5. Watermelon Reduces Inflammation and Oxidative Stress
Inflammation is a major cause of many chronic diseases. Watermelon can help reduce inflammation and oxidative damage, as it is rich in the anti-inflammatory antioxidants lycopene and vitamin C.
In one study in humans who supplemented with lycopene-rich tomato juice along with vitamin C, their inflammatory markers were reduced and antioxidant levels increased. Watermelon is rich in both lycopene and vitamin C. As an antioxidant, lycopene may also benefit brain health. For example, it may help delay the onset and progression of Alzheimer's disease.
