Effects of Supplementation of Murici (Byrsonima crassifolia) and Taperebá (Spondias mombin) Pulp Extracts on Food Intake, Body Parameters, and Oxidative Stress Markers in Healthy Rats.

This study evaluates the effects of supplementation of murici (Byrsonima crassifolia) and taperebá (Spondias mombin) pulp extracts on dietary intake, body composition, biochemical parameters, and markers of oxidative stress. Two experiments 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, taperebá group 50 mg/(kg⸱day) (50Tap), taperebá group 100 mg/(kg⸱day) (100Tap), and taperebá group 200 mg/(kg⸱day) (200Tap). Results showed lower feed intake in 50Mu, 100Mu, and 100Tap groups (13%, 12%, and 10%, respectively, P < .05) and lower body fat in 200Mu, 100Tap, and 200Tap groups (16.0%, 29.1%, and 27.1%, respectively, P < .05). Only the 100Tap group showed reduced adipose tissue content (30.4%; P < .05). Increased plasma antioxidant capacity was observed at all doses for both fruits. Taperebá 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 substances levels were reduced in all groups receiving taperebá (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 can contribute to health maintenance and disease prevention, through their effects on controlling food intake, improving body composition, and in combating oxidative stress.

Murici (Byrsonima crassifolia (L.) Kunth and verbascifolia (L.)) and Tapereba (Spondias mombin) Improve Hepatic and Inflammatory Biomarkers in High-Fat-Diet Rats.

The present study investigated the effects of murici and tapereba on improving hepatic and inflammatory biomarkers in high-fat-diet rats. Female Wistar rats were divided into five groups (n = 10/group): control (CON), high-fat diet (HF), murici drink + high-fat diet (Mu-HF), tapereba drink + high-fat diet (Tap-HF), and murici and tapereba blend drink + high-fat diet (MT-HF). Drinks were offered daily for 60 days, following which body and liver weights, hepatosomatic indexes, serum parameters, inflammatory profile, and antioxidant activity (DPPH and ORAC) were analyzed. The cell death of hepatic cells was evaluated using flow cytometry. It was observed that weight gain was similar among the groups, while glycemia was lower in the MT-HF group. A high-fat diet increased the concentration of cholesterol total, ALT, IL-1ß (in plasma and liver), and TNF-α (in the liver), and this was reduced by treatment with the fruit-based beverages. The other evaluated parameters showed no statistically significant difference. Compared to the CON and HF groups, the groups that received the drinks had higher cellular antioxidant activity and reduced oxidative stress, lipid oxidation, and development of pro-inflammatory cytokines, such as IL-1ß. A high-fat diet induced higher cell death in hepatic tissue, which was prevented by the murici, tapereba, and the fruit-blend drinks. The consumption of murici, tapereba, and fruit-blend-based beverages showed beneficial effects on liver metabolism; therefore, they may serve as a nutritional approach for preventing and treating non-alcoholic liver disease.
