"'Encouraging'

Mild cognitive impairment (MCI) can make people forgetful, affect their memory and cause problems with language, attention and locating objects in spaces - but the changes can be subtle.

It is not serious enough to be defined as dementia.

The participants in the study were asked how often they ate six different types of mushrooms: oyster, shiitake, white button, dried, golden and tinned.

Mushroom eaters performed better in brain tests and were found to have faster processing speed - and this was particularly noticeable in those who ate more than two portions a week, or more than 300g (10.5oz).

"This correlation is surprising and encouraging," said assistant professor Lei Feng, the lead study author, from the university's department of psychological medicine."

"the countries that have more ergothioneine in their diets, countries like France and Italy, also have lower incidences of neurodegenerative diseases, the average amount of the antioxidant seen in the diets in these countries is about 3 milligrams per day, or about five button mushrooms. While people in countries like the United States, which has low amounts of ergothioneine in the diet, have a higher probability of diseases like Parkinson's Disease and Alzheimer's."
