Gluten Intolerance and Grain Fed Meat

Do you ever wonder about the connection between gluten intolerance and grain fed meat? You’re not alone. We received a reader question regarding how meat from livestock that are fed grain affects people who have a gluten allergy. We ran the question by Dr. Ruth MacDonald, Chair and Professor of the Department of Food Science and Human Nutrition at Iowa State University.

Are people with Celiac disease (a gluten intolerance) at risk when they consume grain-fed meat?

Dr. MacDonald:

The simple answer is no. The animal converts food proteins into animal proteins by breaking down their structure during digestion (amino acids are separated and then repackaged during metabolism). Therefore, the meat will never contain any consumed proteins in their intact form. Meat, regardless of what the animal is fed, will not contain any gluten. The only way gluten could be in the meat is if the meat has been processed using fillers or if breading or some other type of preparation is done that adds a product containing gluten. But meat, by itself, is always gluten-free.

What is Celiac disease?

People with gluten intolerance are at risk of suffering damage to their intestines by eating foods containing wheat, rye, or barley. It is a genetic disorder that affects at least 1 in 133 Americans. Classic symptoms are diarrhea, weight loss, and malnutrition. It has been found mostly among people of European (especially Northern European) descent, but recent studies show it also affects Hispanic, Black and Asian populations.

    Celiac disease is not a gluten intolerance. Two totally different things. Someone with intolerance , the gluten may make them uncomfortable and in pain, but it will not damage their intestine. Someone with celiac, if they eat gluten it damages their intestine. Even 1 / 64 of a teaspoon… Every trace hurts us and it adds up.

      You need to understand the science. There are no whole proteins left. Just short chains of amino acids. Those will not affect you. It needs to be folded into the of its protein to affect people with Celiac.

        Yes, Lmurray is correct, mostly. The protein causing the immune response is gliadin, which is contained in gluten, so Clare Davis is almost correct, except for her attitude, which is way off. Suffer from celiac for a bit Clare before you go giving attude.

          I am a chef who regularly prepares food for people who have celiac disease, and they eat grass and grain fed beef all the time. Clare Davis is correct, and the only attitude I see here is from lmurray and trash80. Understanding the basic science involved is good, knee jerk emotions are not in anyones best interest.

      While there are more and less severe sensitivities to gluten, yes, celiac disease is an intolerance to gluten…
