I agree about the wheat/gluten. I tried my best to be on a plant based diet but found myself so hungry many times so I'd end up giving into organic wheat bread. I'm still working on it and have high hopes of accomplishing a much better diet. I want to stick mostly to juicing, smoothies and nuts to replace the bread/tortilla cravings.
It would be strange for me to be allergic to acidic fruits after eating them my whole life. I can relate to what you say about your throat. I've struggled with what feels like mucous in my throat, not sure if it's related to spicy foods.
Thank you for sharing this. I hope everything goes well for you and you find a solution soon.
