The Effect of Plastic Products on Autoimmune Disease and Thyroid Function: Stop Using Plastic Coffee Lids!

When managing Hashimoto’s or any autoimmune disease, one goal is to avoid triggers that cause flare ups. Although avoiding dietary triggers — such as gluten, grains, dairy, GMOs, lectins, etc. — is foundational, did you know environmental triggers can cause flare ups too?

For example, one of the most common and most overlooked autoimmune triggers is bisphenol-A (BPA). BPA is found in all plastics, including water bottles, plastic coffee lids, the lining of cans, plastic utensils, and even in the ink on store receipts. Although it is impossible to completely avoid plastics, it is critical for you to reduce your exposure to plastics and BPA as much as possible if you have Hashimoto’s.

Plastic coffee lids and drink bottles some of worst offenders for BPA exposure

One of the worst forms of BPA exposure is from plastic products exposed to heat or acidic chemicals — making plastic coffee lids and drink bottles primary offenders. As coffee or tea passes through a plastic coffee lid, both the heat and the acidity leach very high levels of BPA into your drink. Also, small amounts of BPA insulate the coating of paper cups. If you have Hashimoto’s or autoimmunity, simply avoid using the lid and, even better, brew your own coffee or tea and drink from glass or ceramic cups.

It’s also important to avoid plastic bottles, especially if they are heated or contain an acidic beverage such as soda or fruit juice. You should absolutely never drink an acidic beverage from a plastic bottle as you will be drinking high amounts of BPA.

Avoid daily exposures to BPA

The key issue with BPA and autoimmunity is to eliminate daily sources of exposure. For example, if you drink coffee every morning through a plastic lid and drink water or other drinks from plastic bottles every day you can dramatically reduce your exposure to BPA by forgoing the coffee lid and drinking from glass bottles.
