Oranges may give you arthritic pain - lemons wont
  Every Christmas our kids' school had a fund-raiser of citrus: oranges and 
grapefruit. We'd get a lot and then eat a lot, before it spoiled. So every 
January I'd have awful arthritis symptoms, until I read this book and figured 
out what was happening. I can cook and eat tomato dishes, but more than one 
night will trigger arthritis pain. Now i can anticipate it's effect and take 
ASG before and after indulging. Helps a lot.
