Which type of fiber is primarily made up of cellulose?

Insoluble fiber is primarily made up of cellulose, a complex carbohydrate that forms the structural component of plant cell walls. This type of fiber is known for its ability to add bulk to the stool and help food move through the digestive system, which contributes to overall digestive health. Cellulose is not soluble in water, hence the classification of insoluble fiber. It does not dissolve in water or form gels, making it effective in preventing constipation and promoting regular bowel movements.

In contrast, soluble fiber, while beneficial for heart health and regulating blood sugar levels, is composed of different plant components such as pectins and gums. It dissolves in water and helps to slow digestion. Trans fats pertain to a type of unhealthy fat that can contribute to heart disease, while omega-3 fatty acids are a type of beneficial fat found in fish that promote heart health. Both trans fats and omega-3 fatty acids are unrelated to the fiber types discussed in this context.
