Just because eating a certain food is healthy or good for you doesn't mean you should eat every part of it, or overeat. Some everyday foods could even poison you - when we say poison, we really mean you might suffer a tummy ache or so.

Here are some things you might not have known about these 10 everyday foods that could kill you.

Cherries
Cherry pits are loaded with hydrogen cyanide, so don't try to chew and swallow them.

Wild Almonds
Don't ever eat wild almonds. They're loaded with cyanide and that would be the end of you.

Castor Beans
Castor oil is derived from castor beans, which is a source of ricin when raw.

Apples
You might have gone through a few apple seeds in your lifetime, but eating too many apple seeds causes your body's enzymes to morph compounds in the seeds into cyanide.

Tomatoes
Tomatoes are part of the nightshade family. Their stems, leaves, and green unripe fruit contains toxic alkaloid tomatine.

Elderberries
These are popular in wine and as a medicinal tea. But don't eat the green parts because they contain cyanogenic glycoside sambunigrin, which will cause your system to purge. And that won't be a very pleasant experience for you. 

Kidney Beans
Undercooked kidney beans have a toxin called phytohaemagglutinin. You'd have to vigorously boil them to neutralize it, but just to be safe, get the canned ones.

Lima Beans
Uncooked legumes are loaded with cyanide.

Potatoes
Stay clear from green potatoes. They're packed with solanine, which will make you puke. Also eating too much of this will cause cardiac arrest.

Rhubarb
The leaves of rhubarb stalks contain oxalic acid, which is bleach.
