subject, and it’s that neither of these drinks will make you fat. In fact, they should do the opposite. Caffeine is a diuretic, meaning that it affects your metabolic process at a heightened level. Translation: it makes you go to the bathroom more often. It also elevates brain activity, which, technically, should make you less hungry. This is why caffeine is often added to diet aids.

The only things in coffee or tea that can make you fat are the things you add to them. The menu at your local Starbucks contains stuff that makes coffee merely a side dish, if that. And traditional drinks such as Thai iced tea are only tea in name. Therefore, just because something calls itself “coffee” or “tea” doesn’t mean that’s all there is to the story. Like with most foods, reading labels is important. We’ll talk more about coffee drinks next time.

The latest research
Coffee has been in the headlines a lot recently. You may have caught the headlines a while back stating that it could give you a heart attack. Or maybe you caught the study touting it as a superfood, which came out at the same time! Certainly, you’ve heard that it’s a banned substance by the International Olympic Committee (IOC) due to its performance-enhancing qualities. But then why, you wonder, did you just see a headline saying you should avoid it prior to a workout? And what about that study stating that if you drank enough coffee, it would stave off the effects of all that alcohol you consume?

Coffee, tea, and caffeine are perhaps the most widely studied things we put into our bodies (over 19,000 recent recorded studies), yet no definitive stance can be found on the stuff. If this seems odd, we must consider the fact that studies need to be funded and a lot of money can skew a study to say this or that—a subject I touch on often in my blog. At any rate, let’s wade into some of the more recent headlines and try to make some sense out of them.

Will coffee give you a heart attack?
Apparently it will—if you’re “at risk for heart attacks,” according to a syndicated article that was all over the Internet a while back. But what does this mean? The article begins with the vague line about how coffee may trigger a heart attack in some people. If you delve deeper, the water becomes muddier, so, tired of sifting through their muck, I went to the source.

For over 4 years, a large Costa Rican study examined the relationship among 503 nonfatal heart attacks. The study found that most of the subjects drank coffee prior to having the heart attack. In the stats, it appeared that light coffee drinkers were at more risk than heavy coffee drinkers. This, as you might suppose, caused some confusion. Looking deeper into the abstract, we see that the researchers think that the coffee/heart attack relationship stems from a rare gene variation in some people. They also stated that their research was “far from conclusive.” The report on Yahoo!® made no mention of the gene variant and, instead, went with the more alarmist “those at risk” line because “who isn’t, right?” The study also clearly stated that most of the population was at zero risk from drinking coffee.

The bottom line of the study was that most of the population was not at risk, and the few that might be, also may not be. So, for now, I’ll side with Dr. Robert Eckel, former president of the American Heart Association, and remain “unconvinced.” Furthermore, a study done over 2 decades using 120,000 subjects concluded that there was no relationship between even heavy coffee drinking and heart disease. This study, done in part by the Harvard School of Public Health, showed that there was no link between heart disease and a daily intake of six or more cups of coffee per day. It also stated the risk was the same for those who consumed less than one cup of coffee or tea per month. This study also addressed the Costa Rican findings, stating they were “possible” but “require confirmation.”

Can you lose your gold medal?
Not anymore. In 2004, the IOC removed caffeine from its list of banned items. Prior to that, athletes could be busted for drinking about five or more cups of coffee. Certainly, this means that some highly regarded scientists once thought it was an ergogenic (a performance enhancer). But was it removed because it was found to be ineffective, as there are now better ways of “cheating,” or because the coffee lobby contributed to the IOC? Time may or may not tell, but one thing’s for sure: many people believe caffeine enhances performance.

A recent Swiss study, however, refutes it, at least in one sense. The study of 18 individuals showed that coffee prior to exercise restricted heart blood flow by 22 percent. Obviously, this would be a detriment to performance, but again, the research is far from conclusive. For one, the study used regular coffee drinkers, and participants were not allowed to drink coffee for 36 hours prior to the experiment, so their results may have had to do with a coffee-withdrawal effect. And two, no study of 18 people can be anywhere close to conclusive. But it’s interesting, for sure, and certainly much more will be done. I’d keep an eye out for more on this.

But again, there’s a lot more science showing that it has positive physical effects, even if they stem from better brain function. An Austrian study using functional Magnetic Resonance Imaging to assess memory skills showed that there was a marked improvement in motor skills and memory after subjects ingested 100 milligrams of caffeine. The study cautioned that the progression was not linear (meaning that more is definitely not better). But the test concluded that caffeine was a a performance enhancer.

