Cattle, like all other ruminants and many other critters, developed on this Earth eating green leafy plants, mostly grass. They ate virtually no grain. In fact, there isn’t a livestock species on this planet that evolved eating grain! This is important since scientists are reporting that many of American’s leading health problems are due to diets top heavy in Omega-6 fatty acids versus the Intake of Omega-3 Fatty acids.

Omega-6 Fatty acids come mainly from grains which is also deficient in Omega-3 Fatty acids. Omega-3 fatty acids, and the appropriate balance of omega-6 fatty acids, come mainly from green leafy plants and some nuts. Fatty Acids scientific experiments determined that if the ratio of Omega-6 Fatty acids to Omega-3 Fatty acids in cell membranes exceeds 4:1, people develop more health problems. This is especially meaningful since grain-fed beef can have ratios that exceed 15:1 whereby grass-feed beef is down around 1:1. The health problems associated with diets high in Omega-6 and low in Omega-3 are: Cancer, heart disease, depression, obesity, insulin resistance, allergies, autoimmune diseases such as lupus and arthritis, diabetes, attention deficient syndrome, and the list goes on. These diseases are not associated with bacterial infections. They are bodies failing, not from aging, but from improper diets.

The food provided might be a lot of food..But with none of the actual nutrients needed to sustain a healthy life.  Grass fed beef is full of beta carotene, Loaded with 400% more of vitamin A and E, devoid of any risk of Mad Cow Disease.  One of the MOST important reasons to eat Grass fed beef is the natural, and high amounts off, according CLA’s (Conjugated Linoleic Acid). CLA is a naturally occurring fat found in animal and dairy fats such as beef and poultry that are not fed grains. As soon as you start to feed cattle grain they start to lose their ability to produce CLA. Animals that graze on pasture have from 300 to 400% more CLA than animals fattened on grain in a feedlot. he human intestine produces CLA naturally from linoleic acid. Recent studies have been conducted on attaining a higher CLA content in daily food intake because of possible health benefits such as weight loss. CLA is a newly discovered good fat called "conjugated linoleic acid" that may be a potent cancer fighter. In animal studies, very small amounts of CLA have blocked all three stages of cancer: 1) initiation, 2) promotion, and 3) metastasis. Most anti-cancer agents block only one of these stages. What's more, CLA has slowed the growth of an unusually wide variety of tumors, including cancers of the skin, breast, prostate, and colon. Human CLA research is in its infancy, but a few studies have suggested that CLA may have similar benefits in people. A recent survey determined that women with the most CLA in their diets had a 60 percent reduction in the risk of breast cancer. The most abundant source of natural CLA is the meat and dairy products of grassfed animals. Research conducted since 1999 shows that grazing animals have from 3-5 times more CLA than animals fattened on grain in a feedlot. Simply switching from grainfed to grassfed products can greatly increase your intake of CLA

A lean hamburger from grass-fed cattle has two and a half times more conjugated linoleic acid (CLA) than an equally lean hamburger from cattle raised in a feedlot.

Riserus, U., P. Arner, et al. (2002). "Treatment with dietary trans10cis12 conjugated linoleic acid causes isomer-specific insulin resistance in obese men with the metabolic syndrome." Diabetes Care 25(9): 1516-21.

OBJECTIVE: Conjugated linoleic acid (CLA) is a group of dietary fatty acids with antiobesity and antidiabetic effects in some animals. The trans10cis12 (t10c12) CLA isomer seems to cause these effects, including improved insulin sensitivity. Whether such isomer-specific effects occur in humans is unknown. The aim of this study was to investigate whether t10c12 CLA or a commercial CLA mixture could improve insulin sensitivity, lipid metabolism, or body composition in obese men with signs of the metabolic syndrome. RESEARCH DESIGN AND METHODS: In a randomized, double-blind controlled trial, abdominally obese men (n = 60) were treated with 3.4 g/day CLA (isomer mixture), purified t10c12 CLA, or placebo. Euglycemic-hyperinsulinemic clamp, serum hormones, lipids, and anthropometry were assessed before and after 12 weeks of treatment. RESULTS: Baseline metabolic status was similar between groups. Unexpectedly, t10c12 CLA increased insulin resistance (19%; P < 0.01) and glycemia (4%; P < 0.001) and reduced HDL cholesterol (-4%; P < 0.01) compared with placebo, whereas body fat, sagittal abdominal diameter, and weight decreased versus baseline, but the difference was not significantly different from placebo. The CLA mixture did not change glucose metabolism, body composition, or weight compared with placebo but lowered HDL cholesterol (-2%; P < 0.05). CONCLUSIONS: These results reveal important isomer-specific metabolic actions of CLA in abdominally obese humans. A CLA-induced insulin resistance has previously been described only in lipodystrophic mice. Considering the use of CLA-supplements among obese individuals, it is important to clarify the clinical consequences of these results, but they also provide physiological insights into the role of specific dietary fatty acids as modulators of insulin resistance in humans.
