Slicing 1 cup of raw tomato (about one medium-sized fruit) for your lunchtime salad gives you as much as 40 percent of your recommended daily intake of vitamin C and 20 percent of your daily vitamin A -- all for just about 35 calories and zero fat [source: McDonald]. What's not to love?
Tomatoes are a good source of vitamins A, C and E as well as folate and potassium. And in addition to being packed full of vitamins and minerals, studies also have found tomatoes may be antioxidant, antithrombotic, anti-inflammatory and, potentially, anti-cancer powerhouses. They have heart-protective qualities, they help lower cholesterol levels (that's total cholesterol, LDL and triglycerides), and emerging studies find tomatoes also may help with keeping bones healthy.