According to physiologist Terry Graham, PhD, of the University of Guelph in Canada, “What caffeine likely does is stimulate the brain and nervous system to do things differently. That may include signaling you to ignore fatigue or recruit extra units of muscle for intense athletic performance.” And as to whether this better aids strength or endurance sports he adds, “What’s amazing about it is that unlike some performance-enhancing manipulation athletes do that are specific for strength or endurance, studies show that caffeine positively enhances all of these things.”

Is coffee a superfood?
This would depend, I guess. We’ve seen some downsides, and I’ve yet to mention two others. One, it’s addictive, and two, it’s been linked to insomnia. Performance-wise, sleep is crucial for your body to recover and recharge itself. No matter its benefits, if coffee negatively affects your ability to rest, it’s not going to help you much.

Yet, analyzing data—of 126,000 people and gathered over 18 years—has led to an almost astonishing number of likely health benefits, including lowering your risk of diabetes, Parkinson’s disease, and colon cancer; improving mood; appeasing headaches; and even lessening the risk of cavities. In some cases, even the “all things in moderation” cliché was put to the test. For example, drinking one cup to three cups a day reduced type 2 diabetes risk by single digits, whereas drinking six or more cups per day slashed men’s risk by 54 percent and women’s risk by 30 percent. Maybe it’s just because coffee makes you want to get up and do something; those participants who reduced their risk may have exercised more. These findings have been routinely backed up by further studies. At least six studies indicate that coffee drinkers are up to 80 percent less likely to develop Parkinson’s disease, with three showing the more they drank, the lower the risk. Other research shows that compared to not drinking coffee, at least two cups daily can cut your risk of gallstones in half, provide a 25 percent reduced chance of contracting colon cancer, and offer a whopping 80 percent decline in liver cirrhosis risk. So abundant is this research that caffeine is added to certain medications to treat headaches, mood, asthma, and now Parkinson’s disease.

So is it time to hit Starbucks?
Since, as I’ve said before, this isn’t Politics class, I won’t tell you not to, but I’m certain that your local organic, fair-trade, mom-and-pop coffeehouse with the open mic on Thursdays will have better coffee anyway (wink). Back to the subject, coffee or tea certainly don’t seem to be harmful as a part of your diet. The problem with them, I suspect, is more often what we add to them. So if you enjoy your morning or afternoon (maybe skip the evening) ritual, then by all means indulge. Just keep it traditional, pure, simple, and forget the word Frappuccino was ever invented.

Sugar vs. Fat: Which Is Worse?

Sugar
Ladies and gentlemen, tonight we bring you The Thriller in Vanilla, the long-awaited fight to crown the World Obesity Federation’s heavyweight champion. It’s the battle to decide, once and for all, which contender is most responsible for making us fat. In one corner, we have our long-reigning champion, The Heartbreak Hammer, Fat! In the other corner, we have the up-and-coming challenger everyone’s been talking about, The Soda Pop Kid, Sugar!

As the undisputed nutrient kings of our fast food world, this is the bout that everyone’s been waiting for. Fat has been the people’s champion for a long time. Sugar, on the other hand, has only been around as long as humans have been altering foods from natural sources. Lately, a lot of money and science have changed our challenger’s traditional fighting style, leading to a string of TKOs (technical knockouts) en route to its shot at the title. Going into tonight’s fight, however, the experts still favor The Champion by 2-to-1 odds.

The tale of the tape
Sugar—Weighing in at 4 calories per gram, the challenger is slight in stature compared to our champion and will look to speed to gain an advantage. Sugar is a carbohydrate, but the form we consume it in is much different than how we find it in nature, where’s it’s surrounded by a fruit, grain, or other plants. The Soda Pop Kid is synthetic crystalline sugar—the kind that goes into soda, candy, and many convenience foods. Its main weapon is the speed with which it rushes into your system.

Fat—At 9 calories per gram, Fat outweighs its challenger by more than double. Unlike Sugar, Fat is its own food group and an essential part of our diets, just like carbohydrates and protein. It’s easily found in nature in many forms and doesn’t need to be processed. This, of course, doesn’t mean we don’t process it when it’s convenient or cost-effective. As opposed to Sugar, Fat moves into your system slowly. Then it remains there for as long as it can. In abundance, it clogs things up. Its main weapon being bulk, its goal is to wear you down.
As you can see, we’ve got a classic tortoise-vs.-hare matchup between these two heavyweights.

A brief history
Sugar—Since all carbohydrates are broken down into sugars in our blood, it’s always been a part of our diets. However, when eaten as a complex carbohydrate or encased in fiber (as in fruit), it affects our bodies differently than it does as processed sugar. Bees were the first sugar producers, and humans have been eating honey for about as long as bees have been making it. However, it didn’t become a major part of our diets until thousands of years later. Westerners began the production of sugar around 1500 BC. Originally made from sugarcane and sugar beets, it’s now manufactured from other crops, like corn and wheat, which makes up the bulk of the sugar consumed in the U.S.

Modern technology has enabled us to tamper further with natural sugar. Traditional sugar, like honey, had a much lower glycemic index (GI) than many modern variations. Since the higher the GI number, the quicker the sugar rushes into your system, we are now essentially able to have sugars affect the body like a drug, creating exaggerated hormonal responses, particularly the hormone insulin. You may have heard of insulin because, when we have trouble producing it, we have a disease called diabetes. Type 2 diabetes is the result of eating poorly. It’s also the fastest-growing disease in the world, which, in Sugar’s camp, means they think it’s time for a shot at the title.

Fat—Like we stated earlier, fat is dense—it has a lot of calories for its size. It’s also an essential nutrient and helps us feel satiated or full. Therefore, when we’re hungry, we tend to crave it. And since we don’t really need much of it, it’s very easy to overeat. When we eat more food than we can put to good use, our bodies store it in adipose tissue. We call this tissue fat, or fat tissue. But it’s not really fat, as in the kind we eat. It’s something else. Well, it’s adipose tissue, but we’ve always called it fat. Anyway, the point is that we call it fat whether we get it from eating too much fat, too much protein, too much sugar, or too many carbs, or by drinking too much alcohol. And because of this, Fat gets a worse rap than it deserves.

But make no mistake, fat is formidable. We like fat. We like it a lot. Many fat-laden foods are considered delicacies. And we like fat so much that we’ve found ways to consume just the bad parts of fat that serve little to no dietary purpose. Stuff like butter, margarine, lard, and trans fats are completely unnecessary for our survival. Yet, somehow, our culture has taught us to crave such things. And these cravings have led to heart disease becoming the planet’s most popular way to kill people. Fat has been the undisputed champion of the obesity world for a long, long time. It’s not going to relinquish this title easily.

So let’s get ready to rumble!
Round 1: Smaller but faster, Sugar comes out in a rush and pummels Fat mercilessly. Because of The Kid’s smaller stature, Sugar’s punches seem to have little effect on The Champ. But Fat hardly lands a punch himself and is looking old and slow. Could The Hammer’s reign be over?

Round 2: The Sugar rush comes to a quick crash. The Champ, in no rush himself, seizes control of the pace and takes the round.

Round 3: All of our sponsors are major lobbyists on the side of Sugar. The Kid replenishes with some Gatorade and responds in another flurry of activity. The Champ is back on his heels, waiting for The Kid’s next inevitable crash.

Round 4: The Kid jabs, moves, and controls the pace, but The Champ seems unfazed. Fat knows that Sugar is only an effective nutrient during and immediately after activity, when blood sugar is being used up. So Sugar must keep moving, otherwise it has no nutrient value. The Hammer, being experienced, is willing to bide his time and wait for an opening.

Round 5: Sugar bobs and weaves, employing a psychological game that confounds The Champ. Complex carbohydrates and the simple carbs in fruit break down slowly and provide sustained energy during performance. This gives Sugar an advantage of public misconception because the junk food sugar can be lumped together with healthy carbohydrates. This underhanded attack is clearly something Fat hadn’t counted on. It seems to anger The Hammer.

Round 6: The Champ counters, big time. Two can play the public misconception card, and Fat uses its adipose tissue to absorb all of The Kid’s body blows. The statement that size matters seems to be holding true. In spite of nearly unending corporate support, Sugar seems to be tiring and its punches are growing less and less effective.

Round 7: Fat is now clearly in control of the bout and uses a cholesterol combo to further weaken The Kid. The Hammer’s corner men, Meat and Dairy, are loaded with it, and too much cholesterol is a major cause of heart disease. Could this spell the end for the gallant challenger?

Round 8: A savvy move saves The Kid, who notes that cholesterol is a necessary part of a healthy diet, and that with a proper ratio of fiber and complex carbs, it will have little negative effect. It’s a beautiful defensive move, but how long can it work? The Hammer just seems to be warming up his arsenal.

Round 9: Offended by The Kid’s trickery, Fat comes out smokin’ and unloads an entire 7-Eleven of chips, whipped cream, hot dogs, margarine, and even “vegetable” oils at The Kid. Since they all lead to heart disease, now the leading cause of death in the world, Sugar’s only defense is the rope-a-dope. He’s clearly in serious trouble.

