The truth about whole grains 7/12

The truth about whole grains 7/12

Quiz: What are amaranth, emmer, and teff? No, they’re not celebrity baby names. Along with millet, quinoa, and rye, they’re part of a class of food commonly referred to as “ancient grains.” Although they represent some of the oldest plants consumed by humans, for many Americans they’re a new and healthier way to eat.

Ancient grains offer health benefits

While many are true cereal grains, several—such as amaranth, buckwheat, and quinoa—actually originate from broadleaf plants. But they offer the same health benefits, such as helping to prevent cancer, heart disease, and high blood pressure. And when eaten as a whole grain, most are high in fiber.

According to the U.S. Department of Agriculture’s dietary guidelines, at least half of all grains eaten each day should be “whole”—that means the intact, ground, cracked, or flaked grain. Most of us limit our grains to barley, corn, oats, rice, and wheat, but you can add variety to your diet by including some ancient grains. And it could make it easier to eat the recommended 3 ounces of whole grains daily. Additionally, several varieties are sources of high-quality protein.

Eight widely available ancient grains

Below are listed eight of the more widely available ancient grains, often sold in health-food stores, online, and sometimes at your local grocery store. Most can be found in whole-grain form. (Find tips on eating whole grains here.)

One of the earliest known food plants, it was cultivated by the Aztecs and the Incas (one of the best-known varieties is called Inca wheat). High in protein and a range of nutrients, including calcium, folic acid, magnesium, and potassium, it’s as simple to make as rice. Traditionally eaten as a breakfast porridge, it can also be cooked and added to salads, pancake batter, and soups, or eaten as a side dish.

Despite its name, it’s not a type of wheat, but provides lots of protein as well as calcium, iron, manganese, potassium, and zinc. Native to Southeast Asia, buckwheat is common in Eastern Europe and Asia. The flour is used to make various foods, including pancakes and soba noodles. The grains, or groats, can be tricky to cook, so follow directions carefully. Cooked groats are a great addition to side dishes and salads.

Farro (or emmer)
One of the first crops domesticated in the ancient Near East, whole kernels and flour are full of fiber, iron, magnesium, niacin, and zinc. It can be served in salads, side dishes, and baked goods.

One of the earliest cultivated crops, it is a staple in Africa, China, and India. High in magnesium, whole cooked millet can be served as a side dish or added to soups. When popped it can be eaten as a snack. Millet flour can be used in baking. 

Grown in the Andean region of South America, this ancient seed was named the “mother of all grains” by the Incas. It provides high levels of complete protein and is rich in iron, phosphorus, and potassium. Quinoa may require a thorough rinse before cooking to wash off its naturally bitter coating (called saponin). It cooks in about 15 minutes and can be served as a side dish or added to soups and salads.

Don’t expect this grain to taste like rye bread, which often takes on the distinct flavor of the added caraway seeds. While rye flour is used to make breads and crackers, rye grains can be served hot as a side dish or added to soups and salads. Soaking overnight shortens the cooking time. Rye is high in nutrients, including folic acid, iron, magnesium, phosphorus, potassium, riboflavin, and zinc.

Widely popular in Africa, it’s high in fiber, niacin, and phosphorus. In India it is used to make chapatis (a type of flatbread). In the U.S., it’s most often ground into flour and used in baked goods. 

Teff (or tef)
One of the tiniest grains, with seeds smaller than a pinhead, it’s high in calcium and vitamin C. In Ethiopia teff is ground into flour and made into a soft, spongy bread called injera. Teff can also be found in cereals and can be sprinkled on salads or added to soup.

Fiber Made Simple

Fiber Made Simple

Let’s talk fiber. Do we really need as much as doctors claim? If so, how much? Can we get too much? Will it prevent cancer? Are grass-fed steak and whole eggs good sources of fiber? How the heck do I get rid of this constipation?
This is just a sampling of the many questions I get regarding dietary fiber.
What is Dietary Fiber?
Fiber is a complex carbohydrate made up of non-starch polysaccharides, resistant starches, and/or cellulose. In simple terms, when you hear fiber, think plants, namely veggies, fruits, and whole grains. Just as we have cells that give our body structure, so do plants. (Don’t eat humans, though. They don’t provide fiber.) These plant cells can hold nutrients, water, and other things. There are essentially two kinds of fiber. Each is unique, and possesses specific beneficial qualities.

