Which of the following is NOT a function of dietary fiber?
Aids in digestion
Raises blood sugar quickly
Promotes bowel regularity
Helps control cholesterol
Which of the following is a source of dietary fiber?
Chicken breast
Apple skin
Butter
Cheese
A person consumes a meal high in simple sugars. Predict and explain the likely short-term effect on their blood glucose levels, and suggest a dietary strategy to minimize rapid spikes.
Blood glucose will decrease; eat more protein
Blood glucose will spike quickly; combine with fiber-rich foods
Blood glucose will remain unchanged; avoid all carbohydrates
Blood glucose will slowly rise; increase fat intake
Given a list of foods—white bread, lentils, orange juice, and oatmeal—rank them from highest to lowest expected impact on blood sugar levels, and justify your ranking.
Orange juice > white bread > oatmeal > lentils; based on glycemic index
Lentils > oatmeal > white bread > orange juice; based on fiber content
White bread > orange juice > oatmeal > lentils; based on glycemic index
Oatmeal > lentils > orange juice > white bread; based on sugar content
A patient with lactose intolerance experiences discomfort after consuming dairy. Using your knowledge of carbohydrate digestion, explain the cause and recommend an alternative.
Lack of lactase enzyme; choose lactose-free milk
Excess amylase; eat more cheese
Too much fiber; switch to yogurt
High sucrose intake; avoid all sugars
Analyze why whole grains are generally considered healthier carbohydrate sources compared to refined grains.
They contain more protein
They have higher fiber and nutrient content
They are lower in calories
They digest faster
A diabetic individual must manage their carbohydrate intake. Propose a meal plan modification to help maintain stable blood sugar levels, using evidence from carbohydrate digestion and absorption.
Replace all carbohydrates with fats
Choose high-fiber, low-glycemic foods and spread intake throughout the day
Eat only simple sugars for quick energy
Skip meals to reduce carbohydrate intake
Evaluate the impact of consuming a high-fiber diet on the risk of developing type 2 diabetes, using scientific reasoning.
Increases risk by raising blood sugar
Decreases risk by slowing glucose absorption
No effect on diabetes risk
Increases risk by reducing insulin production
A person eats a meal containing both starch and fiber. Explain how the digestion and absorption of these carbohydrates differ, and the implications for energy release.
Both are digested quickly, leading to rapid energy release
Starch is digested and absorbed; fiber is not digested, leading to slower energy release
Fiber is digested first, then starch
Neither is digested, so no energy is released
Given a scenario where a person consumes only simple carbohydrates for breakfast, predict the effect on their energy levels throughout the morning and justify your answer.
Sustained energy due to slow digestion
Quick spike in energy followed by a crash as blood sugar drops
No change in energy levels
Gradual increase in energy
Compare the effects of soluble and insoluble fiber on digestive health and blood sugar regulation, providing evidence for your answer.
Both types raise blood sugar rapidly
Soluble fiber slows glucose absorption; insoluble fiber promotes bowel movement
Insoluble fiber increases cholesterol; soluble fiber has no effect
Both types are digested and absorbed for energy
A nutritionist is designing a diet for athletes requiring sustained energy. Using your understanding of carbohydrate types and digestion, recommend the best carbohydrate sources and explain your reasoning.
Simple sugars for quick energy
Complex carbohydrates like whole grains for gradual energy release
Only protein sources
High-fat foods for energy
