Eating fresh fruit and oily fish could stave off dementia, the Alzheimer's Society has said.
Dr Susanne Sorensen, head of research at the charity, said that fresh fruit and vegetables contain lots of vitamins and antioxidants, which are known to help protect the brain.
Furthermore, the fatty acids found specifically in oily fish have been seen to help protect the heart, blood vessels and decrease the risk of dementia, pointed out the expert.
"Some research has suggested that caffeine, and various spices and herbs including curcumin, sage and lemon balm, might have a protective effect on the brain. However, research is continuing and there is no conclusive evidence as yet," she continued.
This follows research conducted at the Karolinska Institutet in Sweden, which revealed that being overweight or obese in middle age could result in a higher risk of developing dementia in later life.
