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. Scan down for earlier postings on vitamin E levels in animal feed. The graph below shows that grassfed beef has an overall fat content similar to antelope, deer, and elk. Is this page useful?

Summary References— See bottom of page. Almost half the meat and poultry sold in the US is likely to be contaminated by highly dangerous bacteria, according to research published this month April in the scientific journal, Clinical Infectious Diseases. The study estimates that 47 percent of the meat and poultry on US supermarket shelves contains the bacteria staphylococcus aureus "Staph".
It is not, however, among the four bacteria— Salmonella, Campylobacter, E. The researchers tested samples from 80 brands of beef, pork, chicken and turkey, purchased from 26 grocery stores in five major US cities. DNA tests from staph-infected samples suggest that the farm animals themselves were the major source of contamination.
The bacteria is not only linked to a number of human diseases, but is also resistant to at least three classes of antibiotics.

The British research showed that healthy volunteers who ate grass-fed meat increased their blood levels of omega-3 fatty acids and decreased their level of pro-inflammatory omega-6 fatty acids. These changes are linked with a lower risk of a host of disorders, including cancer, cardiovascular disease, depression, and inflammatory disease.
Interestingly, volunteers who consumed conventional, grain-fed meat ended up with lower levels of omega-3s and higher levels of omega-6s than they had at the beginning of the study, suggesting that eating conventional meat had been detrimental to their health. Volume , pages The meat and dairy products of animals raised on pasture are higher in omega-3s than animals raised in factory farms. A study of breast cancer survivors revealed that the women with the most ALA in their tissues—and therefore the most ALA in their diets—were one fourth as likely to have their cancers return as women with the least amount.
Most women who die from breast cancer die from a tumor that has metastasized, not from the original tumor. This is yet another reason to eat cheese, milk, and meat from pastured animals. Since the s, large-scale poultry producers have added arsenic to their poultry feed.
Although inorganic arsenic is a toxin, small amounts speed the growth of the birds, make their breast meat pinker, and kill certain bacteria. Is this practice harmful for humans? Chronic exposure to high levels of arsenic has been linked with cancer, heart disease, diabetes and a decline in brain function. But as long as poultry meat has fewer than 0. That ruling, set in the s, must be revised.
Within the past few years, studies show that arsenic is a more potent cancer promoter than first believed. It has to do with its effect on blood vessels. The reason that arsenic makes white meat pinker is that it increases the growth of blood vessels in the meat. The more blood, the pinker the color. Cancer cells cannot speed up their growth without the creation of new blood vessels to fuel them with nutrients. Arsenic does the trick, according to a study published in the journal Environmental Health Perspectives.
The European Union banned the use of arsenic in poultry production in Arsenic should be banned in all animal feed. Organic poultry and the poultry raised by Eatwild Producers are free of arsenic and other potentially harmful chemicals. Environmental Health Perspectives , Volume , number 4, So said French researcher Gerard Ailhaud, commenting on the results of a new study showing that mice fed the amount of omega-6 fatty acids present in the modern western diet grow fatter and fatter with each succeeding generation.
In the picture shown, the mouse on the left was raised on the high levels of omega-6 fatty acids and low levels of omega-3 fatty acids typical of the American diet.
In addition to being grossly overweight, it has the warning signs of diabetes. The healthy mouse on the right was raised on standard mouse chow. The two mice got equal amounts of exercise. The mice are the fourth generation to be raised on the two types of diet. Omega-6 fatty acids are essential for health, but the amount consumed by most Americans increases the risk of obesity, diabetes, inflammatory diseases, and cancer.
Omega-6s are most abundant in vegetable oils such as corn oil, safflower oil, and cottonseed oils. Olive oil is low in omega- 6 fatty acids. Few people realize that grain-fed animals are also a major source of omega-6s.
Meat and dairy products from animals fed a high-grain diet, which is the typical feedlot diet, have up to ten times more omega-6s than products from animals raised on their natural diet of pasture.
This study suggests that if we switch to food with a healthy balance of omega-6 and omega-3 fatty acids, we will be leaner and healthier, and so will our children, grandchildren, and great grandchildren. A Western-like fat diet is sufficient to induce a gradual enhancement in fat mass over generations. Journal of Lipid Research. Volume 51, pages Now, a study from the Journal of Clinical Nutrition says that the more full-fat dairy products people consume, the lower their risk of heart attack provided the cows were grass-fed.
