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. The function of Dietary Reference Intakes (DRIs) is to designate nutrient recommendations for:

• A. different ethnic groups.
• B. all individuals.
• C. most people.
• D. most healthy people.

Correct answer: D

Rationale: The correct answer is D. Dietary Reference Intakes (DRIs) are established to provide nutrient recommendations for most healthy people. They are not specific to different ethnic groups (choice A), all individuals (choice B), or most people (choice C). DRIs aim to prevent nutrient deficiencies and chronic diseases in healthy individuals by setting intake levels for various nutrients.

3. The lining of the stomach and intestine is protected from self-digestion by:

• A. pepsinogen.
• B. bile.
• C. mucus.
• D. fat.

Correct answer: C

Rationale: The correct answer is C: mucus. Mucus forms a protective barrier that prevents the stomach and intestine from digesting themselves. Pepsinogen (choice A) is an inactive form of pepsin, a digestive enzyme, and does not protect the stomach lining. Bile (choice B) aids in the digestion and absorption of fats but does not protect the stomach lining. Fat (choice D) is a nutrient and energy source; it does not play a role in protecting the stomach and intestine from self-digestion.

4. Which of the following is a characteristic of essential fatty acids?

• A. They can come from both animal and plant sources.
• B. They are not manufactured by the body.
• C. They are not manufactured by the body.
• D. They are manufactured by the body.

Correct answer: B

Rationale: The correct answer is B: Essential fatty acids are not manufactured by the body. These fatty acids must be obtained through the diet because the body cannot synthesize them. Choice A is incorrect because essential fatty acids can come from both animal and plant sources, not just from an animal source. Choice C is the correct characteristic of essential fatty acids. Choice D is incorrect because essential fatty acids are not produced by the body.

5. The sum of all chemical processes inside living cells of the body that sustain life and health is known as:

• A. physiology
• B. digestion
• C. metabolism
• D. nutrition

Correct answer: C

Rationale: Metabolism is the correct answer as it refers to the sum of all chemical processes that occur within living cells to maintain life and health. Physiology (Choice A) is the study of how living organisms function but does not specifically refer to cellular chemical processes. Digestion (Choice B) is the process of breaking down food in the body, not the overall cellular processes. Nutrition (Choice D) is the process of obtaining and consuming food necessary for health and growth, but it does not encompass all cellular processes related to sustaining life and health.
