What is gluton ? I have houseguests that will be coming and have learned that one person is following a gluton free diet. Do you know if there are things that I need to have on hand , so that I have some things / proper food / preparation procedure on hand ? Is there a gluten free store ? my grocery stores are international have a wide range. i can find sugar free / diabetic or fat free products … but i do not see labels / aisles for gluten free. i am not even sure if my regular bottled waters / soft drink selection will be okay. I would like to have some beverage and snack choices. I am not sure of where to plan dinners out ? restaurants that would have menus / options to accomodate this special dietary need. Is there a website / or reference you know that explains what sort of a diet this is ? I did not get the impression that this is like a low call kind of a diet / that this person needs to have this or they will become sick.
