[Study on content and intake status of vegetable fiber in rural residents in China].
OBJECTIVE
To study the distribution and intake of vegetable fiber of Chinese rural residents.


METHODS
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.


RESULTS
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%.


CONCLUSIONS
The consumptions of vegetables, and its fiber and its monomer contents were unbalanced in different areas all over the country.
