Efeitos do consumo da amêndoa e do óleo de baru (Dipteryx Alata Vog.) sobre parâmetros bioquímicos e de ansiedade em ratas tratadas durante a gestação e lactação

Abstract

During gestation and lactation, deficiencies in essential fatty acids correlate to negative maternal health impacts. Baru almonds are a good source of such fatty acids. The objective of this study was to evaluate the effects of maternal Baru almond flour and oil consumption (during gestation and lactation) on physical, biochemical, metabolic and anxiety parameters at the end of lactation. The animals were divided into three groups: Control treated with distilled water; Oil treated with 2.000 mg Baru oil/kg animal weight; and Almond treated with 2.000 mg solution containing Baru flour (almond)/kg animal weight. Anxiety was measured using open field devices, elevated plus maze, and the light-dark box. Fatty acid profiles of the liver and brain, as well as physical, metabolic, and biochemical parameters were evaluated. A reduction in anxiety was observed in the mothers treated either with Baru oil or flour (p <0.05). The Oil and Almond groups presented lower plasma glucose, and lower total cholesterol and triglyceride levels (p <0.05). Renal and hepatic functions were unchanged in all experimental groups (p <0.05). For the respective Oil and Almond animals tissues, the liver and brain lipid profile results presented increases in mono and polyunsaturated fatty acid levels (p <0.05). The results demonstrate that maternal supplementation with Baru oil and flour can reduce maternal anxiety at the end of lactation, modulate biochemical profiles, and prevent renal and hepatic damage.