Round 10: Down goes Sugar! The Champ plants a trans fat to the head and levels the challenger. This could be it, folks. The Kid staggers to his feet, but the referee has stepped in. He seems to be holding up a can of Crisco to see if Sugar can identify what hit him. If not, he’s going to stop it. Oh, but wait a minute! The Kid seems to be okay, and even looks to be smiling. The ref flashes a thumbs-up and the fight continues. Sugar dances away from a series of haymakers. The Hammer obviously wants to end the contest right now. But he can’t connect. The Kid survives! In his corner, he’s given a Coke.

Round 11: His face is bloodied, but The Kid is back at work. The Champ’s attack has been slowed with the news that the Food and Drug Administration has required that trans fat be listed on the side of every food label, while sugar, sugar alcohols, artificial sweeteners, and glucose syrups can be used with virtually no regulation. This tactic has clearly befuddled The Hammer, whose punches are beginning to miss more often than they connect.

Round 12: Ladies and gentlemen, we’ve got a new fight! Left for dead just a few rounds ago, Sugar is now controlling the pace. Still a long way behind on points, the challenger is using an intriguing combination that’s hurting The Champion. But The Champ fights back. The Champ first points out that many fats—the type in nuts, olives, seeds, avocados, fish, and many other foods—are essential for optimal health and then notes that nothing in sugar is needed for human survival; he then combines that with the fact that a “no fat” label can be on a food containing 100 percent sugar. Then he uses the fact that sugar alters the body’s pH levels, a clear example that an all-sugar food is far worse than a no-fat food. That’s gotta hurt.

Round 13: The credit probably goes to The Hammer’s corner men, all major corporate CEOs, but Sugar has got to be one of the craftiest fighters in history. He comes after Fat with polycystic ovarian syndrome (PCOS) and fibromyalgia, an offensive that clearly caught The Champ off guard. Apparently, they’re illnesses attributed in part to excessive sugar in one’s diet leading to insulin-resistance problems. The Hammer may have amassed enough points to win a decision but is now clearly on the defensive and reeling. Who knows what The Kid’s got up his sleeve at this point?

Round 14: With only one round to go, Sugar swings wildly with a combination of high fructose corn syrup (HFCS) and soda pop. This is one of the most lethal offensive combinations in the history of obesity! HFCS is the cheapest and lowest-quality sugar produced, and is now added to many items that aren’t even sweet—things like salad dressings and peanut butters, items once clearly in Fat’s corner. And soda, a substance with no nutritional value whatsoever, has become the singularly most consumed item on the planet. I don’t see how The Champ can survive this. He’s staggering around the ring, basically out on his feet! Somehow, and it must be experience, The Hammer avoids going down.

Round 15: It all comes down to this: one round to crown the World Champion of Obesity. Fat, the longtime champ, is clearly in trouble but still has enough points to win thanks to his mid-fight dominance. But Sugar has owned the latter rounds thanks to heavy lobbying, effective marketing, deregulation, and public misconception. The Champ was barely on his feet at the end of round 14, and his corner is working furiously to limit the damage. The question is, does Sugar’s corner have one last trick up its sleeve?

And here we go . . .: The Champ still manages to show some swagger, and comes out flashing heart disease as the number one killer, recently eclipsing lung disease and cigarettes—no slouch in the death department. But Sugar barely flinches and counters with type 2 diabetes, the fastest-growing illness in the world, that’s almost single-handedly controlled by Sugar. It’s like Ali’s “anchor punch” against Liston. And it sends The Champ sprawling. Down goes Fat! Down goes Fat!

And I don’t think the Champ will be rising from this one. Nope. Fat is out cold. The Hammer’s reign is over. There’s a new kid in town. Sugar is elated, dancing around the ring and pointing at the crowd, screaming, “I want YOU! I want YOU!” Ladies and gentlemen, introducing the NEW heavyweight champion of the obesity world: SUGAR!

Fat, Not Glucose, is the Preferred Fuel for Your Body

Dietary FatWhile we may consider ourselves to be at the pinnacle of human development, our modern food manufacturing processes have utterly failed at improving health and increasing longevity.

During the Paleolithic period, many thousands of years ago, our ancestors ate primarily vegetables, fruit, nuts, roots and meat—and a wide variety of it. This diet was high in fats and protein, and low in grain- and sugar-derived carbohydrates.

The average person’s diet today, on the other hand, is the complete opposite, and the average person’s health is a testament of what happens when you adhere to a faulty diet. Humans today suffer more chronic and debilitating diseases than ever before.

And there can be little doubt that our food choices play a major role in this development. Quite simply, you were not designed to eat large amounts of refined sugar, high fructose corn syrup, cereal, bread, potatoes and pasteurized milk products.

