Possible health benefits of tomatoes

The benefits of consuming fruits and vegetables of all kinds, including tomatoes, are infinite. As plant food consumption goes up, the risk of heart disease, diabetes, and cancer goes down.

High fruit and vegetable intake is also associated with healthy skin and hair, increased energy and lower weight. Increasing consumption of fruits and vegetables significantly decreases the risk of obesity and overall mortality.

1) Cancer

As an excellent source of the strong antioxidant vitamin C and other antioxidants, tomatoes can help combat the formation of free radicals known to cause cancer.

2) Prostate Cancer

Lycopene has been linked with prostate cancer prevention in several studies.⁷ According to John Erdman, Ph.D., Professor Emeritus of the department of food science and human nutrition at the University of Illinois, "There's very good, strong, epidemiological support for increased consumption of tomato products and lower incidence of prostate cancer."⁷

Among younger men, diets rich in beta-carotene may play a protective role against prostate cancer, according to a study conducted by the Harvard School of Public Health's Department of Nutrition.

3) Colorectal Cancer

Beta-carotene consumption has been shown to have an inverse association with the development of colon cancer in the Japanese population. High fiber intakes from fruits and vegetables are associated with a lowered risk of colorectal cancer.

According to the American Cancer Society, some studies have shown that people who have diets rich in tomatoes may have a lower risk of certain types of cancer, especially cancers of the prostate, lung, and stomach. Further human-based research is needed to find out what role lycopene might play in the prevention or treatment of cancer.

4) Blood pressure

Maintaining a low sodium intake is essential to lowering blood pressure, however increasing potassium intake may be just as important because of its vasodilation effects. According to the National Health and Nutrition Examination Survey, fewer than 2 percent of U.S. adults meet the daily 4700 mg recommendation.³

Also of note, a high potassium intake is associated with a 20 percent decreased risk of dying from all causes.³

5) Heart health

The fiber, potassium, vitamin C and choline content in tomatoes all support heart health. An increase in potassium intake along with a decrease in sodium intake is the most important dietary change that a person can make to reduce their risk of cardiovascular disease, according to Mark Houston, M.D., M.S., an associate clinical professor of medicine at Vanderbilt Medical School and director of the Hypertension Institute at St. Thomas Hospital in Tennessee.³

In one study, those who consumed 4069 mg of potassium per day had a 49 percent lower risk of death from ischemic heart disease compared with those who consumed less potassium (about 1000 mg per day).³

High potassium intakes are also associated with a reduced risk of stroke, protection against loss of muscle mass, preservation of bone mineral density and reduction in the formation of kidney stones.³

6) Diabetes

Studies have shown that type 1 diabetics who consume high-fiber diets have lower blood glucose levels and type 2 diabetics may have improved blood sugar, lipids and insulin levels. One cup of cherry tomatoes provides about 2 grams of fiber.

The Dietary Guidelines for Americans recommends 21-25 g/day for women and 30-38 g/day for men.

7) Skin

Collagen, the skins support system, is reliant on vitamin C as an essential nutrient that works in our bodies as an antioxidant to help prevent damage caused by the sun, pollution and smoke, smooth wrinkles and improve overall skin texture.⁵

8) Constipation

Eating foods that are high in water content and fiber like tomatoes can help to keep you hydrated and your bowel movements regular. Fiber is essential for minimizing constipation and adding bulk to the stool.

9) Pregnancy

Adequate folic acid intake is essential for pregnant women to protect against neural tube defects in infants.

10) Depression

The folic acid in tomatoes may also help with depression by preventing an excess of homocysteine from forming in the body, which can prevent blood and other nutrients from reaching the brain.
