The objectives of this review were to investigate the status and characteristics of national grain consumption and dietary fiber intake among Chinese adults (aged ≥20 years) and to examine trends in consumption from 1982 to 2015. Data from 5 national surveys that collected dietary information using a household food weighing method and 24-hour dietary recall over 3 consecutive days were analyzed. In 2015, mean grain consumption was 281.1 g/per capita/d (rice 145.6 g, wheat flour 120.7 g, other grains 14.8 g). Total dietary fiber intake was 9.7 g/per capita/d, of which 3.8 g/per capita/d came from grains and accounted for nearly 40% of total dietary fiber intake for adults. The other major sources of dietary fiber were vegetables and fruits. The data indicates consumption of grains and dietary fiber in the Chinese population has been continuously declining since 1982 and the consumption of refined grains has increased. In order for the Chinese population to meet dietary recommendations for whole grain and dietary fiber intake, increasing the availability of more appealing whole grain products and public education are recommended.
本研究旨在调查中国成年人（年龄≥20 岁）的粮食消费和膳食纤维摄入现状和特点，并分析 1982 年至 2015 年的消费趋势。研究采用家庭称重法和连续 3 天 24 小时膳食回顾法收集膳食信息，对 5 次全国性调查的数据进行了分析。2015 年，人均粮食消费量为 281.1 克/人/天（大米 145.6 克，小麦粉 120.7 克，其他谷物 14.8 克）。膳食纤维总摄入量为 9.7 克/人/天，其中 3.8 克/人/天来自谷物，占成年人膳食纤维总摄入量的近 40%。膳食纤维的其他主要来源是蔬菜和水果。数据表明，自 1982 年以来，中国人均粮食和膳食纤维摄入量持续下降，精制谷物摄入量增加。为了使中国人均达到全谷物和膳食纤维摄入的膳食推荐量，建议增加更受欢迎的全谷物产品的供应，并开展公众教育。
