5 foods every man should eat more of: Tomatoes

3. Tomatoes

Tomatoes and derivative products, such as tomato sauce and ketchup, contain many nutrients that support overall health, but there are two primary reasons they made this list: First, they're a great source of the potent antioxidant lycopene; and second, unlike a couple of other lycopene contenders (namely, watermelon and guava), they're available everywhere year-round.

Research shows a strong association between high lycopene consumption and lower rates of prostate cancer -- the second-leading cause of cancer death in men. In addition to exhibiting preventive effects, lycopene also seems to inhibit the spread of existing cancer and to decrease malignancy. It has shown protective benefits against pancreatic cancer, which is more common in men than women and is one of the most fatal of all cancers, largely due to late diagnosis. Lycopene is also being studied for its effect on male fertility; research suggests that it may boost sperm concentrations in infertile men.

Finally, tomatoes contain phenolic acids, which combat lung cancer, the second most common cancer in men and by far the leading cause of cancer death in both men and women, according to the American Cancer Society.

Quick and healthy tip: Like oatmeal, think of tomato sauce as a base for other healthy ingredients, such as garlic, another potent cancer fighter and an excellent source of vitamin B6 (which combats fatigue and supports the nervous system). Garlic has been associated with a reduced risk of prostate cancer and has shown protective benefits against colon cancer. Plus, it makes any tomato sauce taste better.