Soluble Fiber

Fiber Made Simple

This type is very resistant to breakdown by the digestive enzymes in your mouth, stomach, and small intestine. Gums, pectins, and inulin are in this category.
Gums stabilize food, giving it more of a shelf life. They also add texture to food. Probably most importantly, they slow down the absorption of glucose.
Pectins are a little different in structure than gums. They’re more acidic, aiding in the absorption of certain minerals like zinc. Similar to gums, they also lower blood sugar levels. Probably the most well known source of pectin is apples. They’re the source for many commercial pectin formulations.
Inulin is a FOS, or fructooligosaccharide. If you read my article on digestion you’d know that inulin is a pre-biotic that feeds the good bacteria in your stomach. When I noticed this was in Metabolic Drive®Muscle Growth, I did cartwheels (figuratively, of course). When you see foods containing FOS in the chart below, take note.
You’ll generally find soluble fiber in fruits, beans, barley, oats, and some other sources. It does get digested – sort of – but not until it hits the large intestine, where good bacteria ferment it, producing butyric acid (found in butter) and acetic acid (found in vinegar). This helps the digestive system maintain its acidity.
Some soluble fibers provide a bit of energy, about two calories per gram; likely not enough to get you through a particularly harsh drop-set on the leg press. Others such as gums are non-caloric.
So what are the key benefits to soluble fiber? There are three that warrant attention.

Three Key Benefits of Soluble Fiber

Stabilizes blood sugar. Soluble fiber slows down transit time (the time it takes for food to enter and leave the body) and encourages a more gradual breakdown of food. Specifically, it slows down the emptying of the stomach and the digestion of starches (and subsequent entry of glucose into the blood stream). Since glucose absorption will be slower, you can avoid the blood sugar ups and downs.
I’ve even heard of people mixing guar gum with water before meals to accomplish this. If you’re a diabetic, you should consider this before you opt to skip the veggies. Eating your veggies could mean you’ll need less insulin.
Lower LDL levels. When short chain fatty acids are made as a result of the fermentation of soluble fiber, it appears to result in a decrease in LDL levels. Good news for those concerned about cardiovascular disease.
Increased defense against cancer. Fiber can bind with cancer-producing compounds and remove them from the body, rather than letting them hang around to wreak havoc. Also, as fiber is fermented into short chain fats like acetic acid in your intestine, it helps the colon maintain its pathogen-killing acidity.

Insoluble Fiber

Fiber Made Simple

This type of fiber doesn’t get digested anywhere. It’s essentially lignin, cellulose, or hemicellulose, and you’ll typically find it in wheat or veggies. Its job is to simply carry food and water through the digestive system.
Unlike soluble fiber, insoluble fiber doesn’t dissolve in water. This means that it swells up like a sponge, and adds bulk to the stool. This makes your feces move faster through your intestines (called intestinal hurry). There are several key benefits to insoluble fiber.

Three Key Benefits of Insoluble Fiber

Less constipation. Since insoluble fiber adds bulk to your stool, it aids in elimination, resulting in less constipation. One of the most common complaints I hear from dieters is that they’re constipated. If you’ve ever competed in bodybuilding, you know what I mean. It happens to almost everyone, and can be very problematic. I go so far as to consider it a sort of “silent killer,” like high blood pressure. There are many studies that demonstrate adding raw bran decreases intestinal transit time. Constipation and the non-evacuation of waste tie directly into the next point.
Toxic waste dump clean up. When your colon doesn’t completely evacuate, or when bad bacteria begin to dominate the good bacteria, putrefaction occurs. This means that toxic substances can get reabsorbed back into the blood and other tissues. By binding with toxins and hormones, insoluble fiber is very good at keeping you “cleaned out.” The payoff is that without so much of these toxins and hormones sitting around in your gut, you’ll be better protected against bowel diseases, cancers, and other maladies.
Note: You may have heard of the “fiber hypothesis.” It means that a low intake of fiber promotes certain diseases such as high blood pressure, obesity, colon disease, and 30-40 other diseases, while a high fiber intake protects you against them. If you’re a research junkie, look up the work of Drs. Denis Burkitt and Hugh Trowell. Their work in Africa is what formed this hypothesis.

