Whether you love mushrooms are not, here’s a great reason to eat them: They counter the effects of aging.

Researchers at Penn State University found that mushrooms were rich in two very powerful antioxidants which can reduce oxidative stress in the body. Some mushrooms, like porcini, were found to have higher levels of these antioxidants than others.

Professor Robert Beelman of Penn State explained, “What we found is that, without a doubt, mushrooms are the highest dietary source of these two antioxidants taken together, and that some types are really packed with both of them. We found that the porcini has the highest, by far, of any we tested. This species is really popular in Italy where searching for it has become a national pastime.”

The researchers also noted that cooking the mushrooms did not significantly alter the antioxidant levels. The researchers suggested consuming more mushrooms on a regular basis in order to obtain the antioxidant benefits which they provide.
