Watermelon and watermelon juice have the following health benefits: Heart, blood pressure, blood flow, weight loss, kidney and antioxidant properties.
Good for the heart, good for blood
Citrulline is abundant in watermelon, which can restore blood pressure to normal levels by dilating the artery walls. Blood can move more smoothly through these dilated arteries, allowing the heart to consume less energy to pump blood through the body while maintaining a steady flow.
In addition, watermelon has a high content of vitamin C and beta-carotene that lowers blood cholesterol. It also has lycopene and other phytochemicals, and powerful antioxidants that help fight heart disease.
Watermelon juice provides magnesium and potassium to the body, ensuring healthy blood vessels. These two nutrients maintain the proper balance of acids and electrolytes, helping to stabilize blood pressure and blood flow. Potassium also helps to clear salts and toxins from the body by acting as a diuretic.
Blood, muscle and body weight benefit from the amino acids in watermelon. The citrulline in watermelon rind is converted into an essential amino acid called arginine. This amino acid helps regulate blood flow and dilates blood vessels.
The smooth movement of the blood brings more energy to the tissues and organs to work actively, thereby reducing stress. Arginine also relieves muscle soreness after intense physical activity.
Weight loss
Additionally, animal tests have shown that citrulline can prevent fat from building up in cells, possibly preventing excessive weight gain and obesity. Watermelon juice is low in calories but has the potential to be filling. Drinking a glass before a meal can help curb your appetite, which in turn helps you lose weight.
Anti-aging and anti-oxidation
Lastly, many of the antioxidants in watermelon work to eliminate free radicals in the body. By eliminating these dangerous chemicals, antioxidants can prevent the onset of arthritis, asthma, cancer, stroke and many other related diseases.
Premature aging is also linked to free radical activity. So, a glass of watermelon juice rich in antioxidants can help restore a youthful and smooth look to your skin while purifying your body.
