According to a study published in the Archives of Internal Medicine, consuming carbohydrates with high glycemic index (GI) such as white bread, sweets and sugary cereals appears to be associated with the risk of coronary heart disease in women but not men. However, not all carbohydrates have the same effect on blood glucose levels.
Italian researchers studied 47,749 adult men and women who completed dietary questinnaires. They found that women who consumed the most carbohydrates overall had approximately twice the risk of heart disease as those consumed the least. Women whose diet had the highest glycemic load had 2.24 times the risk of heart disease than those with the lowest glycemic load.
The researchers concluded "we tentatively suggest that the adverse effects of a high GI diet in women are medicated by sex-related differences in lipoprotein and glocuse metabolism" and that further studies are needed to verify the link between high-glucose foods and cardiovascular disease in men.