The reason grass-fed milk is protective is that it has up to five times more conjugated linoleic acid or CLA. CLA is a healthy fat found in the meat and milk of grazing animals. People who eat grass-fed dairy products absorb the CLA and store it in their tissues. In this new study of over 3, people, those with the highest levels of CLA in their tissues had a fifty percent lower risk of heart attack than those with the lowest levels.
Keeping Bossy on grass could prevent more heart attacks than putting people on expensive pharmaceutical drugs with all their troubling side effects. Conjugated linoleic acid in adipose tissue and risk of myocardial infarction. The American Journal of Clinical Nutrition. Published ahead of print, May 12, Fresh pasture and dried grasses are the natural diet of all ruminant animals.
In factory farms, animals are switched to an unnatural diet based on corn and soy. In general, this means waste products from the manufacture of human food.
In particular, it can mean sterilized city garbage, candy, bubble gum, floor sweepings from plants that manufacture animal food, bakery, potato wastes or a scientific blend of pasta and candy. There is no cure for this progressive disorder of the central nervous system that affects movement, mood, and behavior. Beate Ritz, et al. American Journal of Epidemiology. Grass-fed beef is better for human health than grain-fed beef in ten different ways, according to the most comprehensive analysis to date.
Compared with grain-fed beef, grass-fed beef was:. Tissue proximate, fatty acid, vitamin and cholesterol content. 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. Vitamin D is best known for its role in building strong bones. New research shows that it can also enhance the immune system, improve mood, reduce blood pressure, combat cancer, and reduce the risk of some autoimmune disorders.
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. Note that this benefit comes only from hens that are free to graze fresh greens, eat bugs, and bask in the sun. Most of the eggs sold in the supermarket do not meet this criterion. Better yet, purchase them directly from your local farmer. Click on the following link, then scroll down to the yellow map of the United States.

Few people realize that the European Union has banned the import of all US poultry since This month, EU agriculture ministers voted to continue the ban despite aggressive pressure from the United States. The standard practice in the US poultry industry is to wash the carcasses in chlorinated water to kill bacteria. John Bowis from the UK was more outspoken. Meanwhile, hundreds of millions of US citizens are unwittingly playing that role.
In the s, scientists and food producers were creating the first plans to take poultry off family farms and raise them in confinement. It was a time of trial and error. In a experiment conducted by the U. Department of Agriculture, breeding hens were taken off pasture and fed a wide variety of feed ingredients. But when birds were fed these same inadequate diets and put back on pasture, their eggs were perfectly normal.
The pasture grasses and the bugs made up for whatever was missing in each of the highly restrictive diets. Take a cube of butter from your refrigerator, slice it with a knife, and spread it on a slice of bread. Did it coat the bread evenly or did it remain in hard lumps? Researchers have determined that the easier butter spreads, the better it is for your health. The firmness of butter depends on its ratio of saturated and unsaturated fat.
At refrigerator temperatures, saturated fat is hard and unsaturated fat is soft, or even liquid. Therefore, butter that is relatively easy to spread has less saturated, artery-clogging fat and more healthier unsaturated fat. Cows that get all their nutrients from grass have the softest butterfat of all. Butter from grass-fed cows also has more cancer-fighting CLA, vitamin E, beta-carotene, and omega-3 fatty acids than butter from cows raised in factory farms or that have limited access to pasture.
To find a local farmer who raises cows on grass, go to our Eatwild Directory of Farms and Ranches. Journal of Dairy Science , Eating red meat—but not white meat or fish—is linked with a moderately increased risk of colon cancer. Red meat has considerably more heme iron than its paler counterparts. Iron is essential for survival, but heme iron can irritate the lining of the colon and set up the preconditions for cancer.
Another possible link with red meat and cancer is the amount of oxidized fat in the meat. You create oxidized fat when you grill meat, sear it, or cook it above medium rare. Do you have to cut back on grilled sirloin steak and lamb chops to lower your risk of colon cancer?
Eating foods high in antioxidants along with the meat could do the trick. Research shows that antioxidants have the potential to neutralize the ill effects of both the iron and the oxidized fat.
For example, a study showed that eating spinach along with red meat eliminated all irritation of the colon. Now a study reveals that drinking a glass of red wine with your meal could do the same thing. It is likely that other foods high in antioxidants will offer similar protection. Does eating grass-fed meat also reduce your risk of colon cancer?
Meat from pastured animals has more antioxidants than feedlot meat, so it is a distinct possibility. To date, no one has studied this hypothesis. 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. Journal of Agriculture and Food Chemistry, June , As it turns out, all those choices of eggs at your supermarket aren't providing you much of a choice at all.
