Dietary variety and its effect on food intake of elderly adults.

Background Older people frequently have poor food intake. This
present study investigated the effect of dietary variety on food intake
in younger and older people. Methods Eighteen young adults (mean age =
26 years) and 18 older adults (mean age = 70 years) consumed four
consecutive courses of sandwiches on two occasions. In the plain
treatment, each course of sandwiches was of the same type, while in the
variety treatment four courses, each of a different type of sandwich,
were served. Each time the participants were presented with a serving of
sandwiches and asked to eat as much as they liked. Results In the plain
condition, the older adult group consumed more than their young
counterparts. This situation was reversed for the variety condition when
the young group ate more than the older adults. Interestingly, the older
adult group ate more when a variety of sandwiches was presented. This
may be contrary to what is predicted by the sensory-specific satiety
model of eating behaviour. Conclusions This study suggests that
presenting the older people with a varied meal may be a valid strategy
to improve food intake in this group.
