Here is a link to our Newbie 101 thread that you might find useful.
I can only comment on those foods that I have in my home or have purchased.
1. Nutella is and it states it in the label.
2. Skippy PB is gluten-free (not stated, but ingrediants are).
3. Soy sauce. It should state it on the label as gluten free or do not eat it. Most soy sauce is NOT gluten free as it contains wheat.
4. Maple syrup is gluten-free if it is pure (only one ingrediant). Otherwise read the ingredients.
5. Fresh minced meat should be gluten-free if you prepared and cross contamination did not occur in your kitchen (e.g. Pot, cutting board, etc.). Not sure if this is a canned product.
Bottom line is that you have to read labels carefully. In the beginning it is best to eat fresh foo you prepared. The. Add in processed food as you learn to read labels and determine if you have other intolerances to foods other than gluten (very common for celiacs or NCGI).
In my brief research, I did not find any public papers indicating villi blunting for Losartan specifically. There was research and a law suit on olmesartan (other celiac.com members have pointed out). Dr. Hart may have been making clinical observations or has access to medical research that is not public (or free). He is/was located at the University of Chicago.
Are you still having GI symptoms despite the gluten free diet and your supplements?
If not, this BP drug may not be affecting you. I understand your concern, so you might talk with your doctor or pharmacist about an alternative drug or re-visit the need to take this drug. Make sure they know all the supplements you are taking in addition to other prescription drugs.
Talk also with your GI about your suspected or continued malabsorption issues. Have you had follow-up biopsies?
I understand your concern. I hope you find a solution that satisfies you and your doctor.
I did find a local store that carries the Canyon House brand and will give that a try. It can be tough as I live in a fairly rural area and we don't have a lot of the resources many of the more urban areas do. It is a 1 hour round trip just to get to the closest town with anything like a Trader Joe's or New Earth Grocery. One of out 2 health food stores in town even closed down a few years ago ands this town is full of Seventh Day Adventists that do a lot of shopping at health food stores. Most of my shopping will likely be done online at Amazon, but there is much more availability at even SaveMart and Safeway nowadays.
Often drugs that end in –artan are ARBs, and they work by blocking the angiotensin receptors. I’m not sure what the exact difference is between the two medications you mention, though. Have you called the manufacturer of losartan to see if any of the fillers contain gluten? It might be a good idea to know what those fillers are.
In my drug book “dyspepsia” and “gastritis” are mentioned as side effects, but they did not drill down to the specificity of villous blunting. I did some googling, and in addition to what Knitty found, I came across this:
Small Bowel Histopathologic Findings Suggestive of Celiac Disease in an Asymptomatic Patient Receiving Olmesartan
“Although Rubio-Tapia et al are careful to avoid claiming a proven causal relationship between olmesartan therapy and the observed spruelike enteropathy, the data are highly suggestive of more than just a coincidental association.
“They further suggest that a potential mechanism for the enteropathy could relate to inhibitory effects of angiotensin II receptor antagonists on transforming growth factor β action because transforming growth factor β is important in gut immune homeostasis.
“Although anecdotal, these observations lead to the hypothesis that olmesartan, and perhaps other angiotensin II receptor antagonists, could be a cause of intraepithelial lymphocytosis in architecturally preserved proximal small intestinal mucosa.”
(One of the patients in question was offered the opportunity to do a gluten-free diet, but he/she declined.)
So, it looks like you are definitely on to something, and if this turns out to be a “thing,” would probably warrant dissemination on a wider scale.
You didn't mention what your BP is with the medication or was without it, but please let your health care provider know if you do decide to discontinue your blood pressure medication. It's often recommended not to DQ suddenly, which can cause the BP to spike in some cases.
ETA: Just because a drug can cause a particular side effect does not mean it does in your case. I just thought I'd add that, but nevertheless totally and completely understand the cause of concern in any case.