As Mark Sisson states in the featured article1:

“If you want to live a better life and eat the best foods nature provided for health and fitness, then it’s time to ditch the old paradigms and climb on to the primal approach to eating better.”

Is Glucose Really Your Body’s Preferred Fuel?

The notion that glucose is the preferred fuel for your body is a pervasive one. Everyone from diabetics to top athletes are advised to make sure they eat “enough” carbs to keep their systems from crashing. This is unfortunate, as this misguided advice is at the very heart of many of our current health failures.

As Mark so succinctly spells out in his article, FAT is actually the preferred fuel of human metabolism, and this can be traced back to our evolutionary roots.

Historically speaking, carbohydrate intake has always been quite low. Likewise, the diseases we now know are associated with insulin resistance—which is primarily caused by excess consumption of refined carbs—have been quite rare.

The evidence is both clear and overwhelming: Carbohydrate intake is the primary factor that determines your body’s fat ratio, and processed grains and sugars (particularly fructose) are the primary culprits behind our skyrocketing obesity and diabetes rates.

“It follows logically that if you can limit carb intake to a range of which is absolutely necessary (and even up to 50 grams a day over) and make the difference up with tasty fats and protein, you can literally reprogram your genes back to the evolutionary-based factory setting you had at birth – the setting that offered you the opportunity to start life as a truly efficient fat-burning organism and to continue to do so for the rest of your life as long as you send the right signals to your genes,” Mark writes.

Why the Low-Carb/High-Fat Diet Works for Weight Loss

Switching from a carb-based diet to a fat- and protein-based diet will help rebalance your body’s chemistry, and a natural side effect of this is weight loss, and/or improved weight management once you’re at an ideal weight. One explanation for this is that you don’t really get fat from eating too much and exercising too little. Nor do you get fat from eating fat. One researcher that has clearly established this is Dr. Richard Johnson, whose latest book, The Fat Switch, dispels many of the most pervasive myths relating to diet and obesity.

Dr. Johnson discovered the method that animals use to gain fat prior to times of food scarcity, which turned out to be a powerful adaptive benefit. His research showed that fructose activates a key enzyme, fructokinase, which in turn activates another enzyme that causes cells to accumulate fat. When this enzyme is blocked, fat cannot be stored in the cell. Interestingly, this is the exact same “switch” animals use to fatten up in the fall and to burn fat during the winter. Fructose is the dietary ingredient that turns on this “switch,” causing cells to accumulate fat, both in animals and in humans.

In essence, overeating and excess weight could be viewed as a symptom of an improper diet. It’s not necessarily the result of eating too many calories, per se, but rather getting your calories from the wrong sources. In simple terms, when you consume too many sugars and carbs, you set off a cascade of chemical reactions in your body that makes you hungry and craving for sweets:

  1. First, fructose is metabolized differently from glucose, with the majority being turned directly into fat because fructose stimulates a powerful “fat switch.”
  2. This rapidly leads to weight gain and abdominal obesity (“beer belly”), decreased HDL, increased LDL, elevated triglycerides, elevated blood sugar, and high blood pressure—i.e., classic metabolic syndrome.
  3. Dietary carbohydrates, especially fructose, are also the primary source of a substance called glycerol-3-phosphate (g-3-p), which causes fat to become fixed in fat tissue.
  4. At the same time, high carb intake raises your insulin levels, which prevents fat from being released.
  5. Fructose further tricks your body into gaining weight by turning off your body’s appetite-control system. Fructose does not suppress ghrelin (the “hunger hormone”) and doesn’t stimulate leptin (the “satiety hormone”), which together result in feeling hungry all the time, even though you’ve eaten. As a result, you overeat and develop insulin resistance, which is not only an underlying factor of type 2 diabetes, heart disease, and a long list of other chronic diseases.

The resulting equation is simple: fructose and dietary carbohydrates (grains, which break down into sugar) lead to excess body fat, obesity and related health issues. Furthermore, no amount of exercise can compensate for this damage because if you eat excessive fructose and grains—the primary ingredients NOT found in our ancestral diet—it will activate programming to cause your body to become, and remain, fat.

How Much Glucose or Carbs Do You Really Need?

The debate about whether or not you really need glucose, and if so, how much, is by no means settled. Earlier this year, I ran a series of articles featuring the back-and-forth discussion between two well-researched experts on this topic, Dr. Jaminet and Dr. Rosedale.

