π No doubt you've heard about Sardine's superpowers. No doubt you've also heard me say that every food has a dark side
Sardines can be a BPA bomb and contain arsenic, especially when oil packed
Of course, they contain significant omega 3, but unfortunately they are heated to 250Β°. Such fragile oils begin to degrade at 120Β°
Additionally, the heat increases leaching of BPA from the plastic liner in the can
Increasingly modern cans are BPA-free, but while the body of the can may not contain BPA, the lid does. Unlike most can's, Sardine tin lids have as much surface area as the body
BPA-free doen not mean toxin free. BPA alternatives are likewise toxic: BPA is being replaced with BPS or BPF, which are similar, less studied, and often equally harmful analogs. "BPA-free" labels do not guarantee the absence of these similar endocrine-disrupting neurotoxic chemicals. See the previous posts on my Profile page for their detailing this
Furthermore, tin lined cans usually contain epoxy resins, polymers or enamel/lacquer
If it weren't for all these toxins, Sardines would indeed be a superfood.
If you are a Sardine lover like myself, you'll appreciate this workaround.
Look for salt water pack, glass container and long expiration date 4+ years
