In 14 healthy volunteers, the addition of 12 g cholestyramine to a vitamin A-containing test meal reduced the expected rise in serum vitamin A by 59.5% (p<0.001). By contrast, lignin had no significant effect in 12 subjects. This study confirms the importance of bile acids in vitamin A absorption and the ineffectiveness of lignin as a sequestrator of conjugated bile acids.
在14名健康志愿者中,在含维生素A的试验餐中添加12克消胆胺使血清维生素A的预期升高降低了59.5%(p<0.001)。相比之下,木质素在12名受试者中没有显著影响。这项研究证实了胆汁酸在维生素A吸收中的重要性以及木质素作为结合胆汁酸螯合剂的无效性。
