Jerry,
Thanks for the post.
The decision to go on a statin drug, like lipitor, is not as simple a decision as it might seem. I generally use a rule of thumb -- prescribing the drug when a person has high cholesterol plus one other risk factor. You did not name a second risk factor, but that does not mean that one does not exist.
Several web sites have risk calculators that can help in the decision. Check out http://www.nhlbi.nih.gov/about/ncep/ as a starter.
Good luck.
Your daughter is in good shape with 55.
She seems to be normal weight and fit, but perhaps can get TC below 200 by taking as much meat and dairy out of her diet as possible.
If not, a low dose of a statin like Lipitor would definitely do the job. She might also try an LDL absorbtion blocker like Zetia. If there are no apparent side effects, either would probably be beneficial.
