Drinking water is an important way to keep your body hydrated. However, eating foods with high moisture content can also help. Interestingly, watermelon is 92% water. High water content is one of the reasons why fruits and vegetables help you feel full. The combination of water and fiber means that you are eating a lot of food without a lot of calories.
2. Contains compounds that help prevent cancer.
The researchers studied the anti-cancer effects of lycopene and other plant compounds. Although lycopene intake is associated with a low risk of some types of cancer, the results are mixed. So far, the relationship between lycopene and digestive system cancer seems to be the closest.
Lycopene seems to reduce cancer risk by lowering insulin-like growth factor (IGF), a protein involved in cell division. High IGF level is associated with cancer. In addition, the ability of cucurbitacin E to inhibit tumor growth was also studied.
3. May improve heart health
Heart disease is the leading cause of death in the world. Lifestyle factors, including diet, can reduce the risk of heart attack and stroke by lowering blood pressure and cholesterol levels. Several nutrients in watermelon have special benefits for heart health.
Studies have shown that lycopene helps to lower cholesterol and blood pressure. It can also help prevent oxidative damage of cholesterol. According to the study of obese postmenopausal women and Finnish men, lycopene may also help to reduce the hardness and thickness of arterial wall.
Watermelon also contains citrulline, which may increase the content of nitric oxide in the body. Nitric oxide can help your blood vessels dilate, thus lowering blood pressure. Other vitamins and minerals in watermelon are also good for your heart. These include vitamins A, B6, vitamin C, magnesium and potassium.
It may help to prevent macular degeneration.
Lycopene exists in many parts of the eyes, which helps to prevent oxidative damage and inflammation. It may also help prevent age-related macular degeneration. This is a common eye problem that may lead to blindness in the elderly. As an antioxidant and anti-inflammatory compound, lycopene may help prevent the development and deterioration of AMD.
