Inside the packaging of most canned foods contain bisphenol-A (BPA) a chemical that acts like estrogen that disrupts hormonal activity of the organism.
Studies have linked BPA with heart disease, damage to intestines, infertility and other reproductive problems. According to the US Center for Disease Control and prevention of diseases, exposure to BPA is widespread worldwide. Although all canned foods are not recommended, canned tomatoes are especially dangerous because due to their high acidity BPA lingers in them.
The FDA (Food and Drug Administration) is continuing its review of BPA, including supporting ongoing research. In the meantime, if you’re concerned about BPA, you can take these steps to reduce your exposure:
- Use BPA-free products. Manufacturers are creating more and more BPA-free products. Look for products labeled as BPA-free. If a product isn’t labeled, keep in mind that some, but not all, plastics marked with recycle codes 3 or 7 may be made with BPA.
- Cut back on cans. Reduce your use of canned foods since most cans are lined with BPA-containing resin.
- Use alternatives. Use glass, porcelain or stainless steel containers for hot foods and liquids instead of plastic containers.
