Vitamin c intake and biochemical status in 25 children of a school in Perugia.
In 25 schoolchildren (7-15 years old) a survey has been carried out in spring and fall on vitamin C intake by chemical analysis and plasma level of ascorbic acid. The inter-variation in the intake was very great and correspondingly the standard deviation was large. The values obtained by computation with food composition tables agreed with those by chemical analysis. There was no correlation between plasma ascorbic acid and vitamin C intake expressed also per kg body weight. But the values obtained with this study, together with those of other studies, indicate that in children a higher intake of vitamin C is necessary than in adults to achieve a certain plasma ascorbic acid concentration.
