Food Factors and Athletic Performance

Food Factors and Athletic Performance

By Roger D. Deutsch


Eating healthful food is one thing, but eating in accordance with your own, unique, genetically determined biochemical makeup, is quite another thing.

One man’s meat is another man’s poison. Finding out what foods are right (and which are wrong) for you, is the key to health and performance.

Foods that are compatible with your make up will increase your strength and energy. Consumption of foods or added chemicals that YOUR body perceives as harmful will result in intolerance reactions. Food intolerance induces the excessive generation of toxic free radicals and inflammatory chemicals. The damage can result in a wide range of health problems. The following are some of the effects of food intolerance that are of strong interest to athletes:

1. Direct damage to the mitochondria in our cells. The mitochondria are the site where energy is produced. The wrong food activates the immune system and free radicals and attacking molecules produced can cause damage to the DNA, and other structures within the mitochondria, resulting in lower energy production. This is of special significance to athletes because intense exercise alone will generate damaging free radicals from normal metabolic process speed up somewhat by the intensity of the exercise. Usually this is not a problem if your anti-oxidant enzymes and nutritional anti-oxidants are sufficient. Complicate it with food intolerance and the generation of free radicals will overload your systems.

2. Related in some ways to this is that inflammation will also cause a shortening of the ends of the strands of your DNA called telomeres. Telomeres are like the plastic pieces at the end of a shoe lace, holding the DNA strands together. Whenever the cell divides, and immune cells divide frequently, the telomeres are shortened. When they become too short the cell can no longer reproduce; becomes old and dies. This could explain cancer and generalized weakened immunity in old age. Avoid this by avoiding inflammation. We can choose what we eat.

3. Auto-immunity can also arise from too much inflammation. How, some immune cells die in the process of trying to neutralize a food. The DNA from the dead cells release their own genetic material, which, if it is too great may become itself perceive as a “foreign” body the immune system must attack. However, this time you are attacking the blueprint for you own bodily proteins (structures) and auto-immune reacts may occur. Again, it’s better to avoid this if you can.

4. Certain immune chemicals with names like Interleukin 6, and tumor necrosis factor alpha, will block insulin receptors on your muscle (and brain and liver) cells. This is a recently discovered finding made by medical scientists which explains why food intolerance makes people fat. The muscles cells are starved of important energy material which is instead stored as fat in fat cells.

5. Food intolerance can cause inflammation in the gut. An extreme form is celiac disease. This reduces the absorption of nutrients that are needed for proper energy production as well as all other biologically processes. It also consumes serotonin in the gut. Serotonin deficits are related to sugar craving.

6. Toxic immune chemicals – such as elastase- damage muscle tissue.

7. Food intolerance can cause inflammation in the upper and lower airways. Decreased air intake limits aerobic metabolic function.

8. Chronic inflammation also makes you fatigued. Ever wonder why you feel so tired when you get the flu? It’s because the same immune chemicals that are intended to fight viruses cause fatigue so that you are forced to rest when you are sick. Your body wants you to rest, not exercise, so that your energy can be used to fight the invader. The immune system that’s inappropriately activated by the wrong food will thus cause you to be chronically fatigued to a lesser or greater extent. The immune system is now mistaking a food particle for a virus or bacterium.

In contrast with, “True” allergy, whereby, a few molecules of peanut may, for example, induce anaphylaxis, the sheer magnitude of exposures to intolerogenic foods, despite it’s less dramatic flare (pun intended) render FOOD INTOLERANCE FAR MORE COMMON.


Allergy vs. Intolerance

The biological cause of true allergy has been known since 1967. An immune system structure called, IgE, plays a central role. A small amount of allergen, interacting with IgE, can trigger the release of chemicals that create allergic symptoms. Many people react to animals, pollens; and, in rare, unfortunate cases, foods.

Food allergy symptoms are quite dramatic, and intentionally so, as this pathway represents our natural defense against large parasites, like helminths. Unlike other pathogens (i.e., viruses, bacterium) these parasitic worms are significantly larger than the cells that protect against them. Hence, our immune defense against must be very strong, which is why allergy produces such dramatic symptoms.

In contrast, intolerances to foods follow different pathways, and symptoms are dose related, chronic and delayed. Consequently, most people are unaware of their food intolerances.

Offending food may be tolerable until such time as a chemical naturally occurring within the food, or that has been added, exceeds a certain threshold. Many athletes are consuming energy bars that are complex. The modern diet is, in general, very complex and certainly not what our ancestors have been exposed to for sufficient time for us to adapt. Hence, even “normal” foods may be simply unfamiliar to us, from a genetic point of view, and aggravate the immune system.

Another consequence of the modern diet is that nutritional cofactors required for hepatic biotransformation are lower in commercially grown produce. When chemicals in foods (naturally occurring or otherwise) cannot be adequately detoxified by the liver, the immune system is called to action.

This “total load” is further impacted by the integrity of the gut membrane which, under normal circumstances, forms a natural barrier. Infection, an imbalance in gut flora, antibiotics, cortisone (exogenous or endogenously produced by excessive stress) and hormones used in birth control, compromise the gut barrier.

Classical, or IgE allergy to food, has been recognized for centuries. The first recorded anaphylactic reaction to egg occurred in the sixteenth century (1) and fish induced allergy was reported in the seventeenth century. However, the more recent development of other non-allergic adverse reactions to foods, including food intolerance, only began receiving recognition following the work of Chicago based allergist, Theron Randolf, in the 1950’s(3).


Modern agriculture causes modern diseases; inflammation

The link between food intolerance, chemical sensitivity and the dramatic increase in degenerative diseases is clear; coinciding, as it does, with consumption of junk food. When low quality and non compatible foods are avoided, inflammation resolves, weight normalizes, and a number of other inflammatory based health problems subside.

As seen from this necessarily simplified analysis, adverse food reactions may be toxic or nontoxic reactions. Toxic reactions occur in anyone, given sufficient exposure. Nontoxic reactions occur in susceptible individuals and may result from chemicals occurring in aged cheese, chocolate; and may involve either immune mechanisms (allergy or hypersensitivity) or non- immune mechanisms. The former are referred to as, “hypersensitivities” the latter, “intolerances”.

Food intolerances are the most common. They are most likely caused by the pharmacologic activities of chemicals that naturally occur in the food; or, that are added to the food.

However, some intolerances result from inherited enzyme deficiencies, and thus remain fixed. Some reactions are exacerbated by poor digestion related to intestinal disoders, or the overwhelming of specific detoxification pathways, that are rate limited. (4) Hence, addressing these underlying issues can result in tolerance of moderate quantities of the food.

Because numerous and varied mechanisms play a role in the pathogenesis of adverse reactions to foods definitive identification of offending foods relies upon provocation of symptoms following oral challenge under double blind conditions- not always a convenient option for a training athlete. Various serum tests exist but are of questionable value. Whereas testing serum levels of allergen specific IgE is a useful test for classical allergy, it is of limited value for identification of foods and chemicals associated with intolerance that are not IgE mediated. Rather, a useful test for intolerances would have to measure the direct effect of the food substance on the very immune system cells that are responsible for these intolerances. It should show a good correlation with clinical symptoms, as confirmed by double blinded oral challenges. The only test meeting these criteria is the Alcat test. The Alcat test was developed by scientists working in the US in the mid ‘80’s. It has since spread throughout the world and is now available in Germany. It has begun to start a revolutionary breakthrough in sports and general medicine that many have not yet come to terms with. However, it’s many benefits are well documented.


Other Manifestations

Previously, childhood diabetes was exclusively of the Type 1, auto-immune based type. The consequence: high blood sugar levels and tissue degeneration. Perhaps this is just the tip of the iceberg. Now, due to over activation of the innate immune system, due to food intolerance, so called, “adult onset” diabetes occurs even in children. Adult onset diabetes is not auto-immune per se, but occurs when insulin receptors on muscle, liver and brain, lose effectiveness. Insulin resistance is the hallmark of metabolic syndrome. Initially, insulin is produced, but it cannot sufficiently facilitate the uptake of glucose because of the insensitivity of the insulin receptors. The pancreas then produces increasing quantities of insulin but of lower quality. Blood sugar levels increase.

Interleukin 6 and tumor necrosis factor alpha block insulin receptors. Glucose is stored in adipocytes (fat cells) which in turn produce these very same mediators perpetuating the cycle of inflammation, muscle degeneration, and inefficient metabolism.


Solutions


The foremost approach to achieving health, leanness and improved energy and strength should be dietary; emphasizing healthy, natural, nutritious food along with exercise, stress management, intestinal health and adequate nutrition.

Foods that act as triggers require proper identification and avoidance. Testing of white blood cell reactions, is the best approach. It reflects pathological responses to foods that are mediated by immunologic, non-immunologic, pharmacologic as well as toxic pathways. The Alcat test is a scientifically validated approach that exhibits the highest degree of correlation with blinded challenges and is the most accurate. (5) Symptom resolution, normalization of weight, and broad clinical correlation, affirm this as a most beneficial tool to be added to any health and sports regimen. (6)

10 Everyday Super Foods

10 Everyday Super Foods

These easy-to-eat foods are packed with multiple nutrients to help you stay healthy.

