Don’t Let This Stop You From Eating More Canned Fish
Let’s talk about BPA
Editor’s note: After highlighting the health, cost, and environmental benefits of eating canned fish, Heated received a wide array of feedback. The piece validated canned fish lovers around the globe, opened the minds of former naysayers (we’ve received an unusual number of photos of people trying sardines for the first time), and surfaced several questions and concerns. The most common questions related to concerns about bisphenol A, or BPA, in canned foods, so the following is an exploration of those concerns.
BPA is not good for you. In the early 1990s, BPA was discovered to have a very similar biological structure to the hormone estrogen, resulting in endocrine-disrupting effects. In animal and epidemiological studies, researchers have linked BPA to breast and prostate cancer, reduced fertility, diabetes, genital defects, altered behavior, and weight gain.
BPA is a chemical that is often used to make polycarbonate plastics and epoxy resins and has been used in food and beverage containers since the 1960s. Epoxy resins serve as the extremely thin plastic lining found inside an aluminum can. The purpose of this lining is to prevent food from losing flavor or spoiling and to prevent the tin from getting worn out or rusted. No one wants rusted anchovies.
