Does protein and energy supplementation benefit older people at risk of malnutrition?

Best practice recommendations:
Despite the weak quality of the majority of studies included in this review, as evaluated according to the criteria set for randomised controlled trials, the small increase in weight gain and the decrease in mortality - for undernurished groups only - provides justification for continuing the prescription of protein and energy supplements.
However, other interventions intended to improve nutritional status should be integrated. These could include providing targeted dietary advice and palatable, preferred and nutritious food, in addition to addressing non-dietary barriers such as depression and dental problems.
