Inulin is a starchy substance found in a wide variety of fruits and vegetables such as wheat, onions, bananas, leeks, artichokes, and asparagus. #Inulin can be used to increase the dietary fiber content. Dietary fibers are essential in our daily food, but our diets rarely contain enough of them. The average adult should consume about 25-30 grams a day. Few of us actually eat more than 15-20 grams daily. As a soluble dietary fiber, inulin has many benefits. Make healthy products that remain amazing in tasty white bread with extra fiber, sugar-reduced bakery goods or lower-fat spoonable yogurt.