Dr. Jaminet is a proponent of so-called “safe starches,” and is of the conviction that depleting your glycogen store can stress other systems to provide the glucose your body requires to perform. Dr. Rosedale, on the other hand, points out that because glucose consumption will undoubtedly spike blood glucose levels and increase insulin and leptin, promoting resistance, glucose consumption is always associated with some incremental degree of damage and/or increased risk of mortality. His diet is subsequently extremely carb-restrictive.

Yet another diet similar to Drs. Jaminet and Rosedale’s is the GAPS diet, created by Dr. Natasha Campbell-McBride, which is specifically designed to help “heal and seal” your gut. As such, it primarily consists of easily digestible, lightly cooked foods that are high in protein, fats, and fermented foods, and low in fiber and carbs.

Mark Sisson also adds valuable insight to this discussion2:

“At any one time, the total amount of glucose dissolved in the bloodstream of a healthy non-diabetic is equivalent to only a teaspoon (maybe 5 grams). Much more than that is toxic; much less than that and you pass out. That’s not much range for a so-called “preferred” fuel, is it?

Several studies have shown that under normal low MET conditions (at rest or low-to mid- levels of activity such as walking and easy work) the body only needs about 5 grams of glucose an hour. And that’s for people who aren’t yet fat-adapted or keto-adapted. The brain is the major consumer of glucose, needing maybe 120 grams a day in people who aren’t yet on a low carb eating program.

Low carb eating reduces the brain’s glucose requirements considerably, and those who are very low carb (VLC) and keto-adapted may only require about 30 grams of glucose per day to fuel the brain… Twenty of those grams can come from glycerol (a byproduct of fat metabolism) and the balance from gluconeogenesis in the liver (which can actually make up to a whopping 150 grams a day if you haven’t metabolically damaged it with NAFLD through fructose overdosing).

Bottom line, unless you are a physical laborer or are training (exercising) hard on a daily basis, once you become fat-adapted, you probably don’t ever need to consume more than 150 grams of dietary carbs – and you can probably thrive on far less. Many Pbers [Mark’s diet, Primal Blueprint] do very well (including working out) on 30-70 grams a day.” [Emphasis mine]

Key Point: Replace Carbs with Healthful Fats

As I see it, this is really a non-issue for most people as few people anywhere near Dr. Jaminet’s recommendation of cutting carbs from the standard 50 percent down to 20-30 percent of total calories. However, if you’ve already begun to seriously address your carb intake then you may want to experiment with various amounts of “safe carbs” like rice and potatoes. As Mark describes, the actual amount of carbs could vary anywhere from 30 to 150 grams a day, depending on whether your body has adapted to burning ketones and your level of exercise.

Keep in mind that when we’re talking about harmful carbs, we’re only referring to grains and sugars, NOT vegetable carbs.

When you cut grain/sugar carbs you actually need to radically increase the amount of vegetables you eat since, by volume, the grains you need to trade out are denser than vegetables. You also need to dramatically increase healthful fats such as avocados, coconut oil, egg yolks, raw grass fed organic butter, olives and nuts.

You would not want to use highly processed and genetically engineered omega-6 oils like corn, canola and soy as they will upset your omega 6/3 ratio. Of course you want to avoid all trans fats, but contrary to popular advice, saturated fats are a key component of a healthy diet that will promote weight loss.

A reasonable goal will be to have as much as 50-70 percent of your diet as healthy fat, which will radically reduce your carbohydrate intake. It can be helpful to remember that fat is far more satiating than carbs, so if you have cut down on carbs and feel ravenous, this is a sign that you have not replaced them with sufficient amounts of healthy fat. Sources of healthy fats that you’ll want to add to your diet include:

  • Olives and Olive oil (for cold dishes)
  • Coconuts, and coconut oil (for all types of cooking and baking)
  • Butter made from raw grass-fed organic milk
  • Raw Nuts, such as, almonds or pecans
  • Organic pastured egg yolks
  • Avocados
  • Pasture finished meats
  • Palm oil
  • Unheated organic nut oils

Most people will likely notice massive improvement in their health by following this approach as they are presently consuming FAR more grain and bean carbohydrates in their diet, and any reduction will be a step in the right direction. To help you get started on the right track, review my Nutritional Plan, which guides you through these dietary changes one step at a time.

Recent Research Confirms Benefits of Low-Carb/High-Fat Diet

Conventional advice has focused on low-fat diets for weight loss and heart disease prevention, but again and again, studies demonstrate that this advice is diametrically opposed to reality… In one such study, researchers at Johns Hopkins University School of Medicine’s Heart and Vascular Institute compared the effects of two diets on vascular health; one low in fat, the other low in carbs. The study in question was presented at this year’s meeting of the American College of Sports Medicine in Denver, on June 33.

