According to a Singapore study, eating more mushrooms can ” reduce the risk of brain degeneration.”
But how to eat mushrooms is to eat more? About twice a week or more can prevent memory and language problems after the age of 60.
Studies have found that mushrooms have a unique antioxidant that can protect the brain.
According to research, the more mushrooms people eat, the better they perform in thinking tests.
However, researchers said it is currently unlikely to prove a direct link between fungi and brain function.
The findings of the National University of Singapore are based on a survey of 663 adults over the age of 60 on their eating and living habits. Researchers followed them for 6 years (2011-2017).
Researchers found that eating mushrooms reduced the risk of mild cognitive impairment. Of those who ate mushrooms more than twice a week, about 9% had cognitive impairment, while the proportion of those who ate mushrooms less than once a week was 19%.
The results of the study are published in the Journal of Alzheimer’s Disease.
Experiments on Mushrooms and Cognition
Mild cognitive impairment (MCI) can make people forgetful, affect people’s memory, and may cause problems such as language and attention. For example, they may not be able to find where to put things. These changes are subtle.
These symptoms are common to the elderly, but they are not so serious as to cause dementia.
Participants need to answer whether they often eat these 6 kinds of mushrooms: Pleurotus ostreatus, Lentinus edodes, white mushrooms, dried mushrooms, golden mushrooms and canned mushrooms.
People who eat mushrooms frequently perform better in some intelligence tests. At the same time, they are processing faster. This is especially obvious for those who eat more than two or more than 300 grams of mushrooms per week.
Researchers said the link was both surprising and encouraging.
Feng Lei, associate professor of psychology at the National University of Singapore, said that this may be related to a common ingredient in mushrooms, which may have a significant impact on cognitive decline.
But Feng Lei said that what he was talking about here was a combination of many factors, such as tea, green leafy vegetables, nuts and fish, which are all good for the body.
Researchers pointed out that mushroom is one of the foods rich in ergothioneine, which is an antioxidant and anti-inflammatory agent that human beings cannot make on their own.
Mushrooms also contain other important nutrients and minerals, such as vitamin D, selenium and spermidine, which can protect neurons from damage.
Of course, there is still a long way to go in order to prove the direct connection among them.
Diet and lifestyle
However, researchers admit that the data relied on in this experiment are information reported by volunteers themselves and may not be accurate.
Dr. Picot, head of the British Alzheimer’s Association, said, ” There are many factors contributing to dementia. If you change your lifestyle and diet, it is estimated that one-third of the cases can be prevented. “
Dr. Picot also said that dementia was one of the top 10 causes of death. But people can take actions to reduce their risks.
Therefore, it is important that we should give guidance and suggestions to people according to the consistent evidence of multiple studies, and not get carried away by any single research result.
Dr. Picot suggested that people should eat more foods rich in fruits and vegetables, including mushrooms.
At the same time, he said, ” our best advice is to eat less salt and sugar, exercise more, drink a little and don’t smoke.”
