Effects of Diets High in Palmitoleic Acid on Serum Lipid Levels and Metabolism
Abstract
Using a controlled, crossover design feeding study, each of 30 healthy individuals (15 males and 15 females) aged 18 to 53 years, were fed, in random order, a tree nut based mono-unsaturated fat diet (MONO) (37% Kcal fat); an American Heart Association Step 1 diet (AHA) (30% Kcal fat); and a high saturated fat 'typical American' diet (AMERICAN) (37% Kcal fat). Mean and (standard deviation) for total Cholesterol at the end of the AMERICAN was 201.2 mg/dl (30.4). That for the AHA and the MONO diets was 193.1 (34.5) and 191.3 (32.6) mg/dl. HDL was 55.3 (7.6), 52.0 (8.2) and 52.8 (8.2). Triglycerides were 77.5 (32.7), 83.6 (32.6) and 70.4 (26.0). In all cases the values after AHA and MONO diets had similar positive effects on lipids when compared to an AMERICAN diet. In an absorption study involving 6 males, the dietary fats in a nut oil based diet, as reflected by the rise in serum triglycerides, were more available than those using ground or whole nuts. None of the diets had a glycemic effect. These results suggest that high monounsaturated fat diets which incorporate nuts could be part of a healthy energy diet for combat troops.
