The ideal level for total cholesterol is <5 mm oles. However the cholesterol/HDL ratio is also important as a guide to risk. It is said as a rule of thumb that each 1% fall in cholesterol produces a 2% reduction in heart disease risk.
If your cholesterol is that high you have very acidic blood and you need to increase your water and salt intake. Acidic blood happens when you're dehydrated and your body borrows the water it needs from the blood. This causes the blood to thicken and become acidic.
This acidic blood with its toxins wears away at the interior artery walls, causing minute tears and abrasions. To keep any of it from peeling off and causing an embolism in the brain, lungs or kidney, the body will produce cholesterol to act as a patch to protect the damaged areas until repairs can be made.
To lower your cholesterol, you need to increase your water intake so that the body will stop borrowing from the blood. This will allow the blood to thin naturally and will also allow the body to make the necessary repairs. You'll then start dissolving the excess cholesterol.
That is massively big! You should definitely think about a lowering cholesterol diet! The internet is full of information from what you should be eating to what you should wear
