The new book "Juice," by the founders of Los Angeles' Pressed Juicery, includes this helpful tip: Don't throw away watermelon rinds -- juice them instead! Watermelon rind contains a compound that produces antioxidants and anti-fungal properties. As a plus, watermelon rind juice is delicious. Just run it through an electric juicer and add a squeeze of lime. The mild-tasting juice can be consumed alone or as part of your own homemade juicing recipe. According to "Juice," watermelon rind is even believed to be the wellness world's natural answer to Viagra.
