A team from the Department of Psychological Medicine and the Department of Biochemistry at Yong Loo Lin School of Medicine National University of Singapore (NUS) has discovered it older people who use more than two standard servings of mushrooms, like mushrooms or mushrooms, every week can have one 50% reduced odds having mild cognitive impairment.
One portion was defined as three quarters of cup of cooked mushrooms with an average weight of about 150 grams. Two portions would correspond to approx. half of a plate. while The size of the portions serves as a guide, it was shown to itself a small portion a week can be beneficial to reduce the chances of deterioration.
"This connection is surprising and encouraging. A single commonly available ingredient could have a dramatic effect on cognitive decline", Assistant Professor Lei Feng, from the US Psychological Medicine, and lead author of this work.
Study that It has been done for six years, from 2011 to 2017, collected data on more than 600 Chinese elderly over 60 living in Singapore. The research was conducted with support from the Life Sciences Institute and Mind Science Center at NUS, as well as National Medical Research Council of the Ministry of Health in Singapore.
The results published in the Journal of Alzheimer's Disease show that they can also identify other dietary factors it could be associated with a healthy brain aging and a lower risk of conditions related to the age of the future.
Mild cognitive impairment is usually considered to be the stage between cognitive decline in normal aging and the more severe decrease in dementia. Affected seniors often show some form of memory loss or forgetfulness and they can also show deficits in other cognitive functions such as language, attention and visuospatial abilities. However, the changes can be subtleThen not they experience deactivating cognitive deficits that affect daily life activitieswhich are characteristics of Alzheimer's and other forms of dementia.
"People with mild cognitive impairment can still perform their normal daily activities. what we had to decide in this study is if these seniors had one worse performance in standard neuropsychological tests than other people of the same age and level of education, "Feng explained.
The researchers conducted interviews and extensive tests with the elderly to determine an accurate diagnosis. "The interview takes into account demographic information, medical history, psychological factors and eating habits. A nurse has measured blood pressure, weight, height, grip and walking speed. He also performs a simple screen test on cognition, depression and anxiety, "they explained.
Then a standard two-hour neuropsychological evaluationtogether with a dementia rating. The overall results of these tests were analyzed in depth with expert psychiatrists involved in the study to obtain a diagnostic consensus.
Mushrooms and cognitive impairment
Six mushrooms consumed in Singapore were mentioned in the study. They were golden mushrooms, oyster mushrooms, shiitake and white button and dried and canned mushrooms. Researchers have also indicated that other unfermented fungi are also likely to have beneficial effects.
The researchers believe it can because of a specific compound found in almost all varieties. "We are very interested in a connection called ergothionein (ET)," explained Irwin Cheah, lead researcher at the US Department of Biochemistry.
Ergothioneine is a unique antioxidant and anti-inflammatory that humans cannot synthesize alone. But you can get it from food sources, one of the most important being mushrooms.
