Starches that supply carbohydrate polymers, as well as non-carbohydrate polymers which aid in digestion are known as:
**Core Concept**
The question is testing the concept of dietary fibers, which are complex carbohydrates that cannot be digested by the body but play a crucial role in promoting digestive health. Dietary fibers are classified into two main categories: soluble and insoluble fibers.
**Why the Correct Answer is Right**
The correct answer refers to polysaccharides and non-carbohydrate polymers, such as cellulose and lignin, which are found in plant cell walls and aid in digestion by promoting regular bowel movements, preventing constipation, and supporting the growth of beneficial gut bacteria. The soluble fibers, like pectin and guar gum, dissolve in water and form a gel-like substance that slows down the digestion and absorption of nutrients, while the insoluble fibers, like cellulose and hemicellulose, do not dissolve in water and help add bulk to stool.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify the type of polymers that aid in digestion.
**Option B:** This option is incorrect because it is too broad and does not specifically refer to dietary fibers.
**Option C:** This option is incorrect because it refers to a type of fiber, but not the polymers that aid in digestion.
**Clinical Pearl / High-Yield Fact**
It is essential to note that a high intake of dietary fibers can help prevent constipation, diverticulitis, and certain types of cancer, such as colon cancer.
**Correct Answer: C. Resistant Starches.**
