What are the components of soluble fiber?

The components of soluble fiber include pectin and gums, which are both polysaccharides that dissolve in water. Soluble fiber is known for its ability to form a gel-like substance in the digestive tract, which can help lower cholesterol levels and stabilize blood sugar levels.

Pectin is commonly found in fruits and contributes to the thickening process in jelly and jams. Gums, which are derived from seeds and plants, play a crucial role in food stabilization and can enhance texture in various food products.

The other choices represent different types of carbohydrates. Amylose and amylopectin are components of starch, primarily found in grains and tubers, while cellulose and lignin are components of insoluble fiber, responsible for adding bulk to the diet and aiding in digestive health. Inulin and resistant starch are indeed fibers, but they fall under the category of soluble and insoluble fibers; however, they do not specifically capture the classic definitions and examples of soluble fiber as pectin and gums do.
