The object of the study was to ascertain if a high carbohydrate intake is a risk factor for breast cancer. The diets of 475 women aged 20 - 75 with breast cancer were compared with 1,391 women without breast cancer.

The study found that compared with women that consumed the least carbohydrates, the women that consumed the most carbohydrates had a 122% increased risk of breast cancer. This was similar for both premenopausal and postmenopausal women.
