How important are these really, if you are following a low carb diet?

One reason my doctor keeps trying to put me on a statin, is my dad. He also tries to put my mom on them.

My dad does have heart disease and kidney problems now. But, there is a lot of difference between us. He's smoked and drank for as long as I can remember. I don't smoke, though I drink wine when we eat out. I don't really think my risk is the same as his. I feel his risk/results are largely self inflicted. His mother lived to be 93. His dad died when I was little of emphysema.

My mom's mom is still alive (85). My mom smokes and she has smoked pretty much all my life anyway. (46). So, again, since I don't. I feel that changes my risks a lot. My grandmother doesn't smoke, but she does drink.

Is that the feeling most of you have?

Thanks,
