Fedup2, I know you're a researching machine...contact this researcher, he is one of the top researcher dealing with actual field/lab studies dealing with grassfed beef fatty acid profiles (as an indication of what he's found,he feeds his family 100% forage raise meat and dairy products).

This is an interesting article on several levels...

See if you can find health research that segregates animal fats and vegetable oils. In the early 1900s hydrogenated vegetable oils(margarine and Crisco) were promoted as healthier than animal fats(butter, lard, beef tallow)...these are the same trans-fats that are being banned today!!!!! :shock:

"Sound science" isn't always so "sound" when big money is involved.
"Saturated fats have been shown to increase cholesterol levels in humans," she added]"
My point here is that I don't agree that animal fats are the problem. Our genes developed on a diet high in animal fats over thousands of years...why have animal fats become poison to our bodies in the last 100 years?????????????????????? Could it be MONEY??????????????????
Here is what sells me on grassfed...I started in 1998 by stopping deworming and using any pesticides; next eliminated any grain supplement for molasses supplements...then stopped them; cut back on minerals and now have stopped them; haven't vaccinated anything in three years now: feed is only forage in the pasture, hay and alfalfa pellets(mainly to put the herd in the catch pen to sort). My vet cost last year was for one semen test that was 95% live(actually close to 100%, but I believe my vet was afraid to put that). My herd is healthier than it has ever been...I simply don't have health problems.
Now, I have to conclude that eating the types of food that Nature intended for animals to consume(that match their genetic makeup) WOULD KEEP THEM HEALTHY????????????????????????? Wouldn't it work for humans too?????????????????