The study included a total of 46 men and women weighing on average 218 pounds. The six-month long weight loss program consisted of moderate aerobic exercise and strength training, and one of two diets, either:

 

  • Low-carb, high-fat: Less than 30 percent of calories from carbs (pastas, breads and sugary fruits), and up to 40 percent from fats (meat, dairy products, and nuts)
  • Low-fat, high-carb diet: Less than 30 percent of calories from fat, and 55 percent from carbs

The low-carb group on average shed 10 pounds in 45 days, while the low-fat group took 70 days to lose the same amount of weight. In terms of vascular health, the low-carb, high-fat dieters showed no harmful vascular changes, which is the primary reason for why so many are afraid of high-fat diets.

According to the lead investigator, professor of medicine and director of clinical and research exercise physiology, Kerry Stewart, Ed.D:

“Our study should help allay the concerns that many people who need to lose weight have about choosing a low-carb diet instead of a low-fat one, and provide re-assurance that both types of diet are effective at weight loss and that a low-carb approach does not seem to pose any immediate risk to vascular health. More people should be considering a low-carb diet as a good option.”

Stewart also believes that the emphasis on low-fat diets has likely contributed to the obesity epidemic in the US by promoting overconsumption of sugars and grains. I couldn’t agree more. The simple reason for this is that grains and sugars raise your insulin levels, which causes insulin resistance and, ultimately, weight gain, diabetes, and heart disease.

Listen to Your Body

The evidence is quite clear that chronically raising your blood glucose through consumption of grains and sugars will increase your insulin resistance, which in turn will increase insulin and leptin resistance. And avoiding insulin and leptin resistance is perhaps the single most important factors if you seek optimal health and longevity.

That said, the degree to which you choose to reduce carbs however is, ultimately, up to you. And certain individual biochemical differences can make one diet more beneficial for you than others. The key point is to be aware that consuming sugar, grains and starches will promote insulin resistance to some degree or other, depending on the amount you consume.

As always, remember to listen to your body as it will give you feedback if what you are doing is right for your unique biochemistry and genetics. So listen to that feedback and adjust your program accordingly.

10 Foods You Should Eat

Superfoods
We’ve all heard about superfoods—consumables with mystical powers to cure whatever it is that ails you and that will help you live forever. This list will be different. Today we’ll look at some common items that should be on your menu, even though you probably haven’t heard them touted as the next great miracle cure. In fact, some of these you probably thought were bad for you. I begin this list with a caveat; we’re all different. One person’s superfood is another’s trip to the emergency room (soy comes to mind here). There are some nutritional factors we all share, such as the need to eat a certain amount of calories that come from fats, proteins, and carbohydrates to keep our bodies functioning as they should. Beyond this, our exact dietary needs begin to diverge.

There are some obvious reasons for this. Lifestyle and activity level are pretty easy to understand. That someone who is pregnant or training for an Ironman needs more calories than a computer programmer who sits for 14 hours a day isn’t difficult to fathom. Neither is the fact that a 90-pound ballerina uses less fuel than a 350-pound lineman. That we all eat a different number of calories and a different percentage of fats, proteins, and especially carbs is obvious, or at least should be, since the bigger you are and the harder you work the more fuel your body needs to recharge itself.

What’s more subtle are body type differences. These can be difficult to understand, and many people never figure them out. Blood type, heredity, and other factors come into play and make each of us unique individuals. When it comes to eating, most of us spend a fair portion of our lives figuring out just what we should be eating to maximize our life experience (which doesn’t necessarily mean we choose the healthiest options). For this reason, there is no true “superfood.” There are, however, helpful foods that are specific to each of us. By experimenting with our diets, we will all find a course of eating that makes us feel better than anything else.

To help you begin your self-experiment, here’s a list of common foods that you’ll want to try. Most of these are very healthy for almost everyone, even though some have been vilified by society. This doesn’t mean that they’ll transform you into an epitome of health, but they’re certainly worth a try.

1. Peanut butter
I’m leading with this because I’m fairly certain peanut butter single-handedly kept me from getting chronic fatigue syndrome (CFS) during the no-fat 90s. In the early 90s, the average amount of fat in our daily diets plummeted while the incidence of CFS* (the colloquial veil for debilitating disorders marked by chronic mental and physical exhaustion) skyrocketed. This was particularly true among the otherwise healthy endurance sports sect. In the early 90s, my body fat was once recorded at 2 percent. Sure, I was ripped. Healthy? Not so much. I’m pretty sure that only my adherence to peanut butter as a healthy fat source kept my athletic obsession intact.

A bevy of modern studies now vindicates my opinion with science. Peanuts are high in both fat and calories but their fat has been associated with decreased total cholesterol and lower LDL and triglyceride levels. It’s also high on the satiation meter, meaning that a little can fill you up.

2. Cabbage
Every Asian culture, as well as European, eats more cabbage than we do and it’s time we thought about it more often than when we happen to splurge on P.F. Chang’s. Cabbage is absurdly low in calories and very high in nutrients. Among these is sulforaphane, which a Stanford University study showed as boosting cancer-fighting enzymes more than any other plant chemical.

3. Quinoa
This “grain” isn’t technically a grain at all. It just tastes like one. It’s actually a relative of spinach, beets, and Swiss chard. All of these are extremely healthy from a nutrient point of view, but quinoa is the only one that can fool you into thinking you’re eating a starch. It’s high in protein, minerals, vitamins, and fiber.

4. Spelt
This one is actually a grain but its origin is slightly mysterious. Some claim it comes from wheat while others say it’s a different species. Regardless, it has a high nutritional profile and can be eaten by many people with gluten intolerance, making it a good alternative to wheat products. Spelt can be found in many products, but as it’s still considered a “health food,” it’s off the major processing radar. Unlike wheat, if spelt is on the ingredients list, it’s probably good for you.

5. Walnuts
All nuts, really, but walnuts seem to be the king of the nut family. Used in Chinese medicine for centuries, walnuts are becoming more associated with Western health than ever before. A 2006 study published in the Journal of the American College of Cardiology found that eating walnuts after a meal high in bad fat could reduce the damaging effects of the meal.

6. Avocado
Another villain in the old no-fat movement, avocados are now thought to be one of the healthiest fat sources available. Beyond this, they have very high amounts of cancer-fighting antioxidants, and recent research seems to indicate that avocados’ phytonutrients may also help with the absorption of nutrients from other sources.

7. Mushrooms
The more we learn about phytonutrients—those that come in a small enough quantity to be missed on a food label (this is a layman’s definition only)—the more we should admire ancient cultures. These culinary delights have been feuded over for decades until, for some reason, we’d decided they were pretty much empty calories. The study of phytonutrients has taught us that warring over fungi may have held some rationale after all. Mushrooms are loaded with antioxidants and are thought to boost the immune system, help ward off some cancers, and have high amounts of potassium. Furthermore, researchers at Penn State University have found that mushrooms may be the only food to contain an antioxidant called L-ergothioneine.

8. Tea
Despite a ton of positive press over the last, oh, century, tea and coffee are still the devil’s brew in some circles. Perhaps even worse is how many coffee and tea restaurants have bastardized these natural brews into sugar- and fat-filled dessert items. Both tea and coffee, in their basic states, have no calories and many healthy benefits. Between the two, coffee is arguably more popular, most likely due to its higher caffeine content. But tea is probably healthier. Both have a high amount of antioxidants but stats on tea are almost off the charts. A recent study on calcium supplementation in elderly women, published in the American Journal of Clinical Nutrition, showed that bone mineral density at the hip was 2.8 percent greater in tea drinkers than in non-tea drinkers.

9. Cinnamon
Maybe the novel Dune was more prescient than we’ve given it credit for. After all, the plot revolves around an entire solar system at war over a cinnamon-like spice. Nowadays, we think of this as little but the flavoring in a 1,100-calorie gut bomb we find at the mall. But Frank Herbert knew a thing or two about history and cinnamon has long been the prized possession of the spice world. It has a host of benefits, but perhaps none more important than this one: USDA researchers recently found that people with type 2 diabetes who consumed one gram of cinnamon a day for six weeks significantly reduced their blood sugar, triglycerides, and LDL cholesterol. “He who controls the spice controls the universe!”

10. Natto
This is on the list because, for one, it’s one of the few foods I’ve eaten that I truly don’t like. But mainly, it’s here because we’ve really messed up the way we eat soy. Natto is fermented soybeans and very popular in Japan, which is where I had it. It’s becoming more popular here and this is most likely due to its health benefits. Nearly all the soy options we’re offered in the U.S. are non-fermented. The list of health benefits of fermented soy is a mile long. It’s associated with reducing the risk of cancer, minimizing the likelihood of blood clotting, aiding digestion, increasing blood circulation, an improved immune system, improving bone density, lessening the likelihood of heart attacks, more vibrant skin, and reducing the chance of balding. And it also has strong antibiotic properties, among other things. So you might want to ditch the soy crisps, soy ice cream, and your iced soy mochas and add some natto to your diet.
