That being said, I think it should be pointed out that you're still probably better off focusing on grass-fed beef and wild-caught fish than chicken or pork, and the general categories of animals, vegetables, squashes and tubers over nuts and seeds, and whole foods over processed manufactured products.
Not sure exactly what that means for the OP's LDL question, however. Is it LDL-C that's a problem, LDL-P, ox-LDL, TG:HDL, TC:HDL, or none of the above that we should be worried about? The concensus is that there's no concensus. So we're back to the same prescription. Eat a diet high in fats from healthy animals and low in processed seed oils.
The really are out to get us.Soybean oil alone is now so ubiquitous in fast foods and processed foods that an astounding 20 percent of the calories in the American diet are estimated to come from this single source.

Grassfed beef and wild caught fish are better because they are more nutrient-dense per calorie and don't contain the antibiotics that CAFO-raised animals do. Farmed salmon is a nasty gray color (color is added later) while wild caught salmon is a nice orange/pink. I think that says a lot about the health of the animal you are eating. Eating sick animals sick people.
I don't think there is anything wrong with eating chicken. At all. Do I think beef and lamb are healthier? Yea, but let's not let perfect be the enemy of good. Chicken is still healthy.
I think vegetables, squashes and tubers are healthier than nuts and seeds because they contain less anti-nutrients and are much more nutritious per calorie. Whole foods over processed is a no-brainer, except in rare exceptions (white rice vs brown rice, nixtamalized corn vs untreated corn, soaked nuts/legumes vs raw...of course it's up to you to decide if these are all whole foods).
