The Jerusalem artichoke is a native of North America, growing wild along the eastern seaboard from Georgia to Nova Scotia. It can be produced throughout the United States, but the plant is better adapted to the northern two-thirds of the country.
The crisp, sweet tuber can be eaten raw and used like potatoes. Sunchokes also attract beneficial insects. Jerusalem artichoke tubers are high in potassium, iron, niacin, thiamine, copper, and phosphorus.
Jerusalem artichokes are very high in dietary fibers, including inulin, a fiber that is being studied for its potential to increase insulin sensitivity — an effect that might assist in the prevention of Type 2 diabetes.
The inulin has a positive effects on blood glucose attenuation, lipid homeostasis, mineral bioavailability and immunomodulation effects. Inulin and other polyfructosides are mainly used for the production of high-fructose syrups and artificial sweeteners in food industries.
