Influência do consumo materno da polpa de óleo de abacate (Persea Americana Mill.) sobre os parâmetros físicos e bioquímicos da prole de ratas wistar.

Abstract

During the gestation and lactation periods, considered critical for development, lipids, especially fatty acids (FA), are considered indispensable for tissue construction and determination of body growth and are transferred to the fetus through the placenta. through simple and facilitated diffusion and through breast milk respectively. Thus, maternal nutrition has a strong influence on fetal and postnatal development, and can program offspring metabolism, modifying morphological and physiological parameters, which may be associated with future health and disease susceptibility. Therefore, this study aimed to investigate the effects of maternal consumption of avocado pulp and oil (Persea Americana Mill.) On the murinometric and biochemical parameters of offspring of wistar rats.Twenty-four primiparous females were used to obtain 45 male pups, which were divided into three groups: Control (CG) - supplemented with distilled water; Avocado Oil (OA) Group (n = 10) - supplemented with avocado oil; and Avocado Pulp Group (PA) - treated with lyophilized avocado pulp, the administration occurred by gavage. At 45 days of life half of the animals from each group were anesthetized and euthanized, and the murinometric and biochemical evaluations were performed. The same procedures were performed at 90 days of life of the other animals. The results were submitted to one-way analysis of variance, with the application of Tukey test, being considered significant difference when p <0.05. Based on the data obtained, avocado pulp supplementation influenced the reduction in consumption and weight gain in adult offspring; in body weight, BMI, thoracic and abdominal circumference; decreased visceral fat; reduced blood glucose, LDL and atherogenic index; in addition to preserving liver function. On the other hand, avocado oil has had the opposite effects. Thus, we can conclude that the consumption of avocado oil and pulp caused different schedules in the offspring of rats treated during pregnancy and lactation. The maternal supplementation of avocado pulp reflected in more positive results regarding avocado oil. Thus, it is understood that avocado pulp is a potential food to be consumed during pregnancy and lactation.
