Newsweek reports that researchers from Pennsylvania State university fond that mushrooms are "without a doubt" the single biggest source of two antioxidants found to have anti-aging properties. The compounds, ergothioneine, and glutathione are found in a number of mushrooms, but some species have more than others.

The front-runner was the wild porcini mushroom, which had more the antioxidants "by far" than other species tested. However, common white button mushrooms also had some positive effects.
