The flowers are also yellow, but they are much smaller than the sunflower. The shoots die off in autumn every year.

Importance to health
The Jerusalem artichoke is also known among connoisseurs as the potato for diabetics, because the starch-like inulin is well tolerated by diabetics. Vegetables are also often eaten instead of potatoes on a diet because they are very low in calories.
It is very easy to explain why this is so: Our digestive system lacks enzymes that can break down inulin. So it cannot be converted into energy. And for this very reason, it cannot drive blood sugar up. Instead, the inulin enters the small intestine as indigestible fiber. When hydrated, the inulin swells and has a fast filling effect. Thanks to this property, Jerusalem artichoke is used in homeopathy for the production of weight-reducing agents. Inulin has a prebiotic effect in the large intestine, as it serves as a food source for the bifidobacteria.
This strain of bacteria is extremely important for human health as it combats harmful germs. Pathogens like yeast have no chance of multiplying. The prebiotic effect of inulin ensures a healthy intestinal flora, which is the prerequisite for a functioning immune system. But if you have never eaten Jerusalem artichoke, you should proceed slowly and increase the daily amount step by step. Because inulin can cause severe gas if the digestive system has not yet got used to the new carbohydrate.

The tubers lose their freshness during transport, so they should be processed as quickly as possible. However, if they need to be stored in the refrigerator for a few more days, it is best to put them in the vegetable drawer unwashed. This way, they can be kept for about a week. And once they are peeled, they turn brownish after a few minutes. As with the processing of apples, a few drops of lemon juice can also be used here.
When growing in your own garden, the tuber is only harvested shortly before preparation. The Jerusalem artichoke can also be stored in the freezer for a year. However, it must be blanched in salted boiling water before freezing. Brief blanching is also the best way to peel the gnarled tubers. Then it is quenched with cold water and skinned. However, if peeling is too annoying for you, you can also eat the tuber unpeeled.
Preparation tips
There are many ways to prepare Jerusalem artichoke. The vegetables taste good both raw and steamed, baked or deep-fried. If you like the tuber fresh and crisp, it is best to eat it raw in a salad.

The nutty taste is best preserved with gentle cooking or steaming. The sweet note, on the other hand, only comes into its own after frying or pureeing. Like potatoes, the Jerusalem artichoke can be served as hash browns or puree with meat and fish. Fried Jerusalem artichoke chips are not only delicious, but are also much healthier and contain far fewer calories than potato chips.
