MethylGlyoxal (MG) is a glycation end product found in patients with diabetes, a Chronic Adult Disease (CAD). Another CAD is HyperCholesterolemia (HC). A classic animal model to study effects of HC is rabbit fed with high fat diets (HCR). Also HC can be reverse by the addition of Olive Oil (OO) to diets. The purpose of this study was to determinate MG variations under high fat and OO intake. To generate HCR, rabbits were fed with balanced diet supplemented with grease. After 6 months, fat was reduced and replaced by OO (1:1, fat:OO). Blood samples were analyzed by several biochemical parameters. In HCR, cholesterolemiaincreased three fold (87 ± 12 mg/dl) over control (25 ± 4 mg/dl, p < 0,001). The addition of OO to diet promoted a cholesterol lowering (48 ± 5 mg/dl). Curiously, triglyceridemia and glycemia showed a non-significant increment. MG blood levels increased in HCR (∆=385 µg/dl compared to NCR ∆=96 µg/dl; ∆ = differences between 6 months of treatment and 0 month) and decreased in OO rabbits (∆=-485 µg/dl). MG normally linked to glycemia could be also related to cholesterolemia. OO may benefit the HCR group by preventing the formation of MG
