23 Surprising Foods You Should Never Eat Raw

Tomatoes

Although tomatoes can be eaten raw, a study by Cornell University scientists showed that the antioxidant activity of cooked tomatoes is higher than in uncooked tomatoes. This suggests that to get more benefits out of tomatoes, they should be cooked before eating. Tomatoes ranked number 10 as one of the vegetables with pesticide residue, so they should be washed first. The stems, leaves, and unripe tomatoes are poisonous and should not be eaten.
