Effect of dietary lipids on beta-carotene absorption into micelles [PDF]

, 1991
As beta-carotene is transported via micelles across the intestinal lumen for absorption, the factors that regulate uptake into micelles could also regulate at least in part beta-carotene absorption in humans. Thus, we have studied the effect of different
