Meat, eggs, and dairy products from pastured animals are ideal for your health. Compared with commercial products, they offer you more "good" fats, and fewer "bad" fats. They are richer in antioxidants; including vitamins E, beta-carotene, and vitamin C. Furthermore, they do not contain traces of added hormones, antibiotics or other drugs.
Lower in Fat and Calories. There are a number of nutritional differences between the meat of pasture-raised and feedlot-raised animals. To begin with, meat from grass-fed cattle, sheep, and bison is lower in total fat. If the meat is very lean, it can have one third as much fat as a similar cut from a grain-fed animal. In fact, as you can see by the graph , grass-fed beef can have the same amount of fat as skinless chicken breast, wild deer, or elk.[1] Research shows that lean beef actually lowers your "bad" LDL cholesterol levels.[2]
Lean beef is also high in CoQ10 for heart health.
Because meat from grass-fed animals is lower in fat than meat from grain-fed animals, it is also lower in calories. . But it is only part of the story. The saturated fat from pastured beef is healthy fat. The kind of fat that our body uses for just about everything
In the past few years, producers of grass-fed beef have been looking for ways to increase the amount of marbling in the meat so that consumers will have a more familiar product. And these fatter cuts of grass-fed beef are not only lower in fat and calories than beef from grain-fed cattle, but they also contain the so much desired Omega-3 fatty acid, which we need despeartely since our western diet is loaded with Omega-6's from the vegetable oils . A very unstable polyunsaturated fat that is prone to oxidation and is causing a lot of health problems.
Extra Omega-3s. Meat from grass-fed animals has two to four times more omega-3 fatty acids than meat from grain- fed animals. Omega-3s are called "good fats" because they 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 suffer a heart attack.[3] Omega-3s are essential for your brain as well. People with a diet rich in omega-3s are less likely to suffer from depression, schizophrenia, attention deficit disorder (hyperactivity), or Alzheimer's disease.[4]
Another benefit of omega-3s is that they may reduce your risk of cancer. In animal studies, these essential fats have slowed the growth of a wide array of cancers and also kept them from spreading.[5] 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 and also hasten recovery from surgery.[6,7]
Omega-3s are most abundant in seafood and certain nuts and seeds such as flaxseeds and walnuts, but they are also found in animals raised on pasture. The reason is simple. Omega-3s are formed in the chloroplasts of green leaves and algae. Sixty percent of the fatty acids in grass are omega-3s. When cattle are taken off omega-3 rich grass and shipped to a feedlot to be fattened on omega-3 poor grain, they begin losing their store of this beneficial fat. Each day that an animal spends in the feedlot, its supply of omega-3s is diminished.[8] The graph above illustrates this steady decline.
Free Range Eggs Nutritionally Superior
It is exactly the same story with chickens and eggs. 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 10 times more omega-3s than eggs from factory hens.[9] Plus eggs from hens raised outdoors on pasture have from three to six times more vitamin D than eggs from hens raised in confinement. Pastured hens are exposed to direct sunlight, which their bodies convert to vitamin D and then pass on to the eggs. (See Note to the Left)
Recent tests conducted by Mother Earth News magazine have shown once again that eggs from chickens that range freely on pasture provide clear nutritional benefits over eggs from confinement operations.
Mother Earth News collected samples from 14 pastured flocks across the country and had them tested at an accredited laboratory. The results were compared to official US Department of Agriculture data for commercial eggs. Results showed the pastured eggs contained an amazing:
1/3 less cholesterol than commercial eggs
1/4 less saturated fat
2/3 more vitamin A
2 times more omega-3 fatty acids
7 times more beta carotene
Full results of the tests are available in the October/November 2007 issue of Mother Earth News, or on their website at http://www.MotherEarthNews.com/eggs
It has been estimated that only 40 percent of Americans consume an adequate supply of omega-3 fatty acids. Twenty percent have blood levels so low that they cannot be detected.[10] Switching to the meat, milk, and dairy products of grass-fed animals is one way to restore this vital nutrient to your diet
And there is even more good news!!
Currently, it is estimated that one in three adults in the United States has hypertension. Hypertension, or high blood pressure, is defined as an untreated blood pressure of 140/90 mmHg or higher, a patient taking anti-hypertensive medication, or at least two elevated blood pressure readings recorded by a healthcare professional.
In a recent clinical trial, researchers investigated the effects of supplementation with conjugated linoleic acid (CLA) in obese hypertensive subjects. In this double-blind, placebo-controlled study, 80 obese subjects with uncontrolled essential hypertension were given 4.5 grams per day CLA plus 37.5 mg per day of ramipril, or 37.5 mg per day ramipril plus placebo for 8 weeks. Ramipril is an anti-hypertensive medication that acts by inhibiting the angiotensin-converting enzyme (ACE inhibitor).
However we don't have to use supplements when we have access to pasture fed beeft.
It Is called The CLA Bonus. Meat and dairy products from grass-fed 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 products contain from three to five times more CLA than products from animals fed conventional diets.[11] (A steak from the most marbled grass-fed animals will have the most CLA ,as much of the CLA is stored in fat cells.)
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 reduced tumor growth. [12] There is new evidence that CLA may also reduce cancer risk in humans. In a Finnish study, women who had the highest levels of CLA in their diet, had a 60 percent lower risk of breast cancer than those with the lowest levels. Switching from grain-fed to grassfed meat and dairy products places women in this lowest risk category.13 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 grain-fed 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 also higher in vitamin E. The graph below shows vitamin E levels in meat from: 1) feedlot cattle, 2) feedlot cattle given high doses of synthetic vitamin E (1,000 IU per day), and 3) cattle raised on fresh pasture with no added supplements. The meat from the pastured cattle is four times higher in vitamin E than the meat from the feedlot cattle and, interestingly, almost twice as high as the meat from the feedlot cattle given vitamin E supplements. [14#] 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.
This latest good news about eggs comes from a study just released by Mother Earth News, a magazine that plays a leading role in promoting health-enhancing, natural foods. The editors found that eating just two eggs will give you from 63-126% of the recommended daily intake of vitamin D.
Yet another study shows that grass-fed meat is nutritionally superior to feedlot meat. This newest study examined the differences in fat content between four breeds of cattle that were either 1) raised on pasture or 2) given grain and other feedstuff in a feedlot.
As in previous research, the results showed that meat from cattle raised on pasture had much healthier fats. The researchers concluded that grass-fed meat is “clearly superior” and “remarkably beneficial.” They stated that grass-fed meat “should be promoted as an important part of a healthy balanced diet.” Read the study summary.

