Maybe try a fermented food like non pasteurized sauerkraut. You can make your own easily and craft it to your taste preferences. Lactobacillus is not a default resident in the gut microbiome, so has to be replenished regularly. It is a powerful ally against pathogenic bacteria in the gut by directly competing with and literally poisoning the populations of bacterial overgrowth. Your gut microbiome has an enormous effect on your body in general, but your immune system in particular. It’s likely your allergies were created by living in an extremely clean environment as a child, and those pathways on the mast cells can’t be easily be reprogrammed, however building a healthy body microbiome will help. Throw away your antibacterial soap and hand sanitizer, rinse your hands with water, maybe a little coconut oil after the rinse. The solution to pollution is dilution, and the concentration is the difference between an informed immune system and infection followed by disease. Regarding fruit, it’s mostly just sugar. I’d cut that and add a few cruciferous vegetables. 🥦
