OBJECTIVE: The objective of the present study was to verify the effect of a dietary oil, consisting mainly of diacylglycerol (DAG) oil, in a typical meal on postprandial changes in serum triacylglycerol (TAG) and remnant-like particle cholesterol (RLP-C) compared with dietary triacylglycerol (TAG) oil. METHODS: In a double-blind, randomized, crossover design, 43 healthy Japanese men and women ingested test meals (2093 kJ of energy, 30 g of protein, 19 g of lipids, and 51 g of carbohydrates) containing 10 g ofDAG oil (DAG meal) or TAG oil (TAG meal). Blood samples were collected in a fasting state (0 h) and at 2, 3, 4, and 6 h after ingestion of the meal. RESULTS:Postprandial TAG, RLP-C, and chylomicron TAG concentrations were significantly lower after the DAG meal compared with the TAG meal. In 29 subjects with fasting serum TAG levels of at least 1.13 mmol/L (100 mg/dL), differences in postprandial serum changes between meal types were even more remarkable and the incremental areas under the response curve (0 to 6 h) for serum TAG and RLP-C concentrations after the DAG meal were significantly smaller than those after the TAG meal. CONCLUSIONS: These results suggest that DAG oil in the daily diet is useful for the prevention of postprandial hyperlipidemia and related disorders.
