2. What is the approximate energy value of alcohol?
- A. 3 kcal/g
- B. 7 kcal/g
- C. 10 kcal/g
- D. 25 kcal/g
Correct answer: B: 7 kcal/g
Rationale: The correct answer is B: 7 kcal/g. Alcohol provides approximately 7 kilocalories per gram, making it a significant source of energy or 'empty calories' in the diet that do not contain any nutrients. 'Empty calories' refer to the calorie content without the presence of essential nutrients. Choices A, C, and D are incorrect. The energy values of 3 kcal/g, 10 kcal/g, and 25 kcal/g are not accurate for alcohol; instead, they may pertain to other nutrients such as carbohydrates (approximately 4 kcal/g), fats (approximately 9 kcal/g), and oils (approximately 9 kcal/g).

The other choices provided, low income, vegans, and chronic disease, alcoholics, are also at risk for nutritional deficiencies but the question specifically asks for 4 groups out of the 12 discussed. The 12 groups at risk for nutritional deficiencies include the elderly, low income individuals, vegans, chronic disease, alcoholics, smokers, periods of growth, individuals with medical conditions, physical stress, physiological stress, those on polypharmacy, and those with inadequate intake. The question focuses on identifying 4 out of these 12 groups, making 'Elderly' the correct choice.

Correct answer: D
Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.
5. Each of the following nutrients provides energy except one. Which one is the exception?
- A. Proteins
- B. Carbohydrates
- C. Fats

Rationale: The correct answer is D, Vitamins. While proteins, carbohydrates, and fats provide energy, vitamins do not. Vitamins are essential micronutrients that help regulate various biochemical processes in the body, such as metabolism and immunity. Choice A, B, and C are incorrect because proteins, carbohydrates, and fats are macronutrients that the body uses as a source of energy.
