To validity, average nutrient intake from the three 24h dietary recalls were compared to average intakes from each FFQs (FFQ1 and FFQ2) by calculating Pearson correlation coefficients and adjusting for energy intake and within person variation. The nutrients were categorized into quartiles. The average intake was higher for deal of nutrients in the FFQ1 and FFQ2, when it was compared with average intake from the three IR24h. The average correlation coefficients intra-class was 0,63, while the average, considering, Spearman correlation was 0,62. To the validity, our founds was 0,41, the average of Pearson correlation to a FFQ1 and 0,46 to FFQ2. The average classification percentage in the same quartile for theen
