Dietary assessment of a group of elderly Spanish people

Abstract

The dietary patterns of 60 elderly from Spain (37 women and 23 men) were examined by analysis of the food, energy and nutrient intake during 5 days. The caloric profile was somewhat unbalanced, since the percentage of total energy intake from proteins and lipids was above the recommended limit whereas the proportion of energy derived from carbohydrates was slightly deficient. The degree of underreporting derived by subtracting predicted total daily energy expenditure from self-reported energy intake obtained from a diet control during 5 days is 120kcal/day in men and 334kcal/day in women. More than 50% of the population showed intakes of pyridoxine, folates, vitamin A (only in men), vitamin D, vitamin E, zinc, magnesium and iron (only in women) lower than those recommended. Although it is likely that the real intakes of these micronutrients are higher than the levels measured considering the underreporting, the obtained results show the existence of a risk of deficiency of several nutrients. An increase in the energy intake of the group with a parallel increase in physical activity with a view to avoiding weight gain may be of use in improving the nutritional status of the group. This measure, together with increased consumption of vegetables and milk products especially, may lead to a striking reduction in illness, a finding that is of considerable clinical and public health importance.
