what are soluble / insoluble fibre

Soluble and insoluble fiber are two types of dietary fiber that play important roles in maintaining a healthy digestive system.

Soluble fiber dissolves in water and forms a gel-like substance in the digestive tract. This type of fiber can be found in foods such as oats, legumes, fruits (such as apples and oranges), and vegetables (such as carrots). When digested, soluble fiber helps slow down the digestion process and can help regulate blood sugar levels and lower cholesterol.

Insoluble fiber, on the other hand, does not dissolve in water and adds bulk to the stool. It can be found in foods such as whole grain products, wheat bran, nuts, and seeds. Insoluble fiber helps promote regular bowel movements by aiding in the movement of food through the digestive system.

To determine whether a particular type of fiber is soluble or insoluble, you can perform a simple experiment at home:

1. Start with a glass of water.
2. Take a small amount of the fiber you want to test and add it to the glass of water.
3. Stir the mixture for a few seconds.
4. Observe whether the fiber dissolves completely in the water (soluble) or remains intact (insoluble).

This experiment can help you gain a better understanding of the properties of different types of fiber and how they interact with water. It's important to note that some fibers may have both soluble and insoluble characteristics, so the distinction may not always be clear-cut.
