Do elevated cholesterol levels cause heart disease?

In an article published in the American Heart Journal last year, it showed that in an examination of 137,000 people admitted to the hospital with heart attack, 70% of them had normal blood cholesterol levels!

The long-running Framingham Heart Study showed that after the age of 50 (when 90% of all heart attacks occur), lower cholesterol levels are clearly associated with a shorter life expectancy.

Is eating saturated fat the problem? NO! 

One of the first studies to implicate animal fat in heart disease came in the early 1900s. See if you can spot the flaws in this one. In 1908, Russian scientist, M.A. Ignatovsky fed protein-rich animal foods to a group of rabbits. He soon discovered that the rabbits developed arterial plaques and cardiovascular disease.  Researchers discovered that the same thing happens when chickens, guinea pigs and goats eat a high-fat diet.

Later these studies were cited as evidence of a high-fat diet causing heart disease in humans. Hmm… let’s see. All of these animals are obligate herbivores. They evolved eating nothing but plants. They are clearly not designed to eat meat. When we feed them meat and fat it makes them sick. That makes perfect sense. What doesn’t make sense is why researchers extrapolated these results to omnivorous humans.
