Well, this isn't what you are going to want to hear, but my opinion is that it worrying about that ratio is just for people eating a lot of fat.
To further add to the confusion, raw LDL and HDL numbers are really only part of the issue. I have posted before research that shows even the large partcile LDLs can inflict damage to the arteries. But probably the biggest culprit are small (and oxidized) VLDL. You want to focus on those and make sure you are not a "pattern B" person. Read some about that.
It is also very critical to focus on inflammation. Certain antioxidants will protect against oxidation of the LDL and eating low glycemic carbs and exercise will keep you out of the "pattern B" zone.
Now I'm mentioning all of that because LDL/HDL ratios are kind of "old techology" that are only so useful. We now know MUCH more about cardiovascular risk factors. It is a pretty involved subject but the real keys are this:
--Low glycemic foods.
--A good quantity of fruits, vegetables, bean, legumes (and non-wheat whole grains)
--Elimination of all high glycemic foods including wheat, sugars, refined carbs.
--Adequate sleep (to control insulin/cortisol levels)
--Get your abs back, i.e. get rid of visceral fat
--Reduce stress through PMR/secular meditation
These are the keys that are really going to pay HUGE dividends and, of course, you know that I think the best way to do all of the above goals is through a low glycemic, Low Fat Diet.
