Watermelon Health Benefits
Research shows that eating watermelon can promote heart health, aid digestion, boost immunity, enhance workout recovery, and more. The potential health benefits come from its nutritional content.
Improves Heart Health
The citrulline in watermelon can help manage high blood pressure by relaxing blood vessels. Lycopene and other antioxidants help protect against LDL cholesterol oxidation linked to heart disease. The potassium supports healthy blood pressure levels too.
May Prevent Macular Degeneration
Lutein and zeaxanthin found in watermelon may help reduce risk of age-related macular degeneration (AMD). Their antioxidant and anti-inflammatory properties protect the eyes from damaging UV light exposure.
Boosts Immune System
Watermelon has nearly a third of the vitamin C you need daily, an antioxidant that stimulates white blood cell production for immune defense. It also has vitamin A for immune support and lycopene with potential anti-cancer activity.
Aids Digestion
The water and fiber in watermelon can promote digestive regularity and relieve constipation. Citrulline helps maintain the mucosal lining integrity in the GI tract. It may also reduce stomach ulcer risk.
May Lower Inflammation
Choline in watermelon helps regulate inflammatory responses. The anti-inflammatory abilities of lycopene and cucurbitacin E can also lower inflammation linked to some chronic diseases and arthritis pain.
Reduces Muscle Soreness
Consuming watermelon or watermelon juice before and after exercise helps speed up recovery and diminish muscle soreness thanks to its antioxidants, inflammation modulation, carbohydrates, and citrulline content.
Selecting and Cutting Watermelon
Picking a Watermelon
Choose a watermelon that:
- Feels heavy for its size
- Has a cream or yellow/orange underside
- Has a hard rind without cuts or dents
- Makes a hollow thump sound when tapped
Cutting a Watermelon
Steps to cut a watermelon:
- Place watermelon on a cutting board
- Cut a small slice off one end to create a flat base
- Turn watermelon and trim the opposite end
- Cut down the center along its longest length
- Cut each half down the middle to create quarters
- Slice each quarter width-wise for triangles, cubes or balls
Discard the white rind and cut the red flesh as desired. Cubes work well for fruit salads and skewers. Melon ballers easily make melon balls.
Watermelon Uses
Watermelon's sweet flavor, juice, and hydration making it perfect for:
Snacking and Salads
Enjoy fresh watermelon in slices, cubes, balls, or wedges on its own. Mix it into fruit salads, green or grain-based salads for a juicy sweetness.
Smoothies and Drinks
Blend it into smoothies like watermelon strawberry or watermelon banana smoothies. Use it in fruit infused water or juices. Watermelon goes well with lemonade or cocktails too.
Desserts
Sweet chilled watermelon makes a simple dessert. But it also shines in sorbets, fruit skewers, tarts, cakes and other desserts that use its sweetness and juice.
Side Dishes
Grill watermelon wedges as a sweet addition to any barbecue. You can also roast watermelon or add it to grain bowls, salsas and slaws to liven them up.
Potential Health Risks of Watermelon
Watermelon is safe for most people and associated with many health benefits. But some potential risks exist in overconsumption or contamination.
Allergic Reactions
Watermelons contain proteins that could potentially trigger allergic reactions in sensitive individuals, producing oral allergy syndrome symptoms like mouth and throat itching.
Pesticide Exposure
The thick rind protects the internal flesh, but trace amounts of pesticide residues can still be present on conventionally grown watermelons.
Citrulline Overdose
For individuals with kidney or liver disease, excess citrulline from high watermelon intake could potentially cause toxic buildup. Moderation is key.
Digestive Upset
While watermelon flesh is easily digested, the fibrous rind can be hard to break down and irritate the GI tract if large amount are consumed. Eat only small amounts or stick to just the flesh.
Foodborne Illness
Pre-cut watermelon has increased risk of contamination with dangerous bacteria like Salmonella and Listeria leading to foodborne illness. Only consume freshly cut watermelon from reputable places.
The Best Ways to Store Watermelon
Refrigerating uncut watermelons prevents ripening and bacterial growth. Watermelon lasts around 2 weeks refrigerated. Once cut, leftover flesh should be sealed and refrigerated where it keeps for 3-4 days.
Freeze pureed watermelon or cubes in airtight containers to enjoy months later in smoothies, drinks, and desserts. Watermelon juice can also be frozen into ice pops for healthy hydrating snacks.
