Which of the following is a characteristic of soluble fiber?
A. Dissolves in stomach fluids
B. Is not a source of calories
C. Speeds up the movement of waste
D. Provides bulk for stool formation
The Correct Answer and Explanation is :
The correct answer is A. Dissolves in stomach fluids.
Explanation:
Soluble fiber is a type of dietary fiber that can dissolve in water to form a gel-like substance. This characteristic distinguishes it from insoluble fiber, which does not dissolve in water and primarily adds bulk to the stool. Soluble fiber can be found in various foods, including oats, legumes, fruits (like apples and citrus), and vegetables (such as carrots and Brussels sprouts).
When soluble fiber is consumed, it undergoes fermentation in the digestive tract, leading to the production of short-chain fatty acids that provide several health benefits. One of the most notable benefits of soluble fiber is its ability to help regulate blood sugar levels. By slowing the absorption of sugar, soluble fiber can help prevent spikes in blood glucose, making it particularly beneficial for individuals with diabetes or those at risk of developing the condition.
Additionally, soluble fiber plays a crucial role in lowering cholesterol levels. The gel-like substance formed when soluble fiber dissolves in water can bind to cholesterol in the intestines, preventing its absorption into the bloodstream. This process can lead to lower overall cholesterol levels, thus reducing the risk of cardiovascular diseases.
While it is true that soluble fiber contributes some calories to the diet, its caloric content is lower than that of other macronutrients. It is not accurate to say that it is “not a source of calories.” Furthermore, soluble fiber does not speed up the movement of waste; that characteristic is more associated with insoluble fiber, which helps to bulk up the stool and promote regular bowel movements.
In summary, soluble fiber’s ability to dissolve in stomach fluids allows it to provide various health benefits, including improved blood sugar regulation and lower cholesterol levels.
