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.

Placebo Comparator: mashed potatoes
Mashed potatoes is composed of potatoes and Skim milk powder.
Other: Mashed potatoes
Mashed potatoes: Potatoes + Skim milk powder
Experimental: Mashed potatoes + Oleic Acid
The test meal is mashed potatoes with 1g/Kg of weight of lipids with 75% of Oleic Acid
Other: Mashed potatoes + Oleic acid
Mashed potatoes with 1g/Kg of weight, of lipids with 75% of Oleic Acid
Experimental: Mashed potatoes + Palmitic Acid
The test meal is mashed potatoes with 1g/Kg of weight of lipids with 39% of saturated fat with 32% of palmitic acid.
Other: mashed potatoes + Palmitic acid
Mashed potatoes with 1g/Kg of weight, of lipids with 32% of palmitic acid
