Correlation coefficient between increase in new cases of inflammatory bowel disease and food groups, nutrients, or energy.

Data from 1965 to 2000 were used. Foods, nutrients, or energy with a p value less than 0.0001 are shown in this figure, except for dietary fiber for ulcerative colitis (p < 0.001) (Table 2). The white column shows ulcerative colitis, and the black column shows Crohn’s disease.
