Br J Clin Pharmacol 2001;52:439-46.) - Honolulu Heart Program 2001: " Our data accords with previous findings of increased mortality in elderly people with low serum cholesterol, and show that long-term persistence of low cholesterol concentration actually increases risk of death...the earlier patients start to lower cholesterol concentrations, the greater the risk of death. " (Lancet. 2001 Aug 4;358(9279):351-5.) - ALLHAT 2002: in the largest North American cholesterol-lowering trial ever and the largest trial in the world using Lipitor, mortality of the treatment group and controls after 3 or 6 years was identical. (The ALLHAT Officers and Coordinators for the ALLHAT Collaborative Research Group. JAMA 2002;288:2998-3007.) - Heart Protection Study 2002: received widespread press coverage indicating " massive benefits " from cholesterol-lowering; those who took simvastatin (Zocor) had an 87.1% survival rate after five years, compared to an 85.4% survival rate for the controls, and these results were independent of the amount of cholesterol lowering. (Heart Protection Study Collaborative Group. Lancet 2002;360:7-22.) - J-LIT 2002: a 6-year study of 47,294 patients treated with simvastatin; results showed higher mortality at the lowest serum cholesterol (both total and LDL), and the lowest mortality at the highest serum cholesterol (both total and LDL). The higher mortality at low cholesterol levels was due to increased cancer. (Matsuzaki M and others. Circ J. 2002 Dec;66(12):1087-95.) - CARE 1996: risk of death from CHD for those with pre-existing CHD went from 5.7% to 4.6% (Sacks FM, et al. New England Journal of Medicine 1996;335:1001-1009.) - WOSCOPS 1995: risk of death from CHD for those with pre-existing CHD went from 2.6% to 2.2% (Shepherd J, et al. New England Journal of Medicine 1995;333:1301-1307.) - " The statins correct plasma lipid levels optimally, yet the real magnitude of their benefits is marginal and certainly not better than attained with agents that do not affect plasma lipid levels. It is suggested that some of our recommendations and actions relating to plasma cholesterol levels and to atherosclerosis are based on concepts that are fundamentally flawed and need to be revised. " (Krut LH Am J Cardiol 1998.) - " The beneficial effects of statins on clinical events may involve nonlipid mechanisms that modify endothelial function, inflammatory responses, plaque stability and thrombulus formation...These nonlipid properties of statins may help to explain the early and significant cardiovascular event reduction reported in several clinical trials of statin therapy. " (Rosenson RS JAMA 1998) - In people older than 85 years, high total cholesterol concentrations are associated with longevity owing to lower mortality from cancer and infection. The effects of cholesterol- lowering therapy have yet to be assessed. (Lancet. 1997 Oct 18;350(9085):1119-23.) - Our findings do not support the hypothesis that hypercholesterolemia or low HDL-C are important risk factors for all-cause mortality, coronary heart disease mortality, or hospitalization for myocardial infarction or unstable angina in this cohort of persons older than 70 years. (JAMA. 1994 Nov 2;272(17):1335-40.) ** ACCORDING TO THE FIGURES FROM THE WOSCOPS TRIAL, If you treated someone for 30 years you can expect to provide them with 30/700 added years of life. This is 15.64 days... In short, if a fifty year old man asked you how much longer he could expect to live if he took a statin for thiry years you can inform him " just over two weeks — max. " (Dr. Malcom Kendrick, " The Great Cholesterol Con " ) There is more but perhaps I should stop here. The conclusions are as follows: 1) Statins MAY reduce CHD mortality in primary prevention populations (people who've never had heart disease), but they do not reduce total mortality in this population 2) Statins do not reduce CHD rates or total mortality in women 3) Statins do reduce CHD mortality in secondary prevention populations (people who have or had heart disease), but do not reduce total mortality in this population 4) Statins do not reduce CHD or total mortality. In fact, elderly people with low cholesterol die twice as often as elderly people with high cholesterol. 5) CONCLUSION: statins do not, therefore, reduce overall mortality in >95% of the human population If you have data that indicate otherwise, I'd love to see it. The problem this raises for me is that if oxidized LDL was a primary cause of CHD and CHD mortality, and statins reduce levels of ox-LDL across the board (which is not in dispute by anyone, it seems), then why aren't statins reducing CHD rates in women and the eldery?

I have looked into this in great detail and have a lot of studies handy since I'm preparing for a presentation. Here is a good summary of the studies on elderly & statins: http://junkfoodscience.blogspot.com/2008/01/reading-evidence-closely-statins- for.html See here for info on women and elderly: - Abramson and contend that statins did not reduce coronary heart disease events in the almost 11 000 women in pooled trials, nor in men and women older than 69 (n=3239).

