You are right to be sceptical, Maw, there is a great deal of controversy over statins and cholesterol in the medical profession.
15 years ago, when I was 60, a routine blood test showed my cholesterol level to be higher than the NICE guidelines (it was over 6), so my then GP decided I should be on a statin, and prescribed simvastatin, the cheapest one. Within a week, I had severe muscle pain, and gut discomfort, so decided to stop them. GP suggested a different statin, but I declined.
I’ve done a bit of research on cholesterol, which, naturally, gives much conflicting results, but you can read what Dr Aseem Malhotra has to say ( he is a highly esteemed cardiologist in the UK):

He believes that sugar (both refined and hidden in carbs) is the major culprit for cardiovascular damage (sugar is very inflammatory in the body), and that eating a healthy, low-carb diet is a much healthier option.
Like you, I am not on any medication, and have low-to-normal BP, and I hope to remain that way, as I prefer to avoid pharmaceuticals where possible.
I went low carb 6 years ago, mainly for my gut’s sake, but have no idea what my cholesterol level is now.
I also believe that statins should only be prescribed for those who have already had a cardiovascular event or are at risk of having one, as the benefits are so minimal otherwise.
