All of these comments support what I've experienced for years -- just about anything in a package is suspect for gluten no matter how much the label trumpets its gluten-free status. And that includes foods that are labeled "certified gluten-free." A while back I was especially disappointed with nuts.com products -- after I had a reaction. As a result, I've gone through several periods when my celiac symptoms (which include significant cognitive issues, nervous system problems and arteriosclerosis) have led me to eat nothing out of a package and have cooked everything from scratch. Even today, the only nuts I eat are those I buy in the shell, crack open myself and cook. I have had too many bad experiences with nuts that I didn't prepare this way. 

I think in the UAE you may have access to pistachios, cashews and coconut. All would be packed with calory and nutrient dense. Cashews especially, are both high in fat and higher in carbs than most other nuts.

Bananas are rich in fiber, potassium, magnesium, iron, phosphorus, and zinc and B vitamins.  One of the first successful treatments for Celiac Disease used banana as the main carbohdrate energy source. quick, easily digestible energy, easier on sensitive stomachs and offer more potassium, which can help replenish electrolytes lost through sweat.”   I clean and separate the banana from the bunch and store in the refrigerator.  The outside peel may turn color, even black, but the banana inside does not get overripe so they can last a long time.

I only intend to do the blood screen. I also fully intend to remove gluten from my diet whether the test is positive or negative.  I’d just like to know, even if it’s inconclusive, if Celiac might be the cause my life-long gastrointestinal distress. If the test is positive, I’ll assume that I probably have Celiac, like my sister. If it’s negative, I’ll assume that I may have a gluten intolerance/allergy — or not.  My quest will end there. My belly problems don’t render my life insufferable. My sister’s diagnosis (positive blood and biopsy) just made me curious whether I have Celiac, too. Either way, I’m done with gluten as soon as I give the blood sample on Wednesday 👍🏼
