Soluble dietary fiber refers to a type of dietary fiber that is dissolved in water or liquid. It can be found in certain foods such as oats, barley, fruits like apples and pears, and vegetables like carrots and green peas. Soluble dietary fibre has several health benefits including promoting regular bowel movements, reducing cholesterol levels by binding to bile acids in the intestines, slowing down digestion which can help control blood sugar levels, and providing a feeling of fullness after eating.
