What BPA Does to You

BPA (bisphenol A) is a type of endocrine disrupting chemical found in hard plastics, in the lining of tin cans, food storage containers, and receipts. BPA is estrogenic, meaning it imitates the female hormone estrogen in the body. 

BPA has extremely strong links to weight gain and obesity, for men, women, girls, and boys

BPA has also been linked to asthma, immune disorders, and lowered IQ in children. 

Along with most endocrine disrupting chemicals, BPA hurts fertility

BPA is especially bad for children in the womb. Children are undergoing rapid development during this time and even small amounts of artificial hormones can harm them. 

How You Can Avoid Exposure to BPA

The most common source of exposure to BPA is food or drink. BPA is used to make hard, clear plastics. That means BPA is in a lot of plastic food storage and water bottles. You should never microwave plastic. When you do that it releases microplastics and BPA into your food. 

The lining of tins cans often have BPA as well. Don’t trust products that claim to be ‘BPA free.’ Those labels are rarely honest. Most of those products contain BPS and BPF instead. Technically they aren’t BPA, but they’re just as bad for you and your loved ones, maybe worse. Anything stored in glass, ceramic, frozen, dried is pure and clean.

The best thing about BPA is that if you stop exposure it will quickly flush out of your body, usually within 48 hours. Unfortunately, nearly all unprotected Americans have steady levels of BPA in their blood, since we’re frequently exposed. 

BPA is not the only common endocrine disrupting chemical in your home. If you haven't heard of them already, you should learn about phthalates
