How much the nutritional needs of seniors differ from those of younger adults?
Most nutritional requirements remain about the same, but energy needs decrease. People in the older age groups should choose foods with high nutrient density. Energy needs decrease with age because the lean body mass decreases and the overall level of activity usually decreases as well. Calorie needs to depend on activity level as well as on body weight and composition, so obviously, a person who is confined to bed needs less than a person who is mobile. The higher the lean body mass, the more a person can eat without gaining weight and the more likely he or she will be to get adequate supplies of nutrients from daily meals. The body needs about 1.5 times the basal energy expenditure per day. There is a 10%reduction in this caloric need between the age of 50 and 75 with an additional 10-15% reduction after 75, depending on individual activity.
