The number of people with dementia is predicted to reach 81 million within 30 years from about 25 million today. But plenty of studies have suggested that what we eat may effect how we think.
Dr Jeroen Schmitt, head of cognitive sciences at the Nestle Research Center in Switzerland. explains why there is plenty of evidence to suggest that diet and the lifestyle can help ease the burden of dementia and Alzheimer's.
At the other end of the age-spectrum, optimal development of the brains of our children is also a target for many in nutrition circles.
Dr Schmitt also explains why the gut may open up novel and innovative ways of improving cognitive function. It all adds up to a new meaning to thinking about what you eat.
