High-carb diet tied to cancer risk
NEW YORK - Reuters
High-carb diets put older women at risk of breast cancer, a study says.
Older women who eat a lot of starchy and sweet carbohydrates may be at increased risk of a less common but deadlier form of breast cancer, according to a European study. The findings from a study of nearly 335,000 European women, published in the American Journal of Clinical Nutrition, do not prove that sweets, French fries and white bread contribute to breast cancer - but they do hint at a potential factor in a little understood form of breast cancer.
Specifically, the study found a link between high “glycemic load” and breast cancers that lack receptors for the female sex hormone estrogen, so-called “ER-negative” breast cancers.
A high glycemic load essentially means a diet heavy in foods that cause a rapid spike in blood sugar, such as processed foods made from white flour, potatoes and sweets.
The study, conducted by Isabelle Romieu of the International Agency for Research on Cancer in Lyon, France, looked at nearly 335,000 women who took part in a long-running European study on nutrition factors and cancer risk.
