Abstract
A feasibility study was instituted to determine if women with postmenopausal breast cancer would follow a low‐fat diet (20% of kcal) for at least four months. Nineteen women, whose baseline food intake was 1,504 ± 420 kcal with 56 ± 16 g of fat, reported a decrease in fat intake to 21 ± 6 g after two months of dietary intervention. Serum concentrations of cholesterol, HDL cholesterol, and estradiol were significantly reduced by the fifth month on the diet. We conclude that self‐selected patients can adhere to a low‐fat diet, and that serum cholesterol may serve as an indicator of dietary compliance.
