The kernel of knowledge: unlocking the secrets of what is sweet corn

Sweet corn, also known as sugar corn, is a variety of maize (Zea mays) that has been bred specifically for its high sugar content. Unlike field corn, which is primarily used for animal feed and industrial purposes, sweet corn is cultivated for its sweet and tender kernels. It is a popular summer vegetable enjoyed fresh, canned, or frozen.

History and Origin

Sweet corn originated in Mesoamerica, where it was domesticated by indigenous peoples thousands of years ago. Early varieties of sweet corn had a low sugar content and were not as sweet as modern cultivars. Over time, through selective breeding, farmers developed sweeter and more tender varieties.

Nutritional Value
