Diet information based on the Nationwide Food Consumption Survey of 37,785 individuals in 22 age-sex groups was analyzed for food energy and nutrient intakes. The purposes were to identify nutritional problems of high or low intakes, those population groups at risk nutritionally, and the sources of nutrients consumed. Some of the results were: intakes of calcium, iron, magnesium and vitamin B6 were below 70% of RDAs for at least 33% of the individuals across several age-sex groups; intakes of vitamins A and C were below 70% of RDAs for more than 25%; intakes most often below the RDA were calcium and magnesium of females over 12, iron of 1-2 year olds and 12-50 year old females, and vitamin B6 of females over 12 and males over 64. Analysis of nutrient food sources generally revealed significant differences between highest and lowest intake levels of each nutrient. Calcium in the highest intakes came from the milk group (67%), while the proportion changed in the lowest intakes to only 35% from the milk group. Vitamin B6 in the highest intakes came equally from meats, grains, and vegetables, but in the lowest intakes it came primarily from meats and eggs. Vitamin C sources varied from citrus fruits in the highest intakes to vegetables (mainly potatoes) in the lowest intakes. (cj).
