High cholesterol and heart disease
Australia's ABC program Catalyst has been showing a really interesting investigation of the the role high cholesterol in heart disease.
The first program showed how poor the evidence actually is that high cholesterol actually causes heart disease.
The second program showed that there's a been a massive scam and by the pharmaceutical industries and other medical powers to prescribe drugs to lower cholesterol.
These drugs make billions of dollars every year, but are largely ineffective with terrible side effects.
