Sugar and Cancer: Is There a Link?

by Kelley Herring on December 6, 2012

Did you know the food you eat impacts your body’s production and function of hormones, inflammatory substances and immune factors that play an important role in cancer? It’s true!

In fact, one of the most important elements in preventing cancer is keeping your blood sugar stable.

That’s because high-glycemic foods fuel cancer’s fire by elevating insulin and cancer-promoting growth factors.

Sugar and Cancer: More Sweets, More Risk

Numerous studies have found high glycemic diets are associated with the most common cancers. Let’s take a look:

  • In the Women’s Health Study of 39,876 women followed for 8 years, positive associations were found between dietary glycemic load (GL) and overall glycemic index (GI) and risk of colorectal cancer in women.
  • Investigators from the Harvard School of Public Health, the Karolinska Institute of Stockholm and University of Athens studied 150 Greek men to evaluate the role of hormones involved in prostate disease. The study found that men with higher levels of IGF-1 had a higher risk of developing prostate cancer.
  • A recent study involving over 2,500 Italian men bolstered the evidence for the role of IGF and prostate cancer, showing a direct relationship between dietary GI and GL and prostate cancer risk.
  • Using a retrospective food frequency questionnaire, the Nurses’ Healthy Study II interviewed 47,355 women and found that a higher dietary glycemic index during adolescence was associated with an increased risk of breast cancer.

Reduce Sugar For a Longer, Healthier Life

To help guard against cancer, keep your blood sugar in check by basing your diet on the grain-free, low-carb principles our Paleo ancestors enjoyed.

And beware of natural sources of sugar like fruit that are touted as healthy – to your body, sugar is sugar!
