Since the 1950s manufacturers discovered that lining the inside of their tins with bisphenol A (BPA) epoxy resins strengthened the tins and extended shelf life. But BPA is also an endocrine disruptor the effects of which have been linked to an increased risk of breast, lower sperm counts in men and prostate cancer, infertility, type 2 diabetes, obesity, asthma, and ADHD.
BPA-free food cans
Eden Foods grocery store set up in 1968 is now the oldest organic food produce in the US. In 1997, Eden Foods became alarmed by the toxicity of bisphenol-A (BPA) in cans and food packaging long before it made it to mainstream news. From April of 1999, Eden beans have featured a custom made can lined with an oleoresinous c-enamel that does not contain the endocrine disrupter.
Oleoresin is a mixture of oil and resin extracted from plants such as pine or balsam fir. Since then Eden uses BPA-free enamel-lined cans for most of its products (the only exception being tomato-based foods). After years of trying to realise a BPA-free tomato can, in 2011 Eden found an alternative in the amber glass jar.
Recently, some of the world’s biggest food companies such as Nestlé, Heinz, General Mills and Campbell Soups have attempted to remove BPA from their products. Several other firms, such as Coca-Cola, declined to disclose a timetable for its withdrawal, saying that BPA was safe.
The UK’s Food Standards Agency has examined BPA, and says that levels of the compound people would typically consume do not represent a risk to consumers.
