The aim of the present study was to investigate the difference of intolerance to food between southern and northern middle-aged Chinese, and furthermore analyze its association with eating habits in both study population.
ELISA was applied to determine the serum concentrations of specific IgG of 14 food anaphylactogen in 1568 healthy subjects from totally 9 districts in both southern and northern China. Life style questionnaire was also applied to investigate the daily intake of six categorizes of food associated with food intolerance.
45.8% of all subjects were found to be intolerant to certain food. 62.3% of subjects from southern China and 40.4% of subjects from northern China were found to be intolerant to certain food, the difference between southern and northern Chinese was statistically significant. Top three foods intolerant by southern Chinese were crab, egg, and cold fish, while top three food intolerant by northern Chinese were egg, crab, and milk. The differences of intolerance to crab, cold fish, soy bean, rice, and tomato between southern and northern Chinese were statistically significant. Investigation on eating habits revealed that cereals and fish were the major food consumed by subjects in our study. There was no certain association between food intolerance and eating habits.
Considering that there are differences between southern and northern Chinese, southern and northern Chinese should pay attention to their daily food in order to avoid food allergy.
本研究旨在调查中国南方和北方中年人群食物不耐受情况的差异，并进一步分析其与研究人群饮食习惯的关联。
采用酶联免疫吸附测定法（ELISA）检测来自中国南方和北方共9个地区的1568名健康受试者血清中14种食物过敏原特异性IgG的浓度。同时应用生活方式问卷调查与食物不耐受相关的六类食物的每日摄入量。
发现45.8%的受试者对某些食物不耐受。南方受试者中62.3%对某些食物不耐受，北方受试者中40.4%对某些食物不耐受，南方和北方人群之间的差异具有统计学意义。南方人不耐受的前三种食物是螃蟹、鸡蛋和冷鱼，而北方人不耐受的前三种食物是鸡蛋、螃蟹和牛奶。南方和北方人群在对螃蟹、冷鱼、大豆、大米和西红柿的不耐受方面存在统计学显著差异。饮食习惯调查显示，谷物和鱼类是本研究受试者的主要食物。食物不耐受与饮食习惯之间没有特定关联。
鉴于中国南方和北方人群存在差异，南方人和北方人应关注日常饮食以避免食物过敏。
