BPA Replacements Show Promise
In the past decade or so, a number of studies have suggested that high exposure to bisphenol A (BPA), a chemical compound used in the lining of many canned foods and drinks (as well as in plastics, to make them tougher), could raise the risk for everything from heart disease to diabetes to weight gain.
BPA can be an endocrine disrupter, leading to wide-ranging health concerns, which has companies scrambling for less-troublesome alternatives. Two possibilities are bisphenol F (BPF) and bisphenol S (BPS), which a University of Iowa investigation found are less likely than BPA to lead to obesity, according to a study published in Lancet Planetary Health in 2017. Studies on other health measures are still needed, but hopefully research like this will spur more food and beverage manufacturers to ixnay BPA from their products. Some canned food companies already have BPA-free packaging on the market.
