Here's some scientific jargon you can throw around during Missouri parties or at work to impress your friends and associates: “Omega 3 and 6, and CLA's.” Now sit down, this get's thick. Following is a "simple" explanation from Kate Clancy, a senior scientist in the Union of Concerned Scientists - from a March 2006 publication called "Greener Pastures: How grass-fed beef and milk contribute to healthy eating."

  • 1. What are "CLAs" and "Omega 3 and 6s"?!?Heres some scientific jargon you canthrow around during Missouri parties or atwork to impress your friends andassociates: “Omega 3 and 6, and CLAs.”Now sit down, this gets thick. Following isa "simple" explanation from Kate Clancy, asenior scientist in the Union of ConcernedScientists - from a March 2006 publicationcalled "Greener Pastures: How grass-fedbeef and milk contribute to healthyeating." The three omega-3 fatty acids—the so-called beneficial fatty acids—have been shown in many studies to improve health and prevent disease in humans. CLA has attracted attention because it has demonstrated many beneficial effects in animal studies. We have focused on the levels of these fats in milk and meat from pasture-raised cattle because, beyond their intrinsic value, widespread interest in these substances among health-conscious consumers could help shift American agriculture from conventional to pasture-based feeding systems. (pg 1)and We reviewed all the studies published in English we could find that compare levels of fatty acids in pasture-raised milk and meat with levels in conventionally produced milk and meat, and converted these levels into amounts per serving of milk, steak, and ground beef. The resulting analysis found statistically significant differences in fat content between pasture-raised and conventional products. Specifically: • Steak and ground beef from grass-fed cattle are almost always lower in total fat than steak and ground beef from conventionally raised cattle. • Steak from grass-fed cattle tends to have higher levels of the omega-3 fatty Visit for more information.
  • 2. acid ALA. • Steak from grass-fed cattle sometimes has higher levels of the omega-3 fatty acids EPA and DHA. • Ground beef from grass-fed cattle usually has higher levels of CLA. • Milk from pasture-raised cattle tends to have higher levels of ALA. • Milk from pasture-raised cattle has consistently higher levels of CLA. At this point, the evidence supporting the health benefits of omega-3 fatty acids and CLA is mixed; the data are stronger for some fatty acids than for others. The strongest evidence, encompassing animal studies as well as experimental and observational studies of humans, supports the effects of EPA/DHA on reducing the risk of heart disease. ALA also appears to reduce the risk of fatal and acute heart attacks, but no other beneficial effects have been shown conclusively. Finally, animal research on CLA has shown many positive effects on heart disease, cancer, and the immune system, but these results have yet to be duplicated in human studies. (pg 2)So - to boil that all down: 1. Some scientists have done some studies - not all of these on humans - which say that higher CLAs and Omega 3/6 ratios are better for you. 2. Grass-fed beef has higher CLAs and Omega 3/6 ratios. 3. If you believe these studies, then you might get healthier from eating grass fed beef.Now I could go on and bore you to tears about how Belted Galloways are inherently better atthis because they build leaner beef than straight Angus, and thats why our beef is striped. Andalso I could tell you that just feeding any beef a corn ration for as little as a month will wipeout all that higher CLA and Omega 3 levels. As well, Ive been told that this stuff doesnt makea dingleberrys bit of difference, since it isnt proved on humans anyway.I really dont care.I like the taste of grass fed beef more than corn-fed. And its cheaper to raise andbetter for the environment and my farm in particular.So if you dont believe in CLAs or Omega 3/6 ratios or the Tooth Fairy or Santa Claus - youcan still eat great-tasting beef and quote scientists who say they do.Either way, you get a great-tasting meal. ---- For more data on raising pasture fed beef, as well as other information on prime beef as health food – visit Visit for more information.
  • 3. About Worstell FarmsOur family goes back on both sides withfarmers. As far as we can trace.And that tradition came to Mexico,Missouri around 1960 to purchase thecurrent farming operation.Jim and Laura Worstell established aworking farm there and then, and raised abig family of 8 kids, along with severaldogs, cats, and an occasional pet squirrelor raccoon. And dont forget the llamasand peacocks...In 2000, Robert Worstell returned to thefarm to take over operations management(as well as the day-to-day chores) andshares these duties with his mother and sister (well, not the chores, so much.)On approximately 250 acres of land, which is mixed hillsides, bottom, and woods, we raise acombination of annual row-crops and also our beef. Typical of this area, we have marginalland which is better suited to cattle than cultivation (which is typical of most cattle-farming).Weve found that where we run our cattle actually improves the soil and its health - as long aswe pay attention and actually manage how long and when they graze where. As we continue tostudy and learn about and from our cattle, our daily lessons help us to improve the quality andquantity of beef we raise.We practice managed grazing and are transitioning over to ultra-high-density stocking, as this is even better for the land and actually requires more cattle peracre to keep up with the lush growth and pasture renovation.All our beef is from local stock. Mostly black Angus cross-bred cows, with our current BeltedGalloway bull named "Gene Autry" is servicing these well.Ordering Our BeefWe only take local orders, so contact us via the website or call directly. Due to Federal laws,we cannot sell our beef out of Missouri – youll have to buy it here. Generally, our beef isspoken for well before its ready for processing. However, contact us for what we have comingup and we can give you an estimate on when the next one is coming available. We are also offering La Cense beef, which is USDA inspected and can be shipped anywhere in the US. Please see for details. Visit for more information.

The results showthat grass fed beef, locally and directly marketed is the route to profitability, not followingcommodity trends.Dr. Worstells training in web design has helped him move the operation more online, as wellas giving him new networking opportunities to promote Worstell Farms beef products. He isalso a prolific author and has recently completed research into the all-time best self helpbooks, with his “Freedom Is – (period).” Out of the 7 books published this year, hes alsoproduced a fiction work, “The Dreamer Dreamed” - itself a breakthrough use of fiction toexplore the metaphysical aspect of dream meaning.
