How many grams is there in one slice of wheat bread?

[Jack Common]

Hello!

I'm doing a gluten challenge now. I don't know how much bread to eat. There are 4-6 slices of bread a day suggested in most articles. But one slice of bread can be 25 grams or 40 grams. So when it's 25, six slices are just 150 grams. When it's 40 grams, six slices are 240 grams. The difference is huge in my opinion.

Can someone recommend the dosage?

Here is more info about how to do a gluten challenge for a celiac disease blood panel, or for an endoscopy:

"...in order to properly diagnose celiac disease based on serology and duodenal histology, doctors need patients to be on gluten-containing diets, even if they are causing symptoms, and this is called a "gluten challenge."

• Eat gluten prior to celiac disease blood tests: The amount and length of time can vary, but is somewhere between 2 slices of wheat bread daily for 6-8 weeks and 1/2 slice of wheat bread or 1 wheat cracker for 12 weeks 12 weeks;
• Eat gluten prior to the endoscopic biopsy procedure: 2 slices of wheat bread daily for at least 2 weeks;

and this recent study recommends 4-6 slices of wheat bread per day:

Thank you for your answer.

Well, I'm going to eat at least 5 slices a day, each of them is 35 grams. I think I'll do blood tests again after four weeks. If the results are negative or not clear, I'll continue the challenge and repeat blood tests again after another four weeks.

In case your tests turn out negative you may still want to try a gluten-free diet. Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS.

If I'm not mistaken, you need to count by the grams of GLUTEN, not the gram weight of the bread.  So, instead of counting each slice of bread as 35 grams, it would be counted as 2 grams, so that's why the recommendation is 5 slices a day = 10 grams.  One of the moderators can correct me if I'm wrong on that!
