A characteristic of saturated fats is that they are:
- A. mostly found in animal products.
- B. solid at room temperature.
- C. composed of many double bonds.
- D. found primarily in vegetable products.
Correct Answer: A

They are typically solid at room temperature. Choice B is incorrect because saturated fats are solid at room temperature, not liquid. Choice C is incorrect because saturated fats do not have double bonds; they have single bonds between carbon atoms.

Which monosaccharide only occurs naturally in foods in combination with another sugar as a disaccharide?
- A. Fructose.
- B. Galactose.
- C. Sucrose.
- D. Maltose.
Correct Answer: B
Rationale: The correct answer is B, galactose. Galactose naturally occurs in foods only when it is combined with glucose to form lactose, a disaccharide found in milk.

Maltose is a disaccharide formed by the combination of two glucose molecules.
Consuming 30 g of which nutrient would provide the highest number of kcalories?
- A. Carbohydrates
- B. Fat
- C. Protein
- D. Micronutrients
Correct Answer: B
Rationale: The correct answer is B, 'Fat.' Fat provides 9 kcalories per gram, which is more than carbohydrates and proteins that provide 4 kcalories per gram each. Therefore, consuming 30 g of fat would yield a higher number of kcalories compared to the same amount of carbohydrates or proteins. Micronutrients do not significantly contribute to kcalories, making them an incorrect choice in this scenario.
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.
