Research is always in motion… but there is anecdotal evidence in the bodybuilding world that scares the shit out of me–all the pros who ate eggs yolks daily without exception developed heart problems by the time they hit 50. Essentially without exception. Those who ate just the egg white did not.
Maybe its ok to spend half the year with high total chol, whereas we used to think it was highly problematic, but it might also be true that to spend a majority of the time that way is still deadly.[/quote]
There is a reasonable explanation as to why the egg yolk-eating body builders may have got heart issues compared to the group avoiding yolks, although your observation, as finley had said, is merely anecdotal at this point rather than solid data.
Cholesterol usually becomes only an issue if it is being oxidized where it then can add to the athersclerotic process. Egg yolks are high in fats and cholesterol and eating lots of them, in combination with heavy exercise, and eating a low antioxidant diet can potentially promote the oxidation of this dietary cholesterol and lipids. However, if you eat more cholesterol the body automatically will produce less on its own. You’d have to eat in the neighborhood of 20 or 30 egg yolks a day to probably activate detrimental effects.
finley is right that the matter with cholesterol has been going on for decades. Your notion that “Research is always in motion” seems to imply that it’s a honest rather straight-forward process. If you look at how organized medicine and medical research works you’d know that the majority of medical research is not in a constant search for truth but for whatever dogma and ideology makes them a ton of money WITHIN corporate business which is mostly a disease-management, thus lucrative, model. This history of cholesterol of the last 60 years clearly shows that.
One of the dogmas that was favorable to generating huge profits for the medical business was that cholesterol causes heart disease, out of which the business cartel created cholesterol-lowering drugs such as statins.
The most reliable evidence has long tied statin use with memory problems, muscle disorders, liver damage, cataracts, nerve damage, pancreatitis, erectile dysfunction, brain dysfunction, diabetes, and with an increased risk of cancer and higher mortality (statins only somewhat reduce the risk of non-fatal heart attacks).
The physiological mechanisms of how statins do serious damage are also well understood, such as by their impairment of oxidative cell metabolism, the increase in inflammation and cell destruction, the lowering of cholesterol and steroid hormone production, the promotion of pancreatic injury, etc. - rather thoroughly explained in this scholarly well referenced article on how statins, and a cholesterol-lowering popular diet pill advertised by Dr. Oz, promote diabetes at http://www.supplements-and-health.com/garcinia-cambogia-side-effects.html - look at Figure 7 to see how irrational it is to block the production of cholesterol!
Yet despite of the existence of that scientific knowledge, the medical business and the public health authorities keep ignoring it and continue to recommend statins to diabetics and make claims that they have a low risk profile despite that they are also significantly linked to cancer and higher mortality (just look at the propaganda put out by the Mayo clinic on statin drugs: “the risk of life-threatening side effects from statins is very low”).
And because of such medical propaganda, few people are aware that the medical claims of benefits of statins are mostly based on junk studies conducted by people with vested interests. And, logically, it’s mostly the corporate medical business and other people with similar vested interests tied to it (eg, mouthpieces, hacks) who promote the alleged value of these highly lucrative products.
Also, older people with HIGH cholesterol live longer than those with low cholesterol levels (see above mentioned article for numerous scientific study references confirming this).
Because the cholesterol-heart disease theory, or rather medical dogma, is wrong, the use of statins is also wrong by logical extension.
So the real truth is that statins have almost no real benefit in the very vast majority of users. They do more harm than good (read Uffe Ravnskov’s “The Cholesterol Myths” and Malcolm Kendrick’s “The Great Cholesterol Con”). It’s one of many “scientific” scams of the mainstream medical business.
