1. A person with lactose intolerance should be most careful to limit their intake of:

• A. milk
• B. yogurt
• C. cheese
• D. corn syrup

Correct answer: A

Rationale: Individuals with lactose intolerance lack the enzyme lactase needed to break down lactose, the sugar in dairy products. Milk contains a high amount of lactose, making it crucial for those with lactose intolerance to limit their intake. Yogurt and cheese, on the other hand, have lower lactose content due to the fermentation process which reduces lactose levels, making them better tolerated by many with lactose intolerance. Corn syrup, although high in sugar, does not contain lactose and is unrelated to lactose intolerance. Therefore, the correct answer is 'milk' as it is a significant source of lactose, which can trigger symptoms in individuals with lactose intolerance.

2. Which phase of metabolism makes growth and repair possible?

• A. digestion
• B. catabolism
• C. anabolism
• D. ketosis

Correct answer: C

Rationale: Anabolism is the phase of metabolism responsible for building up and repairing tissues in the body. It involves processes that require energy to synthesize complex molecules from simpler ones. Digestion (choice A) is the process of breaking down food into simpler substances for absorption. Catabolism (choice B) involves the breakdown of complex molecules into simpler ones with the release of energy. Ketosis (choice D) is a metabolic state where the body uses fat as the primary source of energy, which is not directly related to growth and repair.

3. Which of the following sandwiches is high in saturated fatty acids?

• A. Tuna salad
• B. Grilled cheese
• C. Turkey and sprouts
• D. Peanut butter and jelly

Correct answer: B

Rationale: The correct answer is Grilled cheese because it is high in saturated fatty acids due to the dairy fat content in cheese. Tuna salad, turkey and sprouts, and peanut butter and jelly do not contain as high levels of saturated fatty acids as grilled cheese. Tuna salad typically contains mayonnaise which may contribute to some saturated fat content, but it is generally lower compared to the cheese in grilled cheese. Turkey and sprouts are leaner options, while peanut butter and jelly are higher in unsaturated fats rather than saturated fats.

4. What group makes each amino acid unique?

• A. Radical group
• B. Amino group
• C. Carboxyl group
• D. Peptide bond

Correct answer: A

Rationale: The correct answer is the radical group (R-group) because it is the unique side chain that differentiates each amino acid. The amino group (choice B) and carboxyl group (choice C) are functional groups common to all amino acids but do not make them unique. The peptide bond (choice D) is the bond formed between amino acids in a protein chain, not the group that makes each amino acid unique.

5. Signs of malnutrition can appear when:

• A. nutrient reserves are depleted.
• B. nutrient intake exceeds daily needs.
• C. energy intake is restricted.
• D. caloric expenditure increases.

Correct answer: A

Rationale: The correct answer is A: 'nutrient reserves are depleted.' Signs of malnutrition manifest when the body's reserves of essential nutrients are exhausted and can no longer sustain health. Choice B is incorrect because excessive nutrient intake exceeding daily needs does not lead to malnutrition but may cause other health issues. Choice C is incorrect as restricting energy intake may lead to weight loss but not necessarily malnutrition. Choice D is also incorrect as increasing caloric expenditure does not directly cause malnutrition.
