Already a number of studies have shown that citrus fruits can help protect the brain from developing dementia or Alzheimer’s. Citric acid contains nobiletin. In animal tests that has been shown to delay or reverse damage to memory.
But now a new study is the first to research the effects citrus fruit might have on people most at risk. They found those people with a daily intake of citrus were 23 per cent less likely to develop dementia than those eating it less than twice a week.
