Not only are tomatoes a good source of Vitamin C and A, but tudies show that eating tomatoes lower the risk of cancer. The secret may lie in lycopene, the chemical that gives tomatoes it's red color. Processed tomatoes (i.e. canned tomatoes, tomato sauce, ketchup, etc) contain even more lycopene because cooking breaks down cell walls, releasing and concentrating carotenoids. Eating tomatoes with a small amount of fat enables lycopene to be better absorbed by the body. (I often make guacamole and serve with the salsa, this would fulfill that requirement. Cilantro is a blood purifier, and has the ability to bind and excrete toxic heavy metals with efficiency and without unwanted side effects.
