Older adults who eat mushrooms more than twice a week can halve their risk of losing memory as well as language and attention skills, a key factor for the development of Alzheimer’s disease, finds a new study.

The study, led by a team from the National University of Singapore, found that even one small portion — three quarters of a cup — of mushrooms a week may still be beneficial to reduce the chances of mild cognitive impairment.

It also improved their cognitive tests and led to faster processing speed.

“This association is surprising and encouraging. It seems that a commonly available single ingredient could have a dramatic effect on cognitive decline,” said lead author Lei Feng, Assistant Professor at the varsity.

Chef Eduardo Garcia, founder of Maximo Bistrot and former migrant worker in the US, cuts mushrooms at his restaurant in Mexico City, July 13, 2017.

The reason could be a specific compound found in almost all varieties of mushrooms called ergothioneine (ET).

“ET is a unique antioxidant and anti-inflammatory which humans are unable to synthesise on their own. But it can be obtained from dietary sources, one of the main ones being mushrooms,” added Irwin Cheah, researcher from the varsity.

For the study, published in the Journal of Alzheimer’s Disease, the team collected data from more than 600 men and women aged above 60.

Anger is more harmful than sadness for older adults and may lead to health complications — potentially increased inflammation which is associated with chronic illnesses like heart disease, arthritis and cancer, say researchers.

The study, published in the journal Psychology and Aging, shows that anger can lead to the development of chronic illnesses whereas sadness did not.

“Sadness may help older seniors adjust to challenges such as age-related physical and cognitive declines because it can help them disengage from goals that are no longer attainable”, said study lead author Meaghan A Barlow from the Concordia University in the US.

For the study, the researchers analysed data from 226 older adults ages 59 to 93 from Montreal, Canada and grouped participants as being in early old age (59 to 79 years old) or advanced old age (80 years or older).

During the study, participants completed questionnaires about how angry or sad they felt.

The researchers suggest that education and therapy might help older adults reduce anger by regulating their emotions.

The research examined whether anger and sadness contributed to inflammation, an immune response by the body to perceived threats, such as infection or tissue damage.

“We found that experiencing anger daily was related to higher levels of inflammation and chronic illness for people aged 80 or above, but not for younger seniors,” added study co-author Carsten Wrosch.

“Younger seniors may be able to use that anger as fuel to overcome life’s challenges and emerging age-related losses and that can keep them healthier”, Barlow added.

The researchers suggest that education and therapy might help older adults reduce anger by regulating their emotions or by offering better coping strategies to manage the inevitable changes that accompany ageing. (IANS)
