Choosing corn and whole-grain corn products can lead to better gut health and help lower your chances of getting diseases like cancer, heart disease, and type 2 diabetes. The fiber in corn helps you stay full for longer between meals. It also feeds healthy bacteria in your digestive tract, which may help protect against colon cancer. Popcorn may also help prevent diverticulitis, a condition that causes pouches in the walls of your colon. In a large study, men who ate more popcorn had a lower risk of getting diverticular disease. Corn is rich in vitamin C, an antioxidant that helps protect your cells from damage and wards off diseases like cancer and heart disease. Yellow corn is a good source of the carotenoids lutein and zeaxanthin, which are good for eye health and help prevent the lens damage that leads to cataracts. Corn also has smaller amounts of vitamins B, E, and K, along with minerals like magnesium and potassium.
