Top 9 Health Benefits of Eating Watermelon
Written by Kerri-Ann Jennings, MS, RD on August 9, 2018
Watermelon is a delicious and refreshing fruit that’s also good for you.

It contains only 46 calories per cup but is high in vitamin C, vitamin A and many healthy plant compounds.

Here are the top 9 health benefits of eating watermelon.

1. Helps You Hydrate
Drinking water is an important way to keep your body hydrated.

However, eating foods that have a high water content can also help. Interestingly, watermelon is 92% water (1Trusted Source).

What’s more, a high water content is one of the reasons why fruits and vegetables help you feel full.

The combination of water and fiber means you’re eating a good volume of food without a lot of calories.

SUMMARY
Watermelon has a high water content. This makes it hydrating and helps you feel full.
2. Contains Nutrients and Beneficial Plant Compounds
As far as fruits go, watermelon is one of the lowest in calories — only 46 calories per cup (154 grams). That’s lower than even low-sugar fruits such as berries (2).

One cup (154 grams) of watermelon has many other nutrients as well, including these vitamins and minerals:

Vitamin C: 21% of the Reference Daily Intake (RDI)
Vitamin A: 18% of the RDI
Potassium: 5% of the RDI
Magnesium: 4% of the RDI
Vitamins B1, B5 and B6: 3% of the RDI
Watermelon is also high in carotenoids, including beta-carotene and lycopene. Plus, it has citrulline, an important amino acid.

Here’s an overview of watermelon’s most important antioxidants:

Vitamin C
Vitamin C is an antioxidant that helps prevent cell damage from free radicals.

Carotenoids
Carotenoids are a class of plant compounds that includes alpha-carotene and beta-carotene, which your body converts to vitamin A.

Lycopene
Lycopene is a type of carotenoid that doesn’t change into vitamin A. This potent antioxidant gives a red color to plant foods such as tomatoes and watermelon and is linked to many health benefits.

Cucurbitacin E
Cucurbitacin E is a plant compound with antioxidant and anti-inflammatory effects. Bitter melon, a relative of watermelon, contains even more cucurbitacin E.

SUMMARY
Watermelon is a low-calorie fruit high in some nutrients, especially carotenoids, vitamin C and cucurbitacin E.

3. Contains Compounds That May Help Prevent Cancer
Researchers have studied lycopene and other individual plant compounds in watermelon for their anti-cancer effects.

Though lycopene intake is associated with a lower risk of some types of cancer, study results are mixed. The strongest link so far seems to be between lycopene and cancers of the digestive system (1Trusted Source).

It appears to reduce cancer risk by lowering insulin-like growth factor (IGF), a protein involved in cell division. High IGF levels are linked to cancer (3Trusted Source).

In addition, cucurbitacin E has been investigated for its ability to inhibit tumor growth (4Trusted Source, 5Trusted Source).

SUMMARY
Some compounds in watermelon, including cucurbitacin E and lycopene, have been studied for their potential to prevent cancer, though study results are mixed.
4. May Improve Heart Health
Heart disease is the number one cause of death worldwide (6Trusted Source).

Lifestyle factors, including diet, may lower your risk of heart attack and stroke by reducing blood pressure and cholesterol levels.

Several nutrients in watermelon have specific benefits for heart health.

Studies suggest that lycopene may help lower cholesterol and blood pressure. It can also help prevent oxidative damage to cholesterol (1Trusted Source).

According to studies in obese, postmenopausal women and Finnish men, lycopene may also reduce the stiffness and thickness of artery walls (7Trusted Source, 8Trusted Source).

Watermelon also contains citrulline, an amino acid that may increase nitric oxide levels in the body. Nitric oxide helps your blood vessels expand, which lowers blood pressure (9Trusted Source).

Other vitamins and minerals in watermelon are also good for your heart. These include vitamins A, B6, C, magnesium and potassium (1Trusted Source).

SUMMARY
Watermelon has several heart-healthy components, including lycopene, citrulline and other vitamins and minerals.

5. May Lower Inflammation and Oxidative Stress
Inflammation is a key driver of many chronic diseases.

Watermelon may help lower inflammation and oxidative damage, as it’s rich in the anti-inflammatory antioxidants lycopene and vitamin C (1Trusted Source).

In a 2015 study, lab rats were fed watermelon powder to supplement an unhealthy diet. Compared to the control group, they developed lower levels of the inflammatory marker C-reactive protein and less oxidative stress (10Trusted Source).

In an earlier study, humans were given lycopene-rich tomato juice with added vitamin C. Overall, their markers of inflammation went down and antioxidants went up. Watermelon has both lycopene and vitamin C (11Trusted Source).

As an antioxidant, lycopene may also benefit brain health. For example, it may help delay the onset and progression of Alzheimer’s disease (12).

SUMMARY
Lycopene and vitamin C are anti-inflammatory antioxidants found in watermelon. Inflammation is linked to many chronic diseases.
6. May Help Prevent Macular Degeneration
Lycopene is found in several parts of the eye where it helps protect against oxidative damage and inflammation.

It may also prevent age-related macular degeneration (AMD). This is a common eye problem that can cause blindness in older adults (1Trusted Source).

Lycopene’s role as an antioxidant and anti-inflammatory compound may help prevent AMD from developing and getting worse.

SUMMARY
Lycopene may help keep eyes healthy and protect against age-related macular degeneration (AMD) thanks to its antioxidant and anti-inflammatory properties.
