This fruit is rich in vitamin C, which is essential for our immune system. 3. Improves bone health. Watermelon contains lycopene, which is especially important for our bone health. 4. Improves cardiovascular health. Consuming watermelon in large quantities, according to many studies, positively correlates with improved cardiovascular function, as it increases blood flow through vasodilation. 5. Helps to lose body fat. Watermelon contains citrulline, which helps reduce fat accumulation in our fat cells. 6. Improves eye health. This fruit is a great source of beta-carotene (hence the reddish color of its interior) that converts to vitamin A. It helps produce pigments in the eye retina and protects against age-related macular degeneration. 7. Diuretic effect. Watermelon is a natural diuretic that helps increase urine flow and protect the kidneys. 8. Anti-inflammatory and antioxidant. Watermelon is rich in phenolic compounds such as flavonoids, carotenoids, and triterpenoids.
