Much of the "scientific" research in favor of statins is flawed and fraudulent. 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 article on how statins, and a cholesterol-lowering popular diet pill advertised by Dr. Oz, promote diabetes at How Statins & Garcinia Cambogia Side Effects Raise The Diabetes Risk

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 flawed and fraudulent "scientific" studies conducted by people with vested interests.

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. Statins have almost no real benefit in the very vast majority of users. They do more harm than good. It's a "scientific" scam.
