Randomized Controlled Trial Clinical Trial
Effect of meal fat quality on oxidation resistance of postprandial VLDL and LDL particles and plasma triacylglycerol level.
This study was performed to examine the postprandial effects of meals containing dietary fats, with their natural fatty acid composition and tocopherol content, on the plasma triacylglycerols (TG) and tocopherols and on the resistance of VLDL and LDL to oxidation. On six separate days eighteen healthy male subjects were given low-fat meals (LF) or the LF meals enriched with sunflower oil (SO), rapeseed oil (RO), olive oil (OO), palm oil (PO), or butter (B) in a crossover design. The fat-rich meals all resulted in similar postprandial TG responses while the LF test meal did not increase plasma TG level. ⋯ The gamma-tocopherol content of VLDL was highest after RO-meal as compared with all other test meals (P = 0.0019), and higher after SO as compared with B (P = 0.0148). Large individual differences were noted. In conclusion, meals enriched with different fats lead to the formation of VLDL particles with varying resistance to oxidation.

The main purpose of treating diabetes is to prevent chronic complications. Strict glycemic control is known to suppress the occurrence and progression of these complications. The test for plasma glucose is essential to identify diabetic patients, as mild hyperglycemia without symptoms can be a risk factor for complications. ⋯ ADA recommends the use of FPG alone for the diagnosis of diabetes, but findings from both Japan and Europe indicate that many diabetic subjects would be classified as non-diabetic solely on the FPG test. JDS recommends the use of the glucose tolerance test when the elevation of FPG is mild. Keeping glycemia near-normal by periodic monitoring of glycemic parameters and by appropriate treatment would prevent or reduce the diabetic complications in patients to a minimum.
