A
Helps regulate blood sugar levels
B
Aids in the absorption of vitamins
C
Provides a direct source of energy
D
Increases cholesterol levels
Verified step by step guidance1
Understand the role of dietary fiber in the human body. Dietary fiber is a type of carbohydrate that the body cannot digest. It is found in plant-based foods such as fruits, vegetables, whole grains, and legumes.
Recognize that dietary fiber is classified into two types: soluble and insoluble. Soluble fiber dissolves in water to form a gel-like substance, which can help regulate blood sugar levels by slowing down the absorption of sugar.
Consider the function of soluble fiber in regulating blood sugar levels. By slowing the absorption of sugar, soluble fiber helps prevent spikes in blood glucose levels, which is beneficial for maintaining stable energy levels and managing diabetes.
Evaluate the other options provided: Aids in the absorption of vitamins, Provides a direct source of energy, and Increases cholesterol levels. Dietary fiber does not aid in the absorption of vitamins; rather, it can bind to certain minerals and reduce their absorption. It does not provide a direct source of energy because it is not digested by the body. Instead, it can help with satiety and digestive health. Fiber does not increase cholesterol levels; in fact, soluble fiber can help lower cholesterol levels by binding to cholesterol particles and removing them from the body.
Conclude that the primary function of dietary fiber related to the options given is its ability to help regulate blood sugar levels, making it an important component of a balanced diet for maintaining overall health.
