NEWS YOU CAN USE: Watermelon prevents sore muscles.

If you eat a couple of large chunks of watermelon before a heavy training session today, you’ll have less problems with sore muscles tomorrow. According to nutritionists at the Universidad Politecnica de Cartagena in Spain, this is because watermelon is a high-quality source of L-citrulline . . .

L-Citrulline is a precursor of L-arginine, which in turn is a precursor of the blood vessel widener and performance enhancer nitrogen monoxide.
