Is the carbon in water filters gluten-free?

This sounds so ridiculous, but I'm wondering if anyone knows about the gluten status of carbon water filters. I read that "activated carbon is carbon produced from carbonaceous source materials such as bamboo, coconut husk, willow peat, wood, coir, lignite, coal, and petroleum pitch." Is there anything else it could be made of? We're looking to install a under the sink system but most companies don't state what material the carbon is derived from.

Although I'm 95% sure its fine, I've heard of people with coconut allergies get reactions from water filters (such an awful scenario). I'm wanting to get some reassurance before buying and installing the whole thing!

The coconut is different.  If I remember it is still in its coconut fiber/huskform.  
 

I never worry about a water filter.  If they burn the heck out of something to make it into carbon- there isn’t any protein in there.

Thanks for the reassurance Kareng. That makes sense.

When I am in misery due to a celiac reaction, I try to figure out what is harming me.  So much so that I started to think about the binder for the charcoal filtration in my water system. Verdict: who knows!?  But here is some info I found on a website:

What is the best binder for charcoal briquettes?  Starch is the most common binder though it is usually expensive. It doesn't have to be an food grade. In general, about 4-8% of starch is needed to make the briquettes. Starch sources can be corn starch, wheat starch, maize flour, wheat flour, rice flour, cassava flour, potato starch, etc.

      What should I do with these test results?

      By trents · Posted

      I agree. Doesn't look like you have celiac disease. Your elevated DGP-IGG must be due to something else. And it was within normal at that after your gluten challenge so it is erratic and doesn't seem to be tied to gluten consumption.

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

      By Jack Common · Posted

      Hello! I want to share my situation. I had symptoms like some food intolerance, diarrhea, bloating, belching one year ago. I thought I could have celiac disease so I did the blood tests. The results were ambiguous for me so I saw the doctor and he said I needed to do tests to check whether I had any parasites as well. It turned out I had giardiasis. After treating it my symptoms didn't disappear immediately. And I decided to start a gluten free diet despite my doctor said I didn't have it. After some time symptoms disappeared but that time it wasn't unclear whether I'd had them because of eliminating gluten or that parasite. The symptoms for both are very similar. Giardiasis also damages the small intestine. The only way to check this was to start eating bread again as I thought. Now about my results.   These are my first test results (almost a year ago) when I had symptoms: The Tissue Transglutaminase IgA antibody - 0.5 U/ml (for the lab I did the tests 0.0 - 3.0 is normal) The Tissue Transglutaminase IgG antibody - 6.6 U/ml (for the lab I did the tests 0.0 - 3.0 is normal) Immunoglobulin A - 1.91 g/l (for the lab I did the tests 0.7 to 4 g/l is normal) IgA Endomysial antibody (EMA) - < 1:10 titer (for the lab I did the tests < 1:10 titer is normal) IgG Endomysial antibody (EMA) - < 1:10 titer (for the lab I did the tests < 1:10 titer is normal) Deamidated gliadin peptide IgA - 0.3 U/ml (for the lab I did the tests 0.0 - 6.0 is normal) Deamidated gliadin peptide IgG - 46.1 U/ml (for the lab I did the tests 0.0 - 6.0 is normal)   Then I didn't eat gluten for six months. Symptoms disappeared. And I started a gluten challenge. Before the challenge I did some tests. My results: The Tissue Transglutaminase IgG antibody - 0.5 U/ml (for the lab I did the tests < 20 U/ml is normal)) Deamidated gliadin peptide IgG - 28 U/ml (for the lab I did the tests < 20 U/ml is normal)   During the challenge I ate 6 slices of wheat bread. After the challenge my results are: The Tissue Transglutaminase IgA antibody - 2.0 U/ml (for the lab I did the tests < 20 U/ml is normal) The Tissue Transglutaminase IgG antibody - 2.0 U/ml (for the lab I did the tests < 20 U/ml is normal) Immunoglobulin A - 1.31 g/l (for the lab I did the tests 0.7 to 4 g/l is normal) Deamidated gliadin peptide IgA - 2.0 U/ml (for the lab I did the tests < 20 U/ml is normal) Deamidated gliadin peptide IgG - 2.13 U/ml (for the lab I did the tests < 20 U/ml is normal)   To be sure I continued consuming gluten. I ate a lot each day. Two months after I did the tests again. My results I got today are: The Tissue Transglutaminase IgA antibody - 0.7 U/ml (for the lab I did the tests < 20 U/ml is normal) Immunoglobulin A - 1.62 g/l (for the lab I did the tests 0.7 to 4 g/l is normal) Deamidated gliadin peptide IgG - 25.6 U/ml (for the lab I did the tests < 20 U/ml is normal)   Nowadays I didn't have any symptoms except tiredness but I think it's just work. I think it was this parasite because two years ago, for example, and before I didn't have these symptoms and I always ate gluten food. But I'm still not sure especially because the Deamidated gliadin peptide IgG results are sometimes high. What do you think? @Scott Adams

