Can diets resulting in high insulin lead to greater breast cancer risk

The concern surrounding high insulin-producing diets is pretty well established when it comes to things like diabetes prevention and weight-related issues.

But is there a link between diets that produce too much insulin and breast cancer as well?

Let’s see.

Researchers set out to determine whether or not they could find an association between the insulin-producing potential of a diet and the incidence of invasive breast cancer.

To do so, they prospectively followed approximately 170,000 women who participated in the Nurses’ Health Study (parts I and II) and assessed their diets via food questionnaire every four years. The insulinemic (capacity to produce insulin) potential of their diets was scored using the food-based empirical dietary index for hyperinsulinemia (EDIH) and then analyzed to determine if there was any association between the EDIH scores and incidences of invasive breast cancer within the group of subjects.

Their results, published in the December 2022 edition of The American Journal of Clinical Nutrition, showed an association between those with the highest EDIH scores, or the most insulin-producing potential, compared to those diets with the lowest EDIH scores, or the least insulin-producing potential.

The researchers noted in their conclusion “…our findings suggest that dietary modifications to reduce insulinemic potential may reduce the risk of breast cancer.”

It is not as though we needed much more evidence to reduce added dietary sugar in our lives, but perhaps this should cause us to think a bit more about how many other insulin-producing carbs we are consuming.

Of course, this article is for informational purposes only and any decisions regarding treatment, prevention, or dietary plans should be discussed with your licensed healthcare professional to determine what is best and safest for you. It is possible that a reduction in carbs from where you are at right now might not be useful or could even be unsafe, so always discuss with your licensed healthcare practitioner first.
