QUESTION TYPE: Most Strongly Supported
- You should not greatly exceed the recommended daily intake (RDA) of vitamins A and D – they are toxic.
- Some vitamin fortified foods have 100% of the daily intake of those vitamins per serving.
- Many people eat 2-3x the standard servings of some vitamin fortified foods.
ANALYSIS: We know “some” vitamin fortified cereals have 100% of the RDA. It’s a warranted assumption that other vitamin fortified cereals have a significant percent of the RDA, say 30-50%.
We know some people eat 2-3x the recommended serving. And it’s a warranted assumption that people get vitamin A and D from other food sources – everyone knows that.
This is just a most strongly supported question. It’s probable, though not certain, that at least one person, somewhere in the world, has exceeded the RDA by eating lots of vitamin fortified cereal.
- We don’t know why people overeat cereal. Maybe they are aware of the RDA, and their mistake is simply about serving size.
- CORRECT. At least some vitamin fortified foods have 100% of the daily intake. Presumably other such foods at least have high quantities of vitamins. Since “many” people eat large servings, and since they likely get some vitamin A and D from the rest of their diet, it’s likely at least some people exceed the daily intake.
- The only mistaken belief in the stimulus is how big a serving is. But people may pour cereal because they want to eat enough food – they may not be considering vitamin intake.
- People may be deficient in certain vitamins even if they eat vitamin fortified foods. People might want to supplement those vitamins.
- Manufacturers might not realize how people eat! Also, we only know vitamins A and D are toxic in extremely high doses. It’s possible 2-3x the RDA is not a concern, and thus manufacturers don’t need to worry about overeating.