By Kathleen M. Zelman, MPH, RD, LD

WebMD Weight Loss Clinic-FeatureReviewed by Louise Chang, MD If only there were some kind of potion or pill that had everything you needed for weight loss and good health. Unfortunately, no such pill exists, but there is a solution -- something that not only promotes wellness and weight control but tastes good, too. These multitasking "super foods" provide multiple disease-fighting nutrients, fill you up so you can enjoy plenty of food without excess calories, and are easy to include in everyday meals. After all, what good is a super food that is hard to find, difficult to prepare, and the kids won't eat?

Eaten regularly, these foods will help you satisfy the recommendations of the U.S. government's 2005 Dietary Guideline, giving you nutrients that are typically missing from American diets. According to the Guidelines, Americans need to eat more fruits, vegetables, whole grains, and low-fat dairy products.
Of course, experts are quick to point out, this list of top 10 super foods by no means includes all the nutritious foods that should be part of a healthy diet.

"What is ultimately the most important to good health is a dietary pattern that includes all these foods, along with a wide variety of other nutritious foods and regular physical activity," says Tufts University researcher Alice Lichtenstein, DSc.

And don't forget that portion size matters, even when it comes to healthy foods. You can take more liberties when eating simply prepared vegetables, but you should take care to eat other super foods in sensible portions.

"Foods like nuts are nutrient rich, but if you overeat them you can pack on the pounds, and that defeats the purpose," says Elisa Zied, MS, RD, author of Feed Your Family Right

Top 10 Multitasking Super Foods


1.Low fat or fat-free plain yogurt is higher in calcium than some other dairy products and contains a great package of other nutrients, including protein and potassium. It can also be enhanced with other good-for-you substances. "Yogurt is a vehicle food that can be enriched with probiotics for a healthy balance of bacteria in your gut, and beneficial, heart-healthy plant stanols," says Zied. "And lactose sensitive people may tolerate yogurt better than milk." Look for plain yogurt fortified with vitamin D, and add your own fruit to control sweetness and calories. Versatile yogurt can also be used in entree and bakery recipes, in dips for veggies, etc. Don't like yogurt? Skim milk is another super dairy food that has only 83 calories per cup and is easy to slip into coffee to help you get one of the recommended three servings of dairy each day. "Dairy foods contain practically every nutrient you need for total nutrition -- and in just the right balance," says bone health expert, Robert Heaney, MD. "No other food group in the diet is as complete or as economical."

2.Eggs make the list because they are nutritious, versatile, economical, and a great way to fill up on quality protein. "Studies show if you eat eggs at breakfast, you may eat fewer calories during the day and lose weight without significantly affecting cholesterol levels," says Elizabeth Ward, MS, RD, author of The Pocket Idiot's Guide to the New Food Pyramids. Eggs also contain 12 vitamins and minerals, including choline, which is good for brain development and memory. Enjoy them at any meal or hard-cooked as a portable snack.

3.Nuts have gotten a bad rap because of their high fat content. But their protein, heart-healthy fats, high fiber, and antioxidant content earn them a place on the top 10 list. The key to enjoying nuts, experts say, is portion control. "All nuts are healthful in small doses, and studies show they can help lower cholesterol levels and promote weight loss," says Today Show nutritionist Joy Bauer, MS, RD. "I like pistachio nuts because they also contain plant sterols and it takes longer to crack the shell and eat them, making it easier to control the portion. Whether you prefer pistachios, almonds, peanuts, walnuts, or pecans, an ounce a day of nuts help fill you up. Nuts add texture and flavor to salads, side dishes, baked goods, cereals, and entrees. They taste great alone, too. Zied recommends putting together your own "100-calorie packs" of nuts for easy and portable snacks.

4.Kiwis are among the most nutritionally dense fruits, full of antioxidants, says Ward. "One large kiwi supplies your daily requirement for vitamin C," says Ward. "It is also a good source of potassium, fiber, and a decent source of vitamin A and vitamin E, which is one of the missing nutrients, and kiwi is one of the only fruits that provides it." The sweet taste and colorful appearance of kiwis makes it easy to slice in half, scoop out with a spoon and enjoy alone, or slice it into desserts, salads, or side dishes. Kiwifruit can also have a mild laxative effect due to their high fiber content.

