Watermelon beats the scorching summer heat with 95% water and its electrolytes. It wards off unwanted pesticides with its think rind and harbours enormous vitamin A, lycopene and an antioxidant - glutathione preroxidase present at the red pulpy area close to the rind. The white rind which we commonly discard as tasteless contains Citrulline, an amino acid that produces the vasodilator - nitric oxide. The ability of citrulline to convert to L-arginine promotes heart health. It is worthy to note the edible watermelon seeds hide tryptophan, B vitamins and are relatively rich in proteins and lipids.
