The 'pure' food approach quickly became boring and depressing for Martha. Especially most seemingly "pure" foods in restaurants are spoiled with vinegar food starch or other fillers. It's difficult to enjoy eating when your diet is limited to a few items.
Eating out at that time was practically impossible. We were already having enough troubles with the disease now we have to start interrogating restaurants wait staff about every ingredient in their menu items. When we did get a server that was not perturbed by all of the questions we didn't know all of the hidden ingredients to look for anyway. Some trips were successful others were less than.