5.Quinoa is now readily available in many supermarkets and is one of the best whole grains you can eat, according to Zied. "It is an ancient grain, easy to make, interesting, high in protein (8 grams in 1 cup cooked), fiber (5 grams per cup) and a naturally good source of iron," she says. Quinoa (pronounced keen-wa) also has plenty of zinc, vitamin E, and selenium to help control your weight and lower your risk for heart disease and diabetes, she says. Quinoa is as easy to prepare as rice and can be eaten alone or mixed with vegetables, nuts, or lean protein for a whole-grain medley. Try to make at least half your daily grain servings whole grains. In addition to quinoa, try barley, oats, buckwheat, whole wheat, wild rice, and millet.

6.Beans, beans, good for your heart -- really! Beans are loaded with insoluble fiber, which helps lower cholesterol, as well as soluble fiber, which fills you up and helps rid your body of waste. They're also a good, low-fat source of protein, carbohydrates, magnesium, and potassium. Bauer favors edamame (whole soybeans) because they also contain heart-healthy omega-3 fatty acids. Beans can easily substitute for meat or poultry as the centerpiece of a meal, says Bauer, but they also work as a side dish, or tossed into soups, stews, or egg dishes. The U.S. Dietary Guidelines recommend 3 cups weekly.

7.Salmon is a super food because of its omega-3 fatty acid content. Studies show that omega-3 fatty acids help protect heart health. That's why the American Heart Association recommends eating fatty fish like salmon twice weekly. Salmon is low in calories (200 for 3 ounces) has lots of protein, is a good source of iron, and is very low in saturated fat. You can simply grill or bake it, top it with salsas or other low-fat sauces, or serve it on top of salad greens. If you don't like salmon, Lichtenstein recommends eating other kinds of fish, like canned tuna. And what about the mercury content? (Mercury is known to accumulate in fish.) "The benefits of eating salmon or other fatty fish twice weekly far outweigh any risks, but if you are concerned, check with your doctor," says Zied.

8.Broccoli is one of America's favorite vegetables because it tastes good and is available all year long. It's a rich source of vitamin A, vitamin C, and bone-building vitamin K, and has plenty of fiber to fill you up and help control your weight. "Some people think beta-carotene (vitamin A) is only found in orange and yellow vegetables, but broccoli is an excellent source," says Ward. You can eat broccoli raw, lightly steamed, stir-fried, roasted, or grilled. Eat it as a side dish, or toss into grains, egg dishes, soups, and salads.

9.Sweet potatoes are a delicious member of the dark orange vegetable family, which lead the pack in vitamin A content. Substitute a baked sweet potato (also loaded with vitamin C, calcium, and potassium) for a baked white potato. And before you add butter or sugar, taste the sweetness that develops when a sweet potato is cooked -- and think of all the calories you can save over that loaded baked potato. "If we eat more foods like sweet potatoes that are rich sources of potassium, and fewer high-sodium foods, we can blunt the effect of sodium on blood pressure and reduce bone loss," says Zied. Other dark orange vegetable standouts include pumpkin, carrots, butternut squash, and orange bell peppers.

10.Berries pack an incredible amount of nutritional goodness into a small package. They're loaded with antioxidants, phytonutrients, low in calories, and high in water and fiber to help control blood sugar and keep you full longer. And their flavors satisfy sweets cravings for a fraction of the calories in baked goods. Blueberries lead the pack because they are among the best source of antioxidants and are widely available. Cranberries are also widely available fresh, frozen, or dried. All can add flavor and nutrition to numerous dishes, from salads and cereals to baked goods and yogurt.

My Thoughts: The ALCAT Test Surpasses All Other Allergy Testing

From: Laura Griffin - Atlanta, GA

It is my opinion and experience after years spent in and out of doctor's offices, even when I already knew I couldn't eat wheat and gluten, that the ALCAT test is superior to all other blood work testing.


This is the only test, and I had at least 30 done over more than a decade, that ever showed I was gluten intolerant. All the other tests came back showing I wasn't even the slightest bit intolerant to wheat, barley, rye, malt, or gluten in it's entirety.

The test is expensive, insurance will only cover a portion (in my case), but at a time when I was having other immune issues and allergic to a lot of other foods, ALCAT is in my opinion the true Gold Standard when it comes to testing through blood. Not only did it say I should avoid gluten (which I was absolutely already doing for many years) but it showed an off the chart intolerance. Whereas, all the other antibody testing remained always negative.

I was lucky that my doctor used this test routinely and knew enough to suggest it for me as I was not testing for gluten intolerance but for other things that were making me sick during that period of time. It pulled up a lot of foods for me to avoid for some time until my immune system was strong again.

The website contains a lot of very useful information and I encourage you to check it out through the link above @ www.alcat.com
