RESUMO As principais causas de mortalidade estão relacionadas com doenças degenerativas crônicas não transmissíveis. O baru Dipteryx alata Vogel, é um fruto do cerrado brasileiro e destaca-se por sua composição antioxidante e nutricional. Este trabalho teve como objetivo avaliar a composição físico-química e a presença de compostos bioativos em sementes brutas e torradas de baru e, avaliar seus efeitos sobre o perfil metabólico, antropométrico e comportamental de ratos Wistar. As sementes de baru cruas e torradas a 90ºC por 30 min foram utilizadas para avaliar vitamina C, carotenóides, clorofila, capacidade antioxidante, concentração fenólica total, antocianinas e flavonóides. Os resultados da avaliação dos parâmetros acima não mostraram diferenças significativas entre as amêndoas brutas e torradas. Esse achado é importante porque as sementes de baru podem ser usadas em uma infinidade de produtos industriais sem perder propriedades de saúde fornecidas por antioxidantes como vitamina C, antocianinas, carotenóides, flavonóides e clorofila. No perfil metabólico de ratos Wistar os animais foram divididos aleatoriamente em 4 grupos (n = 10): G1 (grupo controle) e G2 (tratados com baru 20%); G3 (tratado com baru 30%) e G4 (tratado com baru 40%). Após 40 dias, os animais foram eutanaziados e os perfis metabólicos foram analisados (glicemia, colesterol, triglicerídeos, HDL-c, VLDL, LDL-c, proteína C reativa (PCR as), AST, ALT, índice de Lee, peso e gordura visceral). O uso de amêndoas de baru foi eficaz na redução de triglicerídeos, VLDL-c, LDL-c e aumento de HDL-c, e interferiu na porcentagem de ganho de peso, gordura visceral. Os resultados encontrados mostram que o uso de baru pode melhorar o perfil lipídico de ratos Wistar e podemos sugerir que o consumo dessas amêndoas ou produtos preparados com eles pode ser uma opção efetiva para a ingestão de produtos saudáveis. Na avaliação e comportamental de ratos Wistar, os resultados demostraram que a amêndoa de baru reduz a ingestão de alimentos e pode ajudar a prevenir o aumento do peso corporal e deposição de gordura visceral, bem como pode ajudar na redução do comportamento de ansiedade.
ABSTRACT The main causes of mortality are related to chronic non-transmissible degenerative disease. The baru Dipteryx alata Vogel, is a Brazilian cerrado fruit and stands out for its antioxidant and nutritional composition. This work aimed to evaluate the physicochemical composition and the presence of bioactive compounds in crude and roasted baru seeds, to evaluate the metabolic, anthropometric and behavioral profile of Wistar rats. The seeds of baru raw and roasted at 90ºC for 30 min were used to evaluate vitamin C, carotenoids, chlorophyll, antioxidant capacity, total phenolic concentration, anthocyanins and flavonoids. The results of the evaluation of the above parameters did not show significant differences between the raw and roasted almonds. This finding is important because baru seeds can be used in a multitude of industrial products without losing health properties provided by antioxidants such as vitamin C, anthocyanins, carotenoids, flavonoids and chlorophyll. In the metabolic profile of Wistar rats the animals were randomly divided into 4 groups (n = 10): G1 (control group) and G2 (treated with baru 20%); G3 (treated with baru 30%) and G4 (baru treated 40%). After 40 days, the animals were euthanized and the metabolic profiles were analyzed (glycemia, cholesterol, triglycerides, HDL-c, VLDL, LDL-c, CRP, AST, ALT, insulin, Lee index, weight and visceral fat). The use of baru almonds was effective in reducing triglycerides, VLDL-c, LDL-c and increased HDL-c, but did not interfere in the percentage of weight gain, visceral fat and total cholesterol levels. The results show that the use of baru can improve the lipid profile of Wistar rats and we can suggest that the consumption of these almonds or products prepared with them can be an effective option for the intake of healthy products. In the anthropometric and behavioral evaluation of Wistar rats, the results demonstrated that baru kernel reduces food intake and may help prevent body weight gain and visceral fat deposition as well as may help reduce anxiety behavior.
