 In this research we studied 1) the effect of flavor enhancement of food on liking and/or food intake in elderly people by adding MSG and/or flavors to their hot meal and 2) the relationship between elderly people with an altered taste and/or smell performance and liking and intake of flavor-enhanced foods using tomato soup with MSG and celery powder. The results show that flavor enhancement did not increase liking and energy intake of the hot meal and elderly with an impaired taste and/or smell functioning did not show an increase in liking and intake of the flavor-enhanced soup. In conclusion, a standardized flavor enhancement of foods did not prove an effective approach to increase food intake in frail elderly people. Since elderly are a heterogeneous group we suggest a more individual, tailored taste and/or flavor enhancement of foods as part of a treatment or used in the prevention of undernutrition.
