Purpose
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.

Primary Outcome Measures:
- Inflammatory profile by interleukin-6 (IL6) concentration in plasma. [ Time Frame: six times per day (kinetic: T0 to T480) on three interventional days ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- Muscular strength, Body composition [ Time Frame: Once at the first and at the last visit ] [ Designated as safety issue: No ]
- Total plasma lipids (total cholesterol, HDL-Cholesterol, LDL-cholesterol, Triglycerides (TG), non-esterified fatty acid, Plasma hormonal profile, Plasma inflammatory profile, Markers of Endothelial function, Plasma lipopolysaccharide concentration. [ Time Frame: Six times per day (kinetic: T0 to T480), on three interventional days ] [ Designated as safety issue: No ]
- Pro-inflammatory cytokines expression in subcutaneous adipose tissue [ Time Frame: Twice per day (before the meal and 6 hours after), on three interventional days ] [ Designated as safety issue: No ]
- Urinary metabolomic profile [ Time Frame: Three times per days (T0,T240,T480), on three interventional days ] [ Designated as safety issue: No ]

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

Detailed Description:
32 healthy volunteers will be separated into four groups: 8 young lean men, 8 young obese men, 8 aged lean men and 8 aged obese men. They will come to the center four times after inclusion, with 2 to 4 weeks wash out each time. At the first visit they will undergo different test to evaluate their body composition, glucose tolerance, resting energy expenditure, and muscular strength. At the other three visits, people will undergo a kinetic blood sampling, urine and biopsies of adipose tissue over a period of 8h after ingestion of a test meal. The different meals tested (Oleic acid vs palmitic acid vs no lipid) will be given in a random way over the three visits. Before each of these three visits, a controlled diet will be established. At the last visit body composition and muscular strength will be evaluated.
