Watermelon health benefits and risk


Watermelon is a summertime staple, a beautiful and delicious fruit that is also really good for you

Benefits of Watermelon

Watermelon is a hydrating fruit with many possible health benefits. The nutrients in watermelon help support heart health, reduce muscle soreness, manage weight, aid digestion, and protect your skin. Watermelon may also prevent many chronic diseases

Keeps You Hydrated

Water isn't in the fruit's name by chance. One cup of watermelon contains approximately five ounces of water (about the size of a yogurt container).

Consuming adequate fluids—including water-rich foods—has 

  • Preventing dehydration
  • Regulating your body temperature
  • Lubricating your joints
  • Protecting your spinal cord
  • Moving waste out of your body (e.g., urinating, sweating, and having bowel movements)

Being properly hydrated also impacts mental performance. Research has found that as little as a 1% loss of body fluid can impair mood, reduce concentration, interfere with working memory, and boost anxiety several health benefits

Helps Lower Blood Pressure and Improves Circulation

L-citrulline is a natural substance in watermelon, particularly in the white part of the rind. L-citrulline may improve artery function and lower blood pressure by helping blood vessels relax and improving circulation. 

Some evidence suggests that L-citrulline may improve muscle oxygenation and athletic performance during endurance exercise

Might Reduce Muscle Soreness

In a study published in 2017, researchers asked people to drink 16 ounces of watermelon juice enriched in L-citrulline two hours before running a half-marathon. The researchers found that those who drank the watermelon juice had less muscle soreness for up to 72 hours compared to a placebo group

Helps Manage Weight

Watermelon may help manage weight when you consume it in place of a processed sweet snack.

A study published in 2019 looked at fullness and weight changes after a four-week intervention in overweight and obese adults. The researchers asked one group to consume two cups of fresh watermelon daily. A second group ate low-fat cookies with the same calories as the watermelon. 

The researchers allowed the groups to eat their snacks any time of day, during one or multiple sittings, or alone or with other foods. Watermelon promoted more fullness than the cookies, lasting up to 90 minutes after eating. People who ate watermelon lost weight, reduced their waist-to-hip ratios and blood pressure levels, and improved their cholesterol


Supports Digestion

Watermelon is not very high in fiber. Still, the fiber in watermelon helps support a healthy gut. The fruit contains fluid and prebiotics, a fiber that stimulates the growth and activity of "good" bacteria in the large intestine

Prebiotics are tied to healthy immune function, anti-inflammation, and positive mood Prebiotics also boost mineral absorption, improve blood sugar and insulin levels, and may protect against colon cancer

Helps Defend Against Chronic Diseases

Watermelon is one of the best sources of lycopene. Lycopene is an antioxidant known to combat oxidative stress caused by cell-damaging free radicals

As a result, lycopene helps reduces the risk of chronic diseases, including:

  • Heart disease
  • Type 2 diabetes
  • Cancer
  • Alzheimer's disease

For the most lycopene, opt for traditional pink flesh watermelon, which contains more antioxidants than yellow and orange varieties

  • Good source of fiber: Provides around 0.4 grams per 2/3 cup serving, aiding digestion and promoting gut health.
  • Rich in antioxidants: Contains vitamin C, lycopene, and other beneficial plant compounds that fight free radicals and may protect against chronic diseases.

Specific Nutrients and their Benefits:

  • Vitamin A (from beta-carotene): 5% of the DV per cup, contributing to healthy vision and skin.
  • Potassium: 4% of the DV per cup, helping regulate blood pressure and muscle function.
  • Citrulline: An amino acid that converts to L-arginine in the body, potentially improving blood flow and exercise performance.
  • Lycopene: A powerful antioxidant with potential benefits for heart health and prostate cancer prevention.


Risks of Watermelon

    • Digestive issues: Watermelon contains natural sugars and fiber, which can cause bloating, gas, and diarrhea in some people, especially if consumed in large quantities.


    • Blood sugar spikes: While not excessively high in sugar compared to other fruits, the combination of natural sugars and high water content can cause temporary blood sugar spikes in people with diabetes or prediabetes. It's best to enjoy watermelon in moderation and be mindful of portion sizes.


    • Allergic reactions: Although rare, some people may be allergic to watermelon, experiencing symptoms like hives, swelling, or trouble breathing. If you experience any allergic reactions, seek medical attention immediately.


Specific Concerns:



    • Potassium levels: High potassium levels in watermelon may interact with certain medications like potassium supplements or ACE inhibitors. If you have any concerns about potassium intake, consult your doctor.


  • Foodborne illness: Like any other produce, watermelon can harbor harmful bacteria if not handled properly. Wash it thoroughly before consumption to minimize the risk of contamination
