Ask the Doc: Why is Grass-fed important?

Why is Grass-fed important?

By: Joan D Waters, Naturopathic Doctor

More and more people are eating and talking about grass-fed meat and poultry…is it just a fad?

Grass-fed meat and poultry and the eggs from pastured chickens provide a natural source of Vitamin K2. The intestinal flora in animals converts chlorophyll, the green pigment in forage, to Vitamin K2. Vitamin K2, not to be confused with Vitamin K1, which is needed for clotting, removes calcium from soft tissues and deposits it into bones and teeth by activating osteocalcin, a protein found in those tissues. When activated by Vitamin K2, Osteocalcin binds to calcium and draws that calcium into the bones and teeth. Vitamins A and D are needed to cause the osteoblasts, or bone-building cells, to secrete osteocalcin. Some people believe that the increased prevalence of atherosclerosis may be associated with the buildup of calcium in soft tissues brought about by the practice of feeding cattle grain, rather than grass. More research is needed to determine whether this is true.

Vitamin K2 can be obtained naturally by eating grass fed meats and poultry, the eggs from pastured chickens, and milk, butter and cheeses from cows that are grass fed. Natto, a fermented Asian food, is also a potent source of vitamin K2. Those who can’t consume dairy may make ghee from butter made from the milk of pastured cows. It is the presence of Vitamin K2 in fatty foods that gives them their deep yellow or orange color. The Vitamin K2 content of grass-fed but grain-finished beef is much lower than in grass fed beef. When buying ‘grass-fed’ meat in a store, you may have to ask whether they were grain-finished.

We need to support our local farmers and CSAs who fill this important niche in our ecosystem – by providing meat, poultry and eggs that contain adequate amounts of Vitamin K2. Conventionally raised and processed meats cost less to produce. The government subsidizes farmers who grow certain grains so this brings the cost of grain feed down. Farmers and ranchers can raise cattle up to butchering age much more quickly if they feed them grain rather than grass, so are able to minimize the labor costs of raising each individual head of cattle. Conventionally raised cattle are often given low doses of antibiotics, which can cause antibiotic resistant bacteria to grow in these cattle. Poultry are sometimes sprayed with chlorine to kill bacteria on them. We can usually avoid these perils in our food supply when we purchase local meat, poultry and eggs from our local farmer. More on these subjects in later posts.

If you choose to supplement with Vitamin K2, 45 mg of menaquinone-4 (MK-4) three times daily or 120 mcgs of menaquinone 7 (MK-7) once daily are the recommended doses. MK-7 has a longer half-life so needs to be taken only once per day. More is not necessarily better. Since calcium is utilized for clotting and for muscle contractility, including cardiac contractility, we need to release it from the soft tissues very gradually to avoid causing other health problems. For the body to utilize Vitamin K2, we also need Vitamins A, D and E. These vitamins are all fat-soluble so they will be absorbed better when taken with food, especially with oils.
