Is Cholesterol from grass Fed meat healthier than that from grain fed or soy fed meat?
I had a short discussion with my father.He is doctor, a general practitioner. Actually he said if it would better that people eat more fruit and vegetables instead of meat. Cause meat has cholesterol and this clogs the arteries. His argument was that the federal social healthcare pay for it, so it has to be proven. Cause the federal healthcare wanna have the lowest cost so they suggest that diets which have the lowest risk of diseases.
So the main issue is: Is Cholesterol different healthy form different fed animals?
I would hazard a guess that the amount of oxidized cholesterol in the tissues of grain and soy fed would be higher because of the higher amounts of omega 6, but don't know of a study.
The bigger issue that would affect you is the mycotoxins from the food source that get stored in the animal fat, which have a greater effect on your VLDL and LDL than the cholesterol itself in the meat.
I have a video at http://www.bulletproofexec.com/bulletproof-video-get-stable-energy-perform-better-by-avoiding-these/ where I go through the effects (cancer and cardiovascular) of mycotoxins at low levels in the diet.
By the way, for my friend Angry Jeff who frequents Paleo Hacks and always has something constructive to say, this is another of the reasons the Bulletproof Diet is different from Paleo - my recommendations control for mycotoxins and other toxins, whereas Paleo diets often allow mold-contaminated foods, along with their xenoestrogens. Improperly stored or processed grass-fed meat is simply bad for you. I eat almost no xenoestrogens or other toxins, which is one reason I can eat 4500 calories/day for long periods without significant exercise while remaining muscular and lean. What you don't eat is as important as what you do eat.
Chemically cholesterol is cholesterol is cholesterol the source is irrelevant. What might be a factor is any toxins, etc ingested when said cholesterol is ingested. The majority of the cholesterol we use is manufactured in our own bodies.

Cholesterol in the diet does not have any effect on blood cholesterol. Your doctor is trying to sell you on "conventional wisdom" which is extremely flawed.
That said, there is a huge difference in the amount of Omega 3/Omega 6 fatty acids in conventionally raised meat vs. pastured, organic, grass-fed meat. Grass-fed is far lower in Omega 6 and generally has higher Omega 3 amounts. It makes a lot more sense to eat pastured meat, but not everyone can afford to. Wild-caught fish would be my go-to meat in that case.
