This idea likely grew from two real uses of foil:

- Food preservation (direct contact): Wrapping certain foods in foil really can extend freshness.
From there, the internet ran with it—but science doesn’t back the idea that simply placing a scoop or ball of foil loose in the fridge overnight does much at all.
