A medium-sized ear of corn provides more than 10% of our daily dietary fiber requirements. Rich dietary fiber can help the body to carry out a rapid metabolism function, but also can make a strong sense of satiety.
The same amount of corn is lower in calories than rice, contains natural rather than added sugar, and is high in fiber, which can help gastrointestinal digestion, and has more vitamins, so it is a good food worth eating more. However, there is a limit to what you eat, and the food that will not gain weight will make you fat if you eat too much, at least, it will not make you thin. It can only be said that relatively speaking, eating corn is much healthier than eating those high-calorie snacks, and it is not easy to gain weight.
Moreover, the large amount of natural vitamin E contained in fresh corn has the functions of promoting cell division, delaying cell aging, lowering serum cholesterol, preventing skin lesions, and reducing the symptoms of arteriosclerosis and brain function decline.