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:. Check Eatwild's Pastured Products Directory to find free-range eggs near you. A team of scientists from the USDA compared grassfed lambs with lambs fed grain in a feedlot.
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. 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.
CLA conjugated linoleic acid is a cancer-fighting fat that is most abundant in grassfed products. Two new European studies link a diet high in CLA with a lower risk of breast cancer. In Finland, researchers measured CLA levels in the serum of women with and without breast cancer. Those women with the most CLA had a significantly lower risk of the disease. Meanwhile, French researchers measured CLA levels in the breast tissues of women.
Once again, the women with the most CLA had the lowest risk of cancer. The most natural and effective way to increase your intake of CLA is to eat the meat and dairy products of grassfed animals. A case-control study in France. Now there's another good reason to purchase eggs from pastured poultry farmers: This information comes from a British study published in At the time, British consumers were concerned about the trend toward factory farming.
Specifically, they thought factory eggs might not be as nutritious as eggs from free-ranging birds. An elaborate study confirmed their suspicions. The eggs from free-range hens contained significantly more folic acid and vitamin B12, as you can see by the graph below. The researchers also looked for differences in the fatty acid content of the eggs but did not find any. Now we know why. In the s, little was known about the benefits of omega-3 fatty acids, so the researchers didn't even bother to look for them in the eggs.
Tolan et al , "Studies on the Composition of Food, The chemical composition of eggs produced under battery, deep litter and free-range conditions. Nutrition , The goal of the commercial dairy industry is to coax the maximum amount of milk out of each cow through a high-tech combination of selective breeding, confinement housing, synthetic hormones, and a high-energy grain diet.
It has succeeded admirably. Today's super cows produce as much as 17, pounds of milk per cycle—20 times more milk than a cow needs to sustain a healthy calf. Unfortunately for consumers, the cow transfers a set amount of vitamins to her milk, and the greater her milk volume, the more dilute the vitamin content of the milk, especially vitamins E and beta-carotene. According to the journal article cited below, "It follows that continuing breeding and management systems that focus solely on increasing milk and milk fat yield will result in a steady dilution in the milk fat of these vitamins and antioxidants Dairy cows raised on pasture and free of hormone implants produce less milk than commercial cows, but the milk is therefore richer in vitamin content.
This is one of those times when less is more. Until recently, all of the experiments demonstrating the cancer-fighting properties of CLA conjugated linoleic acid have used synthetic CLA.
To see whether the CLA that occurs naturally in cow's milk has similar cancer-fighting properties, researchers recently compared the two. They fed one group of rats butter that was high in CLA and fed another group of rats an equivalent amount of synthetic CLA. As one would expect, the natural CLA proved to be just as effective in blocking tumor growth as the man-made variety. In both cases, cancer yield was reduced by about 50 percent. However, the high CLA butter had an added benefit: Researchers believe that the rats were converting another "good" fat found in the butter, trans-vaccenic acid or TVA, into CLA, giving them a second helping of this cancer-fighting fat.
Click here for more information about TVA. Japanese importers place a premium on beef with ultra-white fat, which is difficult for New Zealand ranchers to achieve because they fatten their cattle on pasture. Grass is rich in the antioxidant vitamin beta-carotene, which lends a healthy, creamy color to meat fat.
In a recent experiment, New Zealand researchers experimented with taking cattle off pasture and fattening them American-style on grain. Because grain is more expensive in New Zealand than it is in the States, grain-feeding was limited to less than 2 months. The fat color did not change appreciably, even though serum levels of beta-carotene dropped 97 percent. What's more, 1 the animals weighed less than animals that were allowed to stay on pasture, 2 their meat was tougher, and 3 the meat lost more moisture when cooked.
The scientists concluded that animals need to be fed grain for a longer period of time to use up all the beta-carotene stored in the fat.
Also, longer grain-feeding is required to overcome the initial weight loss of cattle that are switched from pasture to a feedlot diet. The increased toughness was unexpected and without explanation. 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.
When cattle are free to forage on their natural diet of grass, their meat is almost as lean as wild game. The graph below shows that grassfed beef has an overall fat content similar to antelope, deer, and elk. This second 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. Data for both graphs comes from G.
Some commercial feedlots feed stale candy to cattle in an effort to reduce costs. According to a recent review, milk chocolate and candy "are often economical sources of nutrients, particularly fat. They are sometimes fed in their wrappers. Candies, such as cull gummy bears, lemon drops, or gum drops are high in sugar content.
As long as beef producers are not accountable for the ultimate nutritional value of the meat, they will continue to formulate feedlot diets on a least cost basis and American consumers will continue to eat meat that is artificially high in fat and low in vitamin E, beta carotene, omega-3 fatty acids, and CLA.
