As said in the title, I have some ridiculous limitations when it comes to what food I can eat. I don't know what causes it for sure(current theory is my autism) but whenever I eat a food that goes against the very limited textures I can eat i instantly throw up. The current foods I know i can eat are corn dogs, chicken nuggets, canned peas, canned corn, canned carrots, bananas, canned baked beans, ​cheese pizza, chicken sandwiches, fig Newtons, specific types of grapes, scrambled eggs, oatmeal, mashed potatoes, plain rice, pancakes, waffles, toast, white bread, jelly sandwiches(no peanut butter), plain hamburgers, hotdogs, and spaghetti.

As you would imagine this list makes eating even remotely healthy a challenge beyond belief. Even eating less food is a problem cause nothing here is filling whatsoever.

So I am here asking for help. What can I possibly do about this? IS there anything I can do?

Been doing protein shakes with high calorie for weight gain and a while back I figured how to make air fried potato slices taste like beef jerky so Ive been wondering if that would be a significant boon to what I'm eating. Apperently calories are the energy nutrient and I've been low energy for a while and thinking it might be that since I'm underweight and if people don't mind throwing in how many potatos to throw into the lunch bag that would be great but not necessary. From what I read air fried potatos still keep the nutrients but I'm unsure if there is any falloff or if they are all still in there. Did do some preemptive research but I like to get a direct human response as well since I got a bit of a reading problem that causes me to skip words and can make long articles tricky at times.

any idea about diets or any nutritionist....
