Corn

One of the most widely consumed gluten-free cereal grains worldwide is corn, often known as maize. One cup (149 grams) of sweet corn contains 4 grams of fiber and 5 grams of protein.

In addition to having a lot of fiber, corn has a lot of the plant pigments lutein and zeaxanthin, known as carotenoids, which are antioxidants. According to studies, lutein and zeaxanthin can improve eye health by lowering the risk of age-related macular degeneration and cataracts, two major diseases that cause vision loss in older people. According to one research, those who consume more carotenoids had a 43% reduced chance of developing age-related macular degeneration than people who consume less of them.
