What Is Jerusalem Artichoke?
Jerusalem artichoke (Helianthus tuberosus) is the underground tuber of a sunflower relative in the daisy family. It has a rough skin that resembles ginger and a mildly sweet, nutty flavor.
Despite the word “apple” in its Turkish name, yer elması, it is not a fruit; it belongs to the root vegetable group. It is harvested in fall and winter. Because its skin is thin, it is often eaten unpeeled after being scrubbed thoroughly.
Nutritional Values of Jerusalem Artichoke
Jerusalem artichoke provides 73 kcal per 100 grams, making it moderate in calories compared with other root vegetables. Its most notable component is inulin, a type of prebiotic fiber; it is also rich in potassium and iron.
What Are the Benefits of Jerusalem Artichoke?
The inulin in Jerusalem artichoke has been studied as a prebiotic fiber that may support gut flora. Its potassium and iron content also contribute to a balanced diet.
This is general information; Jerusalem artichoke is a food, not a substitute for medical treatment. Since inulin may cause gas and bloating in people with sensitive bowels, starting with a small amount the first time you try it is recommended.
How to Choose Jerusalem Artichoke
Fresh Jerusalem artichokes are firm, unwrinkled, and smooth.

- The skin should look unwrinkled and moist.
- Small, smooth tubers may be easier to peel and can be preferred.
