Red tomatoes are popular for their flavor and versatility. You'll find fresh tomatoes in the produce section of your grocery store as well as in many processed foods like pasta sauce and salsa. Tomatoes are much more than flavorful: They're also good for you. Tomatoes are rich in potassium, vitamin A, vitamin C and lycopene that works as an antioxidant to protect the cells in your body. Tomatoes are also low in calories.

Eating Tomatoes May Help Reduce Your Cancer Risk

A Harvard study done in 1995 showed men who ate a lot of tomatoes appeared to have a lower risk of prostate cancer. This effect is largely attributed to lycopene. However, some studies suggest a synergistic effect of the vitamins also found in tomatoes. Lycopene is actually related chemically to vitamin A.

According to the American Cancer Society, there is also strong evidence that lycopene-rich foods may help protect against lung and stomach cancer. There is also evidence that lycopene may help prevent several other forms of cancer as well.

Tomatoes For a Healthy Heart

The antioxidants found in many colorful fruits and vegetables help to protect your heart, and tomatoes are no exception. Studies indicate that people with low levels of lycopene in their bodies may be more likely to suffer from heart disease. Lycopene may decrease inflammation and reduce LDL cholesterol, both of which may help keep your heart healthier.

Healthy Ways to Enjoy Tomatoes

Tomatoes are good for you whether you eat them fresh, like on a salad or sandwich, or when cooked into a sauce. Bite-sized cherry tomatoes make a delicious snack when dipped into your favorite veggie dip and plump roma tomatoes are perfect for making sauces. While cooking reduces the vitamin C, the lycopene becomes more concentrated. Here are some healthy tomato recipes:
