Nutrient adequacy of low fat intakes for children: the Bogalusa Heart Study.

Nutritional adequacy is important when diets and dietary alterations are recommended for children. Concern is expressed that low fat intakes may have deleterious effects on growth and development and may be deficient in total calories and essential nutrients. In a study of the effect of variation in percent fat in the diet, a sample of 871 ten-year-olds was stratified according to four different fat intakes: less than 30% of total kilocalories (kcal), 30% to 35% kcal, 35% to 40% kcal, and greater than 40% kcal. The race/sex distribution was similar within each fat intake group. Fourteen percent of the sample had fat intakes less than 30% of total calories. The amount of calories from breakfast, dinner, and snacks was higher in the children with fat intakes greater than 40% of total calories than those with lower fat intakes. The energy intake of all race/sex groups fell within the recommended range. The low fat intake group was eating 25% less calories than the high fat intake group (1800 kcal vs 2400 kcal). The percentage of calories from carbohydrate, specifically sugar, was greater in the low fat intake group compared with the high fat intake group. Percentage of calories from protein was approximately 13% for all groups. Fiber and starch were the same across all fat intakes.(ABSTRACT TRUNCATED AT 250 WORDS)
