Quite possibly everything you ever wanted to know about …
Jerusalem artichoke is a root vegetable (a tuber), somewhat similar in
use to, and a possible substitute for, the potato.
- The Jerusalem artichoke plant (Helianthus tuberosus) is a species of sunflower (the decorative type that we usually call a sunflower is Helianthus annuus).
- Some other names for both plant and veggie are sunchoke, sunroot, earth apple, Canada potato, and topinambour.
- Chokes are a native of eastern North America, perennial, easy to grow, spreads easily, reaches 3′-12′ in height, and has yellow flowers
- Chokes are not related to the regular globe artichoke (which is a member of the thistle family).
- Origins of the name are not entirely clear. “Jerusalem” may come from a corruption of the Italian for sunflower, girasole, and “artichoke” from a similarity in taste.
- Chokes have around 70 calories per 100g, about the same as potatoes.
- Chokes are high in potassium, with significant iron and magnesium, and also contribute phosphorus, calcium, vitamin C and a bunch of B vitamins including thiamin.
- Chokes are high in the carbohydrate, inulin, a dietary fiber and prebiotic (fuels beneficial bacteria in the gut) that’s also big in garlic, onions, Echinacea, and bananas.
- Thanks to inulin, which the human digestive system does not convert into sugars, chokes score low on the glycemic index (GI), which means no blood sugar spikes.
- Chokes may cause gas, particularly when eaten in large quantity, for the first time, and by people with sensitivities.
