The first large study of humans exposed to a chemical widely used in everyday plastics has found that people with higher levels of bisphenol A had higher rates of heart disease, diabetes and liver abnormalities.
BPA is ubiquitous in modern life; it is used to give polycarbonate plastic its shatterproof quality and found in everything from water bottles to dental sealants to the linings of canned food and drinks. The chemical can leach into food and liquid; one recent federal study detected BPA in the urine of 93 percent of the population.
Although the human body quickly metabolizes the chemical, it shows up in steady levels in urine and blood, which means humans are constantly exposed to it.
If you still had any questions… there ya go. For what it’s worth, BPA can be found in some plastic containers with the #7 recycling logo… and sometimes in the #3 apparently.
