老年工人膳食钙磷来源和分布

Source and Distribution of Dietetic Calcium and Phosphorus in old Workers

对沈阳市皇姑区老年男女工人进行钙磷摄入量及其来源分布的调查分析。结果表明,本组人群钙的摄入水平较低,且主要来自豆类和蔬菜。男女两组人群来自于豆类的钙分别占摄入总钙量的25.4％和21.9％,来自蔬菜的钙男女分别占总摄入量的23.7％和25.0％。男女两组人群来自乳类的钙仅占21.8％和10.8％。磷的摄入虽然较高,但近50％来自于谷类和豆类。男女膳食Ca:P虽为1:1.96和1:2.17,但由于膳食中不可吸收磷较多,故该人群膳食未发生由于高磷而引起的钙吸收利用障碍。

63 old workers in Huariggu district of Shenyang were investigated for source and distribution of dietetic calcium and phosphorus. The results showed that the calcium intakes were low and mostly came from bean products and vegetables. The calcium from bean products accounted for 25. 4% and 21. 9% of the total calcium in the males and the females and they accounted for 23. 7% and 25. 0% from vegetables. Source of dairy products accounted for 21. &% and 10. B% in males and females. The phosphorus intakes were higher and 50% of them came from grain and bean products. Although the ratios of dietary calcium and phosphorus were 1 ?1. 96 and 1 ' 1. 27,calcium absorption disturbance due to excess phosphorus did not occur in the population because of more unabsorbable phosphorus.
