Growth hormone

Studies have been done comparing high protein eaters with lower protein eaters and no significant difference in IGF 1 levels were detected. But when they broke out the types of protein, animal vs. plant, they found animal protein raised IGF 1 levels while plant protein lowered the levels. Dr Greger says getting high levels of IGF 1 tells our livers to start building. Unfortunately tumors are the result. We don’t really want excessive growth (as adults). We want to maintain our growth. Eating meat will increase these growth hormones and eating plants will decrease the levels. Choose wisely.
