Meat had been called the “Perfect Protein” but we now know animal protein has high levels of IGF 1 which causes cancer. Dr Greger talks about IGF 1 in meat and soy. Soy was called the perfect non-meat protein because it resembled animal protein. Unfortunately it also has higher levels of IGF 1. If you swapped soy exclusively for meat you probably wouldn’t be lowering your cancer risk by that much. If you eat some soy (3-5 servings, see yesterdays BLOG) and ate other fruits, nuts and vegetables and no meat you would significantly reduce IGF 1 levels.

Dr. Greger says research shows eating too much soy can eliminate the benefits of a meat-less diet. Too much of anything is not good! What is too much? He recommends 3-5 servings a day as a healthy benefit. Watch his video at the above link. Not all fake meat products are made from soy!
