It's that time of year again. We've overindulged and now feel slightly guilty about it. Well I do anyway. So our thoughts turn to healthy eating - something we're constantly told is good for us and can help lower our risk of a whole range of diseases. Is it true? Can what we eat affect our chances of developing dementia?
I have always been an avid follower of Louis Theroux's documentaries. Not only because I love the man but because they have always been an interesting and engaging watch. His most recent work aired last week on the BBC 'Extreme love - Dementia' and it proved to be his most emotionally rewarding documentary so far.
