Question: In adults with moderate to severe cognitive impairment how effective is the use of crockery in primary colours in improving food and fluid intake? Which colours have been found to be most effective?

Answer:

No definite clinical implications can be made from the available evidence. The authors of one observational study suggested that clinicians and caregivers should consider implementing high contrast red or blue tableware to increase food and liquid intake in patients with Alzheimer's disease.  Although the results of this study were promising, the small numbers of participants, and the short duration of the study, suggests that more research in this area may be needed to confirm these results.