How much do we need and where do find it?

First, you shouldn’t rely on fiber supplements. I believe it’s best to get your fiber from a wide variety of whole food sources that contain different types of fiber. One of the major benefits of dietary fiber is that the phytonutrients, antioxidants, vitamins, minerals, etc., within the food choice often accompany it. This is also what makes fiber research problematic. Which of these factors is helping the most? Or is it all these things working in concert that prevent disease? It’s a tough call.
For how much should we eat, the common recommendation is 25-35 grams a day, with some experts saying around 40 grams. It’s recommended that diabetics get upwards of 50 grams a day.
When determining your needs remember that as a weight training athlete, you’re probably eating way more protein, fat, etc., than the “normal” person these recommendations were designed for. In all likelihood, fiber is simply one of those things that you have to play around with until you get it right. When you’re passing soft bowel movements a few times a day without reliving the dinner scene from Alien, you’re probably there or well on your way.
So now that we’ve covered the fiber basics, where do we find it? Here’s just a sampling to get you started.

Whole grains

Whole oats contain a type of soluble fiber called beta-glucan, a gummy soluble fiber. Studies demonstrated a lowering of cholesterol from this type of fiber, hence Quaker’s label claims that oats reduce cholesterol. Oat bran is also very popular due to its insoluble fiber content.
Rice bran is an interesting fiber source. According to Dr. Ann Gerhardt, it’s been shown to lower LDL levels.
Cocoa Bran sounds tasty. This is the outside layer of the cocoa bean. According to Dr. David Jenkins of the University of Toronto, it’s been shown to protect against oxidized cholesterol and raise HDL.
Konjac mannan is another interesting fiber. It contains a high concentration of glucomannan. I’d never even heard of this until I recently bought some “Miracle Noodles.” Turns out that researcher Dr. Hsaio-Ling Chen has also been using this type of soluble fiber to lower LDL levels.
Buckwheat. I had to add this whole grain as many don’t understand that it’s completely unrelated to wheat. The nice thing is that even with buckwheat flour, you still get the good parts of the seed.


Beans, lentils, peas, and peanuts are all part of the legume family. Beans in particular are a great source of both soluble and insoluble fiber. My favorite are black-eyed peas (not the band).
I toss them in rice, add a cayenne-based hot sauce, and it’s pure awesomeness. If you’re concerned about flatulence because you’re in a new relationship or work around a lot of exposed flames, you have to give beans a few weeks to work. They contain loads of soluble fiber, which means it’s going to get fermented in the large intestine. This is a good thing. Be patient and your flora will adjust.


Fiber Made Simple
Pectins are common in fruits, and being a soluble fiber get fermented in the large intestine, thus producing short chain fatty acids. Fruit also contains cellulose much of the time, an insoluble fiber that will keep things moving.


You may have heard about “phytates” in nuts, which are anti-nutrients that bind with certain minerals that cause a depletion of that mineral. Here’s my take: in a well-balanced diet, it’s not something worth losing sleep over. If you’re concerned, I suggest soaking the nuts until they begin to sprout, and then dry them again. Sprouting breaks down the phytate into inositol and phosphate. You’re good to go.


I should also mention a few seeds. Flax seeds are very high in fiber, 7 grams per tablespoon, and have a portion of lignan (insoluble fiber type), which have been reported to be cancer protective. Sesame seeds are popular too, but have the phytate issue to contend with. As stated, I wouldn’t worry about this, as a strong case could be made that phytates are also cancer protective.


The first thing people usually associate with fiber are veggies, and for good reason. My favorites are spinach, kale, asparagus, and broccoli.
Every good nutrition article needs a chart to help make sense of all the information. Ask and you shall receive!

  • If you’re thinking that simply adding fruit to your diet will relieve constipation, think again. Most of the fiber in fruit is soluble and thus broken down in the colon and doesn’t really have the bulking effect of cereal fibers like wheat bran.
  • Be very careful with fiber if you have an intestinal disease like Crohn’s disease. High amounts of fiber can aggravate it.
  • It’s possible that even a perfect diet will not relieve constipation problems.

