Daily intake of macronutrients in a group of institutionalized elderly people in León. Spain

Monitoring of energy distribution of the three macronutrients of diet could be beneficial in order to improve the physiological status of elderly people. The objective of this study is to analyse total daily energy intake as well as the caloric contribution of the macronutrients and alcohol, which make up basic diet of five nursing homes in León (Spain). Dietary consumption was evaluated in a group of 107 elderly people, aged 65-98 years. A precise weighing method was used to conduct the control of food intake covering seven days. Protein, carbohydrates, fat, alcohol, dietary fiber and cholesterol intake were obtained. Weight, and Height also were measured. Total dietary energy intake was significantly higher in men (130.5%) than in women (115.6%), with regard to recommended value. Relative contribution of macronutrients to total energy intake is extremely unbalanced. Energy derived from protein was very high (16.7%), energy derived from fat was also very high, and significantly higher for females (39.6%) than for males (34.4%), whereas the proportion derived from carbohydrates was very low, although also significantly higher in females (41.5%) than in males (35.8%), due to the high energy percentage that make up the alcohol intake in males (9.1%). A review of the diet offered by nursing homes, not only directed at the adjustment of total energy intake but also with respect to alcohol intake and macronutrient content of foodstuffs used in the elaboration of the menus, would be required in order not to unbalance the caloric profile of the diet.