Beef and buffalo jerky fit well into a busy lifestyle. Jerky needs no refrigeration and can be easily tucked into a pocket, purse, or lunch bag to provide a satisfying, high-protein snack. When the jerky is made from the meat of grassfed animals, you're also getting superior nutritional value and no questionable additives.
If you're purchasing grassfed meat in quantity, consider making your own jerky. Be aware, however, that most traditional recipes do not specify the high temperatures necessary to eliminate the risk of E. To solve the problem, food scientists from Colorado State University Cooperative Extension developed three different recipes for making safe jerky at home.
No time to make jerky? Order it ready made from one of five different suppliers in the Eat Wild Pastured Products Directory Click on the directory and then use your browser to search in the page for the word "jerky. In yet another short-sighted experiment, researchers at Washington State University are feeding recycled restaurant grease to feedlot cattle in an attempt to raise the CLA levels of their meat.
Although grease will indeed enhance CLA levels, it cannot compete with grass when the total nutritional value of the meat is taken into consideration. Meat from cattle raised on grass and legumes is not only five times higher in CLA than meat from feedlot cattle, it is also higher in vitamin E, beta carotene, and omega-3 fatty acids.
Also, restaurant grease is high in a type of fat called "linoleic acid" or LA that is known to stimulate tumor growth. Although grease-fed cattle will have more of the cancer-fighting CLA, they will also have higher levels of the cancer-promoting LA, perhaps canceling out the anticipated benefits.
As long as researchers focus on artificial ways to raise CLA levels in animals, we will continue to have beef that is nutritionally inferior in other areas. We will also be plagued with all the problems linked with the feedlot industry including nutrient leaching, odor, diseased animals, and the indiscriminate use of growth promoting hormones and antibiotics. Martin Marchello at the Carrington Research Extension Center has found that grassfed bison have as much as four times more selenium an essential trace mineral than grainfed bison.
Eating just three ounces of grassfed bison, for example, can give you over mcg. Most of the selenium research has focused on its potential to reduce the risk of cancer, but a study found that selenium also promotes a sunnier disposition! In this study, volunteers were given either micrograms of selenium or a sugar pill.
Those who were given the selenium noticed an improved mood in just two weeks. Eating a small portion of grassfed bison on a daily basis should produce the same results. Conjugated linoleic acid or CLA has demonstrated a multitude of benefits in animal studies, including fat reduction, increase in lean muscle mass, reduced risk of diabetes, reversal of arteriosclerosis, and a marked reduction in tumor growth.
Many people do not realize, however, that there are 16 different types of CLA, each with a slightly different molecular shape. New research reveals that each type of CLA has a different set of benefits.
The type of CLA most abundant in meat and dairy products referred to by chemists as "cis-9, trans, CLA" appears to be the champion cancer fighter. Compared with another common type of CLA trans 10, cis 12, CLA it was a third more effective in blocking the growth of human cancer cells.
But the type of CLA found in meat and dairy products does not appear to reduce fat or increase lean muscle mass in humans. That property is linked with trans 10, cis 12, CLA.
It will be some time before researchers match each type of CLA with its particular benefits. Information gleaned from abstracts presented at the 91st American Oil Chemists Society April , annual meeting. Special supplement to Inform , vol 11, no 5, French cheeses are among the most carefully crafted and coveted in the world. Now there's another reason to seek them out: A survey found that CLA levels in French cheese range from 5.
American cheese from conventional dairies has half this amount, with levels ranging from 2. Typically, American dairies raise their cows in confinement and feed them a grain-based diet. French dairies are more likely to raise their cows on pasture, resulting in naturally high levels of CLA.
Evidence is mounting that dairy products from grassfed cows supply yet another "good" fat to our diettrans-vaccenic acid or TVA. Technically, TVA is classified as a "trans-fatty acid," a type of fat nutritionists tell us to avoid. But TVA appears to behave differently from the man-made fat that comes from the hydrogenization of vegetable oil.
Unlike the trans-fatty acids found in fast foods and margarine, TVA is not linked with an increased risk of cardiovascular disease and may help inhibit tumor growth and obesity. Schingoethe and colleagues are experimenting with increasing TVA in dairy cows by feeding them fish meal and soybeans. But raising cows on fresh pasture and withholding all grain may prove just as effective.
Milk from grassfed Irish cows is 2—3 times higher in conjugated linoleic acid CLA than milk from grainfed American cows. It will take only 2 minutes to fill in. Skip to main content. Home Health and social care Health improvement.
