The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

The study investigated the association between total cholesterol levels and all-cause mortality in 490 elderly individuals aged 75 years or over, with a six-year follow-up.

The study found:
(a) Those with cholesterol levels below 5 mmol/l (193 mg/dl) had a 52% increase in death rates compared to those with cholesterol above 6 mmol/l (232 mg/dl).
(b) Death rates increased by 18% for every 1 mmol/l (38 mg/dl) decrease in cholesterol levels.

To conclude: People with low cholesterol have a lower survival rate than people with an elevated cholesterol level, irrespective of disease or health status.
