[Study on dietary pattern and nutrients intakes of residents in areas of high and low incidence of esophageal cancer].

The dietary pattern and nutrients intakes of residents in areas with high and low prevalence of esophageal cancer were studied by 3 days' dietary survey. The results showed that the dietary pattern and nutrients intakes of residents in areas with low prevalence (ALP) of esophageal cancer was superior to that in area with high prevalence (AHP). The amount of soybean, meat and vegetable consumed by residents in the ALP was more than that in the AHP. Deep color vegetable and gaelic vegetable were dominant in ALP, but so were light color vegetables in AHP. The protein quality and quantity as well as the amount of Zn, Ca, RE and riboflavin consumed in the AHP were lower than that in the ALP. The energy from carbohydrate accounts for 78.14% of the total in the AHP. It is suggested that poor dietary pattern and the quality and amount of nutrients intake may be related to the development of esophageal cancer, and nutrition intervention in area of high prevalence seems rational.
