20 ppm equals...?

So I was wondering, if a gluten-free food is supposed to be 20ppm or less, how much does that equal in a serving of the food? What if you eat several servings of the food, what would happen? I have been known to binge on cookies, and  to have 2 servings of pasta at a time (or more in a day.) Is this 20ppm safe for unlimited servings? Or am I understanding this incorrectly.

PS At first my dh was so sensitive I couldn't have any gluten-free substitute foods without starting to itch.

I think GFWD did a article on how much is 20ppm in relations to gram servings. Also you need to consider as 20ppm is the maximum allowed limit...you recall that issue I had with the "gluten free" hemp protein that lab tested at 16ppm? I was having 2-3 servings of that a day and took days to get symptoms, and oddly none of my violent ones showed. I have seen many cases where foods tested 5-10ppm....like most of the controversial cheerios tested or oat based gluten free foods....then again we have no way to test the 1-5ppm range as none show up on test........damn what I would not give for a Star Trek Food replicator where we can dictate the proteins in our foods.....like true gluten free meals.....>.< I still dream of forming a gluten free nation on a island.

Victoria - this is such a good question.  I say that, because I have been wondering it myself!

Over the summer my 'gastritis' may have been gastritis, but it may have also been my coeliac disease, as my autumn ttg figures were high.   There had been CC and I'd also been taking Floradix instead of Floravital.  But the only other thing that went through my mind was that I had also been eating a lot of gluten free substitutes - biscuits, bread etc.

Because it is winter (bad excuse) I've been eating a lot of these things recently.  If my ttg is still high/endoscopy shows damage at next testing I shall go down the whole food route more seriously.  I was meant to be doing Fasanos this January but my nutritionalist wanted me to wait to see if I needed to.

I think the answer to our question may be in this article, but as I think I have a touch of discalcula these numbers just whirl around in my head and make little sense to me!

If you eat 1 kilogram (2.2 pounds) of food that contains 20ppm (parts per million) of gluten, you would have eaten 20 milligrams (mg) of gluten.  Many,  but not all, people with celiac can tolerate that amount.  When FDA set 20ppm as the limit it was partly because it would be safe for most with celiac, and because at that time most analytical methds for gluten could not accurately measure values less than that.

thank you for the detailed reply! I will continue to indulge when necessary. I'll take one for the team.

      Vitamin D deficiency can contribute to rib pain. Chest pain stemming from the ribs ccould be costochondritis, which involves inflammation of the cartilage connecting the ribs to the breastbone. This pain can range from mild to severe, potentially mimicking heart attack symptoms, and is often worsened by breathing or movement. Other potential causes include muscle strain, rib fractures, or even referred pain from other conditions.  It will also help to chose vegetables low in omega 6.

      Great question! Even if some individuals with celiac disease don’t experience immediate villi damage from occasional cross-contamination, it’s still strongly recommended to maintain strict avoidance of gluten. The immune response triggered by gluten can vary between individuals, and even small amounts may cause systemic inflammation or other symptoms, even if intestinal damage isn’t immediately detectable. Additionally, repeated exposure—even at low levels—could lead to cumulative harm over time. Strict avoidance of cross-contamination remains the safest approach to prevent long-term complications and ensure overall health. Everyone’s sensitivity differs, so working with a healthcare provider to tailor precautions is ideal.

      You have one gene for Celiac.  You have a second autoimmune disease, Hashimoto's thyroiditis, which is frequently found at a higher rate with Celiac.  HLA genes carry autoimmune disease genes like Celiac and Hashimoto's and diabetes and others.   You have Celiac symptoms of reacting after gluten.  You said "I am however still suffering from the effects of the gluten challenge (food sensitivities, slight brain fog, weird stool, fatigue, swollen thyroid, bodyaches)."  And your anti-thyroid antibodies increase after gluten exposure.  While tTg IgA does not directly attack the thyroid, gluten exposure does trigger the  immune system to produce antibodies against the thyroid in genetically predisposed individuals.  You did not eat sufficient gluten (10 grams of gluten per day for two weeks minimum) to raise the autoimmune antibodies to the point they can be measured in the blood, so your blood tests may well be inaccurate.  You could choose to continue the gluten challenge of 10 grams a day for at least two weeks and get retested.   At the very least, you know that gluten is harmful to your thyroid, and because you are genetically predisposed to Celiac disease, a strict gluten free diet would be beneficial for your overall health.

      Thanks @Scott Adams! I guess my question now is: do the celiacs who can get away with regular contamination without villi damage as you mentioned have to be strict about cross-contamination ?
