Myth #3: Sweet corn is high in sugar
Fact: Yes, corn is sweet for a vegetable—but there are only 6 grams of natural sugar in a medium-size ear of corn. An ear of sweet corn has less than half the sugar of a banana and only about one-third the sugar of an apple. Even beets have more grams of sugar per serving than corn.
The high-sugar corn myth may be partly due to some long-standing confusion over corn varieties. High-fructose corn syrup, dextrose, glucose and other sweeteners are derived from field corn, the virtually inedible commodity crop used to make everything from livestock feed to ethanol. Those highly processed sweeteners are nothing like the natural sugars found in sweet corn, the vegetable you eat. Ditch the stuff with the chemical-sounding names, and stick to the real thing instead.
Myth #4: Corn has no health benefits
Fact: For starters, sweet corn is loaded with lutein and zeaxanthin, two phytochemicals that promote healthy vision. Besides helping with weight loss, the insoluble fiber in corn feeds good bacteria in your gut, which aids in digestion and helps keep you regular. Throw in a healthy amount of B vitamins, plus iron, protein and potassium, and you've got one sweet package.
Myth #5: The cooking process robs corn of its nutrients.
Fact: Cooking sweet corn actually boosts its benefits. In a Cornell study, researchers found that while sweet corn loses vitamin C during cooking, its antioxidant activity increases. Studies show eating foods high in antioxidants can help lower your risk of heart disease as well as Alzheimer's disease, cataracts and other health problems linked to aging. Cooked sweet corn also has a surprising amount of ferulic acid, a type of compound that helps fight cancer. Crank up the cooking temp and you'll increase the benefit even more.
