This study evaluates the effects of supplementation of murici (Byrsonima crassifolia) and tapereba´ (Spondiasmombin) pulp extracts on dietary intake, body composition, biochemical parameters, and markers of oxidative stress. Twoexperiments were conducted with a total of 80 healthy male Wistar rats and a 30-day supplementation. In the first experiment,animals were divided into control (C) group, murici group 50 mg/(kg$day) (50Mu), murici group 100 mg/(kg$day) (100Mu),and murici group 200 mg/(kg$day) (200Mu). In the second experiment, animals were divided into C group, tapereba´ group50 mg/(kg$day) (50Tap), tapereba´ group 100 mg/(kg$day) (100Tap), and tapereba´ group 200 mg/(kg$day) (200Tap). Resultsshowed lower feed intake in 50Mu, 100Mu, and 100Tap groups (13%, 12%, and 10%, respectively, P < .05) and lower bodyfat in 200Mu, 100Tap, and 200Tap groups (16.0%, 29.1%, and 27.1%, respectively, P < .05). Only the 100Tap group showedreduced adipose tissue content (30.4%; P < .05). Increased plasma antioxidant capacity was observed at all doses for bothfruits. Tapereba´ supplementation reduced ferrous oxidation–xylenol orange levels (50Tap: 8.4%, 100Tap: 16.1%, 200Tap:24.3%; P < .05) and increased thiol levels (50Tap: 39%, 100Tap: 31%; P < .05). Serum thiobarbituric acid reactive substanceslevels were reduced in all groups receiving tapereba´ (50Tap: 77.7%, 100Tap: 73.1%, 200Tap: 73.8%; P < .05) and murici(50Mu: 44.5%, 100Mu: 34%, 200Mu: 43%; P < .05). Therefore, it is suggested that the inclusion of these fruits in the diet cancontribute to health maintenance and disease prevention, through their effects on controlling food intake, improving bodycomposition, and in combating oxidative stress.
