Hyperinsulinemia - Risk for Breast Cancer?

Hyperinsulinemia is defined as an abnormally high level of blood insulin. This is commonly caused by some degree of insulin resistance which is often seen in individuals with higher than normal levels of body fat. However, hyperinsulinemia can be seen in non-obese individuals even though it is rare. An analysis of 1651 women enrolled in the Women's Health Initiative Observational Study, conducted by researchers at Albert Einstein School of Medicine, found that elevated blood insulin levels were associated with increased risk of breast cancer. Previous studies did not isolate women using HRT and those who were not as well as those who had higher blood estrogen levels, a known risk factor for breast cancer.

So what does this mean for all of us regardless of BMI (body mass index)? Even though high BMI is a known risk factor for breast cancer, it means that following a healthy diet to control blood sugar levels is critical for all individuals. Avoiding refined carbohydrates and sugar is important in preventing blood sugar spikes and consequent elevations in insulin levels. In addition, balancing the macronutrients of protein, fat and carbohydrates regardless of refinement, is key for each meal consumed. At each meal the carbohydrate consumption should be limited to 15 to 20 grams and protein, fat and fiber (component of plant foods), should be in relative balance so that blood sugar levels are maintained at an even keel. This principle applies to breakfast, lunch, dinner and snacks for the best possible outcome. Always start with whole foods whether it be fruits, vegetables, grains or the infrequent meat product. Monitor the grain intake at 15 to 20 grams of CHO and add moderate amounts of fat and protein. Be more liberal with the fiber as it is powerful in helping slow the rate of sugar absorption and is essentially calorie-free. After cooking this way for awhile, you will become use to the process. You will wonder how you ever managed before with the energy you've gained from eating more balanced.
