Yesterday I had the opportunity to attend a farm tour around the Brookings area. We toured Baby Bel’s plant, a dairy, VanderWal’s feedlot, and the SDSU Cow/Calf Unit. It was a great day of learning and exploring where our food comes from and the practices involved of getting food to our tables. Dr. Russ Daly, DVM discussed some hot topics such as antibiotic and hormone use. I posted this write up below a few years ago and thought it was worthy of reposting as it addresses the hot topic of hormone use and beef. If you have any questions after reading the facts, please contact me. I am more than happy to help diminish the confusion on this topic!! 🙂
I recently came across a really well written, credible, and easy to understand article regarding hormones in beef. There are a lot of mixed messages and concerns about the use of hormones in our meat production. Hormones are found in all multi-cellular organisms, which does include animals, vegetables, etc. Sometimes producers will use hormone implants which cause the meat to have a little bit more hormones than a non-implanted animal. Federal laws prohibit the use of hormones in hogs and chickens, but it is permissible in beef. The reason producers use implants are to increase efficiency, meaning the cow will gain more muscle, from less feed, more quickly. This really helps keeps prices down of the meat and reduces environmental impact. When implanted, the meat will contain a slightly higher amount of estrogen in a 3 oz serving (1.9 nanograms compared to 1.3 nanograms in non implanted meat). Many people are concerned that the extra estrogen is causing a variety of other issues such as early puberty or faster growing children.
Now here’s where you you pay special attention: our own bodies produce hormones naturally, a child will produce around 50,000 nanograms of estrogen/day and an adult female will produce about 480,000 nanograms of estrogen a day. In addition, when hormones are eaten and digested, they are not able to act as hormones anymore….but even if they did, that 1.9 nanograms in a 3 oz serving of meat is pretty small compared to our own natural production. In addition, it’s important to point out that many other foods have much more estrogen in them naturally, such as potatoes have 225 nanograms, peas have 340 nanograms, icecream-520 nanograms,cabbage- 2000 nanograms, and soy milk has 11,250 nanograms (all based on 3 oz servings). Also, one birth control pill has about 35,000 nanograms of estrogen. So here’s the bottom line, the hormones found in implanted beef are miniscule compared to our own production of hormones and various other foods we normally eat. I personally, am not concerned about this practice and feel it is safe to consume and we shouldn’t have any concerns about it. Now if you are still concerned, even after reading this and learning more from other credible resources, then you certainly can choose organic foods or grass fed meat (they may be higher in price and have a bit different taste, but they are an option for you). Lastly, this also brings us to the very important point that I have mentioned many times: moderation! When you prepare your meals, be sure to plan in a variety of other whole foods withe your lean meats, such as fruits and veggies and whole grains to create a well-rounded, balanced healthy plate!
