title: [Nutritional study relative to proteins, energy, and calcium in children eating school meals].
abstract: Food consumption and nutritional status were evaluated on 419 children having meals at school located in the surrounding of Santa Fe (Argentina). The protein, energy and calcium content of the meals were analyzed. Anthropometrical evaluation was made by the following indicators: weight to age, height to age and weight to height. Biochemical evaluation to a sample of the children, was made by urea/creatinine and calcium/creatinine indicators. Recommended protein consumption is achieved but a biological efficiency loss is detected, probably due to an insufficient energy intake. School meals provide about 50% of the daily energy requirements. Regarding calcium consumption, the dinner cover about 15% of the recommendations but they achieve 47-49% with the cup of milk. As in the case of energy, the calcium daily intake is insufficient as we can see by the calcium/creatinine indicator which shows that a 60% of the people are below of the normal values. All these results suggest that is necessary to increase the energy intake and calcium consumption to improve the nutritional status.
