BACKGROUND:Postprandial hypertriglyceridaemia is common in diabetes. Fatty acids are regulators of gene expression and may play an important role in regulatingthe postprandial lipoprotein cascade. AIM: To examine postprandial lipoprotein differences between diabetic and control subjects on polyunsaturated (linoleic) and monounsaturated (oleic) fat diets. METHODS: A randomised, crossover study. RESULTS:LDL was greater and HDL less (p < 0.05) in diabetic patients compared to controls on the linoleic acid diet. Apo E per particle was significantly lower in the diabetic patients compared to control subjects on both linoleic (p < 0.05) and oleic acid diets (p < 0.01). HDL apo E was also significantly lower in the diabetic patients compared to controls on the linoleic acid diet (p < 0.02). CONCLUSION: A change from linoleic to oleic acid diet resulted in an improvement in LDL and HDL in the diabetic patients. We suggest that the reduced apo E/particle in the diabetic patients may be an explanation for the delayed lipoprotein clearance.
