Challenging Conventional Wisdom

One of the jobs of UF/IFAS scientists is to challenge conventional wisdom. You don’t want to bet the ranch on something that only seems true. Facts, empirical evidence and data are a more solid foundation for the truth you need to make decisions about the herd.

At the Florida Cattlemen’s Association convention this summer, I talked a little bit at the research and education committee about the importance of challenging conventional wisdom. For two reasons, I believe it’s one of the greatest services that the UF/IFAS provides its stakeholders.

First, challenging conventional wisdom can reveal new insights about how to run a ranch and even correct practices that impede efficiency and productivity. In addition, a scientific challenge to conventional wisdom can debunk customers’ falsely held beliefs about what producers do.

Here are three examples of how UF/IFAS agricultural scientists are challenging public perception that passes for conventional wisdom about the cattle industry.

It’s What’s for Dinner

The conventional wisdom around how eating red meat might increase your cardiovascular disease risk has been a matter of debate. Wendy Dahl of the UF/IFAS Food Science and Human Nutrition Department didn’t accept one recently proposed explanation. She found in a study of older women that a well-balanced, high-protein diet with beef for dinner did not increase the metabolite associated with increased cardiovascular disease risk. More research is needed, but her research demonstrates that if we just accept conventional wisdom, we risk missing out on deeper truths.

Resistance to Conventional Wisdom

The conventional wisdom is that cattlemen feeding their animals too many antibiotics is causing all our beef-related anti-microbial resistance problems. Not so fast, says KC Jeong, an animal sciences professor in the UF Emerging Pathogens Institute.

Jeong continues to do research that identifies anti-microbial resistance even in herds where barely any anti-biotics are used. He investigates how resistance can be a product of the environment, like in the soil and forage, and that management techniques can reduce the prevalence of anti-microbial resistance.


Sustainable Source

The conventional wisdom is that animal-source foods represent a sustainability problem. Geoff Dahl, no relation to Wendy, and Gbola Adesogan, were honored at our research awards in May for their work in reframing this paradigm.

Negative impacts of animal-source foods on planetary heath are overstated, say Dahl and Adesogan. Animal-source foods are a sustainability solution, as they help meet U.N. sustainability goals. Dahl and Adesogan document in their work in Africa and Asia that the introduction of small amounts of animal-source protein into the diets of infants around the world substantially reduces malnutrition that often leads to stunting or worse.

I don’t want to see kids starve because of conventional wisdom that’s not solidly grounded in evidence. I don’t want consumers blaming producers alone for anti-microbial resistance if there are many sources and causes. I don’t even want producers to rely on UF/IFAS science if it’s decades old and needs to be validated under today’s conditions.

That’s why we continually strive to update our findings. I appreciate the support for UF/IFAS science that we get from the FCA research and education committee and its chair, Lint Jerrells. It strengthens our resolve to find truth, even when that search challenges what we believe to be the truth.
