--Sharing is Caring--

University of Iowa conducted a study which shows that BSF and BSF used in making plastic food containers, water bottles, and other consumer products does not contribute to obesity unlike its counterpart BPA.

BPF (Bisphenol F) and BPS (Bisphenol S) which is broadly used as alternatives to BPA (Bisphenol A) in food packaging industries have been found to disrupt endocrine systems and causes numerous health problems. BPA is used in many kinds of packaging for snacks and drinks, canned foods, and water bottles. The chemical is absorbed into the body mainly through seeping into food or water it contacts in the container.

BPA was the matter of concern few years ago when many studies showed that it increases the risk of various health issues, especially obesity, diabetes, and cardiovascular diseases. Criticism from consumers blew up after the studies received media attention so manufacturers started using alternatives like BPF and BSF in consumer products thereby eliminating the usage of BPA. “BPA-free” products were introduced into the market by replacing it with such alternatives as BPF and BPS.

Nevertheless, not much is known regarding the potential hazard BPF and BPS could cause by exposure in humans. Health impacts of BPF and BPS exposure on obesity in humans was first determined by the studies conducted from The new University of Iowa . Using statistics from a countrywide population-based study, conducted by the U.S. Centers for Disease Control (CDC), the researchers confirm that BPA is associated with increased obesity in humans. But the study found no links between obesity and the two chemicals (BPF or BPS) at the present exposure levels.

However, the researchers’ warn that only smaller amount of products currently use BPF and BPS. It’s seen that BPA still has more than half the international market share for the chemicals, and the average concentration of BPF and BPS is about one-fourth to that of BPA in the US population.

Whether BPF and BPS pose an increased risk of obesity as BPA remains unsolved. Future studies are looked-for to confirm the results, as BPF and BPS are likely to replace BPA in more consumer products.
