Question for Delphi Doc

[SweatHawg]

Just curious.....any thoughts as to how much diet or genetics plays a role in cholesterol?....
I know we are all individuals but--when I saw my MD a few months back for a routine checkup, my lab work came back with my cholesterol at 141...great I thought. The year before it was 162...I asked my Doc how could my cholesterol have dropped that much when I eat meat every meal & I am eating more red meat now than in the past. My wife is 5'7", a few pounds under weight actually with one of the smallest waist's you will ever see. She eats a lot of fresh fruit,veg's, salad & drinks water all day. Her cholesterol was about 210-not real high but as active as she is & with her healthy diet, I thought hers would be better!
When I questioned my doc about mine dropping & hers staying over 200 his answer was , "I think a lot of that is just genetic, doesn't matter what you eat." I thought that as I put him on the spot that, was the first thing he could think of-just a generic answer. What are your thoughts--- \Thanks in advance/

I'm not an internist and I don't treat hypercholesterolemia so I'm not an "expert" on this. Genetics has a lot to do with cholesteral and triglyceride levels. Some people have TG levels over 1000 no matter what they do. I can eat 4-6 eggs a day (I used to do that) and still run a cholesterol well under 100. Exercise will improve your numbers in general and also improve your HDL/LDL ratio- higher HDL and lower LDL is better.

HDL = high-density lipoprotein = "Healthy"- goes up with exercise
LDL = low-density lipoprotein = "Lazy" - goes up with inactivity
Cholesterol- goal is under 100
Triglycerides- goal is under 200

There's supposedly a village of people somewhere in the world (Italy?) that has almost no coronary artery disease. Their TG levels are sky-high but they lack a carrier protein, or enzyme, or their HDL levels are very high, or something to that effect. They're an extreme example to show that the lab numbers alone are not everything.

it's partially genetics, partially what you eat. you can have a total cholesterol count well over 200 and still be in the best of health, provided your HDL/LDL ratios are good.

incidentally, in my opinion, what you eat counts, but not in the way we've been taught to think it does, since Dean Ornish....i believe a diet high in refined carbs and low in protein and fat is more responsible for a messed up HDL/LDL ratio then the a diet high in dietary cholesterol.

Got my numbers backwards. As Tryska alluded to, you want a cholesterol <200. Triglycerides should be somewhere under 150, depending on the lab. Under 100 is cool. See, I told you I'm not well versed on cholesterol stuff... Can't operate on it, isn't important. j/k :D
