20 Deadly Foods You Didn’t Know Could Kill You
5. Cinnamon
There was a cinnamon challenge on the internet where people were dared to eat spoonfuls of the substance, but the American Association of Poison Control Center issued a warning that if this spice gets in the lungs, it can lead to death.

6. Mushrooms
When cooked properly, many mushrooms are safe to consume. When shiitake mushrooms aren’t cooked well enough, they can lead to intense body rashes, and other mushrooms, like the death cap, can kill you instantly.

7. Apple seeds
The seeds in apples have amygdalin, which is a mix of cyanide and sugar that turns into hydrogen cyanide when digested. In small amounts, it’s ok, but if you eat many seeds, issues can arise.

8. Potatoes
Eat them boiled, baked, or in a mash, and they’re fine. But eating green potatoes or drinking tea made of potato leaves is deadly, as this food has poisonous leaves and hands.
