> BPA is a known endocrine disruptor. Although initially considered to be a weak environmental estrogen, more recent studies have demonstrated that BPA may be similar in potency to estradiol in stimulating some cellular responses. https://pubmed.ncbi.nlm.nih.gov/21605673/ > In 2017 the European Chemicals Agency concluded that BPA should be listed as a substance of very high concern due to its properties as an endocrine disruptor.[30] In 2023, the European Food Safety Authority re-evaluated the safety of BFA and significantly reduced tolerable daily intake (TDI) to 0.2 nanograms (0.2 billionths of a gram), 20,000 times lower than the previous TDI from 2015. > In 2012, the United States' Food and Drug Administration (FDA) banned the use of BPA in baby bottles intended for children under 12 months.[31] The Natural Resources Defense Council called the move inadequate, saying the FDA needed to ban BPA from all food packaging. https://en.wikipedia.org/wiki/Health_effects_of_Bisphenol_A > This followed another paper in early 2024, where a group of Italian researchers identified microplastics in plaques found in the carotid arteries – a pair of major vessels which deliver blood to the brain – of people with early-stage cardiovascular disease. This linked their presence to worsening disease progression. Over the following three years, individuals carrying these microplastics in their plaques had a 4.5-fold greater risk of stroke, heart attack or sudden death. > Then in February 2025, another group of scientists identified microplastics in the brains of human cadavers. Most notably, those who had been diagnosed with dementia prior to their death had up to 10 times as much plastic in their brains compared to those without the condition. "We were shocked," says Matthew Campen, a University of New Mexico toxicology professor who led this study. https://www.bbc.co.uk/future/article/20250723-how-do-the-mic... | |||||||||||||||||

This is exactly the kind of fear mongering reporting I was talking about and explains the general public's warped perception described in the research review I linked above. If you look at the brains of dead people with dementia, you'll also find more aluminum, which has caused people to panic about antiperspirants. But there is zero actual causal evidence that Al exposure causes dementia, if you do the science right. The same goes btw. for amyloid plaques, which has actually hindered real Alzheimer's research. So not even scientists are safe from the correlation!=causality problem. You can make up all kinds of potential hazards by comparing similar molecules and inventing bioavailability pathways. But at the end of the day this is just speculation and you need hard data to prove these assumptions. | |||||||||||||||||
