Antioxidants in pregnancy prevent obesity in animal offspring
Date:3/14/2011

one group of rats, compared to a control group fed a more balanced diet. In two other groups (one fed a Western diet, the other fed a control diet), the researchers added antioxidant vitamins.

Among the rats that ate only the Western diet, the offspring had significantly higher measures of inflammation and oxidative stress, and as early as two weeks of age, were significantly fatter, with impaired glucose tolerance compared to control rats. However, rats eating the Western diet plus antioxidants had offspring with significantly lower oxidative stress, as well as no obesity and significantly better glucose tolerance. The effects persisted at two months of age.

“These results suggest that if we prevent obesity, inflammation and oxidative stress in pregnant animals, we can prevent obesity in the offspring,” said Simmons. Simmons added that a next step in this research is to determine the mechanisms by which inflammation and oxidative stress cause more fat tissue to develop.

She cautioned that until these effects are carefully studied in people, one shouldn’t conclude that the biological effects seen in animals are the same in humans. In the meantime, she added that, whether pregnant or not, women should certainly not conclude from this study that they should consume large doses of antioxidant vitamins.
