@Jillytee , yet again clever peeps have beaten me to the opinion I would offer... Keep reading on the cholesterol threads, the NHS advice is outdated, and evidence suggests just plain wrong. I could never advise you go ignore your GP, but I've learnt that our (the general public's) understanding of "cholesterol" is badly skewed.
Cholesterol itself is wonderful stuff. It helps maintain the outer coating of the bodies cells; it makes up bile acids that work to digest food in the gut; and it allows the body to make Vitamin D and hormones, like oestrogen and testosterone.
As I understand it our bodies self regulates the amount of cholesterol we need, if we take more in our diet, the liver produces less.
The trick of course is to get the balance right between Low Density Lipoproteins (LDL small dense particles which can lead to fatty plaque deposits in our blood vessels) and High Density Lipoproteins (HDL which mop up any excess cholesterol and transport it to the liver to be excreted). LDL and HDL are frequently referred to as cholesterol, but this is incorrect, they are proteins that carry cholesterol in the blood.
Recent research has concluded that current evidence does not support low consumption of saturated fats in the prevention of heart disease and stroke. Very simply, small, dense LDL, present itself in our diet in the form of transfats and excessive carbohydrates (chips, burgers, pies, cakes), NOT animal fats or eggs.
My opinion is that this is another case where the medical profession is running behind the research, much like it's dietary advice ie LCHF?
