Does Coffee Have A Cross Reactivity With Gluten? Is It Safe On A Gluten Free Diet?

Where does this idea come from? How did it start? Is drinking coffee safe on a gluten free diet?

In short summary, there are no peer reviewed, published research studies that I have seen, to this date, that scientifically show a connection between gluten and coffee. What a lot of people on the internet are referencing is what their blood works suggests MAY play a problem.

Here’s how it works. If you do your blood work and you're found to have a gluten intolerance, you’ll receive a list of foods that the SPECIFIC lab has found to cross-reactive, or make worse, with gluten.

It’s the labs own internal research. Coffee frequently seems to cross react with gluten. There’s nothing that explain that connection. We know this with peanut allergies. If you have a peanut allergy you are likely to respond bad to legumes as well.

Is it a chicken and a egg thing? That is, does coffee cause a terrible reaction if you have leaky gut syndrome at first? Maybe, coffee does cross react with gluten but is it a secondary response?

Advice For Crossfit, Physique & Performance Athletes

While I’ll often have different recommendations based on different goals, the coffee-gluten cross reactivity relationship is the same as it would be for dairy or gluten in general. Remove coffee for 30 days and see what happens. Does coffee make you feel terribly right now with it in your daily diet?

If so, remove it. If you feel fine drinking a few cups of coffee per day, either lower your intake or remove it completely. One thing to factor is the source of coffee. I NEVER drink the same type of coffee beans for two days in a row. I enjoy coffee so much that I own about 6-8 different sources of coffee at one time.  Different sources of coffee likely all have different interactions with gluten.
