For high ldl (168), thyroid replacement therapy(60 mcg synthyroid), doctors say reduce dairy products . so how should we get calcium? is slim milk ok?

High LDL cholesterol: 168 is pretty high for LDL ("bad") cholesterol, but it is not the end of the story. Eat 5 servings of fruits & vegetables a day. Eat grains and oatmeal. Metamucil for your bowels also lowers cholesterol by 10%. Exercise& stress reduction helps. And medications like statins, zetia, and Niacin help. I doubt the efficacy of synthroid, (thyroxine) which has potential significant adverse effects. Skim milk ok.

Agree with Dr. K: Reduce you intake of saturated fats, lose weight, exercise at least 30 minute/day, and if that does not bring LDL down (depending on other risk factor to less than 130 or lower) take statins as advised by your doctor. Skim milk is okay.
