The effect of nutrition on older people's mental health.

In the context of a rapidly ageing population, with an increasing prevalence of mood disorders and a greater incidence of physical illness in older adults, it is imperative that their healthcare needs are effectively addressed. Nutritional vulnerability increases in later life for various reasons, related to the physiological impact of ageing as well as social and economic challenges. Specific nutrients and overall diet quality may impact on mood. Depression and anxiety in turn impact on interest in and ability to eat and may further distort intake and exacerbate symptoms. Whether working with older adults living at home or in the care setting, nurses need to be aware of and able to identify, refer and support those who need help. This article aims to raise awareness and provides some practical guidance for nurses working with older adults experiencing mood disorders.
