Copper And Zinc Foods?

[Kray]

And nut intake really isn't that great of a source of zinc, as nuts also have phytic acid that binds zinc.

Better on that front if you soak them in salted water, then low-temp roast them (or dry in dehydrator), deactivates/lowers phytic acid.

All minerals have to be in the soil in order to be in the foods. Copper and zinc are associated with mafic, volcanic geology.

Soaking the oats overnight, as someone mentioned, or buying sprouted oats, reduces phytic acid and makes them more digestible, probably allowing better absorption of the minerals.

Yes, makes sense.

@LauriePartridge - Since you brought up stomach acid, I just came across this anecdotal story about a kid who swallowed a copper coated zinc penny:

When money eats a hole in your stomach

"Most coins are made from copper or nickel, or mixtures of the two. But in
1982, the US replaced its 95 per cent copper one-cent coins with zinc coins
coated with copper. While stomach acid causes little damage to copper and nickel
coins, O’Hara’s says that in her tests it corroded holes through the
copper-plated zinc coins in two days. The US Mint in Washington DC says it has
seen no reaction with one-cent coins that sat in acid for two weeks. But George
Hunter of the mint concedes that the coins might corrode if their coating is
worn.

The reaction of zinc with stomach acid releases toxic zinc chloride, which
O’Hara blames for causing her patient’s ulcer. "

Interesting! Thanks for sharing. Here's another sad but true account of someone ingesting coins:
