In a nutshell, the theory behind the Specific Carbohydrate Diet is that you avoid certain types of carbs that an impaired digestive tract is unable to properly breakdown and absorb. Carb intake is limited to simple sugars - found in honey, fruits and some vegetables - that require minimal digestive processing, are fully absorbed, and leave nothing behind to feed the bad gut bugs. This, coupled with probiotic supplementation, encourages the return of a healthy gut ecology. Also, because the foods are easier to digest, folks with IBD are able to better absorb nutrients.
If you find the SCD to be too restrictive, there are less restrictive diets for UC in Listen to Your Gut and The New Eating Right for a Bad Gut. Keep in mind that going on the SCD isn't a life sentence. Once digestion is radically improved, the gut healed and remission achieved, you're able to begin experimenting adding "forbidden" foods back into the diet.
