According to www.eatwild.com, there are numerous benefits provided by grass-fed beef dairy and eggs.
Grass-fed beef is naturally leaner, lower in fat and calories, than grain-fed beef. Animals fed on grass also have significantly higher amounts of omega-3 fatty acids - two to four times as much - than their grass-fed counterparts. The effect of pasteurizing is even more pronounced in chickens. The eggs from chickens who are allowed to pasture contain up to ten times more omega-3s than those fed exclusively grain.
Grass-fed meat and dart products also contain higher amounts of CLA, or conjugated linoleum acid. In fact, they may be the richest sources of CLA, a healthy fat that is missing from many diets.
Finally, grass-fed animals are a better source of vitamin E. Vitamin E is a great antioxidant, and grass-fed cattle can have up to four times the vitamin E levels as conventionally raised cattle.
The following was taken directly from the eatwild.com website, a great source for increasing your knowledge of, and finding access to, grass-fed meat and dairy products.
Score Ten for Grass-Fed Beef
Grass-fed beef is better for human health than grain-fed beef in ten different ways, according to the most comprehensive analysis to date. The 2009 study was a joint effort between the USDA and researchers at Clemson University in South Carolina. Compared with grain-fed beef, grass-fed beef was:
1. Lower in total fat
2. Higher in beta-carotene
3. Higher in vitamin E (alpha-tocopherol)
4. Higher in the B-vitamins thiamin and riboflavin
5. Higher in the minerals calcium, magnesium, and potassium
6. Higher in total omega-3s
7. A healthier ratio of omega-6 to omega-3 fatty acids (1.65 vs 4.84)
8. Higher in CLA (cis-9 trans-11), a potential cancer fighter
9. Higher in vaccenic acid (which can be transformed into CLA)
10. Lower in the saturated fats linked with heart disease
