Why did people who ate lots of beta-carotene in their food avoid deadly cancer and heart disease when people taking beta-carotene supplements experienced no changes to their health?

The correct answer must fail to explain why people in the two studies experienced such different health outcomes. Every wrong answer, meanwhile, will state a flaw in the studies’ designs or explain why people who eat foods rich in beta-carotene are less likely to die from cancer and heart disease than those who take a supplement.

This would explain the discrepancy. People who eat foods rich in beta-carotene process more of it than those who only take supplements.

This would explain why people in the first study showed benefits while people in the second study did not. Those in the second study did not consume high levels of beta-carotene over a long enough period to achieve health benefits.

This would explain the discrepancy. People who eat foods rich in beta-carotene eat food also rich in other nutrients, and those nutrients cause the lower risk of deadly cancer and heart disease.

This does not explain the discrepancy. The author states that people who took the supplements experienced no health benefits, regardless of the placebo group.

This would explain the discrepancy. People in the first study were less likely to die of cancer and heart disease because they were less likely to smoke cigarettes.
