Question

All of the following are examples of Dietary fibre except :

• A. Pectin
• B. Lignin
• C. Cellulose
• D. Gums

Answer 1

The Correct Option is D

To determine which option is not an example of dietary fiber, we need to understand what dietary fiber is. Dietary fiber is a type of carbohydrate that the body cannot digest. It is found in the structural parts of plants and is categorized into soluble and insoluble fibers.

• Pectin: A type of soluble fiber found in fruits. It helps to slow gastric emptying and provide a feeling of fullness.
• Lignin: An insoluble fiber found in the woody parts of vegetables. It adds bulk to the stool and helps with bowel movements.
• Cellulose: An insoluble fiber that is a major component of plant cell walls, aiding in digestive health by adding bulk to stool.
• Gums: Although gums are soluble fibers used as thickeners in food processing, the context refers to dietary sources where gums are not typically recognized as dietary fiber in the same way as the others mentioned.

Upon evaluating the options, Gums are generally processed as thickeners and not traditionally recognized as a direct source of dietary fiber in a natural diet as compared to pectin, lignin, and cellulose. Thus, the correct answer is:

Gums
