Recently I've been building a wiki on neighbourhood support for older people, to try and focus information and understanding on this crassly-overlooked issue. I'll open it soon, but meanwhile if you're interested in contributing please get in touch.
Here's the sort of thing that goes into the pot, so to speak: ILC-UK have published a paper by Lisa Wilson on Personalisation, nutrition and the role of community meals. It notes that there is a strong underlying economic argument for supporting older people to remain independent and in their own homes, and for ensuring good nutritional status. It begins with a striking statistic:
'There are currently more people in the UK receiving meals in their own home than there are older people in care homes.'
Hence one of the main arguments:
'Meal provision and access to food must be considered a core part of social care packages and meals must be provided to at risk groups, not just to those who have reached the point of being unable to manage themselves.'
