Alterações murinométricas, curva ponderal e consumo alimentar na prole de ratas tratadas com óleo de chia durante a lactação.

Abstract

Prenatal and postnatal nutrition is an important influential factor in the predisposition of some chronic noncommunicable diseases such as obesity. Research suggests that supplementation with polyunsaturated fatty acids, in particular omega-3, has shown some benefits in preventing some diseases and influencing the metabolism of adult offspring. Therefore, the objective of this study was to evaluate the effect of chia oil on murinometric parameters, body weight and visceral fat in the offspring of treated rats during lactation. Female wistar rats were treated during the lactation phase. Mothers were divided into three groups: Control (100% commercial standard diet), Chia (95% commercial standard diet + 5% chia oil) and Banha (95% commercial standard diet + 5% lard) and after 21 ° day of lactation the pups were weaned and then started to consume standard diet. Body weight and feed intake were measured weekly. At 70 days of age, the animals were anesthetized for murinometric evaluation. Posteriorly the fats were removed and quantified. The results showed that the weekly consumption of the chia group was lower than the control group consumption from the 1st to the 5th week and lard group from the 2nd to the 5th week (p <0.05). The body weight of the animals in the chia group was lower than the control group at the 1st, 4th, 5th and 6th weeks (p <0.05) and lard group during the whole experiment (p <0.05). The BMI and waist circumference of the chia group was lower than the control and lard groups (p <0.05). The thoracic circumference was higher in the lard group compared to the control group and Chia (p <0.05). The total visceral fat of the offspring of the Chia group was also smaller compared to the control group (p> 0.05). Therefore, probably the quality of Chia oil rich in polyunsaturated fatty acids, omega 3 has influenced the satiety increase and consequently lower food consumption as well as favored increase of beta-oxidation of fatty acids to provide energy for offspring growth.
