Assessment of dietary adequacy for an elderly population based on a Mediterranean model.
This study analysed whether at different energy levels, a varied diet based on Mediterranean Diet patterns would meet the RDIs for specific nutrients in a population > 65 y. Based on RDIs for elderly persons > 65 y for PRO, FAT CHO, phosphorus, calcium, magnesium, iron, zinc, vitamin C, B6, folate and fibre, menu models based on Mediterranean diet food patterns were calculated for the following calorie levels: 1400, 1500, 1600, 1700 and 1800 kcals. 15 menu variations for each calorie level were then created based on the previously calculated models. Utilising the Program for Alimentation and Nutrition (PAN) database, nutritional analysis was carried out for all menus and the mean nutrient values for a 2 week period were calculated for each calorie level. Intakes at all calorie levels provided adequate amounts of folate, phosphorus, iron and Vitamin B6. Intakes were low in all groups for Calcium, Zinc, Magnesium and Vitamin E, with the exception of the 1800 kcal level for Vitamin E. Results show that at low energy levels, meeting nutrient needs was difficult and that even at higher calorie intakes, contrary to what was expected, certain nutrients were found to be inadequate.
