EAT MORE MUSHROOMS: ITALIAN MUSHROOM SALAD

April 12, 2019 6 Comments

A study in last month’s Journal of Alzheimer’s Disease had me googling frenziedly for several hours. Could I really reduce my chances of mild cognitive impairment (MCI) by 50% merely from eating a few more mushrooms?

There are moments when I’m quite sure I already have mild cognitive impairment (MCI, defined as the stage between the usual cognitive decline of ageing and the beginnings of dementia: typically characterised by memory loss, forgetfulness, inability to focus. Sound familiar?)

So the prospect of munching on a few mushrooms to sustain my brain was enticing. But is the science robust and is the data reliable?

This particular study involved 600 people, over the age of 60, who were monitored for six years, in Singapore. You can read the details here, but the main finding was that those who ate more than 300g of mushrooms a week (effectively two portions) appeared to reduce their odds of MCI by 50%. Even a single small portion of mushrooms (per week) seemed to reduce the chances of MCI.

IT’S ALL ABOUT THE ERGO…

The Professor who led the study singled out a compound called ergothioneine: ‘a unique antioxidant and anti-inflammatory which humans are unable to synthesise on their own.’ And which is found in all types of mushroom. Even the ubiquitous and pallid button mushroom.

A 2016 study had already found that elderly people with MCI had much lower levels of ergo than those with no signs of MCI, prompting its authors to suggest that an ergo deficiency may be a risk factor for brain degeneration. And, conversely, that a diet rich in ergo might prevent the brain sliding into decline.

Another study – of 13,000 elderly Japanese – showed that those who ate more mushrooms had less incidence of dementia.

Meanwhile, over in the United States, Professor Robert Beelman studies the extraordinary properties of mushrooms and fungi from his dedicated laboratory at Pennsylvania State University. He points out that mushrooms are ‘good sources of protein, B-vitamins, fibre, immune-enhancing sugars… called beta-glucans… selenium, Vitamin D, glutathione and ergothioneine.’

The last four on that ingredient list, he says, ‘are known to function as antioxidants that can mitigate oxidative stress and all are known to decline during aging.’

In 2006 Prof Beelman and a student, Joy Dubost, discovered that mushrooms contained 10 times more ergo than any other food source.

LET’S NOT FORGET THE GLUTATHIONE…

They also found that mushrooms contained the ‘master antioxidant in all living organisms’, glutathione. According to the Prof, ‘no other food even comes close to mushrooms as a source of both these anti-oxidants.’

The Prof and his team are currently examining the potential of ergo (sourced from mushrooms) to treat neurodegenerative ageing diseases like Parkinson’s, dementia and Alzheimer’s, and multiple sclerosis.

The only other way to obtain ergo is by eating foods that have grown in fungi-rich soils (or from animals that have eaten grass from fungi-rich soils). Early research into growing oats suggests that not tilling/ploughing the soil too ruthlessly can protect fungal populations in soils, leading to more ergo in crops.

You can read Prof Beelman in his own words here.

Knowing the potential ergo-power of mushrooms is the perfect excuse to eat more of them. I was served a version of this simple mushroom salad in a little café outside Florence last year, where I was researching my novel, Frieda. The mushrooms were wild and a glorious pale amber colour with flushed gills. I, however, use whatever I can find. Chestnut mushrooms taste more earthy and complex than button mushrooms, but Portobello work too. Slice them as thinly as you can.

ITALIAN MUSHROOM SALAD

  • 2-3 medium mushrooms per person, as fresh as possible, wiped clean
  • Olive oil (the best you can lay your hands on)
  • Parmesan
  • A few springs of parsley

Thinly slice the mushrooms. Drizzle with plenty of olive oil. Season, using lots of black pepper. Sprinkle on a thin layer of coarsely grated parmesan and top with a little chopped parsley.

We are so mushroom-obsessed, our book has an entire section on them. If you’re interested in knowing more, you can pre-order The Age-Well Project here.

    Do you get the same results from cooked mushrooms as from raw ones?

    Yay, I love mushrooms! It was also nice to note that the study involved 300 gm cooked mushrooms per week – I rarely eat fresh mushrooms.

Who should invest in a pair of walking (sometimes Who  should invest in a pair of walking (sometimes called trekking) poles?

Well, those of us  who enjoy hiking. Or those of us with lower back pain, obesity, Parkinson’s or general frailty.  Or those of us that want a more youthful gait. Or those of us that want to work all our muscles without going to a gym or messing around with weights. Or those of us that want our exertions to feel less … exerting! 

Sooooooo pretty much anyone who wants to age well! 

But which poles, and what do we do with them? It’s all on the blog - link in bio

RIP Kane Tanaka, the world’s oldest living perso RIP Kane Tanaka, the world’s oldest living person who died last week aged 119. She spent her last years playing the strategy board game, Othello, apparently. Asked for the happiest moment in her life, she replied ´Now’. She has been ‘replaced’ as the oldest person alive by a French nun who is currently 118 and survived catching Covid last year. Asked if Covid had frightened her, she replied ´no… because I wasn’t afraid to die.’ Draw your own conclusions (if you want to)!
