Jonathan Wolf和Dr. Sarah Berry讨论了食物中胆固醇的益处和坏处,以及对人体健康的影响。他们指出,长期以来,人们普遍认为膳食胆固醇会增加血液胆固醇水平,从而提高患心脏病的风险。然而,最新的研究表明,在正常的摄入量下,膳食胆固醇对血液胆固醇水平的影响很小。他们解释说,人体会通过复杂的机制来调节血液中的胆固醇平衡,包括肝脏产生胆固醇以及好胆固醇(HDL)和坏胆固醇(LDL)在体内的作用。他们还讨论了富含胆固醇的食物,例如鸡蛋、红肉、家禽和贝类等,以及这些食物对健康的影响。他们强调,虽然这些食物中含有胆固醇和饱和脂肪,但它们也富含蛋白质、维生素和矿物质等营养成分。因此,关键在于均衡饮食,而不是完全避免这些食物。他们还建议,人们应该关注整体饮食模式,而不是单一营养素,并推荐了地中海饮食等健康饮食方式。 Dr. Sarah Berry详细解释了胆固醇在人体中的作用,以及好胆固醇(HDL)和坏胆固醇(LDL)的区别。她指出,人体需要胆固醇来制造细胞和维生素D等物质,而血液中的胆固醇水平则受到肝脏产生胆固醇以及好胆固醇和坏胆固醇在体内的作用的影响。她还讨论了膳食胆固醇对血液胆固醇水平的影响,以及最新的研究结果表明,在正常的摄入量下,膳食胆固醇对血液胆固醇水平的影响很小。她还介绍了组合饮食法和地中海饮食等健康饮食方式,并指出这些饮食方式可以有效降低血液胆固醇水平,其效果与服用他汀类药物相似。她强调,人们应该关注整体饮食模式,而不是单一营养素,并建议人们戒烟,以改善HDL胆固醇水平,降低患心脏病的风险。

Cholesterol is a waxy substance made in the liver, essential for cell production and hormone synthesis. It's often misunderstood due to its reputation, but it plays a crucial role in the body.

Cholesterol in our food has a bad reputation. Many of us think of it as something to try to cut it out of our diet completely.  Yet new research could redeem eggs and other cholesterol-rich foods.
