Insulin Like Growth Factor (IGF1) is a cancer promoting hormone found in animal protein. This appears to be why vegan diets seem to drastically and quickly cancel the negative affects of cancer. This hormone causes inflammation that takes hours for our body to fight. What do most Americans do hours after they have eaten? They eat again and usually eat something with animal protein (meat, poultry, eggs, milk, cheese, butter). The more we eat of this type of protein, the more IGF1 our bodies need to fight. inflammation is a major link to all types of cancer. I have spoken about this before on this BLOG. Dr Greger talks a lot about it in his BLOGs. Here are some links to his BLOGs:


Eat your veggies and fight the affects of this hormone or simply don’t eat animal protein.


Animal vs. Plant Protein

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.

The Perfect Protein

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.

Ignore your Veggies and Live with Cancer

Yesterday Dr. Greger spoke about IGF1 and IGF1 Binding protein. Today he speaks about measuring these two substances in our blood. What they found is that eating lower levels of plant based diet allows IGF1 (Insulin-Like Growth Factor) to increase in our bodies. Higher levels of IGF1 relate directly to cancer growth. The body tries to flush out this IGF1 by using a protein called IGF1 Binding protein. At high IGF1 levels, there is only so much our body can do. Changing your diet to more of a plant based diet, causes IGF1 levels to drastically lower. This eliminates the chance of cancer drastically. Your choice! Eat your veggies and fight cancer or ignore your veggies and live with cancer.
