What does the term "soluble fiber" refer to?

The term "soluble fiber" refers to a type of dietary fiber that dissolves in water. This characteristic is significant because soluble fiber can form a gel-like substance in the digestive system, which can help slow down digestion and the absorption of glucose. This property is beneficial for controlling blood sugar levels and can aid in lowering cholesterol levels by binding to cholesterol and bile acids in the gut, thus promoting heart health.

Understanding the nature of soluble fiber is important in nutrition, as it has various health benefits, such as improving gut health and aiding in weight management. Foods rich in soluble fiber include oats, legumes, nuts, apples, and citrus fruits, among others. Knowing the role of different types of fiber in a balanced diet is crucial for making informed dietary choices.
