1. The release of gastric secretions is stimulated by nerve and hormonal stimuli and the:

• A. ingestion of water.
• B. swallowing reflex.
• C. presence of food in the stomach.
• D. closing of the pyloric sphincter.

Correct answer: C

Rationale: The correct answer is C: 'presence of food in the stomach.' Gastric secretions are stimulated when food enters the stomach, triggering nerve and hormonal responses. This process prepares the stomach for digestion. Choices A, B, and D are incorrect because ingesting water, swallowing reflex, and the closing of the pyloric sphincter do not directly stimulate the release of gastric secretions.

2. Which of the following sugars tastes the sweetest?

• A. Glucose
• B. Sucrose
• C. Galactose
• D. Fructose

Correct answer: D

Rationale: Fructose is known to be the sweetest among naturally occurring sugars. While glucose, sucrose, and galactose also have sweet tastes, fructose is commonly perceived as the sweetest due to its higher level of sweetness. Glucose is a simple sugar found in many carbohydrates; sucrose is table sugar composed of glucose and fructose; galactose is a component of lactose found in dairy products. However, when comparing the sweetness levels of these sugars, fructose stands out as the sweetest.

3. To prevent symptoms of fatigue, dehydration, and energy loss, what is the daily recommended minimum intake of carbohydrates?

• A. 130 g.
• B. 230 g.
• C. 330 g.
• D. 430 g.

Correct answer: A

Rationale: The correct answer is A: 130 g. The recommended minimum intake of carbohydrates to prevent fatigue, dehydration, and energy loss is 130 grams per day. Consuming an adequate amount of carbohydrates provides the body with energy and helps prevent symptoms associated with insufficient carbohydrate intake. Choices B, C, and D are incorrect as they suggest higher amounts of carbohydrate intake, which may not necessarily align with the recommended daily minimum intake for preventing symptoms of fatigue, dehydration, and energy loss.

4. Where are sugar alcohols most likely to be found?

• A. Fermented foods.
• B. Low-calorie foods.
• C. Fruits and vegetables.
• D. Fiber supplements.

Correct answer: B

Rationale: Sugar alcohols are commonly found in low-calorie foods as sweetening agents without the calorie content of regular sugars. Choices A, C, and D are incorrect because sugar alcohols are not typically found in fermented foods, fruits, vegetables, or fiber supplements. Therefore, the correct answer is B.

5. 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

Rationale: The correct answer is A: 'mostly found in animal products.' Saturated fats are primarily found in animal products such as meat, dairy, and eggs. 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. Choice D is incorrect because saturated fats are mainly found in animal products, not vegetable products.
