1. The number of kilocalories provided by a food that contains 22g of fat is:

Correct answer: D

Rationale: The correct answer is D. Fat provides 9 kcal per gram, so 22 grams of fat will provide 198 kcal (22g * 9 kcal/g = 198 kcal). Choice A (88) is incorrect because it miscalculates the kcalories. Choice B (132) is incorrect as it does not consider the correct kcaloric value of fat. Choice C (154) is incorrect as it also does not calculate the kcalories accurately based on the fat content.

2. Major nutrients supplied by foods in the Vegetables group of MyPlate include:

Correct answer: A

Rationale: The correct answer is A: potassium and vitamin A. Vegetables are an excellent source of potassium and vitamin A, both essential for maintaining overall health. Iron and vitamin C (choice B) are commonly found in foods from the Protein and Fruits groups, respectively. Calcium and vitamin B12 (choice C) are more abundant in dairy products and animal-based foods. Sodium and vitamin E (choice D) are not the major nutrients typically supplied by vegetables.

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

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.

4. Which condition may benefit from branched chain amino acids (leucine, isoleucine, and valine)?

Correct answer: A

Rationale: Branched chain amino acids, such as leucine, isoleucine, and valine, are essential in preventing muscle breakdown. Therefore, they may be particularly important for a patient with cancer-related malnutrition, where maintaining muscle mass is crucial. Marasmus is a severe form of malnutrition characterized by energy deficiency, not specifically related to cancer. Cardiovascular disease and severe depression do not have a direct correlation with the need for branched chain amino acids to prevent muscle breakdown.

5. What are the compounds in soy foods with estrogen-like activity examples of?

Correct answer: B

Rationale: The correct answer is B: Phytochemicals. Phytochemicals in soy foods can mimic estrogen and may have health benefits. Indispensable amino acids are essential amino acids that the body cannot produce on its own. Neurotransmitters are chemical messengers in the nervous system. Metabolic by-products are substances produced during metabolism.
