摘要
儿童营养需求与成人不同,而其消化系统功能却还不成熟。本文对儿童消化系统中口腔、胃肠运动、消化酶发育生理特点进行总结,其特点包括胃内pH高、胃肠酶分泌量和活性低、胃排空和肠蠕动慢、肠屏障功能低下,为儿童保健、营养供应、儿童食品的开发及体外消化模型提供参考,并提出了未来的研究方向。
The requirements of nutrients for children are different from adults′,and the digestive functions in children are immature.In the present review,the progress on developmental physiology of children in digestive system related to oral,gastric motility,and enzymes secretions were summarized.The main features include a higher pH in gastric fluid,a lower enzymes output and activities in secretions in stomach and pancreas,a slower gastric empty rate and intestinal motility,and the immature of intestinal barrier than those in adults.This review aims to provide knowledge for health care,nutrients supply,development of food and in vitro digestive models for children,thereby proposing future directions in related fields.
