WHY CHOOSE GRASS FED?
We’ve heard it countless times: You are what you eat. So it should come as no surprise that what you eat is what it eats, too. It’s a remarkably simple concept: the nutritional value of an animal product is directly influenced by the animal’s diet. Therefore, say advocates of the rapidly growing Grass-fed movement, the animal’s diet should be as biologically natural and as packed full of nutrients as possible, right? Apparently not, if you’re in the U.S. commercial meat business. The truth is that a vast majority of our country’s commercially raised ruminants — cattle, sheep, goats and bison — are raised in feedlots, fed a grain-based diet and, typically, treated with hormones, feed additives and low-level antibiotics.
But the move toward grass-fed is about more than just animal welfare. It’s about human health. Inappropriately feeding animals dry grain is a direct contributor to those animals developing pathogens such as E. coli (in cattle) and Salmonella (in poultry). And if that isn’t convincing enough, consider that mad cow disease is unknown among cattle fed entirely on pasture and hay.
HOW CAN EATING GRASS-FED ANIMAL PRODUCTS IMPROVE MY HEALTH?
Meat and dairy products from grass-fed animals are just plain more nutritious than grain-fed animal products. Research suggests that switching to grass-fed products may reduce our risk of a number of diseases, including diabetes, obesity, cardiovascular disease, allergies, auto-immune disorders, Alzheimer’s disease and cancer.
• Lower fat content means lower LDL cholesterol levels. A sirloin steak from a grass-fed steer has about one half to one third as much fat as a similar cut from a grain fed steer. In fact, grass-fed meat has about the same fat content as skinless chicken, wild deer or elk.[1] Meat this lean can actually lower your LDL cholesterol levels.[2]
• Extra Omega-3s – secret weapon in the battle against heart attacks, cancer, Alzheimer’s and more. Grass-fed meat has two to six times more omega-3 fatty acids than grain-fed meat. Why is this good? Ample amounts of omega-3s decreases your chances of developing high blood pressure, an irregular heartbeat or a heart attack.[3] They’re also an essential brain food. Those with a diet rich in omega-3s are less likely to suffer from depression, schizophrenia, attention deficit disorder or Alzheimer's disease.[4] And researchers are now finding that omega-3s may reduce your risk of cancer, as well — animal studies indicated that omega-3s not only slowed the growth of a wide variety of cancers but kept them from spreading.[5]
• Grass-fed ruminants cultivate conjugated linoleic acid (CLA). Meat and dairy products from grass-fed ruminants are the richest known source of CLA. When ruminants are raised on fresh pasture alone, their products contain from three to five times more CLA than products from animals fed conventional diets.[6] By finishing our cattle on grain, we are depriving ourselves of one of nature’s most potent defenses against cancer. Consider the following: A Finnish study found th
at women with the highest levels of
CLA in their diet had a 60 percent lower risk of breast cancer than
those with the lowest levels.[7]
• Vitamin E – healer, antioxidant, anti-aging support. Meat from pastured cattle is four times higher in vitamin E than meat from feedlot cattle and, ironically, almost twice as high as meat from feedlot cattle given vitamin E supplements.[8] In humans, most of whom are deficient in it, vitamin E is linked with a lower risk of heart disease and cancer.
The animals we raise for meat and other products are not naturally suited to a diet of corn and soybeans, nor are they suited to consuming the remains of other animals. They are ruminants, animals whose diet staples are fresh grass and other leaves. The grass-fed movement aims to move us toward a more natural, healthy and nutritionally effective diet and to remind us, we are not only what we eat, but what it eats, as well.

I've heard that animals raised on real farms are much better for you but I mostly have just heard about the antibiotics that lead to pus in all the milk from cows. It's really appalling that just to earn a profit animals should be abused so much, and it doesn't even benefit us. Grass-fed animals are naturally better so we're doing no favors for ourselves by raising these animals that are sicker and less nutritional. It's a shame that the more organic food gets, the more expensive it gets too.

I wonder if anyone has studied the health benefts of milk from grass-fed cows vs. grain fed? I expect that the health benefits would be similar. We lived in NZ for 8 years, and dairy cows are grass fed. The milk definitely tastes different - my husband went back for a visit last September and couldn't believe the difference. I'm on the look out for grass-fed milk here now. Unfortunately 'organic' does not equal grass-fedl.
