Parâmetros bioquímicos da prole adulta de animais tratados com óleo de chia durante a lactação.

Abstract

The importance of maintaining a balanced diet throughout gestation and lactation are key requirements to provide healthy development to the fetus. Among some nutrients, fatty acids are able to cross the placenta during gestation in addition to being present in breast milk. Among food sources containing fatty acids, chia (Salvia hispânica L.) stands out, a seed that contains significant levels of lipids, protein, vitamins, minerals and fiber contents. Through this seed is possible to extract the oil, in which it constitutes an excellent source of α-linolenic acid, besides presenting a high antioxidant power. The objective of this work was to evaluate the effect of the hyperlipid diet with chia oil on the biochemical parameters of offspring of the adult offspring of rats treated during lactation. To obtain amount of animals, nine female Wistar rats aged between 120 and 150 days of age were required to be mated and housed in individual cages, totaling a litter of forty-four animals. The experimental groups were divided according to the type of diet: control group with soybean oil (GC), oil group of Chia (GS) and pig lard group (GB), and received the diet from birth of offspring until the 21st day of lactation. The offspring were housed in cages and divided into three groups according to the diet consumed by the mothers. Adult offspring of infants supplemented with chia oil showed a reduction in the glycemic profile as well as a reduction of the lipid fractions when compared to the control group and to the pig lard group. Regarding hepatic enzymes, there were no significant differences as in the percentage of hepatic fat. Therefore, it is noted that supplementation with chia oil in the maternal diet influences the lipid and glycemic profile of the offspring, thus avoiding the onset of chronic diseases.
