A safe food is anything that an Autistic person can eat when they are experiencing a sensory issue flare up. These foods will usually have a person's preferred textures and flavors. I've seen folks on other threads say things like "Bread and Butter" or a PB&J - usually things like that.

I think most people have "safe" foods, but don't realize it. Example - Chicken Noodle soup is still popular with folks who come down with a cold even if they never get sensory flare ups.

So I suppose the question for those who aren't sensitive to sensory information (like myself), it's - "What do you eat when you feel sick and don't want to eat anything?"

For me it's still a broad range of things. Sometimes it's Japanese Curry and Rice, other times its Indian Sambar (Reeeaaaally clears the sinuses).

I do tend to steer clear of oily dishes like Szechuan Eggplant (and a lot of other Ameri-Chinese dishes as well) when I'm feeling sick or sensitive, though.
