Abstract:
:Twelve type I (insulin-dependent) diabetic subjects in stable metabolic control for at least 3 mo received a controlled diet containing 50% carbohydrate, 35% fat, and 15% protein. Calorie intake varied from 1800 to 2200 calories, depending on individual needs. Part of the polyunsaturated omega-6 fatty acids (omega 6FAs) were isocalorically exchanged with omega 3FAs (2.7 g/day provided by fish oil concentrates) for 10 wk. Subject selection was based on the fact that the atherogenic index (total cholesterol/high-density lipoprotein cholesterol [HDL-chol]) remained greater than 5. Total cholesterol did not change, but HDL-chol (P less than .05) increased significantly, and the mean +/- SD atherogenic index decreased from 5.9 +/- 1.1 to 5.1 +/- 1.3. Plasma triglyceride levels also decreased (P less than .05). There was a small (approximately 2%) but significant (P less than .05) decrease of whole-blood viscosity at low shear rate because of a similarly small (approximately 2% decrease (P less than .05) of plasma viscosity. Erythrocyte viscosity values and the erythrocyte transit time, measured with the St. George's filtrometer, remained unchanged during fish oil intake. Four weeks after stopping the omega 3FA administration, the triglyceride level was again increased (P less than .05) and was even higher than the starting value (P less than .05). Plasma and whole-blood viscosity also increased to the starting levels, demonstrating that lipid alterations are accompanied with blood viscosity changes in the presence of a stable metabolic control.
