I would say add emphasis on what not to eat. Don't eat junk food. our guts don't work properly and we want them to do as little work as possible. For example, bodybuilders don't eat any candy bars when they're getting ready for competition. It makes sense a UCr would take the same care of there body while flaring. It's hard but well worth it. If a bodybuilder can have such strong will power just to look better, it should be even easier for us b/c we are doing it for our own health and wellbeing.
Find out what foods your body digest easier and makes those your staple foods. Like for me I steam brocolli and carrots almost every day b/c it's easy, fast, packed with vitamins and they don't cause me any problems even when I'm flaring.
