Tomato is the edible, often red fruit/berry of the nightshade Solanum lycopersicum, commonly known as a tomato plant. Tomato is consumed in diverse ways, including raw, as an ingredient in many dishes, sauces, salads, and drinks. The fruit is rich in lycopene, which may have beneficial health effects.
One serving of red, ripe, raw tomatoes (one cup or 150 grams) is a good source of vitamin A, C, K, folate and 534 milligrams of potassium. Tomatoes are naturally low in sodium, saturated fat, cholesterol, and calories. Tomatoes also provides thiamin, niacin, vitamin B6, magnesium, phosphorus and copper. One serving of tomatoes gives 2 grams of fiber, which is 7% of the daily recommended amount. Tomatoes also have a relatively high water content, which makes them a filling food.
Health Benefits
Tomatoes are a treasure of riches when it comes to their antioxidant benefits. Tomatoes provide an excellent amount of vitamin C and beta carotene; a very good amount of the mineral manganese; and a good amount of vitamin E. In terms of phytonutrients, tomatoes are basically off the chart, and include:
- Flavonones: naringenin, chalconaringenin
- Flavonols: rutin, kaempferol, quercetin
- Hydroxycinnamic acids: caffeic acid, ferulic acid, coumaric acid
- Carotenoids: lycopene, lutein, zeaxanthin, beta carotene
- Glycosides: esculeoside A
- Fatty acid derivatives: 9-oxo-octadecadienoic acid
Alpha-lipoic acid helps the body to convert glucose into energy. Some evidence suggests that alpha-lipoic acid can aid in blood glucose control, improve vasodilation and protect against retinopathy in diabetic patients and may even help preserve brain and nerve tissue.
Choline is an important nutrient found in tomatoes that helps with sleep, muscle movement, learning and memory. Choline also helps to maintain the structure of cellular membranes, aids in the transmission of nerve impulses, assists in the absorption of fat and reduces chronic inflammation.

Tomatoes do not have to be a deep red color to be an outstanding source of lycopene. Lycopene is a carotenoid pigment associated with the deep red color of many tomatoes. Lycopene from orange- and tangerine-colored tomatoes may actually be better absorbed than the lycopene from red tomatoes. That's because the lycopene in deep red tomatoes is mostly trans-lycopene, and the lycopene in orange/tangerine tomatoes is mostly tetra-cis-lycopene.
Fresh tomatoes and tomato extracts have been shown to help lower total cholesterol, LDL cholesterol, and triglycerides. In addition, tomato extracts have been shown to help prevent unwanted clumping together (aggregation) of platelet cells in the blood - a factor that is especially important in lowering risk of heart problems like atherosclerosis.
Anti-Cancer Benefits
Tomatoes can definately help lower risk of prostate cancer in men. One key tomato nutrient that has received special focus in prostate cancer prevention is alpha-tomatine. Alpha-tomatine is a saponin phytonutrient and it's shown the ability to alter metabolic activity in developing prostate cancer cells. It's also been shown to trigger programmed cell death (apoptosis) in prostate cancer cells that have already been fully formed. Research on alpha-tomatine has also been conducted for non-small cell lung cancer, with similar findings.
Research on tomatoes and breast cancer risk has largely focused on the carotenoid lycopene, and there is fairly well documented risk reduction for breast cancer in association with lycopene intake.
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.

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. A high potassium intake is associated with a 20 percent decreased risk of dying from all causes.
Heart Health
The fiber, potassium, vitamin C and choline content in tomatoes all support heart health. An increase in pottasium 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. 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). 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.
Strong Bones
Tomatoes build strong bones. The vitamin K and calcium in tomatoes are both very good for strengthening and repairing bones. Lycopene also has been shown to improve bone mass, which is a great way to fight osteoporosis.
Blood Sugar
Tomatoes can keep blood sugar in balance. Tomatoes are a very good source of chromium, which helps to regulate blood sugar.
Vision
Tomatoes can improve your vision. The vitamin A that tomatoes provide can improve vision and help prevent night blindness. Recent research shows that consuming tomatoes may help reduce the risk of mascular degeneration, a serious and irreversible eye condition.
Chronic Pain
Tomatoes can reduce chronic pain. If you are one of the millions of people who deal with mild to moderate chronic pain (such as from arthritis and back pain), tomatoes may be a painbuster. Tomatoes are high in bioflavonoids and carotenoids, which are known anti-inflammatory agents. Chronic pain often involves chronic inflammation, so attacking the inflammation is a good way to fight the chronic pain.
Depression
The folic acid in tomatoes may also help with depression by preventing excess of homocysteine from forming in the body, which can prevent blood and other nutrients from reaching the brain. Excess homocysteine interferes with the production of the feel-good hormones serotonin, dopamine, and norepinephrine, which regulate not only mood, but sleep and appetite as well.
Lose Weight
Tomatoes can help you lose weight. If you are on a sensible diet and excercise plan, build lots of tomatoes into your everyday eating. They make a great snack and can be used to "bulk up" salads, casseroles, sandwiches and other meals. Because tomatoes contain lots of water and fiber that will fills you upfast without adding a lot of calories or fat.
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.
