The six types of mushrooms studied: golden, oyster, shitake, white button, dried, and canned, share the ingredient known as ergothioneine
, an antioxidant, anti-inflammatory ingredient that could help slow cognitive decline.
"We're very interested in a compound called ergothioneine
(ET)," said Irwin Cheah, senior research fellow at the NUS Department of Biochemistry.
The reason could be a specific compound found in almost all varieties of mushrooms called ergothioneine
Announcing the findings on Tuesday (March 12), Dr Irwin Cheah, a senior research fellow at NUS' Department of Biochemistry, said this could be because mushrooms contain high levels of a compound known as ergothioneine
Indeed, the researchers noted substantial increases in certain antioxidants, including ergothioneine
and carnosine.In an earlier study, the same team of researchers showed that, as we age, the number of metabolites decline.
Selenoneine has a strong antioxidant potential in the redox cycle due to its unique structure of Se atom in the imidazole ring (similar structure to ergothioneine
represses inflammation and dysfunction in human endothelial cellsexposed to oxidized low-density lipoprotein.
Then, no direct correlation was found among these three parameters (Table 5) indicating that the antiradical capacity might be influence by other chemical classes in mushrooms such as phytosterols (ergosterol), glycosides, polysaccharides, ergothioneine
, carotenoids, ascorbic acid, other vitamins, and minerals.
At least Newsweek included a "may." But it also implied that ergothioneine
and glutathione, the "anti-aging" antioxidants in mushrooms, could do more than prevent wrinkles.
Researchers found that mushrooms are rich in the antioxidants ergothioneine
Its true that mushrooms contain many antioxidants, including glutathione and ergothioneine
. That seems to be where these claims start.
