Fiber is an essential part of a healthy diet and vital for your body to function properly. fiber helps the digestive system to process food and absorb nutrients. However, it is not something the body can absorb - this means that it is not a nutrient and contains no vitamins.
Fiber is obtained from plant-based foods. There are two types of fiber: insoluble and soluble.
Insoluble Fiber
Insoluble fiber contains the compounds cellulose, hemicellulose and lignin. These help the bowel to pass food by making stools soft and bulky. This type of fiber helps prevent constipation.
