1. A vegetarian diet that includes dairy foods and eggs is known as:

• A. lactovegetarian.
• B. vegan.
• C. semi-vegetarian.
• D. ovolactovegetarian.

Correct answer: D

Rationale: The correct term for a vegetarian diet that includes both dairy foods and eggs is 'ovolactovegetarian.' This term specifically indicates the inclusion of eggs ('ovo') and dairy ('lacto') in the diet. Choice A, 'lactovegetarian,' is incorrect because it only includes dairy products without eggs. Choice B, 'vegan,' is incorrect as it excludes all animal products, including dairy and eggs. Choice C, 'semi-vegetarian,' is incorrect as it is a term used for individuals who occasionally eat meat, poultry, or fish but primarily follow a plant-based diet.

2. Which nutrient group provides the primary source of energy for the body?

• A. Carbohydrates.
• B. Fats.
• C. Proteins.
• D. Vitamins.

Correct answer: A

Rationale: Carbohydrates are the body's primary source of energy. When carbohydrates are consumed, they are broken down into glucose, which is used by the body's cells for energy production. Fats and proteins are also essential nutrients, but carbohydrates are the preferred energy source for the body due to their quick conversion into fuel. Vitamins are not a direct source of energy but play crucial roles in various bodily functions.

3. A protein that contains all the essential amino acids in the proper proportions is called:

• A. simple
• B. indispensable
• C. complete
• D. complementary

Correct answer: C

Rationale: A complete protein is the term used to describe a protein that contains all the essential amino acids required by the body in the right proportions. This makes choice C the correct answer. Choice A, 'simple,' is incorrect as it does not reflect the concept of essential amino acids. Choice B, 'indispensable,' while related to importance, does not specifically address the presence of all essential amino acids. Choice D, 'complementary,' is also incorrect as it refers to combining proteins to achieve a complete amino acid profile, rather than describing a protein that already contains all essential amino acids.

4. What is the function of chylomicrons?

• A. Produced in the hepatic system.
• B. Composed of triglycerides and cholesterol only.
• C. Absorbed in the large intestine.
• D. Cleared from the blood by lipoprotein lipase.

Correct answer: D

Rationale: Chylomicrons are particles that transport dietary fats from the small intestine to cells in the body. They are cleared from the bloodstream by lipoprotein lipase, an enzyme that breaks down triglycerides in chylomicrons into fatty acids and glycerol. This process allows fats to be absorbed by the body. Choices A, B, and C are incorrect because chylomicrons are not formed in the hepatic system, they are composed of various lipids including triglycerides and cholesterol, and they are absorbed in the small intestine, not the large intestine.

5. Exchange Lists for Meal Planning was originally intended as a meal-planning tool for people who have:

• A. cancer.
• B. diabetes.
• C. hypertension.
• D. heart disease.

Correct answer: B

Rationale: The correct answer is B: diabetes. Exchange Lists for Meal Planning were originally created to assist individuals with diabetes in managing their diet by providing a structured approach to balanced food exchanges. This system helps individuals regulate their blood sugar levels and maintain overall health. Choices A, C, and D are incorrect because Exchange Lists for Meal Planning were not primarily developed for individuals with cancer, hypertension, or heart disease.
