Carbs and Heart Disease: New News for Women
Glycemic loads for whole grains and whole grain products are generally lower than those for white flour products
A new study published in the Archives of Internal Medicine found that eating lots of high-glycemic-index foods puts women at higher risk of developing heart disease. The glycemic index is an indicator of how high the carbohydrate portion of a food causes blood sugar (glucose) to rise. The index was developed to help people with diabetes better manage their blood glucose levels. Poor blood sugar control is now recognized as a risk factor for heart disease, even in people without the disease.
Carbohydrates and heart disease
Researchers in Italy followed more than 47,000 people for an average of almost eight years. Diet questionnaires completed at the beginning of the study assessed the amount of carbohydrates and high-glycemic-index and low-glycemic-index foods in the participants' diets, and their overall dietary glycemic load (another measure of the effects of diet on blood sugar levels). The researchers noted the following:
Not all carbs are created equal
While these findings show that a high-carbohydrate diet can put women at risk for heart disease, it is important to note that complex, low-glycemic-index carbohydrates are not the culprits.
"Our finding that only carbohydrates from high-glycemic-index foods increased cardiac risk suggests that the quality of the carbohydrates is more important than the amount when it comes to preventing heart disease," said study co-author Dr. Vittorio Krogh of the Fondazione IRCCS Istituto Nazionale dei Tumori in Milan, Italy.
Reducing your glycemic load
Keeping in mind that high-calorie, high-carbohydrate foods with high-glycemic-index values raise the dietary glycemic load and increase women's heart disease risk, here are some tips to help women choose heart-healthy carbohydrates:
