Exposure of pregnant women to bisphenol A may increase the risk of obesity

A North American study has shown that regular exposure of pregnant women to bisphenol A, a chemical commonly found in plastic products, may increase the risk of obesity in their babies A study led by the American Society of Endocrinology found that young mice born after maternal exposure to bisphenol A during pregnancy were slow to respond to leptin Leptin is a kind of protein hormone secreted by adipose tissue, which can send signals to the hypothalamus to suppress appetite, thus promoting the body to reduce food intake and increase energy release But BPA can change this part of the hypothalamic circuit, which controls diet and energy balance, and make the response of young rats to leptin abnormal Alfonso abizayd, a neuroscientist at the University of Canada, who is the main author of the study, said that prenatal exposure of female rats to bisphenol A would delay the secretion of leptin after birth, and then interfere with the response of young rats to leptin, which belongs to a permanent interference, making young rats more prone to obesity after adulthood Bisphenol A is a kind of endocrine disruptor with estrogen like activity In view of the possible adverse effects of this compound on human development, fertility and nerves, China, the United States and other countries have banned the use of BPA containing materials to manufacture baby bottles.
