The food intake of two samples of children born five years apart were determined in 1975 and 1980 at three years of age in a low and middle class neighbourhood of Jerusalem. The 24-hour recall method was used. No deficiency in caloric intake was noted. The protein intake was twice the recommended dietary allowance (RDA), 3.7 gr/kg in the study group interviewed in 1975 and 3.3 gr/kg in those interviewed in 1980. The mean daily iron intake was only 40% of the RDA. The main sources for protein were milk and milk products, poultry and eggs. Significantly higher mean caloric and protein intakes were noted for the upper as compared to middle and low social class in 1980. Children from Asian origin had the lowest caloric and protein intake in 1975 and 1980 whereas those of European-American origin had the highest. Severe inflation and the resulting tenfold increase in food prices in Israel were not reflected in marked changes in dietary intake. The percentage expenditure on food was 25% of total income during both periods. The possible factors influencing the stability in dietary intake are governmental subsidy for the essential foods, correction of wages and increase in social security payments thus maintaining the buying power, as well as the educational effect of the preventive services--the Mother and Child Health Stations on feeding practices.
1975年和1980年，在耶路撒冷一个中低收入社区，对两组相隔五岁出生的儿童在三岁时的食物摄入量进行了测定。采用了24小时回顾法。未发现热量摄入不足。蛋白质摄入量是推荐膳食摄入量（RDA）的两倍，1975年接受访谈的研究组为3.7克/千克，1980年接受访谈的为3.3克/千克。每日铁摄入量平均仅为RDA的40%。蛋白质的主要来源是牛奶及奶制品、家禽和蛋类。1980年，与中低社会阶层相比，高社会阶层的热量和蛋白质平均摄入量显著更高。1975年和1980年，亚洲裔儿童的热量和蛋白质摄入量最低，而欧美裔儿童的摄入量最高。以色列的严重通货膨胀以及由此导致的食品价格上涨十倍，并未在饮食摄入量上体现出明显变化。两个时期食品支出占总收入的比例均为25%。影响饮食摄入量稳定性的可能因素包括政府对基本食品的补贴、工资调整和社会保障金增加从而维持购买力，以及预防服务——母婴健康站对喂养方式的教育作用。
