Contrary to what you may have heard, butter can be a very healthy food. Organic, whole-milk butter from grass-fed cows is loaded with vitamins A, D, E, and K, trace minerals, and the potent cancer fighter conjugated linoleic acid (CLA). Grass-fed butter also has a healthy ratio of omega-6 to omega-3 fatty acids.
However, all these benefits are compromised when the butter is made from milk that comes from grain-fed cows. Besides lacking nutrients, the fat composition of this butter is distorted. That turns it into a health risk instead of a health enhancer.
If you enjoy butter, go ahead and eat it. But be sure it’s the organic, grass-fed kind.
