Yep, you read that right – watermelon RIND. It turns out that white part, next to the dark green outer layer of watermelons, is edible. It also has as much health benefits as the watermelon itself, so the next time you eat watermelons, think twice before throwing away the rind.
Here are the top benefits of eating watermelon rind:
#1: Fights free radicals
According to the Journal of the Science of Food and Agriculture, citrulline, which helps get rid of free radicals, has a huge concentration on watermelon rind. Citrulline is also converted to an amino acid that ultimately provides heart and immune system protection and keeps harmful toxins from residing in the body.
#2: Boosts libido
Researchers from Texas A&M’s Fruit and Vegetable Improvement Center have noted that citrulline helps blood vessels relax and can even help with erectile dysfunction. In fact, its ability to boost blood flow have led to watermelon’s citrulline to be referred to as “nature’s Viagra.”
#3: Helps in weight loss
Citrulline once again comes into play. Studies suggest that citrulline consumption leads to 30 percent less weight gain. The idea is that the citrulline in the rind leads to less muscle fatigue, which therefore allows people to extend the duration of their workouts and, in turn, better manage weight.
#4: Keeps prostate healthy
Watermelon rind is a great source of lycopene, an antioxidant that helps ward off prostate cancer. The diuretic properties of watermelons can also keep the urinary tract in healthy working order.
#5: Good for the skin
A 1-inch cube of watermelon rind contains 1.8 calories. The majority of the calories come from some carbohydrates, with 0.32 grams per serving. One serving provides 2 percent of the daily recommended vitamin C intake and 1 percent of the vitamin B-6 our body requires every day. This make water melon good for the skin and immunity, as well as the health of the nervous system.
