The Dietitian's Dilemma, by Michelle Hurn, in which an iconoclastic professional takes on the establishment with mixed results. One of the more interesting facts I learned while reading it is that LDL is a powerful promoter of a healthy immune system. "There are several studies that suggest higher levels of LDL actually protect us against infection. As we age, preventing infection is one component to ensuring longevity."
Further, "Let’s take a look at what the data says. A study involving 347 individuals, all older than 65 years of age, found that low total cholesterol was a significant predictor of death due to nonvascular causes. Those with high cholesterol had half the risk of dying within the referenced population. (12) Higher cholesterol levels were directly related to elderly people living longer. This is the opposite of what we are taught in our health care system."
