The science is clear: Insulin is carcinogenic.
People with insulin resistance, metabolic syndrome/pre-diabetes, and type 2 diabetes have high levels of blood insulin, typically many times higher than normal. People with these conditions are at increased risk for various cancers such as breast, colon, prostate, and pancreas (Gallagher 2015). Type 2 diabetics are also more likely to die of their cancer than non-diabetics. While the cause-effect connection is due to a number of factors (high blood sugar, inflammation, high circulating estrogen levels, increased insulin-like growth factors, etc.), much of the increased cancer risk is due to increased levels of insulin.
So what drug is commonly prescribed to people with type 2 diabetes who already have high insulin levels? More insulin. Injected insulin further raises blood insulin levels in people who start with high insulin levels. What would you predict would be the result? You got it: lots more cancer (Hemkens 2009; Suissa 2011). Risk appears to be greatest with the glargine form of insulin (e.g., Lantus, Toujeo).
What foods raise levels of blood insulin the most, triggering insulin resistance that, in turn, causes even higher levels of insulin? The amylopectin A of grains, sucrose (table sugar), and sugars containing plentiful fructose (agave, high-fructose corn syrup, honey, maple syrup). What foods are people with insulin resistance, pre-diabetes, and type 2 diabetes advised to eat by conventional dietary guidelines, including that of the American Diabetes Association? Yup: lots of grains, unrestricted sugars, and reduced fats.
Are you beginning to appreciate the depth of ignorance (or deception) that operates in conventional thinking? Start with flawed dietary advice that causes high blood sugar followed by high blood insulin. Over time, insulin resistance develops, worsened by inflammation, visceral fat growth, and hormonal distortions (e.g., high estrogen, low testosterone). Blood sugars rise and John Q. Primary Care steps in to prescribe insulin.
How to reverse the entire high-insulin mess? Reverse the factors that raise blood sugar, insulin, and insulin resistance. What was the first “domino”? Grains, sugars, and fructose-containing sweeteners. It’s really incredibly simple. This is why people with type 2 diabetes who follow the Wheat Belly path of eliminating all grains, restricting net carb exposure to 15 grams or less per meal, and avoid fructose-rich sweeteners are typically NON-diabetic over several weeks to months (delayed due to the transient insulin resistance generated by weight loss and the fatty acids that flood the bloodstream during mobilization of fat stores).
You may also begin to appreciate that the healthcare system causes pre-diabetes and type 2 diabetes, then profits from its “treatment,” failing to provide consumers with a common sense, logical, and scientific solution that has been obvious all along.
