As you will learn from reading that article, there are many problems with traditionally raised beef. Cattle were not designed to eat grains; they were designed to eat grass. A whole series of nasty side effects occur when you feed grains to cattle.
One such effect is that you shut off their production of many beneficial fats. CLA is a classic one. As the above study shows, CLA is useful for a variety of problems, and control of diabetes is an important one.
There are two primary ways to receive CLA. One is through milk products and the other is meat. However, it will only be in those foods if the animal was not fed any grains.
Please don’t let some of these highly deceptive marketers fool you. Many stores will advertise beef as grass-fed, because virtually ALL cattle are grass-fed initially. But what matters is what they are fed in the months prior to their slaughter, not what they are fed initially, and most cattle are fed grains during this time.
When commercial cattle are fed grain, and this includes nearly all of them, it causes them to stop virtually all CLA production. So, what you want is grain-free beef and cow’s milk
