summary - Two randomized controlled crossover studies in healthy men and women testing acute cholesterol absorption and the plasma total-cholesterol response to whole-egg meals. Dietary cholesterol from whole eggs was poorly absorbed and did not acutely raise plasma total cholesterol concentration.
relevance_note - Supplies an absorption/bioavailability mechanism for why intact-egg cholesterol under-delivers relative to purified-cholesterol feeding studies (e.g. Keys) - a mechanistic counterpoint within the same slice, not just another outcome data point.
