Popcorn
Popcorn: high in oxalates; low in nickel. If you're sensitive to any of these, check it against your profile before eating.
Intolerances
- OxalatesHigh
Popcorn is high in oxalate by weight (about 54 mg per 100 g air-popped, 41 mg oil-popped) because popping removes the water and concentrates it — fresh sweetcorn is only about 1 mg per 100 g. Popcorn is very light though, so a cup weighs roughly 8 g and carries only 4-5 mg. A small bowl is modest; a large sharing bag is not.
- NickelLow
Popcorn is whole maize kernels burst by heat - nothing is removed, but nothing was there in quantity either. Maize is a low-nickel grain, and heat does not concentrate a metal.