So what else can we do to ensure we stay “regular?”

  • Drink a lot of water!
  • Move around, exercise. When I was in the hospital, my digestive system was essentially asleep after my digestive surgeries. The doctors were on me 24-7 about walking to wake my system up. I must’ve clocked 50 miles walking the halls of the Mount Carmel Medical Center.

These things aid in a faster transit time, which means it can help solve constipation problems.

The Straight Poop

When you’re new to the iron game, all you want to learn about is the training side of the equation like sets, reps, and exercises. You know, the fun stuff. But as you progress and graduate from white belt to yellow or blue belt, you soon learn that the nutrition side is just as important to bodybuilding success, if not more.
Moving beyond good nutrition is the pursuit of long-term health and vitality. While not sexy or exciting – what, fiber isn’t exciting? – topics that prioritize health may be the most important of all. Because the strongest, most jacked physique on the stage or at the beach can still be a ticking time bomb if care isn’t taken to keep key health markers in check.
That’s the next level of enlightenment, when you marry a love for the iron with sound bodybuilding nutrition and lifestyle practices that promote lasting health and vitality. That’s when you graduate to black belt. That’s the level I hope all T NATION readers aspire to.
I’ll see you there!


The Truth About Fiber

True or False: All Fiber is Created Equal
FALSE: There are two basic types of fiber, with different functions. Insoluble fiber is found in wheat bran, nuts, and many vegetables. Its structure is thick and rough, and it won’t dissolve in water, so it zips through your digestive tract and increases stool bulk. Soluble fiber is found in oats, beans, barley, and some fruits. It dissolves in water- to form a gel-like material in your digestive tract. This allows it to slow the absorption of sugar into your bloodstream. What’s more, soluble fiber, when eaten regularly, has been shown to slightly lower LDL (bad) cholesterol levels.

True or False: Fiber Has No Calories
FALSE: Fiber is essentially composed of a bundle of sugar molecules. These molecules are held together by chemical bonds that your body has trouble breaking. In fact, your small intestine—can’t break down soluble or insoluble fiber; both types just go right through you. That’s why some experts say fiber doesn’t provide any calories. However, this claim isn’t entirely accurate. In your large intestine, soluble fiber’s molecules are converted to short-chain fatty acids, which do provide a few calories. A gram of regular carbohydrates has about 4 calories, as does a gram of soluble fiber, according to the FDA. (Insoluble fiber has essentially zero calories.)

True or False: Fiber Can Help You Lose Weight
TRUE: Fiber’s few calories are more than offset by its weight-control benefits. The conclusion of a review published in the journal Nutrition is clear: People who add fiber to their diets lose more weight than those who don’t. Fiber requires extra chewing and slows the absorption of nutrients in your gut, so your body is tricked into thinking you’ve eaten enough, says review author Joanne Slavin, Ph.D., R.D. And some fibers may also stimulate CCK, an appetite-suppressing hormone in the gut.

True or False: Fiber is All-Natural Goodness
SORT OF: Fiber is showing up in everything these days—yogurt, grape juice, artificial sweetener. If this seems impossible, remember that these are molecules; you don’t have to see or feel fiber for it to be present. Scientists now have a new class of fiber they refer to as “functional” fiber, meaning it’s created and added to processed foods. “You can make fiber from bacteria or from yeast,” says Slavin. “And as long as you prove that it can lower cholesterol or feed the good bacteria in your gut or increase stool weight, it’s fiber.

True or False: Supplemental Fiber is Healthy
TRUE: Foods with added fiber don’t necessarily provide the benefits you might expect. Inulin, for example, a soluble fiber extracted from chicory root, can be found in products like Fiber One bars. In addition to boosting fiber content, it’s also commonly used to replace fat. Inulin is known as a prebiotic, which means it promotes the growth of healthy bacteria in your gut. That’s good, of course. “But,” says Slavin, “inulin doesn’t have the same cholesterol-lowering effect as the fiber found in oat bran.”

