Dr. Naomi D.L. Fisher, Associate Professor, Harvard Medical School, has highlighted the importance of post-prandial cholesterol as the preferred state for measurement and has stated, “Perhaps more important, large-scale analyses have shown that non-fasting lipids don’t weaken the connection between cholesterol levels and harmful events like heart attack and stroke. In fact, post-meal measures are thought to strengthen the ability of lipid levels to predict cardiovascular risk. This observation may stem from the fact that most people eat several meals plus snacks during the day. That means we spend most of our time in a “fed” state, not a fasting state. So lipid levels after eating may best reflect our normal physiology.” In other words, measuring cholesterol levels of subjects in a post-prandial state are not only more relevant, but more accurate of predicting cardiovascular risk.
The following video further explains post-prandial measurement vs. fasting cholesterol measurement as it relates to cardio-vascular risk and how the Egg Nutrition Center (an arm of the marketing entity the American Egg Board) design misleading studies.
哈佛医学院副教授Naomi D.L.Fisher博士强调餐后胆固醇是更好的测量状态，他表示：“可能更重要的是，大数据已经展示出非空腹血脂并不使胆固醇值和诸如心脏病和中风之间的联系减弱。事实上，餐后测量被认为加强了血脂水平预测心血管风险的能力。这项观察可能源于大多数人一天中加上零食会吃好几顿餐的事实。那意味着我们大多数时间都是处于“进食”状态，而不是禁食状态。所以餐后血脂可能最能反映出我们平时的生理机能。换句话说，测量餐后胆固醇值不仅更有意义，而且对于预估心血管风险更精准。
以下的视频进一步解释了餐后和禁食状态下胆固醇值的测量，因为它与心血管风险以及鸡蛋营养中心（美国鸡蛋委员会的一个营销分支）如何设计误导研究有关。
