Description
Distribution of Artichoke Tubers doesn't start until Early April
Jerusalem artichokes are easy to cultivate, which tempts gardeners to simply leave them completely alone to grow. The quality of the edible tubers degrades, however, unless the plants are dug up and replanted in fertile soil. The plants grow tall foliage up to 3 meters high and produce large yellow flowers similar to the sunflower they are related to.
The artichoke contains about 2% protein, no oil, and a surprising lack of starch. It is rich in the carbohydrate inulin (76%), which is a polymer of the monosaccharide fructose. Tubers stored for any length of time will convert their inulin into its component fructose. Jerusalem artichokes have an underlying sweet taste because of the fructose, which is about one and a half times as sweet as sucrose.
Jerusalem artichokes have also been promoted as a healthy choice for type 2 diabetics, because fructose is better tolerated by people who are type 2 diabetic. It has also been reported as a folk remedy for diabetes.
