Which antioxidant found in mushrooms must humans obtain solely through diet?
Ergothioneine
Ergothioneine is highlighted as a very specific amino acid that the human body cannot synthesize internally, meaning its presence in the body is entirely dependent upon external dietary sources. Mushrooms are specifically recognized in this context as being the primary dietary source for this protective compound. Because it is so vital for defending cells and mitochondria against oxidative damage caused by free radicals, securing dietary intake of ergothioneine through regular mushroom consumption is essential for mitigating long-term risks associated with aging and chronic disease development. The text also notes that the concentration of this compound can vary, with species like oyster and shiitake often containing higher amounts.
