I love watermelon, how about you? Not only is it the official fruit of summer but watermelon is loaded with citrulline, an amino acid that has been shown to lower blood pressure and also increase strength. Watermelon is also a good source of protein and carbs! Watermelon is so much more better than cake for desert and makes a great pick me up snack in the afternoon. Pack it in your lunch and even take it on a picnic.
