To study the distribution and intake of vegetable fiber of Chinese rural residents.
The vegetable fiber content data were come from the datumbase of ecological survey in 65 Chinese counties in 1983. All food data were grouped under eight areas according to Chinese "Eleven-Five" Programming of State Council. Average value, standard deviation and variances analysis were used to evaluate the distribution of dietary fiber content in vegetables.
The consumptions of vegetables in different areas were unbalanced. Radish, kidney bean, eggplant, red pepper, pumpkin, radish leaf, rape, Chinese cabbage, common cabbage, Chinese celery, Chinese leek were widely taken in all area of China, while other vegetables were partly taken in the part area of China. The content distributions of dietary fiber and/or its monomer were also unbalanced. There were statistically significant differences of vegetable fiber and/or its monomer contents in radish, kidney bean, red pepper, pumpkin, common cabbage, sweet potato leaf, spinach, and Chinese leek among the part area of China (P < 0.01, P < 0.05). When the vegetable fiber data were used to evaluate its intake of a rural standard person from vegetables in the national survey of nutrition in 1982, 1992 and 2002, the percentage of its intake to AI were respectively 32.7%, 32.2% and 29.7%.
The consumptions of vegetables, and its fiber and its monomer contents were unbalanced in different areas all over the country.
研究中国农村居民蔬菜纤维的分布及摄入量。
蔬菜纤维含量数据来自1983年中国65个县的生态调查数据库。所有食物数据根据国务院“十一五”规划分为八个区域。采用平均值、标准差和方差分析来评估蔬菜中膳食纤维含量的分布情况。
不同地区的蔬菜消费量不均衡。萝卜、芸豆、茄子、红椒、南瓜、萝卜叶、油菜、大白菜、小白菜、芹菜、韭菜在中国所有地区均广泛食用，而其他蔬菜仅在部分地区食用。膳食纤维及其单体的含量分布也不均衡。中国部分地区的萝卜、芸豆、红椒、南瓜、小白菜、甘薯叶、菠菜和韭菜中的蔬菜纤维及其单体含量存在统计学显著差异（P < 0.01，P < 0.05）。当用蔬菜纤维数据评估1982年、1992年和2002年全国营养调查中农村标准人从蔬菜中的摄入量时，其摄入量占适宜摄入量（AI）的百分比分别为32.7%、32.2%和29.7%。
全国不同地区的蔬菜消费量及其纤维和单体含量不均衡。
