Worldwide prevalence of noncommunicable chronic degenerative diseases is among the main causes of death worldwide. The consumption of some foods such as nuts and seeds may be beneficial in preventing these diseases. Dipteryx alata Vogel (DA), known popularly as Baru, belongs to the family Fabaceae and is a native fruit tree from the Brazilian savanna. The purpose of this study was to evaluate the use of seeds of DA on the metabolic and oxidative profile of Wistar rats. Animals were divided randomly into four groups (n = 10): G1 (control group), and G2 (treated with DA 20%), G3 (treated with DA 30%), and G4 (treated with DA 40%). After 40 days, animals were euthanized and metabolic and oxidative profiles were analyzed (glycemia, cholesterol, triglycerides [TGs], high-density lipoprotein-cholesterol [HDL-c], very low-density lipoprotein-cholesterol [VLDL-c], low-density lipoprotein-cholesterol [LDL-c], C reactive protein, aspartate aminotransferase, alanine aminotransferase, Lee index, weight, visceral fat, ferric reducing ability of plasma, and ferric-xylenol orange method. The use of the seeds was effective in reducing TGs, VLDL-c, LDL-c, and increasing HDL-c but did not interfere in the percentage of weight gain, visceral fat, levels of total cholesterol, and oxidative stress. Based on our results, it is possible to say that the use of DA may improve the lipid profile of Wistar rats and we may suggest that the consumption of DA almonds or products prepared with them may be an effective option for the intake of healthy products.
