Infantile colic, and what not to eat, depends on the cause of the colic. First, it is necessary to understand that infant colic is due to the immature development of the gastrointestinal function in infants. If some foods are not fully digested and absorbed, it can lead to increased accumulation of gas in the gut, thereby stimulating the nerves of the intestinal mucosa and causing colic. For such infants, it is best to avoid spicy, stimulating, and indigestible foods in the diet, such as potatoes, sweet potatoes, corn, etc. These foods are not easily digested and tend to produce gas. Additionally, it is important to avoid overeating, which can overburden the stomach and intestines, leading to symptoms of indigestion. Therefore, for symptoms of colic, the main approach is to control the diet, eat smaller, more frequent meals, and avoid overeating, which can worsen the burden on the stomach and intestines and exacerbate the symptoms.
