Your hdl is only important as part of the total cholesterol.
So when you have more high than low it’s a good thing.
Low density cholesterol is stickier and can accumulate. While higher density will pass through.
But even high density will stick if there already is a blockage.
That’s why I think low total cholesterol, low triglycerides and low ldl is key. If you have all that then your Hdl will be higher by default.