The deeper I get into the data and analysis of the data, the more clear it becomes that we just can't be sure of the exact mechanisms of CHD. Nor can we be sure exactly how statins work. However, most people simply aren't interested in the finer points of this debate. What most people want to know is " what can I do to promote health and well-being and improve my quality of life as I age " ? " What should I eat? " " Should I take statins? " And ultimately, as a future health-care professional, those are the questions I'm most interested in as well. From my reading of the data, we can answer those questions with some certainty. That's why in my mind the total mortality data is so much more important than the rates of CHD, and even CHD-related deaths. Who cares if a statin reduces CHD events when it raises mortality from cancer and other diseases at the same time? Personally, I'd much rather die from a massive MI than a long, painful cancer. What I feel very good about telling the people I work with is this: 1) There is absolutely no evidence that eating cholesterol and saturated fat in the diet raises cholesterol levels in the blood. 2) A diet high in saturated fats and cholesterol is far more healthy for your heart (and the rest of your body) than a diet high in PUFAs and refined carbohydrates (the so-called " heart healthy " approach). 3) The only aspect of your cholesterol levels you should (probably) be aware of is the L(p)a (as an indicator of the level of oxidization of LDL) and the ratio of ApoB100 to LDL (as an indicator of the density/size of LDL particles). The way to reduce ox-LDL and minimize the small, dense LDL particles is to avoid PUFAs and trans fats in the diet and eat plenty of egg yolks (see #3 above). 4) Statins do not reduce total mortality in >95% of the population. They have serious and significant side effects and risks, many of which are underreported. They have been shown to cause cancer in every animal study done to date. In the highest risk population (middle-aged men who already have CHD), a 50-year old man would have to take a statin for 30 years to extend his lifespan for 2-weeks. Statins do not reduce total mortality in primary prevention populations or women, and they actually increase total mortality in the elderly (high cholesterol is protective in this population). On a practical level, for most people, I think the four points above are what it really boils down to. The details we are hashing through are only relevant (in my mind) to the extent that they change the recommendations above in some way. Otherwise, they are mostly academic. (No judgment there! I enjoy learning about this stuff and talking about it. But I'm speaking of what I think is relevant to our daily lives.) K. Quote Link to comment Share on other sites More sharing options...

I would like to see the data from which you draw this conclusion. Where can I find those metabolic ward studies? Because I have seen a lot of studies that indicate the opposite (regarding the effect of saturated fat consumption on serum cholesterol). - " In Framingham, Massachusetts, the more saturated fat one ate, the more cholesterol one ate, the more calories one ate, the lower people's serum cholesterol... we found that the people who ate the most cholesterol, ate the most saturated fat, ate the most calories weighed the least and were the most physically active. " (1992) - In a study of 10,000 Israeli civil servants, intake of animal fat ranged from ten grams up to two hundred grams daily. Yet there was absolutely no relationship between intake of dietary fat and cholesterol levels. (Kahn HA, and others. Israel Journal of the Medical Sciences. 1969;5:1117 1127.) - A survey of South Carolina adults found no correlation of blood cholesterol levels with " bad " dietary habits, such as use of red meat, animal fats, fried foods, butter, eggs, whole milk, bacon, sausage and cheese (Lackland DT, et al. J Nutr, Nov 1990. 120:11S:1433- 1436) - The Masai tribe in Africa subsist largely on whole milk, blood and beef. Yet their cholesterol is among the lowest ever measured in the world, and about 50% of the average Americans' (Lapiccirella V., and others. Bulletin of the World Health Organization 1962;27: 681-697.) - There is not a single long-term study showing that a high-cholesterol, or high saturated fat diet, has any impact on blood cholesterol levels in a normal, healthy population (Farr, M.D., " Why the Cholesterol-Heart Disease is Wrong " , http://www.thincs.org/) If the above statement by Dr. Farr is incorrect, I would like to see that study if you have the reference.

Since you advocate eating saturated fat, and since you believe ox- LDL is a contributor to CHD whereas " normal " (light, fluffy) LDL is not, I'm assuming that you believe saturated fat increases the " normal " LDL and not ox-LDL. (That's a lot of assumptions about what you think, so please correct me if I'm wrong!) In the study you reference, did total, HDL, LDL or all three go up after eating SFA? How much? Of what relevance do you believe this finding is, in light of the fact that you support eating SFAs over PUFAs? K. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted February 8, 2008 Report Share Posted February 8, 2008 I'm just one person BUT last June, I began eating a whole foods, no sugar no grain diet. The only fats I use are butter, coconut oil and once in a while, a small amount of olive oil. I eat plenty of meat, mostly chicken. My total Cholesterol went from around 300 to 150 in that amount of time. HDL increased from 30 to 50 and LDL came down a little, but still high. So, for me personally, I certainly don't fit what was written and from my research, something sounds very wrong with that conclusion. " It has long been established that substituting SFA for PUFA raises levels of cholesterol in the blood in very tightly controlled metabolic ward studies " .

It sounds like you dramatically reduced your carbohydrate intake, which would lower your cholesterol. You were substituting SFA for both PUFAs and carbs, so although the SFAs may have had a very slight cholesterol raising effect vs. the PUFAs, the huge reduction in carbs had a much more significant effect in lowering your cholesterol. And of course, many like Dr. Ravnskov and Colpo would simply say that SFA consumption and serum cholesterol aren't correlated. K. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted February 9, 2008 Report Share Posted February 9, 2008 I just want to say thanks for the explanations to both Chris's. That makes sense. I'm fairly new to this way of life and although I knew the correlation between HFCS and triglycerides, I didn't realize all carbs affected it to. Learn something every day. Actually, I learn more somethings every day here and other places than I can keep up with:) I just want to say how much I appreciate ya'll (and everyone else) being so willing to share their knowledge and answer questions.
