A recent study has found that consuming berries, walnuts and grape juice can help to reduce brain aging, reducing the decline in cognitive function that often happens during the ageing process.

Including these foods in your diet is therefore of benefit for the aging population who is having difficulty with memory and recall, or for those with a family history of Alzheimer’s disease.
