Grass-Fed Vs. Grain-Fed. Why Grass-Fed Beef Is Better Than Grain-Fed Beef

Cows, sheep and buffalo are all designed to eat grass. When these animals’ diets are primarily made up of grains, they have a higher chance of becoming sick and the quality of the fats and protein in their meat declines.

It’s safe to say that grass-fed meat such as beef gives you more bang for your buck on all fronts, with its significantly higher levels of omega-3s, antioxidants, minerals, and other important nutrients. Grass-fed beef is better than grain-fed beef. Here’s why in greater detail:

Fewer calories and less fat

  • Grass-fed beef is naturally leaner than grain-fed beef, causing it to be slightly lower in total calories and fat than a grain-fed product.
  • For example, a 6-ounce steak from a grass-finished steer has almost 100 fewer calories than a 6-ounce steak from a grain-fed steer.

Better omega-6 to omega-3 ratio

  • Grass-fed beef has the recommended ratio of omega-6 to omega-3 fats. Depending on the breed of cow, grass-fed beef contains between 2 and 5 times more omega-3 fatty acids than grain-fed beef, and the average ratio of omega-6s to omega-3s in grass-fed beef is 1.53:1. In grain-fed beef, this ratio jumps all the way up to 7.65:1. Too much omega-6 fatty acids in one’s diet is linked to disease.
  • Sixty percent of the fat content of grass is a type of omega-3 fatty acid called alpha-linolenic or LNA. When cattle are taken off grass and shipped to a feedlot to be fattened on grain, they lose their valuable store of LNA as well as two other types of omega-3 fatty acids, EPA and DHA. Each day that an animal spends in the feedlot, its supply of omega-3s is diminished.

Superior source of conjugated linoleic acid (CLA)

  • Beef is one of the best dietary sources of conjugated linoleic acid (CLA), and grass-fed beef contains an average of 2 to 3 times more CLA than grain-fed beef. CLA is a type of polyunsaturated fatty acid (PUFA) that is found naturally in milk and meat products, primarily from ruminants such as cows or sheep.
  • Grain-based diets reduce the pH of the digestive system in ruminant animals, which inhibits the growth of the bacterium that produces CLA.
  • CLA exhibits potent antioxidant activity, and research indicates that CLA might be protective against heart disease, diabetes, cancer and immune disorders.

More vitamins and minerals

  • Grass-fed meat contains considerably more vitamins and minerals. When compared to grain-fed meat, grass-fed products are higher in B-vitamins, calcium, iron, magnesium, potassium and zinc.

Better source of antioxidants

  • Grass-fed meat contains considerably more of the antioxidants Vitamin E, glutathione, superoxide dismutase (SOD), and catalase than grain-fed meat. These antioxidants play an important role in protecting our cells from oxidation and damage.

Higher levels of carotenoids

  • Carotenoids, such as beta-carotene, are precursors to vitamin A that are found as yellow, orange and red pigments synthesized by plants. Grain-fed beef does not contain appreciable levels of carotenoids, because grains don’t contain them. However, cows that are pasture-raised and eat carotenoid-rich grass, incorporate significant amounts of these compounds into their tissues.
  • (Note: Fat color can be a good indicator of how nutrient-rich your meat is – carotenoids make the fat from grass-fed beef more yellow than the fat from grain-fed beef).

Less stress = healthier meat

  • When animals are switched from grass diets to grain diets, they can experience high levels of stress. This stress can cause a number of disorders, including a common but painful condition called “subacute acidosis.” Cattle with subacute acidosis kick at their bellies, go off their feed and eat dirt, causing feed-lot managers to add antibiotic drugs to the feed, something that is dangerous to people who eat this meat.

Ideal option for people who are gluten intolerant

  • People who are gluten intolerant may find that they do not feel well after consuming meats from grain-fed sources.
