Gluten Content Test: McDonald’s Brewed Ice Tea


As a Celiac, I don’t eat food from McDonalds.  That ship has sailed.  I’m not sure where it went, but it’s gone.

I do however still enjoy their brewed ice tea.  Of course, this is a restaurant prepared item, so it’s going to vary on a location by location and batch by batch basis.

I performed a GlutenTox test at the 5 PPM (parts per million sensitivity).  I chose the more stringent option (GlutenTox allows you to choose between 5 and 20 PPM) because I thought… why in the world would this have any gluten, at all, in it.  Note that this test was completed with the unsweetened version, not McDonald’s Sweet Tea.


The test stick has two lines, the one on the left is the blue control line and should always become visible.  There is another possible line just to the right of that, that one is red.  That becomes visible if gluten is detected at the selected concentration.  As you can see in this photo only the control line is visible.  According to this result the sample I tested has a lower than 5 PPM gluten content.  Yay!

Each GlutenTox test comes with single use pipettes, extract solution, dilution solution, sample scoop and a test stick.  The testing process is relatively simple and the instructions are clearly written.  This test gives you some flexibility as you have the choice between testing at 20 PPM (parts per million) or 5 PPM.  Under 20 PPM allows manufacturers to label certain foods as gluten free.
