A team headed by sensory scientist Claire Sulmont-Rossé from the National Institute for Agricultural Research (INRA) in Dijon, France, investigated the sense of smell and taste of 559 people aged 65 to 99.
Impaired senses
They found 57% had either one sense, and in some cases both, impaired. Thirty-three percent had a good sense of smell but had lost a high degree of their sense of taste, 21% had moderate smell and taste impairment, and 3% had a strongly impaired sense of smell.
Impaired taste or smell can cause a decline in appetite and meal enjoyment. This can lead to malnutrition, and the researchers said there is a need to develop food that fits the sensory capacities of the elderly.
Useful knowledge
Sulmont-Rossé said: “This knowledge can be used by both the food industry and operators of homes for the aged. By concentrating on developing foods with pleasing texture and appearance, it should be possible for even those people with impaired sensory abilities to enjoy healthy meals.”
