Raw Cashews
Eating some nuts, specifically cashews, may also make you sick. These nuts are not actually raw, and instead are processed. Why? Because raw cashews can make you very sick because they naturally have a chemical on them.
Elderberries
You might have heard that elderberries have a lot of health benefits, and this is true. However, only the berry itself is safe. The rest of the plant, including the berries and leaves, contain a chemical that has similar side effects as cyanide!
