Allergic to literally everything

A year ago in Oct I found out for sure that I am in fact allergic to nearly everything. What isn’t shown on here is my serious allergy to vegetables that aren’t sauted in a meal. I am also very allergic to fruits, both fruits and vegetables make my saliva thick, makes it very difficult to swallow, I turn red, get really hot my throat starts itching etc.

I am pregnant with my 3 full term this far(7 year old, 4 years and 12 weeks pregnant with the 3rd), miscarried 3 babies years ago.

This pregnancy I really want to be able to eat fruits. Are there any other ways to get the nutrients from fruits or vegetables in my system without eating them fresh..

Please give any and all ideas, has anyone else experienced this also? This all started when I was 6 1/2 months pregnant with my 7 year old
