This studies’ results clearly support the idea that insulin resistance (insulin elevation) is highly correlated with cancer. In a study like this, one cannot say that insulin causes cancer but overall the evidence is pointing in that direction.
A quadrupling of the risk is a real association. We are not talking a 20% increase but rather a 400% increase which represents a definitive association. Diabetes, metabolic syndrome, and elevated cholesterol are all caused by insulin resistance. This type of evidence paired with the findings of Weston Price in the 1930s, where there was zero cancer in societies that were eating a stone age (low-carb, high-fat) diet, tells us that cancer is caused by carbohydrates and the resulting chronic insulin elevations.
Insulin is a growth-promoting hormone and it has been long known in gynecology that uterine cancer is much more common in the insulin-resistant Polycystic ovarian syndrome patient and in diabetics. I firmly believe that without carbohydrates in our food supply we would have very little if any cancer! Just another reason to pursue a low carb high-fat nutritional approach (ketogenic).