      My old results (almost a year ago) are: The Tissue Transglutaminase IgA antibody - 0.5 U/ml (for the lab I did the tests 0.0 - 3.0 is normal) The Tissue Transglutaminase IgG antibody - 6.6 U/ml (for the lab I did the tests 0.0 - 3.0 is normal) Immunoglobulin A - 1.91 g/l (for the lab I did the tests 0.7 to 4 g/l is normal) IgA Endomysial antibody (EMA) - < 1:10 titer (for the lab I did the tests < 1:10 titer is normal) IgG Endomysial antibody (EMA) - < 1:10 titer (for the lab I did the tests < 1:10 titer is normal) Deamidated gliadin peptide IgA - 0.3 U/ml (for the lab I did the tests 0.0 - 6.0 is normal) Deamidated gliadin peptide IgG - 46.1 U/ml (for the lab I did the tests 0.0 - 6.0 is normal)   Then I didn't eat gluten for six months and after I started a gluten challenge.

I'm not IgA deficient as you can see so I don't need to do this Deamidated gliadin peptide IgG test. But I do because it's sometimes not in the normal range. What do you think this time? I think I don't have celiac disease. But this test...

      Anyone else with very high HDL?

      By Wheatwacked · Posted

      @plumbago, I found a good PDF on cholesterol:  Unlocking the mysteries of VLDL: exploring its production, intracellular trafficking, and metabolism as therapeutic targets I just started it, but it may have answers for us, with whacky cholesterol.  The pharmaceuticals don't seem to be interested in anything but statins.   "The nicotine in tobacco causes a decrease in the HDL cholesterol level. " Maybe you should start smoking? 🤪 I have high LDL and low HDL.  It is genetic mutations in the LDLR, APOB, PCSK9, or LDLRAP1 genes. My whole family is on statins for Familial Hyperliperdemia except me.  December I had ultrasound and cat scan for Carotid Artery blockage and both sides are above 85% blockage.  I started on Atorvastatin and that made me weaker than ever, even with CoQ10.  I asked for and got prescription for 2000 mg/day Nicotinic Acid B3 and in the 3 weeks my numbers changed. I am feeling realy good lately.  Stronger and more flexible.  Sleeping better.  Getting roto router (TCar) as soon as I get clearance from a cardiologist.  I expect that by my next blood panels in April to be even better. I am beginning to believe that like vitamin D where the RDA only accounts for preventing Rickets, the RDA for B3 is way underestimated.   From Oct 22 to Jan 17: A1c from 13.5 to 10.2 eGFR from 55 to 79 Triglyeride from 458 to 362 Total cholesterol from 245 to 264 HDL from 27 to 44 VLDL from 84 to 68 LDL from 134 to 154

      Anyone else with very high HDL?

      By plumbago · Posted

      I have taken thiamine on and off (just not at this exact moment), and I’m not sure it's made any difference. Yes, I almost always “fast” (12 hours NPO) for blood tests, as do a great many other Americans, so I tend to think that’s not it. All I can say is that the mystery continues. I could do some speculating here…well, heck, let me go ahead and speculate now: The lab ranges we all see on our reports are more or less the averages of Americans who have had those blood tests. Now, it’s up to you and me whether or not to think of the average American as healthy. I can make arguments both ways, more often than not, on the negative. My point here is that maybe the current range of HDL is somewhat skewed (ie, low), and maybe just maybe my super high (plus 100s) HDL results are not something to worry about; the range just needs updating. Why do I say this? Because pre-celiac disease diagnosis, my HDL values were in the normal range, but post celiac disease diagnosis, my HDL levels are way above average. See where I’m going? My trusty guidebook on celiac disease, Recognizing Celiac Disease by Cleo Libonati, RN, BSN, says that HDL increases after being on the gluten free diet. Or can increase, I guess. Then again, it could be something else. ¯\_(ツ)_/¯ In thinking of going to a cardiologist, I sort of fear that he/she will be dismissive of a link to celiac disease, treated celiac disease, and would not therefore be considering all possibilities. @trents I'm sorry you've been diligently working on your numbers to no effect. That must be frustrating. LDL is a world that is far better understood than HDL, so for you there's maybe less "mystery." Familial hypercholesterolemia is for sure something that can be tested. Outside of that, you're right, genetics can determine a general pattern.
