Has anyone here done a deep dive into the area of mushrooms and nutritional benefits? Any thoughts on how strong this research is? Have you changed your eating habits at all based on the science? Are there any good human clinical studies you are aware of?
I’ve increased my use of shiitake mushrooms (easily available and reasonably priced at the local Costco) but beyond that I have not really dug into it.
Hericium erinaceus Improves Recognition Memory and Induces Hippocampal and Cerebellar Neurogenesis in Frail Mice during Aging
We developed an integrated frailty index based on both phenotypic and recognition memory performances. Hericium erinaceus (H. erinaceus ) is a medicinal mushroom that improves recognition memory in mice. By using HPLC-UV-ESI/MS analyses we obtained standardized amounts of erinacine A and hericenones C and D in H. erinaceus extracts, that were tested in our animal model of physiological aging. Two-month oral supplementation with H. erinaceus reversed the age-decline of recognition memory. Proliferating cell nuclear antigen (PCNA) and doublecortin (DCX) immunohistochemistry in the hippocampus and cerebellum in treated mice supported a positive effect of an H. erinaceus on neurogenesis in frail mice.
So it turns out the dried stuff in the pantry looks good re mushroom species. Wife said she bought at local Costco. Oyster and Porcini…I can tell from the smell. I put some to hydrate, need to decide how to use in a meal. The water turns a very dark brown, that cannot be thrown away, must be consumed…some of the many of the good nutrients may have absorbed in the water. Red wine reduction low heat? Classically I would infuse into a risotto, but I’m keto
I do the same for greens I cook/wilt…say spinach wilted, when I let drain, I save that water and drink it. Or if I boil rapini, I save the water and drink it.
I noticed Amazon carries a sku too, but when you look at the species, they are lesser quality.
I am a strong believer that mushrooms have a play in longevity. I try to make sure I get a fair few on my dinner plate. I also take L-Ergothioneine supplement 5mg everyday, made by Realmushrooms. Also Reishi mushroom supplement by the same manufacturer. Reishi has been studied a lot, and just like Astaxanthin all studies comes out positive, so basically you can’t refute the benefits. ITP should start mouse studies on longevity I think, that would be interesting.
Thank you for putting this ergothionine information together. We have been taking mushroom extract powders from Real Mushrooms for 2 years. This includes Lions Mane, Reishi, and Turkey Tail plus there ergothionine product. They don’t seem to have Shitake so we get that from Bulk Supplements.
Real Mushrooms has only fruiting bodies in their products.
So I sautéed the hydrated mushrooms (and liquid) with some spices, and rendered down to a thick sauce with a teaspoon of starch. Put some grass fed beef over top, drizzled some high oleocanthal EVOO. Side of whole head roasted cauliflower with yogurt, pistacchio, and goji berries. Plain wilted spinach not shown.
“Searching for a Longevity Food, We Bump into Hericium erinaceus Primordium Rich in Ergothioneine: The ‘Longevity Vitamin’ Improves Locomotor Performances during Aging”
Particularly, H. erinaceus primordium (He2) extract contains a high amount of Ergothioneine (ERGO), the longevity vitamin. Herein, we revealed the preventive effect of ERGO-rich He2 extract in a preclinical model, focusing on locomotor decline during ageing monitored through spontaneous behavioral test. This effect was accompanied by a significant decrease in some oxidative stress markers (NOS2, COX2) paralleled by an increase in P53, showed in cerebellar cortex cells and fibres by immunohistochemistry. In summary, we demonstrated the neuro-protective and preventive effects of He2 extract during aging, probably due to its peculiarly high ERGO content.
Another commonly used mushroom in East Asian countries is Hericium erinaceus. It is an edible mushroom with medicinal value, which is also known as Lion’s Mane Mushroom or Hou Tou Gu in Chinese or Yamabushitake in Japanese.
Polysaccharides extract of H.erinaceus has significant anticancer and immunomodulation activities. It enhanced T cells and macrophages secretion and enhanced the expression of cytokines
It has the ability to prevent the impairments of spatial short-term and visual recognition memory induced by β-amyloid peptide in animals . Daily oral administration of H. erinaceus could promote nerve regeneration after injury in rats
