Wellness
One medium ear has about 2.5 g of fiber (9% DV). Fiber, especially the insoluble kind, helps food move through the digestive system. (USDA · Harvard) Sweet corn is one of the starchier vegetables, with about 22 g of carbohydrate per ear. In long-term studies cited by Harvard's Nutrition Source, starchier vegetables like corn, potatoes and peas were linked with weight gain, while foods like berries, apples and pears were linked with weight loss.

Pick, store and use
- Pick
Choose ears with plump, tender kernels and no bugs or damage. (MSU Extension)
- Store
Keep corn in its husk in the fridge, and don't wash it until you're ready to cook. Eat or preserve it within 2–6 hours of picking for the best quality. (MSU Extension)
- Use
To freeze kernels, boil husked ears for 4 minutes, cool in ice water for 4 minutes, then cut the kernels off. Only pressure-can corn; it isn't safe to can any other way. (MSU Extension)
