Nutrition scientist Dr. Lisa Park challenges the common belief that eating eggs raises cholesterol to dangerous levels. She argues that dietary cholesterol has less impact on blood cholesterol than previously thought, and that eggs provide valuable nutrients.
Which research finding would most directly support Park's revised view of eggs?
Participants who ate two eggs daily for 12 weeks showed no significant increase in harmful LDL cholesterol compared to participants who avoided eggs
Eggs are a good source of protein and vitamins
Many breakfast foods contain eggs
Cholesterol medications are effective at lowering blood cholesterol
Correct Answer: A
Choice A is the best answer. Controlled study shows eating eggs doesn't raise LDL—directly disproving the old belief.
- Context clues: Park challenges the belief that eggs raise cholesterol.
- Evidence evaluation: No LDL increase despite daily eggs proves dietary cholesterol impact is low.
- Verify: Comparison to egg-avoiding group isolates the egg variable.
💡 Strategy: Challenging common beliefs requires evidence that contradicts the belief.
Choice B is incorrect because nutritional content doesn't address the cholesterol question. Choice C is incorrect because egg prevalence doesn't prove health effects. Choice D is incorrect because medication effectiveness doesn't relate to dietary impact.
