Which of the following is a type of soluble fiber?

Oats are classified as a type of soluble fiber due to their high content of beta-glucans, which are specific types of soluble fibers known to have beneficial effects on heart health and cholesterol levels. Soluble fiber dissolves in water to form a gel-like substance in the digestive tract, which can help to slow down digestion and improve nutrient absorption. This type of fiber is particularly beneficial for managing blood sugar levels and promoting a feeling of fullness.

In contrast, wheat bran is primarily composed of insoluble fiber, which adds bulk to the stool and helps promote regular bowel movements. Corn and potatoes also contain primarily insoluble fiber, contributing to digestive health but lacking the specific soluble fiber characteristics found in oats. Thus, oats stand out in this context due to their unique soluble fiber content and associated health benefits.
