Make restaurants list nutritional information in their menus

I'll give an example; A type 1 Diabetic who counts carbohydrates in the food they eat have to guess the carb content when the waiter brings the meal to the table by the size of the meal then administer insulin accordingly. If the carb content was listed on the menu this would help so much, as guessing the carb content could lead to injecting too much insulin thus the person suffers a hypo where the glucose levels drop and can be dangerous and can hospitalise that person
