Objective:To investigate the common food intolerance of 90 children with chronic gastritis. Methods: Ninety children with chronic gastritis were treated in our hospital from June 2017 to June 2018. Fasting elbow venous blood was collected. The specific IgG antibody levels of eggs, wheat, milk, tomatoes, cod, chicken, beef, rice, soybean, crab, corn, mushroom, shrimp and pork were detected. Results: Among 90 patients, 82 (91.11%) were positive for food specific IgG. The incidence of egg intolerance was the highest (78.89%), followed by wheat (36.67%) and milk (24.44%).Chronic gastritis children in school age are more common. The positive rate of food intolerance in different age groups ranges from high to low:toddler's age and preschool age (100%) > school age (89.5%) > adolescence (87.5%). Statistical analysis was made on five kinds of food intolerance of patients in different age groups:eggs, wheat, milk, tomatoes and cod. It was found that only milk had statistical significance (P<0.05). There was no significant difference in tolerance to common food between different genders (P>0.05). Conclusion: Food intolerance in children with chronic gastritis is influenced by age and type of food. The main food intolerance is occurred in eggs, wheat and milk. Milk intolerance have differences among different age groups and it is higher in preschool age and adolescent children.
