Corn on the cob is a simple, beloved dish consisting of a whole ear of corn, typically boiled, steamed, or grilled, and often served with butter and salt. Its core ingredient is sweet corn, a variety of maize originally domesticated in Mesoamerica and now enjoyed globally as a staple and seasonal treat.
This dish is primarily a source of complex carbohydrates and dietary fiber, with a moderate amount of protein and very little fat. A single ear provides key nutrients like vitamin C, B vitamins (especially thiamine and folate), and minerals such as magnesium and phosphorus, with a typical serving containing roughly 100-120 calories.
Nutritionally, corn is unique as it contains antioxidant carotenoids like lutein and zeaxanthin, which are beneficial for eye health. Culturally, it holds deep significance as a foundational crop in the Americas and is celebrated in various festivals and culinary traditions worldwide.
