The researchers orally administered doses of BPA to the rats that were equivalent to about 10 times less than the daily amount considered safe for humans, a statement from the Toulouse institute said.
They saw that BPA reduced the permeability of the instentinal lining through which water and essential minerals enter the body, it said.
They also found that newborn rats exposed to BPA in the uterus and during feeding have a higher risk of developing severe intestinal inflammation in adulthood.
The study 'shows the very high sensitivity on the intestine of Bisphenol A and opens news avenues for research' including to define new acceptable thresholds of the substance for humans, the institute said."
National Institute of Agronomic Research researchers in Toulouse found the digestive tract of rats react negatively to even low doses of the chemical also called BPA, the Proceedings of the National Academy Sciences journal reported.
