(Natural News) While canned goods and chips may not be healthiest foods in the world, new research has revealed that they’re even worse than originally thought. The preservatives and chemical additives that help these foods maintain their freshness may actually disrupt metabolism and lead to obesity. That’s what investigators from Cedars-Sinai Medical Center in Los Angeles, Calif., found out after testing the effects of known endocrine disruptors in the human body.
In the new study, published in Nature Communications, the researchers tested butylhydroxytoluene (BHT), perfluorooctanoic acid (PFOA), and tributyltin (TBT). BHT is a fat-soluble preservative that is usually added to foods and cosmetics to slow down autoxidation; PFOA is a man-made chemical that is common on cookware to make it more resistant to heat, grease, and stains; and TBT is used as a stabilizer in plastic products.
For the experimental part of their study, the researchers obtained blood samples from adult participants then converted these cells into induced stem cells which they then grew into two different kinds of tissues. The first was epithelial tissues similar to those lining the digestive tract, and the second was the neuronal tissues from the hypothalamus, the region of the brain that controls metabolism and appetite.
One by one, and in combination, the researchers exposed the tissues to the three chemicals while observing what occurred within the cells. Specifically, 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…Read More
