Efeito da suplementação com azeite de dendê nos padrões murinométricos, consumo alimentar e na gordura visceral de ratos Wistar.

Abstract

Obesity is the excessive accumulation of body fat, being listed as an important risk factor for a number of diseases. It can be caused by a number of factors, but particularly by ingestion of calorie foods, associated with sedentary. The palm oil or palm oil, consisting of a vegetable oil, extracted from palm fruit mesocarp Elaeis guineenses, used to supply the Northeast. It has about 50% saturated fatty acids, 40% monounsaturated and 10% polyunsaturated. The objective of this research was to analyze the effects of palm oil supplementation in murinométricos parameters and food consumption in rats. The animals received a commercial diet (Presence – Purinas ®) and water ad libitum. Palm oil was offered by gavage (1ml/kg). The control group (CG) received distilled water. After being anesthetized, the animals were sacrificed by cardiac puncture. The body weight of animals was measured daily. Food intake was measured monthly. The length, chest circumference and abdominal animal was measured using a tape measure for analysis of parameters and murinométrics, along with the weight used to calculate the Body Mass Index. Visceral fat was removed and heavy. Palm oil had no effect on body weight, feed intake and was not enough to change the coefficient of feeding efficiency. The groups did not show statistical difference in the morphometric parameters, but there was difference in the abdominal circumference / chest circumference (AC / CT), indicating changes in body fat of mice. Found greater accumulation of fat in the group supplemented with palm oil as compared to the control group (P = <0,05) confirming previous results, where the accumulation of visceral fat is reflected in the ratio AC / CT. Based on the results, it is concluded that palm oil consumption induces the gradual accumulation of visceral fat in rats.
