Butter differs from olive oil and sunflower oil in its effects on postprandial XXXX and @entity1674 -rich lipoproteins after single mixed meals in healthy young @entity1 .

Accumulation of postprandial @entity1674 -rich lipoproteins is generated by assimilation of ingested dietary fat and has been increasingly related to atherogenic risk. Nevertheless, the influence of different kinds of dietary @entity1718 on postprandial lipid metabolism is not well established, except for (n-3) polyunsaturated long-chain @entity1718 . Our goal was to evaluate the effects of test meals containing a common edible fat source of saturated (butter), monounsaturated (olive oil) or (n-6) polyunsaturated (sunflower oil) @entity1718 on postprandial lipid and @entity1674 -rich lipoprotein responses. After a 12-h fast, 10 healthy young @entity1 ingested mixed meals containing 0 g (control) or 40 g fat, provided as butter, olive oil or sunflower oil in a random order. Fasting and postmeal blood samples were collected for 7 h. The no-fat test meal did not elicit any change over baseline except for plasma phospholipids, insulin and nonesterified @entity1718 . Conversely, the three fat-containing meals elicited bell-shaped postprandial changes (P < 0.05) in serum @entity1674 , free and esterified @entity165 , and nonesterified @entity1718 . The butter meal induced a lower postprandial rise of @entity1674 in serum and chylomicrons (incremental AUC, mmol.h/L: 0.72) than the two unsaturated oils (olive oil: 1.6, sunflower oil: 1.8), which did not differ. Circulating chylomicrons were smaller after the butter meal than after the two vegetable oil meals. The in vitro susceptibility of circulating chylomicrons to hydrolysis by postheparin plasma was higher after sunflower oil than after butter or olive oil. We conclude that butter results in @entity407 and chylomicron accumulation in the circulation of young @entity1 than olive or sunflower oils after consumption of a single mixed meal.
