It might prevent a heart attack caused by plaque buildup in the arteries. That said, there’s little doubt it comes at a cost to the muscles.
My sister was prescribed statins for cholesterol and was on it for 3 years. She was diagnosed with Dementia this year...would that they would find proof of the connection!
There is no evidence that the plaque built up in the arteries is prevented or helped by statins, the cause, or affected by diet. They do not know why cholesterol would suddenly stick to artery walls at all. There is evidence that such disease is related to oral spirochetes, a bacteria, that gets into the body via bleeding gums. . . and which is related to all plaque related diseases.
