Final answer:
Both A and B are true regarding the potential benefits of dietary fiber.
Step-by-step explanation:
The correct statement regarding the potential benefits of dietary fiber is Both A and B.
Dietary fiber, specifically soluble fiber, has been shown to lower LDL cholesterol levels. It forms a gel-like substance in the gastrointestinal tract, which can help trap cholesterol and prevent it from being absorbed into the bloodstream.
Additionally, soluble fiber can reduce postprandial blood glucose levels. It slows down the absorption of glucose from the digestive system into the bloodstream, resulting in more stable blood sugar levels.
