Bonus statistic: Approximately 30,000 new IBD cases are diagnosed each year in the U.S.

Eating SCD 
I think the Harvard School Of Medicine is on the right track, but a little behine. Research that crohns and candida albicans have a relationship. Many people who have been diagnosed with crohns disease have gotten remission by using and anti-yeast diet and or anti-fungal drugs. Many so called autoimmune diseases have been overcome using these methods. Some scientist and doctors believe there is a relationship between yeast infection/candida albicans and cancer.
