People suffering from sensitivity to Gluten have to plan their tours well.
Israel has a relatively high awareness to celiac, but it is still far from being known in all food places.
Best if you download and print this file in Hebrew, which you can present at food places in Israel.
I have gained some family experience in this field, and so can set a tour of Israel for celiac cases.
I have also conducted a thorough survey of places where people with Celiac dissorder can eat.
This list can be seen here.
