A medical assistant is educating a patient about the importance of dietary fiber. Which of the following is a primary benefit of adequate fiber intake?
- AReduced risk of osteoporosis
- BImproved blood glucose control
- CIncreased absorption of fat-soluble vitamins
- DEnhanced muscle growth and repair
Show answer & explanationAnswer & explanation
Correct answer: B. Improved blood glucose control
Dietary fiber, particularly soluble fiber, helps slow the absorption of sugar, which can improve blood glucose control, making it beneficial for individuals with diabetes or those at risk.
Why the other options are wrong
- A. Osteoporosis risk is reduced by adequate calcium and Vitamin D intake, not directly by fiber.
- C. Fat-soluble vitamin absorption is more related to fat intake, not primarily fiber.
- D. Muscle growth and repair are primarily linked to protein intake.
Dietary Fiber Benefits
Dietary fiber, indigestible plant material, is crucial for digestive health, blood sugar regulation, and cholesterol management.
- Two types: soluble and insoluble
- Promotes regular bowel movements
- Contributes to satiety
Memory trick: Fiber is a friend to your gut and your sugar levels.
