Eating mushrooms may cut your chances of dementia in half: Study

I'm making zero claims here: This caught my eye because I've lost several family members to dementia and wanted to put it up for discussion. I mean, this would be great news if true, and not woo.

The study being cited:
http://news.nus.edu.sg/research/mushrooms-reduce-cognitive-decline
A team from the Department of Psychological Medicine and Department of Biochemistry at the NUS Yong Loo Lin School of Medicine has found that seniors who consume more than two standard portions of mushrooms weekly may have 50 per cent reduced odds of having mild cognitive impairment (MCI).

A portion was defined as three quarters of a cup of cooked mushrooms with an average weight of around 150 grams. Two portions would be equivalent to approximately half a plate. While the portion sizes act as a guideline, it was shown that even one small portion of mushrooms a week may still be beneficial to reduce chances of MCI.

“This correlation is surprising and encouraging. It seems that a commonly available single ingredient could have a dramatic effect on cognitive decline,” said Assistant Professor Feng Lei, who is from NUS Psychological Medicine, and the lead author of this work.

The six-year study, which was conducted from 2011 to 2017, collected data from more than 600 Chinese seniors over the age of 60 living in Singapore. The study was carried out with support from the Life Sciences Institute and the Mind Science Centre at NUS, as well as the Singapore Ministry of Health’s National Medical Research Council. The results were published online in the Journal of Alzheimer’s Disease on 12 March 2019.

    I've read other things about how good mushrooms are for you and I always have good intentions to eat them, (I buy 1-2 packages every time I get groceries), but I forget about them more times than I remember them for some reason? It's like they become invisible once they enter my home :p

    Interesting! I see that they want to do a randomized trial next where they will be giving the pure compound they think is responsible.

    From a nutrition nerd perspective this is interesting and definitely not woo, but studies like this can lead to "superfood" status, and that's where the woo often creeps in.

    You take a healthful food like mushrooms (blueberries, beets, kale etc.), compare people who eat it to people who don't, and study a resulting health benefit.

    The nutrient in question here, ergothioneine, is highest in some varieties of mushroom, however black beans and oat bran are also good sources. A person with a healthful, varied diet could conceivably reap the same benefit without eating a single mushroom. That's good news for people who don't like mushrooms (or blueberries, beets, kale etc.).

    It's wonderful that we're learning more about the benefits of different nutrients found in healthful foods and why they're so good for us, but we shouldn't lose sight of the fact that our diet as a whole matters a whole lot more than whether or not we consume the superfood of the moment.

    Not woo is good to hear, and that's an excellent point regarding the superfood status. Thank you 🙂

    ditto. Mine are gone quick though. I love, love, love mushrooms. And I majorly stock up on the canned Roland straw mushrooms whenever I go to Pricerite - I'm really fond of those.

    i don't do mushrooms. i want to. but i just not a fan of taste and/or texture
    but i like cooking and so many wonderful dishes include mushrooms

    one more reason for me to try to acclimate my tastebuds if this study and studies like it continue to support the idea

    Depending on the specifics of the study, might just be correlation. Those consuming a lot of mushrooms are probably eating a high-vegetable, varied diet. Mushrooms are often in things like stir fry and soup where lots of healthy, nutritious ingredients tend to be agglomerated together. Higher mushroom consumption might just tend to correlate to a healthier, varied, more nutritious diet in general.

    Quite possible. If that's the case I need to up my veggie intake, not to mention there is never a bad reason to have more mushrooms :)

    I'll be following this with interest. I love mushrooms and I'm old, so... ;)

    Mushrooms have a taste?

    slimy and weird

    I generally put slimy into the texture category, and I don't know what weird is as a taste besides times I've licked myself.
    Might be the preparation of the mushrooms. I could see canned as being slimy, but fresh, I think of them as being more rubbery and dry in texture.
    I seriously just don't notice any real flavor to them, just the texture aspect.

    Ate a lot of mushrooms back in the 70's. Gave me temporary dementia.

    Life changing stuff.

    @AnnPT77 the renaissance fair by us has portabella burgers and butter and garlic button mushrooms and they all smell wonderful but nope. they go in my mouth and then come right back out. can't even force a swallow :disappointed:

    but that's an interesting idea about ground mushroom

    I love mushrooms and have them a few times a week so hopefully there is some truth in it :smiley:

    To me, they taste kind of earthy, savory, and rich. I'm a fan of the taste, but I can see how people could dislike it.

    I read that article the other day and was intrigued as well (being old and all :) ) Ignoring the "Eat mushrooms to reduce your chance of dementia!" hype I thought it was an encouraging exploratory study and am delighted that they are following up with other studies to narrow down the source of the apparent benefit. I think they'd be able to start human trial fairly soon (probobly as soon as funding is available) since it just involves food (or derivitives) that we already know is safe and doesn't supplant any regular treatment patients would be receiving.

    I use them in my mock liver every week. 340 grams mushrooms, 227 grams green beans, and an onion sauted on medium-high heat for 10 minutes in a teaspoon of oil. Into the food processor with 1/4 cup walnut pieces and 1/4 cup water plus salt and pepper to taste. Process to desired consistency.

    I'll also throw them into stir-fries and there's the end of a package sitting in my slow-cooker stew right now.

    Yes please. Sauteed in olive oil, butter and garlic....I want some now.

    eating some right now. Sauteed with butter-flavored oil spray, some sesame oil, garlic, onion, zucchini, collard greens, canned chicken, black olives, and water chestnuts.

    Do you have actual gagging / retching reactions to them? I had issues like as a child towards most vegetables, even something I'd call similarly low in flavor like lettuce. Overtime I just powered through it so that it took more to elicit a reaction until at this point in my life I usually have 4 to 5 servings of vegetables as part of lunch.

    depends on the day. somedays brain won't swallow. other days, the brains says the whole stomach is infected with mushrooms and a system flush is needed

    i want to like mushrooms :disappointed:

    It's almost morel season here.

    I rarely get some, but possibly the best food on earth, in my world. Yes to "earthy, savory and rich", and then some. Plus, if you're not careful, you have an opportunity to eat your RDA of tiny ants. ;) (As a veggie, I avoid this.)

    (NB the commercial morels are OK, the usually-fresher wild ones much better, richer. Maybe the commercial ones would be as good if I could ever find properly fresh ones: The ones sold as "fresh" are kind of dried-out, because that happens fairly fast. I've only had home-dried wild ones once that I can recall, and remember them as richer than dried ones that are commercially available.)

    I completely can't relate to thinking mushrooms don't have much flavor, in general. They're a classic umami flavor. Some are more flavorful than others, usually the darker ones richer; the flavor comes out better cooked, in most, IMO. But most of them, full of delicious flavor. (The canned ones don't have much, and that not very good IMO.)

    I don't think of the texture as slimy, but I can kind of see how someone could.
