Q: I am confused about the benefits of soy in the diet. I have read comments from several doctors claiming that soy as a source of protein in the diet (especially in place of animal protein) is a no-no. What are your thoughts?
A: You're right, it can be hard to know what to believe with so much conflicting nutritional information out there. We used to think that soy was not a complete protein, but as testing methods have improved, we now know better.
Currently, the Food and Drug Administration (FDA) has approved the use of a food claim for soy products which states that 25 grams of soy protein per day as part of a diet low in saturated fat will help lower blood cholesterol.
Many well-conducted research studies back-up this claim. And a new tool that measures protein quality -- specifically amino acid quality -- finds that soy is equal to animal protein. In fact, schools are now allowed to use soy as a one-to-one replacement for animal protein.
Bottom line? If youre looking for a high-quality meat protein alternative, consider soy your best friend.
