Tomatoes

Tomatoes are by far the richest source of a powerful anticancer agent called lycopene. In fact, research has shown lycopene to be an even more powerful disease fighter than vitamin E and beta carotene. Lycopene needs fat for optimal absorption to occur. Therefore, putting the healthy fat olive oil in your spaghetti sauce is an excellent trick to increase your lycopene levels. Start including more tomatoes in your diet in the form of sliced, whole, canned, stewed or sauced tomatoes or tomato paste.
