The research is clear: In a study of more than 6,000 people, those who had diets high in protein were at as high of a cancer risk as smokers. They also had higher incidences in diabetes, linking animal protein to insulin levels. There was an especially strong link in men with animal protein and lung and colorectal cancers.
What is "animal protein"? It is red meat, poultry, eggs, dairy, cheese, fish, seafood, pork, lamb, farm-raised, pasture-raised, grass-fed, organic, non-GMO.... if it comes from an animal, it is animal protein.
What about plants? The same risks were not found with plant-based protein sources like beans, lentils, peas, grains, nuts, and seeds.
So what is "high protein"? It's got to be one of those body-builder-type diets, right?
"High protein" refers to more than 20% of your daily calories.
For a (1600 calorie/day) woman, this is about 32g/day.
For a (2000 calorie/day) man, this is about 40g/day
One cup of diced, roasted chicken breast has 42g of protein. Half a chicken breast has about 30g.
CDC's current recommendations are less than 45g/ protein a day for women and 56/g for men.
Who's the culprit? The culprit goes by IGF-1, a protein-controlled growth hormone. Remember in biology, you learned that proteins are made up of amino acids, the building blocks for cells.
Yes, they build muscles cells.
But they also build cancer cells.
But that sort of sounds like 1 cigarette/day for women and 2/day for men. Choose your risk.
