Mushrooms May Affect Cognitive Health

Mushrooms May Affect Cognitive Health

Love them or hate them, mushrooms are a wonderful addition to your diet. Recent research has shown that mushrooms may have even more health benefits than we previously realized!


Why are mushrooms good for you?


Many edible varieties of mushrooms are found in the vegetable section of your local grocery store. However, mushrooms are not vegetables. Mushrooms are actually fungi. Edible varieties contain a high amount of antioxidants, protein, dietary fiber, vitamins and also minerals.

According to recent research, eating mushrooms may also reduce the risk for mild cognitive impairment (MCI).


What is Mild Cognitive Impairment?


MCI is a type of memory impairment which is often a precursor of Alzheimer’s disease. It is the stage between the normal cognitive decline of aging and the more serious decline of dementia. MCI involves problems with language, thinking, memory and judgment that are beyond normal changes as a person ages.

Patients with mild cognitive impairment may be aware that their memory or mental functioning is “off”. Others may also notice a change. MCI is not severe enough to interfere with normal day-to-day functioning, however.

Mild cognitive impairment may increase someone’s risk of developing Alzheimer’s disease or other neurological conditions later in life.


What is the relationship between mushrooms and MCI?


Researchers in Singapore gathered data on 663 Chinese men and women. All of the participants in the study were over the age of 60. Researchers recorded diet information, including data about the participant’s mushroom consumption. The investigators focused on the consumption of some of the most common mushrooms that people in Singapore eat. These varieties include:


oyster mushrooms
golden mushrooms
shiitake mushrooms
dried mushrooms
canned button mushrooms
white button mushrooms


They also interviewed each participant and conducted various cognitive tests.

This controlled study accounted for various factors including socioeconomic factors, health and other behaviors. Researchers also considered each participant’s consumption of vegetables, meat, and green fruits and nuts. The participants who ate one to two 5- ounce portions had a 43 percent reduced risk for MCI in comparison to those who had one portion or less. Participants that consumed more than two portions, however, had a 52 percent reduced risk. 1


Why do mushrooms help ward off Alzheimer’s?


It is unclear why this relationship exists between mushrooms and a reduced risk of MCI. Mushrooms do contain various antioxidants that may inhibit the buildup in the brain of amyloid beta and tau. These are proteins that are present during Alzheimer’s disease.


What are the signs of Alzheimer’s?


Some of the top signs of Alzheimer’s include:

difficulty remembering what just happened
struggling to manage bills or finances
misplacing things
vision problems
inability to follow conversations
difficulty completing day-to-day tasks
losing track of dates and times
poor decision making
inability to plan or problem solve
withdrawing from work or social activities
getting easily lost in their normal environment
mood/ personality changes
uncommon feelings of depression, suspicion, anxiety or confusion
