Cholesterol Facts

Question: what are some facts about cholesterol? what are some facts about cholesterol?

Answer: Cholesterol is an essential structural component of mammalian cell membranes, where it is required to establish proper membrane permeability and fluidity. In addition, cholesterol is an important component for the manufacture of bile acids, steroid hormones, and fat-soluble vitamins including Vitamin A, Vitamin D, Vitamin E, and Vitamin K. Plaque build up in the arteries are more attributable to carb consumption than dietary fats, which seems to be the conclusion of the following study. Carb consumption raises triglycerides & VLDL (bad cholesterol). Fats raise the HDL (good cholesterol). High triglyceride levels & low HDL levels are an indicator of plaque, glycation - the precursors to a heart attack and heart disease. study from the Oxford group examining the postprandial (after-eating) effects of a low-fat vs. low-carbohydrate diet. (Roberts R et al, 2008) Postprandial lipoproteins, you'd think, would be plentiful after ingesting a large quantity of fat, since fat must be absorbed via chylomicrons into the bloodstream. But it's carbohydrates that figure most prominently in determining the pattern and magnitude of postprandial triglycerides and lipoproteins. Much of this effect develops by way of de novo lipogenesis, the generation of new lipoproteins like VLDL after carbohydrate ingestion. http://heartscanblog.blogspot.com/2009/11/after-eating-effects-carbohydrates-vs.html The link between saturated fats and heart health was based on faulty science & has been disproven. Dietary fat, whether saturated or not, is not a cause of obesity, heart disease, or any other chronic disease of civilization. Through their direct effects on insulin and blood sugar, refined carbohydrates, starches and sugars are the dietary cause of coronary heart disease and diabetes. http://www.drbriffa.com/blog/2010/01/15/two-major-studies-conclude-that-saturated-fat-does-not-cause-heart-disease/ FINALLY they admit - no difference in the risk of heart disease even with highest intake of saturated fat & eggs are a superfood & have no effect on cholesterol http://blogs.webmd.com/heart-disease/2010/03/low-fat-diet-trojan-horse-of-heart.html
