Food odor thresholds in relation to age, nutritional, and health status

Odor perception plays an important role in nutrition. In the present study, the effect of aging and health status on detection of food odors is shown and interrelations with nutritional status are explored. We have tested 26 healthy young (20-25 yrs) and 23 elderly (61-74 yrs) subjects who were scre...

Description
Summary:	Odor perception plays an important role in nutrition. In the present study, the effect of aging and health status on detection of food odors is shown and interrelations with nutritional status are explored. We have tested 26 healthy young (20-25 yrs) and 23 elderly (61-74 yrs) subjects who were screened according to the SENIEUR protocol. Anthropometric measures and blood samples provided 20 parameters of nutritional status. A validated measurement procedure under forced choice conditions was used to quantify the detection thresholds of two food odors of which one had a trigeminal effect and the other mainly had an olfactory effect. There is a significant declining sensitivity for both odors. Our observations indicate that a relation between nutrition and odor perception in the elderly population exists. Whether olfactory deficits cause or are caused by increased nutritional risk deserves further study.
