Organic Beef, Milk Shown To Be More Nutritious Than Conventional

April 5, 2016: 12:00 AM EST
British researchers and colleagues from around the world reviewed scientific studies on milk and meat, finding that organically grown products contained more beneficial nutrients, especially omega-3 fatty acids. The data showed that organic milk and meat have more desirable fat profiles, and could raise omega-3 fat intake by 50 percent without increasing calories and undesirable saturated fat. They also showed lower levels of myristic and palmitic acid in organic meat and a lower omega-3/omega-6 ratio in organic milk. There were also higher levels of fat soluble vitamins such as vitamin E and carotenoids, and 40 percent more conjugated linoleic acid (CLA) in organic milk. Organic cattle raising involves more outdoor grazing and low concentrate feeding than conventional raising.
