Is Sweet Corn Gluten-free?

Sweet corn is abundantly available this time of year and can make a budget-friendly nutritious addition to summer meals. The sweet, juicy kernels are gluten-free and are rich in fiber, folate and antioxidants. One ear of sweet corn only provides about 100 calories.

Sweet corn is higher in sugar than field corn and is picked while still immature and in its milk stage. Interestingly, each ear of sweet corn typically has 800 kernels arranged in 16 rows, with one strand of silk for each kernel.

How to Choose Good Sweet Corn

Choose sweet corn with fresh-looking husks and plump kernels that are well developed. Avoid corn that is dented in or has dry looking kernels. Store sweet corn with the husks on in a sealed container or wrapped tightly in plastic wrap. Use sweet corn within a few days after purchasing for the best flavor.

What’s the Easiest Way to Cook Sweet Corn?

Sweet corn can be steamed, boiled, grilled or baked. Besides grilling sweet corn, the easiest way to cook sweet corn is to husk it, then wrap in a wet paper towel and microwave for about 2 minutes.

    Didn’t know corn was gluten-free. I guess I hadn’t thought about it. Thanks for the tip on microwaving corn! Do you recommend refrigerating corn to keep it a few days longer?
