Grassfed Animal Products

Jo Robinson

Jo Robinson, an investigative journalist and New York Times best-selling writer, is the author of the new book, Pasture Perfect, and the principal researcher and writer for the eatwild.com web site. Jo has spent the last four years researching the many benefits of raising animals on pasture. Her interest grew out of a previous book, The Omega Diet, co-authored with Dr. Artemis Simopoulos, that explores the health benefits of the Mediterranean diet. While researching the book, Jo learned that meat from pasture-raised animals is very similar to meat from wild game and that both promote optimal health. Starting with this insight, she began an exhaustive search of the scientific literature from the 1960s to the present. To date, she has identified hundreds of peer-reviewed studies showing that raising animals on pasture is good for the animals, the environment, farm families, and the health of consumers. She gives talks to ranchers, government agencies, sustainable agricultural groups, and the general public around the country. Jo has been interviewed by scores of journalists and reporters about the benefits of raising animals on pasture. Jo's recent book, When Your Body Gets the Blues, extends her interest in natural health to human psychology. Working with Dr. Marie-Annette Brown from the University of Washington, she developed a clinically proven, all-natural program that boosts women's mood and energy level and tames their appetite. Jo lives on Vashon Island in Washington State. She has plans to develop a test garden featuring plants with exceptional nutritional value that are similar to plants growing in the wild Jo is the author of Pasture Perfect and Why Grassfed Is Best! and the co-author of Unplug the Christmas Machine (with Jean Staeheli) Getting the Love You Want (with Dr. Harville Hendrix), Hot Monogamy and Emotional Incest (with Dr. Pat Love), The Omega Diet (with Dr. Artemis Simopoulos), and When Your Body gets the Blues (with Dr. Marie-Annette Brown.) Jo frequently gives talks about the benefits of grass farming to ranchers, government agencies, sustainable agriculture groups, and the general public.

When you switch from grainfed to grassfed animal products, you instantly create a more nutritious, wholesome diet. First of all, you eliminate a lot of "bad" fat from your diet. When cattle, sheep, and bison are raised on pasture, their meat is naturally very lean. For example, a sirloin steak from a grassfed steer has about one half to one third the amount of fat as a similar cut from a grainfed steer. In fact, grassfed meat has about the same amount of fat as skinless chicken or wild deer or elk. When meat is this lean, it actually lowers your LDL (bad) cholesterol levels.

Because grassfed meat is so lean, it is also lower in calories. A six-ounce steak from a grass-finished steer has almost 100 fewer calories than a similar steak from a grainfed steer. If you eat a typical amount of beef (66.5 pounds a year), switching to grassfed beef will save you 17,733 calories a year-without requiring any willpower or change in eating habits. If everything else in your diet remains constant, you'll lose about six pounds a year. If all Americans switched to grassfed meat, our national epidemic of obesity might begin to diminish.

Extra Omega-3s

Although grassfed meat is low in "bad" fat (including saturated fat), it gives you from two to six times more of a type of "good" fat called "omega-3 fatty acids." Omega-3 fatty acids play a vital role in every cell and system in your body. For example, of all the fats, they are the most "heart friendly." People who have ample amounts of omega-3s in their diet are less likely to have high blood pressure or an irregular heartbeat. Remarkably, they are 50 percent less likely to have a serious heart attack. Omega-3s are essential for your brain as well. People with a diet rich in omega-3s are less likely to be afflicted with depression, schizophrenia, attention deficit disorder (hyperactivity), or Alzheimer's disease.

Another benefit of omega-3s is that they may reduce your risk of cancer. In animal studies, these essential fatty acids have slowed the growth of a wide array of cancers and kept them from spreading. Although the human research is in its infancy, researchers have shown that omega-3s can slow or even reverse the extreme weight loss that accompanies advanced cancer. They can also hasten recovery from cancer surgery. Furthermore, women with breast cancer who have high levels of omega-3s in their tissues may respond better to chemotherapy than women with low levels.

Omega-3s are most abundant in seafood and certain nuts and seeds such as flaxseeds and walnuts, but they are also found in grassfed animal products. The reason that grassfed animals have more omega-3s than grainfed animals is that omega-3s are formed in the green leaves (specifically the chloroplasts) of plants. 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 omega-3s. Each day that an animal spends in the feedlot, its supply of omega-3s is diminished.

When chickens are housed indoors and deprived of greens, their meat and eggs also become artificially low in omega-3s. Eggs from pastured hens can contain as much as 20 times more omega-3s than eggs from factory hens. They are also higher in vitamin E and carotenes. (The carotenes give the eggs a rich, almost orange yolk.)

Switching our livestock from their natural diet of grass to grain is one of the hidden reasons our modern diet is so deficient in these essential fats. It has been estimated that only 40 percent of Americans consume a sufficient supply of these nutrients. Twenty percent have levels so low that they cannot be detected. Switching to grassfed animal products is one way to restore this vital nutrient to your diet.

The CLA Bonus

The meat and milk from grassfed ruminants are the richest known source of another type of good fat called "conjugated linoleic acid" or CLA. When ruminants are raised on fresh pasture alone, their milk and meat contain as much as five times more CLA than products from animals fed conventional diets.

CLA may be one of our most potent defenses against cancer. In laboratory animals, a very small percentage of CLA - a mere 0.1 percent of total calories -greatly reduces tumor growth. Researcher Tilak Dhiman from Utah State University estimates that you may be able to lower your risk of cancer simply by eating the following grassfed products each day: one glass of whole milk, one ounce of cheese, and one serving of meat. You would have to eat five times that amount of grainfed meat and dairy products to get the same level of protection.

Vitamin E

In addition to being higher in omega-3s and CLA, meat from grassfed animals is four times higher in vitamin E. In humans, vitamin E is linked with a lower risk of heart disease and cancer. This potent antioxidant may also have anti-aging properties. Most Americans are deficient in vitamin E.
