Jane- I eat lots of veggies of any kind<raw/streamed/sauteed>, blueberry-anything so long as no added sugar, apples, pears, apricots once in a while, watermelon. Avocadoes. Mushrooms. Legumes <not peanuts - possible peanut allergy> Also sustainable fish - usually sardines/anchovies or wild salmon, lox, gefilte fish - but don't eat fish often due to cost - some lean poultry, local or "organic-contimuum" eggs and also in-a-carton egg whites, almond, cashews, gluten free oats<try to usually get those, that is>, buckwheat cereal, quinoa, flax, brown rice on occasion, no-added-sugar applesauce, almond, cashew or sunflower seed butters. Herbal tea and carob; gluten free pancakes. Usually it's almond butter from the health food store. I love super dark chocolate but haven't had any for some time. Almond or coconut yogurt. I also drink a coffee substitute drink that comes in packets like tea, is gluten-free, made from chicory and carob and some other things - non acidic, no caffeine.
I avoid: red meat/pork/lamb, commercial bread and sweets, hydrogenated oils and MSG, and anything acidic, which means no coffee, tomatoes, citrus, no vinegars <so commercial salad dressings or other condiments>. I have dairy allergy <for years and years>, and started eating plant-based and shopping at health food store when I was in high school. Got a health food co-op membership from my hub as a gift maybe the second year we were married. Since inception of IC-like <bladder inflammation> symptoms last Summer I quit coffee "cold-turkey" and have also not had the acidic things mentioned, or chocolate or caffeinated beverages since that time. I never liked soda and we didn't have it hardly in my house when I was a kid. We had instant tea and my folks drank coffee or water usually.
