Lower Risk of Breast Cancer with DASH
A diet designed to lower blood pressure may also decrease the risk of one type of breast cancer, suggests a new study published in the American Journal of Epidemiology.
The study is from the long-running Nurses Health Study.
The study categorized how closely almost 87,000 cancer-free women followed a diet known as DASH (Dietary Approaches to Stop Hypertension). DASH emphasizes fruits, vegetables, nuts, legumes, and whole grains; it limits sodium, sugary foods, and red meat.
After tracking the women for 26 years, slightly less than one percent of the women developed ER-negative breast cancer. But the women whose diets most closely resembled the DASH diet had a lower risk of developing estrogen receptor-negative (ER-) breast cancer, compared to the women who least followed the diet. ER- cancers, which do not respond to the hormone estrogen, account for about one-quarter of breast cancers.
No association was found between estrogen receptor positive breast tumors and fruit and vegetable intakes.
