Statement relation comments

AI Verified Relevant: in context, Katz’s quote is presented as part of the article’s explanation that dietary cholesterol from egg yolks is not the main driver of blood cholesterol, while the piece says evidence does not support a strong link between dietary cholesterol and heart disease. That makes a determinable stance on the statement substantially more likely.

AI Verified Against: Katz says blood cholesterol is mostly made in the liver, "not delivered directly from our diet," and the article uses that point to argue egg yolks were not the main problem; it says saturated fat, not the cholesterol in eggs, is the bigger cardiovascular risk driver.
