My numbers didn't change at all before and after NSD: low trigs, good HDL, elevated LDL. I eat far more red meat now, but my numbers have stayed pretty constant. All the women in my family have above normal LDL, including my sister when she was in her early 20's, so I've never worried about it.

As I get older my doc will probably care more, but at that point I will insist on a particle size test. I am wary of the polyunsaturated fat advice since most food sources didn't exist 100 years ago (my philosophy is to not eat anything my grandmother wouldn't recognize as food). I take vitamin k2 to protect against the accumulation of calcium in my arteries.
