Here are five health benefits of watermelon that you may not know about:

2. Heart health: Watermelon contains an amino acid called citrulline that has been shown to improve blood flow and reduce blood pressure. Additionally, the fruit is rich in potassium, a mineral that helps regulate heart function and prevent heart disease.

3. Anti-inflammatory: Watermelon contains lycopene, a powerful antioxidant that has been shown to reduce inflammation in the body. Chronic inflammation is linked to many health problems, including arthritis, heart disease, and cancer.
