Finding a GF probiotic

What is the best gluten-free probiotic to take? I was diagnosed this last February and honestly don’t know how many live bacteria I should be using on a daily basis.

Can coffee cause stomach issues?

My mother has celiac disease and is strictly on a gluten-free diet, yet she still has some stomach issues. This week I started reading about different people and articles saying that coffee could be causing that, as some coffee’s might be cross-contaminated with gluten. Is that true? I can’t find any scientific articles to test this theory out, but what I do find is many people online who claim switching over from processed coffee grounds to coffee beans has significantly helped them. I know coffee itself is gluten free but is there any truth to this?

Is tea gluten-free?

I only get very mild symptoms from ingesting gluten despite being clinically diagnosed with celiac disease. How strict should I be with my diet? Cross-contamination doesn’t usually bother me symptom-wise, but am I harming my body internally by not avoiding it more consciously?

Understanding gluten levels

I work for a frozen pizza manufacturing company. We currently process gluten-free pizzas using crusts sourced from approved suppliers. We understand the gluten level limits specified under FDA (<20 ppm) and our current gluten-free certification (<10 ppm). As we look to expand our gluten-free production capabilities. Are there resources or studies available that show statistical data on gluten levels to consider for most severe cases (e.g. 20 ppm versus 10 ppm or 5 ppm)?
