Watermelon
Citrulline, a form of amino acid in watermelon, can be effective in controlling high blood pressure. This substance plays a role in the production of nitric oxide, which can relax blood vessels and improve the flexibility of the arteries. Both effects can improve blood flow and reduce blood pressure, especially in people with mild hypertension or prehypertension. To add watermelon to your diet, consider including it in smoothies or salads. You can also enjoy the fruit in a chilled soup. [10]
