The objective of the study was to evaluate the relationship of the amount and type of carbohydrates with risk of heart disease. 75,521 women aged 38-63 y with no previous diagnosis of diabetes or cardiovascular diseases were followed for 10 years. (729,472 person-years)
The study found that:
(a) The women who consumed foods with the highest glycemic load had a 98% increased risk of heart disease.
(b) Women who consumed foods with the highest carbohydrate content had a 23% increased risk of heart disease.
(c) Women with high dietary glycemic loads consumed more carbohydrates, dietary fiber and cereal fiber, but had lower intakes of fats, cholesterol and proteins, than did women with low glycemic loads.
(d) The 2 most important contributors to dietary glycemic load in this population were mashed or baked potatoes and cold breakfast cereals.
Foods with a high glycemic load include:
cornflakes
coco pops
special K
grape nuts
bagels
dried dates
rice
buckwheat
macaroni
spaghetti
potatoes
To conclude: Diets high in carbohydrates which have a high glycemic load, are associated with a 98% increase in heart disease.
