Superfoods Risk Assessment & Management 3 — Questions and Answers
Question 1: Which superfood is most associated with the risk of vitamin A toxicity when consumed in high amounts?
- Spinach
- Liver (organ meat) (Correct answer)
- Blueberries
- Quinoa
Correct answer: Liver (organ meat)
Liver is extremely rich in preformed vitamin A (retinol), and frequent high consumption can lead to hypervitaminosis A.
Question 2: A person with a shellfish allergy is at elevated risk for adverse reactions to which superfood?
- Chia seeds
- Spirulina
- Glucosamine from shellfish (Correct answer)
- Flaxseeds
Correct answer: Glucosamine from shellfish
Glucosamine supplements are often derived from shellfish shells and can trigger allergic reactions in people with shellfish allergies.
Question 3: What risk does excessive consumption of Brazil nuts pose due to their superfood nutrient profile?
- Iron overload
- Selenium toxicity (selenosis) (Correct answer)
- Zinc deficiency
- Copper toxicity
Correct answer: Selenium toxicity (selenosis)
Brazil nuts are extraordinarily high in selenium, and eating more than a few per day can cause selenosis with symptoms like hair loss and neurological issues.
Question 4: Which risk assessment consideration is most important before recommending high-dose omega-3 fish oil supplements?
- History of lactose intolerance
- History of bleeding disorders or anticoagulant use (Correct answer)
- Gluten sensitivity
- Caffeine sensitivity
Correct answer: History of bleeding disorders or anticoagulant use
High-dose omega-3s have blood-thinning effects that can be hazardous for those with bleeding disorders or taking anticoagulant medications.
Question 5: What is the primary contamination risk associated with wild-harvested superfoods like goji berries from certain regions?
- Natural toxin production
- Heavy metal contamination from soil (Correct answer)
- Prion disease transmission
- Antibiotic residues
Correct answer: Heavy metal contamination from soil
Wild-harvested and imported superfoods like goji berries may accumulate heavy metals such as lead, arsenic, or cadmium from contaminated soils.
Question 6: Why is chlorella supplementation a specific risk for individuals taking warfarin?
- Chlorella contains high vitamin K which antagonizes warfarin (Correct answer)
- Chlorella increases warfarin absorption
- Chlorella depletes vitamin C which warfarin needs
- Chlorella causes kidney damage reducing warfarin clearance
Correct answer: Chlorella contains high vitamin K which antagonizes warfarin
Chlorella is rich in vitamin K, which directly counteracts the anticoagulant effect of warfarin and can lead to blood clotting complications.
Question 7: Which risk is most relevant when assessing cacao/dark chocolate as a superfood for children?
- High vitamin D toxicity risk
- Caffeine and theobromine sensitivity causing agitation or sleep issues (Correct answer)
- Excess fiber causing intestinal blockage
- Oxalate-driven tooth decay
Correct answer: Caffeine and theobromine sensitivity causing agitation or sleep issues
Cacao contains caffeine and theobromine, stimulants that children metabolize more slowly, increasing risk of agitation, elevated heart rate, and disrupted sleep.
