Nutritional assessments of 3-day dietary records in National Institute for Longevity Sciences--Longitudinal Study of Aging (NILS-LSA).

Food and nutrient intake of NILS-LSA participants 40 to 79 years of age were assessed through 3-day weighed dietary records by gender and age. The results were as follows. The intake of fats and oils, meats and beverages tended to decrease, but fruits increased with age in both males and females. Regarding nutrient intake, energy, protein, fat, and cholesterol showed a decrease as individuals aged. The nutrient intake in the 70 to 79 yr group was significantly lower than other age groups of both genders. The total dietary fiber and vitamin C intake increased. Salt intake exceeded 10 g/day in every group. The percentage of energy from fat to total energy was higher than 25% in most age groups. The proportion of fatty acids was almost appropriate in all groups.
