本文报告９０年代初北京市郊区５１０名年龄在３５～７４岁农民膳食调查结果。调查表明，农民的总热量及碳水化合物、蛋白质和脂肪三大营养素占总产热百分比尚较合理，但膳食中动物蛋白质约占总蛋白质摄入的１１％。农民摄盐量偏高，而钙摄入量不足。１０年来，膳食结构变化趋势显示，农民摄入脂肪酸中多不饱和脂肪酸与饱和脂肪酸的比值（Ｐ／Ｓ）从０．３７：１上升至１．７０：１，但人群胆固醇摄入量在８０年代后期显著增加。对于在北京市郊区农村开展心、脑血管病预防，应建议农民在经济发展的同时，一方面注意保持传统膳食结构，另一方面提倡低盐饮食，并鼓励适当增加牛奶及动物类食物的消费，以提高膳食中动物蛋白质占总蛋白质的比例，以及增加农民的钙摄入量。
This article reports the results of a survey of 510 farmers aged 35-74 in the suburbs of Beijing in the early 1990s. The survey shows that the total calorie of farmers and the three major nutrients of carbohydrate, protein and fat make up a reasonable percentage of the total caloric output, but animal protein in the diet accounts for about 11% of the total protein intake. Farmers have high salt intake and insufficient calcium intake. In the past 10 years, the trend of dietary structure showed that the ratio of PUFA to saturated fatty acid (P / S) of farmer’s fatty acid increased from 0.37: 1 to 1.70: 1, but the crowd’s cholesterol intake was 80 Significantly increased in later period. For the prevention of cardiovascular and cerebrovascular diseases in rural areas in the suburbs of Beijing, farmers should be advised to pay attention to keeping the traditional dietary structure while promoting low-salt diet while encouraging their economic development. Encourage the appropriate increase in the consumption of milk and animal foods To increase the ratio of animal protein to total protein in the diet and to increase farmers’ calcium intake.
