Proteins in food are the most common allergy causing components. Protein allergies occur when the body's immune system identifies a protein as harmful. Some proteins or fragments of proteins are resistant to digestion and those that are not broken down in the digestive process are tagged. This tagged protein is viewed by the immune system as harmful. The immune system, thinking the body is under attack, triggers an allergic reaction.

Why an increase in food allergies?

The world today is focused on eating a diet high in protein. In addition, there is an ever increasing promotion of high protein diet plans for weight loss. This, I think, is causing an increase in allergies and various diseases that are associated with a high amount of protein consumption.

Since protein is the main cause of allergies, it's obvious that highly concentrated protein foods like whey protein concentrate or isolate, texturized vegetable protein (TVP), engineered sandwich meats and cheese would be harmful. The negative reaction by the body is understandable because of the concentration of protein, coupled with the reality that these "designer" foods are not identifiable to the body.

We were created to consume high volumes of fruits and other foods in their whole state as this is most beneficial to our bodies. This is why many people who are allergic to soy protein concentrates are not allergic to the whole soy bean.
