Look for Grass Fed Beef. When beef is grass fed, the beef is very healthy. It contains very little saturated fat, and is loaded with nutrients. Grass fed beef is rich in CLA, a powerful fatty acid that helps the body metabolize fat and lose weight that could be causing your back pain. A grass fed cow has from 2 to 4 times more omega 3 fatty acids in its meat. It is higher in the unsaturated fats while lower in saturated and great for our hearts!
