Alzheimer’s Disease

Affecting almost half a million people in the UK, Alzheimer’s disease is the most common type of dementia. The exact cause of the disease isn’t known but studies suggest that eating a healthy diet that follows the balance of foods outlined in the Eatwell Guide may help to reduce the risk or delay the onset of the condition. In particular, there seems to be a link between cardiovascular disease and an increased risk of Alzheimer’s disease, so eating a diet that’s good for a healthy heart makes sense. Some studies show that higher intakes of fish and an omega-3 fat called DHA may be linked to a lower risk of Alzheimer’s disease, although there’s not enough evidence to support the use of omega-3 supplements to prevent cognitive decline. Oily fish are particularly rich in omega-3 (although white fish and shellfish still contain some) – experts recommend we eat two portions of fish each week, one of which should be oily.