True or False: Food Companies are Jumping on the Fiber Bandwagon
DUH: In 2007, the FDA declared that polydextrose can be called fiber. Polywhat? Polydextrose is made from glucose, sorbitol (a sugar alcohol), and citric acid. It’s what puts the fiber in Fruity Pebbles (not actual pebbles). Polydextrose received FDA approval because it mimics some attributes of dietary fiber: It isn’t absorbed in the small intestine, and it increases stool weight. Polydextrose mainly bulks up foods so they’re not as high in calories. However, there’s no research to prove that polydextrose is as beneficial as the fiber found in whole foods.

True or False: Fiber Helps Prevent Colon Cancer
MAYBE: This idea arose in the 1960s when it was noted that fiber-scarfing Ugandans rarely developed colon cancer. But nearly five decades later, it still hasn’t been proven.

In 1999, Harvard researchers found no link between dietary fiber intake and colon cancer. But a European study that tracked more than a half million people correlated a high-fiber diet with up to a 40 percent reduced risk of colorectal cancer. Then a 2005 review in the Journal of the American Medical Association found that people who ate the same amount of fiber as those in the European study didn’t experience any benefit. The American Institute for Cancer Research calls protection “probable.” This controversy aside, high-fiber diets are associated with preventing many chronic diseases, so it’s smart to boost your intake, says Arthur Schatzkin, M.D., Dr.P.H., of the National Cancer Institute

True or False: You Need 38 Grams of Fiber a Day
FALSE: That’s the recommendation from the Institute of Medicine. Scientists there crunched data from three studies and squeezed out the number 38 in 2005. It equals 9 apples, or 12 bowls of instant oatmeal. (Most people eat about 15 grams of fiber daily.) The studies found a correlation between high fiber intake and lower incidence of heart disease. But none of the high-fiber-eating groups in those studies averaged as high as 38 grams, and, in fact, people saw maximum benefits with a daily gram intake averaging from the high 20s to the low 30s. Also, it’s worth noting that these studies don’t show cause and effect, and that unless you’re taking a supplement, it’s hard for even those who eat the healthiest of diets to consume 38 grams of fiber. It’s fine to shoot for that amount, but you’re certainly not failing if you don’t meet it.

True or False: This is Complicated
FALSE: A simple strategy: Eat sensibly. Favor whole, unprocessed foods. Make sure the carbs you eat are fiber-rich—this means produce, legumes, and whole grains—to help slow the absorption of sugar into your bloodstream. “The more carbohydrates you eat, the more fiber becomes important to help minimize the wide fluctuations in blood-sugar levels,” says Jeff Volek, Ph.D., R.D., a nutrition researcher at the University of Connecticut.


Diabète: les grains entiers réduiraient le risque de mourir d’une maladie cardiovasculaire

18 mai 2010 – La consommation régulière de céréales à grains entiers contribuerait à réduire le risque de mourir d’une maladie cardiovasculaire, chez les personnes atteintes de diabète de type 2. Les troubles cardiovasculaires constituent la principale cause de mortalité chez les diabétiques.
C’est ce qu’indiquent les résultats d’une étude épidémiologique1menée durant 26 ans auprès de 7 822 Américaines souffrant du diabète de type 2. Durant toute la période d’observation, les participantes répondaient régulièrement à des questionnaires visant à analyser en détail leur régime alimentaire : la nature, la composition et la quantité des aliments consommés.
Les résultats indiquent que le taux de mortalité associé aux troubles cardiovasculaires chutait de 35 % chez les participantes qui consommaient le plus de grains entiers comparativement à celles qui en consommaient le moins. Chez celles qui consommaient le plus d’aliments enrichis en son, le nombre de décès d’origine cardiovasculaire diminuait de 65 %. Quant au risque de mourir prématurément de « toutes causes confondues », il était réduit de 28 %.
Les céréales à grains entiers sont riches en fibres diverses, notamment en son. Cette dernière fibre est généralement retirée des céréales du commerce, sauf lorsqu’il est spécifié qu’il s’agit d’une céréale à grain « intégral ». On trouve aussi des aliments qui sont enrichis en son.
Les chercheurs croient que les fibres céréalières, principalement le son, et les divers phytonutriments qu’elles renferment contribuent à la maîtrise de la glycémie et au maintien de l’intégrité de la paroi interne des vaisseaux sanguins.
