A friend has recently been diagnosed with celiac disease. This is where individuals develop intolerance to gluten, present in foods such as wheat, rye and barley. This will impact a number of halachic issues. Given the widespread prevalence of celiac disease I was surprised to find that there are few organised resources.
I am looking for a guide, or list, or reference links that are relevant for all issues that affect a person after being diagnosed with celiac disease.
For example: what to do if there is no suitable bread available on shabbat (lechem mishneh), what to do on pesach, etc.
