Can you still eat Jerusalem artichoke raw after it has sprouted?

Jerusalem artichoke, commonly known as sunchoke, can generally still be eaten raw if it has sprouted but not spoiled. However, if the tuber has sprouted and also shows signs of spoilage, it is usually not safe to consume. Detailed analysis is as follows:

Sunchoke contains protein, fat, carbohydrates, fiber, and minerals, and offers benefits such as regulating gastrointestinal function and assisting in lowering blood lipids and blood glucose levels. If the tuber has sprouted but not spoiled, it is generally still safe to eat raw, although the texture and taste may deteriorate. Before consuming sprouted sunchokes, it is recommended to remove the sprouts and surrounding areas to minimize unpleasant flavors, and thoroughly wash them with clean water.

If the sunchoke has sprouted and was improperly stored, leading to extensive bacterial or mold growth and visible spoilage—such as mold, softening, rotting, or foul odors—it should not be consumed. Eating spoiled sunchokes may increase gastrointestinal burden and cause discomfort such as bloating and abdominal pain.

In summary, sprouted sunchokes are generally safe to eat raw as long as there are no signs of spoilage. However, proper precautions should be taken, including removing the sprouts and adjacent tissue, thorough washing, and checking for any signs of deterioration. Additionally, individuals allergic to sunchokes should avoid consuming them.
