These delicious fungi have been used for more than 6,000 years in traditional Chinese medicine, in which they’re believed to enhance longevity. They can be eaten fresh but when dried, their flavour and nutritional profile intensify. They contain high amounts of essential minerals and vitamins, and may protect against inflammation associated with cancer, although studies are incomplete. Many dried supplements have not been tested for effectiveness.

NUTRITIONAL BENEFITS

FOOD FOR THOUGHT

Shiitake mushrooms lend themselves to small-scale farming, right down to the level of individual households. All that’s needed is the mushroom culture and a natural or artificial log or sawdust box. The largest industrial growers are Japan and China, but some U.S. farmers have signed on. Shiitake are a highly sustainable food, and easy to add to your diet.
