Q. I've heard that mushrooms contain carcinogens. Is that true?
A. Some researchers have suggested that enzymes in the digestive system can convert agaritine, a natural substance found in several mushrooms of the Agaricus species (which includes the common “button” mushroom) into carcinogenic by-products or free radicals. However, there is no conclusive evidence showing a link. In fact, the reverse may be possible since mushrooms contain selenium, beta-glucans and other substances that may have anticarcinogenic properties. So dig in and enjoy, from portobellos to porcinis!
