You should cook most mushrooms before eating. Cooking makes their nutrients accessible and their tissues easy to digest. Further, some varieties of mushrooms may be toxic when consumed raw. This being said, a few mushroom species are PERFECTLY FINE to consume raw in small quantities.
The Raw Mushroom Controversy
Raw mushrooms are a common topic of debate amongst mushroom enthusiasts. Some say to avoid them at all costs, while others swear they’re perfectly fine to consume. The truth is, this isn’t a straightforward answer. It depends.
Mushrooms are diverse, just like the many plants we consume. Asking if you can eat mushrooms raw is like asking if you can eat vegetables raw. Carrots are perfectly fine but potatoes aren’t. Eggplants on the other hand are mildly toxic when consumed raw.
Unlike vegetables, only a VERY FEW varieties of mushrooms are ok to consume raw.
Why you should avoid Raw Mushrooms in your Diet
Most mushrooms cannot be properly digested when eaten raw. This is because their cell walls consist of a tough compound called chitin. Chiten is the same tough material that makes up the exoskeleton of insects. Cooking your mushrooms breaks down the chitin, making the mushrooms digestible. Without cooking, the nutritional and medicinal components attributed to mushrooms remain inaccessible. Further, certain varieties of mushrooms require cooking to remove toxic compounds.
