How bad is bad....and the other things is what your good cholesterol is as in relationship to the bad stuff.
I was at 5.1 mmol/L and I could see the doctor getting on his sales pitch. Nipped that one, (i) I haven't dieted before the test, which the Americans recommend to get to the real baseline and not measure the steak last night and (ii) it was your mate who recommended the all-protein and veg diet and my cholesterol is surely bound to go up (from 4.8 mmol/L). My HDL (the good stuff) was at 88 mmol/L - so nothing wrong there. For the latter, apples, red wine and pistachios are good, so is weight loss and say 60 mins of exercise a week.
