Postprandial Inflammatory Response in Healthy Men: Effect of Dietary Fat Source, Obesity and Age
The nature of dietary lipids, age and perivisceral adiposity could alter the postprandial inflammatory response. It is supposed that there is a relationship between the postprandial inflammatory response and the repartition of fat and lean mass, which could partially explain the muscle mass loss with age.
The aim of this study is to compare the inflammatory response of a normal meal or high fat meal (from different fatty acids sources) between young lean and young obese and aged lean and aged obese men.
