Abstract
Adverse early nutrition leads to metabolic aberrations in adulthood. Molecular and cellular mechanisms responsible are emerging; specific nutritional causes remain unclarified. We investigated gestational dietary intake and its influences on metabolism in offspring. Three groups of pregnant Sprague-Dawley rats were fed either AIN93G standard diet as control, isocaloric high fat sucrose diet or calorie restriction diet (50% of control) until delivery. All dams were fed control diet ad libitum during lactation. Offsprings’ metabolic parameters were assessed at three weeks. Visceral fat and plasma triglycerides of high fat sucrose diet offspring were significantly higher than those of control diet and calorie restriction diet offspring. Plasma leptin level was higher in high fat sucrose diet than control offspring. Conversely, plasma adiponectin was lower in high fat sucrose diet and calorie restriction diet offspring compared to controls. Significant inductions of hepatic mRNA expression of stearoyl-CoA desaturase1 and Δ-5 desaturase genes, were observed in high fat sucrose diet and calorie restriction diet offspring. Gestational high sugar and fat intake even without over energy intake would be more detrimental to metabolisms of offspring compared to calorie restriction.
