Jordan Metzl, MD, sports medicine physician at New York City's Hospital for Special Surgery, and author of The Exercise Cure says athletes Should Never Eat The Following!
Anything With High-Fructose Corn Syrup, you can get a sugar crash. Pre-Workout Dairy and Fried Foods, they take a long time to digest. Sports Nutrition Drinks, Gels, and Bars,they are high in sugars. Non-Fat Yogurt, lactose breaks down into sugars. Avoid It: Cereal,the serving size that fits in most bowls, you could be eating the equivalent of 4 to 5 slices of white bread. Whey Protein and Other Animal-Based Protein Powders, whey protein isolate, for example, is highly acid forming I personally suggest to use the isolate but to use concentrate!
Whey protein concentrate, NOT protein isolates
Protein isolates are proteins stripped away from their nutritional cofactors. There are three
problems with that...
• All isolates are exposed to acid processing.
• Your body cannot assimilate proteins in isolated form.
• Due to over-processing, isolates are deficient in key amino acids and nutritional
Sweetened naturally, NOT artificially, and low carb
Most whey products are artificially sweetened making them useless if you have sugar
sensitivities, or just don't want to put artificial sweeteners or flavors into your body.
Your whey should be low glycemic, low carb and should not contain any artificial sweeteners,
sugar alcohol, glycerin, fructose, sugar or gluten.
Maximum biological value, NOT compromised or damaged
Most whey proteins provide some benefit. But, due to the ingredients, the source of the whey,
the concentration of beneficial nutrients, or the type of processing, many whey products simply
don't deliver what they promise.
You want whey that's guaranteed to retain its maximum biological value -- one with all the key
amino acids, cofactors and beneficial micronutrients present and intact rather than compromised
or damaged, and not missing any amino acids or essential nutrients.
Easy to Digest, NOT Causing Digestive Stress
Many whey products contain long-chain fatty acids which are hard to digest and require bile
acids to absorb.
You want a whey protein powder with medium chain triglycerides (MCT). These are easily
absorbed, digested quickly, and utilized as energy without causing digestive stress.
Ideally, you want a product in which the MCT come from the best source of all -- coconut oil.
Free from Toxic Heavy Metals or at Such Low Levels NOT to be a Health Risk
Many protein powders both whey and non-whey could contain dangerous levels of heavy
metals like mercury, lead, cadmium, and arsenic.
A recent Consumer Reports' evaluation showed some leading brands of protein powders
exceeded United States Pharmacopoeia's (USP) recommended safety limits for certain
You want to avoid these products at all costs because any high concentration of heavy
metals taken over time could lead to serious health consequences.
Refined, Processed Complex Carbs, "What complex carbohydrates make up for in sustained energy release, they lose in digestibility and efficient transfer from food into energy," he explains. "In addition, refined, processed complex carbohydrates, such as those found in regular pasta and white bread, cause inflammation." Having an exceptionally low pH, and therefore a significantly acid-forming attribute, refined foods will promote inflammation and therefore reduce performance by hampering efficiency.
