These common foods can be so dangerous, they can kill you

Potatoes

The leaves, stem and sprouts of potatoes contain glycoalkaloids, which are also found in deadly nightshade. If your potatoes have started to sprout, it’s best to throw them away rather than just cut the sprouts off, in case the poison has gone into the potato. Scientists claim that a person weighing 100 pounds would have to eat 16 oz of a sprouted potato to get ill.
