Gluten challenge food list for low carb/keto

[LondonJules1]

I have to do a gluten challenge before getting tested for celiac disease.  This will require me to eat about 10g of gluten every day for the next four weeks.  I have been very successful at keto (max 20g carbs per day) for the last 15 months which by eating low carb essentially eliminates gluten from the diet.  I'm okay with stalling with the weight loss, but am hoping not to gain too much weight.  Does anyone have suggestions for lower carb food items that contain gluten?

You can sprinkle vital wheat gluten on any food you like.

...The above....there are some companies that make low carb breads using the gluten protein  Sure to get you that gluten challenge done with 1-2 slices a day... https://www.amazon.com/ThinSlim-Foods-Calorie-Love-Taste/dp/B00HBFH2PI/

I am guessing by the screen name that LondonJules1 is in the UK so here are links for the same or similar items in the UK.

I can't find that same bread in the UK but I found this thread of diabetics in the UK so you should be able to get some ideas from that.

What about mock meat? Seitan? Do these contain gluten?

[Ennis-TX]

I think this varies by brand etc. Seitan is generally made up of the gluten proteins so I would venture to say yes. But mock meat is a broad term from what I can find and covers even gluten free fake meats like soy, mushroom, and jackfruit unless you are talking about a certain brand.

Just like checking ingredient list for no gluten ingredients you can look for ones with wheat gluten rather why on the list to see if it will work for a challenge food I would imagine.
