['Several studies have shown that malnutrition is common among nursing home residents.', 'We hypothesized that addition of natural energy-dense ingredients to a standard diet would improve voluntary energy intake and ability to perform activities of daily living (ADL) and decrease infections in elderly residents under nursing home care.', 'Thirty-five residents in a municipality nursing home (median age 83 years) were served either a standard diet (1600 kcal/day) (control group, n=18) or the same meals fortified with natural energy-dense ingredients (2100 kcal/day) (experimental group, n=17). Energy intake and ADL function were measured before and after the intervention. All episodes of infection were registered. Non-parametric statistics were used.', 'Energy intake increased in the experimental group from 23.5 (21.3-28.5) kcal/kg/body weight before, to 31.9 (29.7-33.7) kcal/kg/body weight during the intervention (P<0.001). There was no change in energy intake in the control group. ADL function in the experimental group was unchanged, while it decreased significantly in the control group (P<0.001). The number of infections tended to be lower in the experimental group than in the control group (5 vs 13). The cost for the energy-dense ingredients was approx. 0.11 EUR per resident and day.'] Do energy-dense meals improve energy intake in elderly residents in a nursing home?
