The proportion of adults who use exercise and diet to reduce body weight has declined. The proportion of the population who meet recommendations for consumption of calcium-rich foods has decreased, and the lowest proportion is among adolescent and young adult females. Prevalence of iron deficiency has also increased among young adult females. Diabetes is increasing, as well. Jerusalem artichokes contain inulin, a fructose polysaccharide, a sort of starch, that is present in the tuber or rhizome of the plant.
Fructose polysaccharide means it is a long chain of fructose units connected together.
Upon digestion it breaks down into individual fructose units. Consumers may be confusing inulin and insulin. Neither Jerusalem artichokes, also known as sun chokes, nor any other plants contain insulin. It's hard to say at this point. The main advantage of fructose is that it is absorbed somewhat more slowly than glucose.
