| Outline of Final Research Achievements |
In this study, it has been tried to elucidate a relationship between postprandial lipidemia and intestinal inflammation induced by high-fat-diet (HFD) feeding. HFD-feeding for 1 week ameliorated postprandial lipidemia in the comparison to normal diet (ND) feeding in mice. Interestingly, saturated fatty acids induced the amelioration of postprandial lipidemia, but unsaturated fatty acids did not. These findings indicate that the feeding of HFD, particularly saturated fatty acids, ameliorates postprandial lipimide, suggesting increase in a risk of cardiovascular disease developments.
In addition, using a novel screening system for anti-inflammatory food factors, a novel food factor suppressing LPS-induced inflammation was identified: Food factor X. This compound improved the HFD-induced amelioration of postprandial lipidemia in mice.
