Mushrooms halve the risk of cognitive decline
Eating mushrooms on a regular basis got even more important. 600 Chinese senior citizens were observed by researchers for six years. In the end, the result was clear: senior citizens should eat mushrooms regularly.
600 Chinese senior citizens. 6 years. 300 gram per week.
A Chinese study which lasted for 6 years now came to an end. Researchers observed 600 Chinese senior citizens from Singapore and found out, that eating 300 gram of mushrooms per week reduces the risk for mild cognitive impairment (MCI) by 50%, that is what the Dutch magazine “Voedingsgeneeskunde” reported.
MCI is described as a “slight but noticeable and measurable decline in cognitive abilities, including memory and thinking skills”, indicated by the Alzheimer’s Association. Someone with MCI has an increased risk of developing Alzheimer’s or another dementia.
With an average portion of 150 gram, twice per week, the chances of MCI can be reduced. Also a smaller portion of mushrooms weekly may still be beneficial to reduce chances of MCI.
Not just the white button mushroom was tested. Also five other sorts like the golden, oyster and shiitake mushroom were tested. Also canned and dried sorts mushrooms. As a result, the researchers are interested in a compound called ergothioneine. This is a unique antioxidant and anti-inflammatory. Humans cannot produce it on their own. Mushrooms are one of the main sources.
Comparing participants with MCI with healthy individuals of the same age, the researchers of the National University of Singapore found out, that the plasma levels of ergothioneine in participants with MCI were much lower. As a result, the research led to the idea that increasing ergothioneine consumption by eating mushrooms might possibly promote cognitive health.
