Which statement best describes soluble fiber?

• A. Does not dissolve and promotes regularity.
• B. Dissolves, but increases risk of diverticulitis.
• C. Dissolves, helps decrease cholesterol, regulates blood sugar, and increases weight loss.
• D. Dissolves, helps increase cholesterol.

Answer: (C)

Soluble fiber dissolves in water, forming a gel-like substance in the gut. This gel slows digestion, which helps regulate post-meal blood sugar levels and improves glycemic control. It also binds bile acids, lowering LDL cholesterol. Together, these effects can support weight management by increasing satiety and reducing overall energy intake. The statement that ties the dissolving property to these metabolic benefits best captures what soluble fiber does. In contrast, insoluble fiber is the one that doesn’t dissolve; claims about diverticulitis risk or increasing cholesterol don’t align with soluble fiber’s effects.
