- Abstract
Pregnancy is a period that is characterized by several metabolic and physiological changes and requires special attention, especially with regard to the relationship between feeding and foetal development. Therefore, the objective of this study was to evaluate whether the practice of voluntary physical exercise (VPE) in combination with chronic consumption of fructose (FRU) from the beginning of life and/or until the gestational period causes genotoxic changes in pregnant females and in their offspring. Seventy Swiss female mice received FRU in the hydration bottle and/or practiced VPE for 8 weeks (prepregnancy/pregnancy). After the lactation period, the offspring groups were separated by sex. It was observed that the consumption of FRU affected the food consumption, serum concentration of FRU, and glycemic profile in the mothers and that the VPE decreases these parameters. In addition, FRU was genotoxic in the mothers' peripheral tissues and VPE had a preventive effect on these parameters. The offspring showed changes in food consumption, serum FRU concentration, and body weight, in addition to an increase in the adiposity index in male offspring in the FRU (FRU) group and a decrease in the FRU + VPE group. FRU leads to hepatic steatosis in the offspring and VPE was able to decrease the area of steatosis. In addition, FRU led to genotoxicity in the offspring and VPE was able to modulate this effect, reducing damages. In conclusion, we observed that all interventions with VPE had nutritional, genetic, and biochemical benefits of the mother and her offspring.
