Mushrooms are full of antioxidants that may have antiaging potential

Mushrooms may contain unusually high amounts of two antioxidants that some scientists suggest could help fight aging and bolster health, according to a team of Penn State researchers. In a study, researchers found that mushrooms have high amounts of the ergothioneine and glutathione, both important antioxidants, said Robert Beelman, professor emeritus of food science and director of the Penn State Center for Plant and Mushroom Products for Health. He added that the researchers also found that the amounts the two compounds varied greatly between mushroom species.

[...] According to the researchers, who report their findings in a recent issue of Food Chemistry, the amounts of ergothioneine and glutathione in mushrooms vary by species with the porcini species, a wild variety, containing the highest amount of the two compounds among the 13 species tested. "We found that the porcini has the highest, by far, of any we tested," said Beelman. "This species is really popular in Italy where searching for it has become a national pastime."

[...] Cooking mushrooms does not seem to significantly affect the compounds, Beelman said. "Ergothioneine are very heat stable," said Beelman. Beelman said that future research may look at any role that ergothioneine and glutathione have in decreasing the likelihood of neurodegenerative diseases, such as Parkinson's disease and Alzheimer's disease.

    Wikipedia [wikipedia.org]:

    Beers vary in their nutritional content.[175] Brewer's yeast is known to be a rich source of nutrients; therefore, as expected, beer can contain significant amounts of nutrients, including magnesium, selenium, potassium, phosphorus, biotin, chromium and B vitamins. Beer is sometimes referred to as "liquid bread".

    No wonder beer has been used as a currency, and was the staple beverage for much of Europe for quite some time.

    Depends on whether your beer is filtered. But if you go back centuries or to ancient times this should have been no problem:

    https://en.wikipedia.org/wiki/Kombucha [wikipedia.org]
    https://en.wikipedia.org/wiki/Kvass [wikipedia.org]

    As its primary ingredient is rye, kvass is a good source of vitamin B-1 and B-6, magnesium, phosphorus, amino acids, and pantothenate. It is also rich in lactic acid and simple sugars, which contributes to its pleasant, thirst-quenching taste, provides ample calories to fuel physical activity, and may improve digestion, as with other lacto-fermented foods such as yogurt and sauerkraut.

    Do any of these fermented beverages contain vitamin B12?

    Some nutritional yeast products also contain vitamin B12.

    Reminder to try to make this:

      B12 is soluble in water. Filtering won't remove it.

      Some nutritional yeast products also contain vitamin B12.

      Only because they've been fortified. Yeast, like other fungi, can't synthesize B12. It's only made by bacteria, or archaea.

    https://en.wikipedia.org/wiki/B_vitamins [wikipedia.org]

    Although the yeast used to make beer results in beers being a source of B vitamins,[19] their bioavailability ranges from poor to negative as drinking ethanol inhibits absorption of thiamine (B1),[20][21] riboflavin (B2),[22] niacin (B3),[23] biotin (B7),[24] and folic acid (B9).[25][26] In addition, each of the preceding studies further emphasizes that elevated consumption of beer and other alcoholic beverages results in a net deficit of those B vitamins and the health risks associated with such deficiencies.

    Then what provides vitamin B12 from birth to age 21, when consuming beer becomes legal in SN's home country?
