Butylhydroxytoluene (BHT) is a fat-soluble preservative that is usually added to foods and cosmetics to slow down autoxidation. Perfluorooctanoic acid (PFOA) is a man-made chemical that is common on cookware to make it more resistant to heat, grease, and stains. Tributyltin (TBT) is used as a stabilizer in plastic products.
What is the common ground on these three chemicals? A new study was published that they all contribute to the obesity epidemic in the U.S.
They tested to see how the chemicals would interfere with the brain signals that told the stomach when it was full or satiated. When the signals were disrupted or the system broke down, it caused people to continue eating and to gain weight.
Out of the three chemicals, BHT was found to be the most harmful. The chemicals disturbed the networks that prepared signaling hormones, rendering them ineffective. One other effect the chemicals had was poor metabolism.
Combined, the effects of the chemicals were even stronger. Moreover, the chemical damage transpired in “young” cells, implicating that pregnant women and their babies would be particularly vulnerable to a defective hormone system.
