Wellness
A cup of diced watermelon has about 46 calories, plus 12 mg of vitamin C (14% DV). That makes it a good source of vitamin C. (USDA) The NIH Office of Dietary Supplements says the body needs vitamin C to make collagen, which helps wounds heal, and that vitamin C improves absorption of iron from plant foods and helps the immune system work properly.

Pick, store and use
- Pick
Choose one with a hard rind that feels heavy for its size, with a yellow patch on the “belly” where it sat on the ground. Thumping doesn't tell you if it's ripe. (MSU Extension)
- Store
Uncut watermelons keep up to 2 weeks at 45–50°F. Wrap cut pieces tightly and refrigerate; they last up to 3 days. (MSU Extension)
- Use
Rinse or scrub the rind under cool running water before cutting. (MSU Extension)
