Is the cooked corn in the supermarket healthy?

Junk food refers to food that is considered unhealthy or contains only a small amount of nutrients. Junk food generally only provides some calories without other nutrients, or provides more food than the human body needs to become redundant ingredients. Including frozen desserts, biscuits, ham, canned food, hamburgers, pizza, candy, soft drinks and so on. It can be clearly known that junk food refers to finished products, so it is not limited to the ingredients themselves, and special attention should be paid to other chemicals added to the processed ingredients themselves and the processing technology. Corn itself is not junk food, but healthy food. However, if corn is used to produce a certain food, such as adding hydrogenated oil, high-calorie sweeteners and high-temperature processing, then healthy ingredients will also become junk food.
