Whey Protein, How Much is Too Much?
Whey and Soy manufacturers did a superb job of confusing the public. For few years now the fitness and health community has been drinking up soy.
Then studies revealed that due to its fast gastric emptying properties most of the protein taken in via whey protein is metabolized and burned up in the liver. The whey manufacturers first responded by increasing the number of grams per serving. Why not? More protein would have to be consumed, thus more protein is sold.
Soy is popular with vegetarians. The Soy manufacturers looked on as whey protein sales sky rocketed, and, in to get their own piece of the pie, they went after the “health” market, primarily women. Many of the research studies the soy manufacturers cite are valid, but do not represent the entire picture.
In one particular study published in France, two groups of apparently healthy men were fed isocaloric diets with one group using soy protein, the other using animal products as a protein source. The goal was to see if there was a reduced propensity for gallstones if animal proteins are replaced by soy. Since gallstone accumulation can be linked with crystallization of cholesterol, at its conclusion the study examined cholesterol levels.
The study showed that cholesterol crystallization was slightly retarded in the soy group extrapolating that soy can aid in preventing gallstones. Here’s what the study neglected to address. There wasn’t any control over fruit and vegetable intake. Soy is a vegetable, and it does happen to fall into the group of veggies that are high in isoflavones.
Isoflavones have been closely linked to health benefits including a lowering of cholesterol. We’ve known for years that a predominance of animal meats can have adverse affects on cholesterol, but that doesn’t mean that someone consuming soy would have better cholesterol levels than someone eating combinations of chicken breast, turkey breast, fish, and egg whites and a variety of natural vegetables. You can see how the conclusions drawn from studies can be misconstrued and over-emphasized in significance.
While a great number of scientific studies can be held up to show the cancer resistive benefits of a diet rich in vegetable foods (soy included), we can not extrapolate from those studies that someone consuming soy instead of milk proteins, egg proteins, and lean animal proteins will exhibit better health, and if an exercise component is included, the conclusions in non-exercising individuals are almost invalidated.
Most of the research promoted about soy is publicized by companies with a financial stake in Soy Protein sales. The Soybean Board is a good example. Very often the elements of a sound study are taken out of context to boost sales of soy.
Metabolically, recent data suggest that you should consume a mixture of casein and whey protein for optimal results. Unless you are a vegetarian, you’ll see the best results from consuming a wide variety of foods as part of your nutrition program.
