1. How do foods or supplements containing significant amounts of plant sterols help lower LDL cholesterol levels?

• A. reducing cholesterol synthesis
• B. suppressing inflammation
• C. reducing blood clotting
• D. interfering with cholesterol and bile absorption

Correct answer: D

Rationale: Plant sterols interfere with cholesterol and bile absorption in the intestines. This interference helps lower LDL cholesterol levels by reducing the amount of cholesterol that enters the bloodstream. Choices A, B, and C are incorrect because plant sterols primarily work by interfering with cholesterol and bile absorption, not by reducing cholesterol synthesis, suppressing inflammation, or reducing blood clotting.

2. Dietary fiber has been recommended for its possible benefits in reducing heart disease by lowering blood cholesterol. How is fiber thought to play its role in lowering blood cholesterol?

• A. Insoluble fiber binds with cholesterol in the large intestine and is excreted in feces
• B. Viscous fiber binds with bile in the intestine and is excreted in feces
• C. Soluble fiber binds with cholesterol in the blood and is excreted by the liver
• D. Insoluble fiber converts to bile in the large intestine and binds with cholesterol

Correct answer: B

Rationale: The correct answer is B. Viscous (soluble) fiber binds with bile acids in the intestine, which are then excreted. The liver must use cholesterol to make more bile acids, thereby lowering blood cholesterol levels. Choice A is incorrect as insoluble fiber does not bind with cholesterol in the large intestine. Choice C is incorrect as soluble fiber does not directly bind with cholesterol in the blood. Choice D is incorrect as insoluble fiber does not convert to bile in the large intestine to bind with cholesterol.

3. Loss of smell results in a condition that limits the capacity to detect the flavor of food and beverages, called:

• A. hypergeusia
• B. dysgeusia
• C. anosmia
• D. phantom taste

Correct answer: C

Rationale: The correct answer is C: anosmia. Anosmia refers to the loss of smell, which significantly affects the ability to detect flavors. Hypergeusia and dysgeusia, choices A and B, refer to heightened or distorted taste, respectively. 'Phantom taste' in choice D is not the correct term for the condition described in the question.

4. A patient with an ileostomy is suffering from frequent diarrhea. The clinician should advise the patient to increase his intake of what food to thicken stool output?

• A. celery
• B. salad greens
• C. potatoes
• D. dried beans and peas

Correct answer: C

Rationale: Potatoes are starchy and can help thicken stool output, making them beneficial for patients with an ileostomy experiencing diarrhea.

5. Does alcohol contain energy and is therefore a nutrient?

• A. True
• B. False
• C.
• D.

Correct answer: B

Rationale: Alcohol does contain energy and provides calories, but it is not considered a nutrient. Nutrients are substances that contribute to essential bodily functions. While alcohol may have energy, it does not provide essential vitamins, minerals, or other nutrients necessary for the body's health. Additionally, excessive alcohol consumption can have harmful effects on the body, further supporting why alcohol is not classified as a nutrient.
