     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.
