Corn dregs can affect digestion and cause vitamin deficiencies when eaten over a long period of time. Corn dregs are the intermediate products that come out of the milling process with corn as the raw material. The nutrients in corn dregs include cellulose, protein, esters, starch and so on. The fiber contained in corn helps to promote gastrointestinal peristalsis, thus facilitating digestion. Eating it in moderation is good for the human body, but long-term consumption can affect the digestive function. In addition, when only corn dregs are used as food, vitamin deficiencies can occur, therefore, the daily diet should be diversified, not too single. In summary, although corn dregs have many benefits, they should be eaten in moderation, should not be consumed in large quantities over a long period of time, and should be avoided for those who are prone to allergies.
