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

• A. potassium and vitamin A.
• B. iron and vitamin C.
• C. calcium and vitamin B12.
• D. sodium and vitamin E.

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.

2. For a healthy person, what percentage of daily calories should be supplied by protein?

• A. 5% to 10%.
• B. 10% to 35%.
• C. more than 25%.
• D. more than 35%.

Correct answer: B

Rationale: The correct answer is B: 10% to 35%. For a healthy person, it is recommended that 10% to 35% of their daily caloric intake should come from protein. This range ensures an adequate intake of protein for various bodily functions without overdoing it. Choices A, C, and D are incorrect because they suggest percentages either below the recommended range (A, C) or exceeding it (D), which could lead to nutritional imbalances or health issues.

3. Which types of acids form the basic building blocks of protein?

• A. fatty
• B. amino
• C. nucleic
• D. omega fatty

Correct answer: B

Rationale: The correct answer is 'B: amino.' Amino acids are the fundamental units that make up proteins. They are essential for various bodily functions, including building and repairing tissues. Choice A, 'fatty acids,' are not the basic building blocks of proteins but rather a type of lipid. Choice C, 'nucleic acids,' are the building blocks of nucleic acids like DNA and RNA, not proteins. Choice D, 'omega fatty acids,' are a specific type of fatty acid known for their health benefits but are not directly related to the building blocks of proteins.

4. The major focus of nutritional recommendations in this century has shifted to:

• A. prevention and control of chronic diseases.
• B. improved sanitation and public health.
• C. prevention and control of infectious diseases.
• D. development of healthful foods using food technology.

Correct answer: A

Rationale: The correct answer is A: prevention and control of chronic diseases. In this century, nutritional recommendations have increasingly emphasized the importance of preventing and managing chronic diseases like obesity, diabetes, cardiovascular diseases, and cancer. Lifestyle factors such as diet play a significant role in the development of these conditions. Option B, improved sanitation and public health, although important for overall health, is not the primary focus of nutritional recommendations. Option C, prevention and control of infectious diseases, is also crucial but does not reflect the current major focus of nutritional recommendations. Option D, development of healthful foods using food technology, is a valid area of interest but is not the primary shift in focus observed in nutritional recommendations.

5. What is one function of essential fatty acids?

• A. improve skin integrity.
• B. control lipid digestion.
• C. reduce blood clotting time.
• D. form chylomicrons.

Correct answer: A

Rationale: Essential fatty acids play a crucial role in improving skin integrity by supporting the structure and function of cell membranes. This helps in maintaining healthy skin and promoting overall well-being. The other choices are incorrect because essential fatty acids do not directly control lipid digestion, reduce blood clotting time, or form chylomicrons.
