It's like eating the same great food but with a healthier, low-fat twist. To give you an idea, look no further than the traditional foods served in school cafeterias. You can also find soy-enhanced cheeses and lunch meats, not to mention soynut butter. Soybeans are equal to protein found in meat and milk, in both protein content and quality. No, it shouldn't.
Soy contains phytates which have been known to inhibit iron absorption.
However, many foods contain iron absorption enhancers. In fact, iron absorption can be further increased by vitamin C, common in tomato-based sauces traditionally used with lasagna, meatballs or pasta. Iron absorption varies from person to person based on an individual's iron status. Thus, iron absorption and nutrition are affected by the nutrients of the total diet, and is not a function of an individual food. Food allergy is a reaction of the body's immune system to certain proteins in foods.
