My appendix had to come out when I was studying in Costa Rica, eating lots of tropical fruits and veggies, not much meat. I had been there about a month. I was soooo sick of papaya at every meal! After a three day fast in the hospital, the first food they gave me was papaya for breakfast, followed by papaya juice with lunch!
My daughter's appendix ruptured when she was ten. We were living on a farm, complete with organically grown veggies, chickens, dairy goats, etc. We had been living there for a couple of years. What was scary about her experience was that I didn't take her to the doctor because I thought she just had stomache flu. She nearly died from peritonitis.
