RESUMO
Dietary fiber has important health benefits in adolescence, especially in promoting normal laxation and reducing the future risk of some chronic diseases. The purpose of this survey was to examine the dietary fiber intake among Costa Rican adolescents. Prospective 3-d diet records were used for dietary fiber data collection. The "age + 5 rule" was used as criterion for adequate fiber intake. Mean daily reported fiber intake was 23.8 +/- 12.6 grams. Mean fiber intake was higher in rural areas than in urban areas either for direct intake data or for values adjusted per 1,000 Kcal (13.6 +/- 7.7 and 8.2 +/- 2.9 respectively, p < 0.001). On the contrary, no differences were found among males and females when mean fiber intake was adjusted per 1,000 kcal. On average, only 45 of the total adolescents studied showed an adequate fiber intake. This percentage was higher in rural areas than urban areas. Adolescents who met the "age + 5 rule" have healthier diets than those with inadequate fiber intake. This study suggests that nutritionists working with adolescents should focus their efforts on promoting the consumption of fiber-rich foods, especially legumes, fruit and vegetables, in order to reduce the risk of diet-related chronic diseases during adulthood.
