Can bisphenol S from 'BPA-free' products damage your heart?
Some Concern
What's actually in it
Bisphenol S (BPS) replaced BPA in "BPA-free" products including receipt paper, food cans, and plastic containers. Like BPA, BPS enters your body through skin and food contact. It circulates in your blood and reaches your heart and blood vessels.
What the research says
A 2026 study in Environ Res found that BPS exposure caused cardiac remodeling, physical changes to the heart's structure that can lead to heart failure. The damage was linked to disruption of the renin-angiotensin system (RAS), the hormone system that controls blood pressure and fluid balance.
When the RAS is thrown off balance, the heart works harder than it should. Over time, this leads to thickening of the heart muscle, stiffening of the chambers, and eventually reduced pumping ability.
Don't trust "BPA-free" labels as proof of safety. Use glass, ceramic, or stainless steel for food and drinks. Decline paper receipts, which are a top source of BPS exposure.
