Early exposure of dams to a westernized diet has long-term consequences on food intake and physiometabolic homeostasis of the rat offspring

Abstract

This study evaluated the long-term effects of a westernized diet during pregnancy and lactation. Female Wistar rats (n = 12) were divided into two groups according to their food intake, namely, control (C) or westernized (W) diet, throughout pregnancy/lactation. On the 21st day, the male pups were weaned on a standard diet as follows: Control diet (CC) (n = 8) and westernized diet in perinatal life followed by control diet post weaning (WC) (n = 8). The levels of fasting (12 h) serum glucose, triglycerides (TG), and total cholesterol and fraction in the pups were determined. During weaning, the WC group showed 14% greater body weight (p < 0.001). In the adulthood, the offspring from dams fed on westernized diet showed hyperphagia, hyperinsulinism, hypertriglyceridemia, higher fat visceral weight, higher very-low-density-lipoprotein cholesterol level, decreased high-density-lipoprotein cholesterol level, and altered glucose tolerance test. In conclusion, maternal western-style diet in early life altered long-term food intake, visceral fat pad, insulin, glucose and lipid serum, and increased risk of metabolic disorders.

Keywords: Adulthood; food intake; glucose and lipid profile; rat; western-style diet.
