On a hot summer day, a slice of cold watermelon can be wonderful. But watermelon is more than just a cool, refreshing treat. Watermelon contains high levels of nutrients that make it a valuable addition to any diet.
Water
The average watermelon is 91 percent water. Water helps flush toxins from the body and carry nutrients to cells, according to the Mayo Clinic. A lack of water can lead to dehydration. Symptoms of dehydration include lethargy, low urine output, low blood pressure and rapid heart rate.
LYCOPENE
This is an antioxidant compound that “has been associated with reduced cancer risk, [especially] lung, cervix, bladder, prostate and skin,” said Brian K. Jones, registered dietitian at Memorial Hospital. According to cancer.org, the website for the American Cancer Society, lycopene also has been associated with lowering risk of heart disease and macular degeneration, and with reducing low-density lipid (so-called “bad” cholesterol).
POTASSIUM
According to the National Center for Biotechnology Information, potassium aids in the proper functioning of heart, kidneys, muscles, nerves and digestive system. “Potassium is one of our main electrolytes, so it helps with fluid balance issues within our body,” Jones said. “Without potassium, you can’t regulate hydration.”
VITAMIN A
Vitamin A is an essential part of a healthy immune system and might, according to the Office of Dietary Supplements at the National Institutes of Health, help lymphocytes fight infections more effectively. According to the institute: “Vitamin A promotes healthy surface linings of the eyes and the respiratory, urinary and intestinal tracts, as well as the skin.”
VITAMIN B6
Vitamin B6 is necessary to create hemoglobin, which helps to oxygenate the blood. It also helps to maintain blood glucose, according to the Office of Dietary Supplements at NIH. It helps to break down proteins and regulate normal nerve function. According to the Mayo Clinic, vitamin B6 plays a role in neurotransmitter synthesis, including that of serotonin.
VITAMIN C
Vitamin C is an antioxidant, helping to fight cancer-causing free radicals. It also helps to produce collagen, which is essential for healthy skin and bone development, according to the University of Maryland Medical Center. Vitamin C may help to reduce the risk of high blood pressure and stroke.
FIBER
Fiber is a valuable part of any weight-loss diet. Foods high in fiber provide a feeling of fullness, allowing a longer period of satiation. It also helps regulate bowel activity. According to an article from the Harvard University School of Public Health, fiber has been associated with reducing the risk of heart disease, diverticulitis and diabetes.
