The objective of this study was to compare the effects on eating behavior, lipids, lipoproteins, lipid peroxidation, and glycemic control in women with type 2 diabetes of a high-monounsaturated fat diet (HM) compared to a high-carbohydrate diet (HC). In an outpatient feeding study, ten hypertriglyceridemic postmenopausal type 2 diabetic women alternately for six weeks consumed the HM and HC diets. On the HM diet, 45% of total calories were consumed as carbohydrate and 40% as fat (27% monounsaturated) compared to 55% carbohydrate and 30% fat (10% monounsaturated) in the HC diet. At the beginning and end of each diet phase, total lipids, lipoproteins, lipid peroxidation, and glycemic variables were measured. For 8 days in each diet phase eating pattern frequency, palatability of foods, hunger and fullness were assessed. At the end of each diet phase, taste testing to determine preference for fat was conducted. Total cholesterol was significantly decreased on the HC diet. Serum triglyceride, very low density lipoprotein (VLDL) triglyceride and cholesterol, and apolipoproteins A-1 and B were not significantly different on the two diets. When comparing initial to final values, both diets lowered LDL-C; however, the change was greater on the HM diet. Lipid peroxidation variables improved when the HM diet was consumed. Glycemic variables improved on both diets. No significant differences between total number of eating episodes on the HM and HC diet phases were found. Both diets were rated as highly palatable. Hunger and fullness ratings varied within and between subjects. However, fullness was more commonly experienced than hunger on both HM and the HC diet. Preference for fat was not found at the end ofHM or HC diets. However, subjects differed significantly in ratings for liking of foods that were salty, sour, and bitter when compared to nondiabetic women. Consumption of the HM and HC diets did not result in deterioration of lipid status. The HM diet by virtue of less oxidation of the LDL particle and improvement of glycemic control provides an important advantage over the HC diet. A description of eating behavior of women with type 2 diabetes emerged. === Graduation date: 2000