And thus the story continues!
In virtually all aspects pasture fed animals are better for our health than grainfed........
Soft cheese has more CLA than aged cheese

Pastured pigs are vitamin enriched — naturally

Egg yolks are the richest known source of lutein and zeaxanthin, essential vitamins not found in your multi-vitamin tablet
Eggs are gaining new respect from nutritionists, partly for their abundance of two carotenes --- lutein and zeaxanthin. These antioxidant vitamins are essential for the protection of the macula, an area of the retina that provides our best central vision. Eggs are the richest known source. "Macular degeneration," the term for damage to this area of the retina, is the leading cause of blindness in people over 55 years of age. Lutein and zeaxanthin protect the macula from the destructive effects of light. The deeper the yellow-orange color of yolks, the more lutein and zeaxanthin they contain and the more eye-protection they offer.
There is also new evidence linking lutein and zeaxanthin with a lower risk of colon cancer. According to a recent study, "Of all the carotenoids investigated, only lutein and zeaxanthin showed a protective effect against colon cancer, with an enhanced effect in younger people."

Interestingly, when the pasture was machine-harvested and then fed to the animals as hay, the cows produced far less CLA than when they were grazing on that pasture, even though the hay was made from the very same grass. The fat that the animals use to produce CLA is oxidized during the wilting, drying process. For maximum CLA, animals need to be grazing living pasture.

Why Grassfed Butter Is Better
Because living grass is richer in vitamins E, A, and beta-carotene than stored hay or standard dairy diets, butter from dairy cows grazing on fresh pasture is also richer in these important nutrients. The naturally golden color of grassfed butter is a clear indication of its superior nutritional value.

Why Grassfed Cheese Is Better
Cheese from grassfed cows is more than four times richer in conjugated linoleic acid—a cancer-fighting, fat-reducing fat—than cheese from standard, grain-fed cows. (Dhiman, T.R., "Conjugated linoleic acid: a food for cancer prevention." Proceedings from the 2000 Intermountain Nutrition Conference, pages 103-121.)
Pastured Poultry Get a Bounty of Vitamin E from Grass
Standard poultry feed is supplemented with small amounts of vitamin E. But as you can see by the graph below, it doesn't come close to the bounty of vitamin E that chickens glean from fresh pasture. This vitamin E gets passed on to the consumer. An egg from a pastured hen has 30 percent more vitamin E than the kind you buy in the supermarket.
(Lopez-Bote et al, "Effect of free-range feeding on omega-3 fatty acids and alpha-tocopherol content and oxidative stability of eggs." Animal Feed Science and Technology, 1998. 72:33-40.)
This graph shows that grain-fed beef has a much higher ratio of omega-6 to omega-3 fatty acids than wild game or grass-fed beef. A high ratio of omega-6 to omega-3 fatty acids has been linked with an increased risk of cancer, cardiovascular disease, allergies, depression, obesity, and auto-immune disorders. A ratio of four or lower is considered ideal. The ratio in grain-fed beef is more than 14 to 1. In grassfed beef, it is approximately two to one.
