1. Does the reduction in oxidative damage that occurs with energy restriction in animals also occur in people whose diets include _____?
- A. fiber and carbohydrates
- B. fatty acids and protein
- C. probiotics
- D. antioxidants and phytochemicals
Correct answer: D
Rationale: The correct answer is 'antioxidants and phytochemicals'. Antioxidants and phytochemicals help reduce oxidative damage in the body, contributing to healthy aging and a lower risk of chronic diseases. This is the same effect observed in animals when their energy intake is restricted. The other choices are incorrect as there is no direct evidence connecting reduced oxidative damage with diets high in fiber and carbohydrates, fatty acids and protein, or probiotics.
2. Patients with congestive heart failure need to restrict their intake of:
- A. fiber
- B. sodium
- C. cholesterol
- D. saturated fat
Correct answer: B
Rationale: Patients with congestive heart failure need to restrict their intake of sodium. This restriction is crucial to prevent fluid retention, which can exacerbate the condition. While fiber is generally beneficial for heart health, sodium restriction is more critical in this scenario. Cholesterol and saturated fat intake should also be monitored, but sodium restriction takes precedence due to its direct impact on fluid balance.
3. How many amino acids are essential?
- A. 5
- B. 7
- C. 9
- D. 13
Correct answer: C
Rationale: The correct answer is C: 9. There are 9 essential amino acids that the body cannot synthesize and must be obtained through the diet. These 9 amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices A, B, and D are incorrect as they do not represent the correct number of essential amino acids.
4. Risk factors that have been shown to contribute to age-related macular degeneration include _____.
- A. oxidative stress from sunlight
- B. iron-deficiency anemia
- C. decreased intake of phytochemicals
- D. vitamin B6 malabsorption
Correct answer: A
Rationale: The correct answer is A: oxidative stress from sunlight. Oxidative stress caused by exposure to sunlight is a significant risk factor for age-related macular degeneration. This condition can result in vision loss among older individuals. Choices B, C, and D are incorrect. Iron-deficiency anemia, decreased intake of phytochemicals, and vitamin B6 malabsorption are not established risk factors for age-related macular degeneration.
5. Which gluten-free food choice would be most appropriate for a patient with celiac disease?
- A. Scalloped potatoes
- B. Oatmeal
- C. Eggs
- D. Tortillas
Correct answer: C
Rationale: Eggs are a safe food choice for individuals with celiac disease as they are naturally gluten-free. Scalloped potatoes often contain flour in the sauce, which might contain gluten. Oatmeal can be a subject of debate due to possible cross-contamination during processing, so it might not be safe unless labeled gluten-free. Tortillas are typically made from wheat flour containing gluten, but gluten-free versions are available. However, eggs are universally gluten-free, making them the best choice for individuals with celiac disease.
