INS and inflammatory bowel disease: Within the IBD group, a higher intake of added sugar and processed meat and a higher serum insulin level was associated with lower stool microbial alpha diversity (processed meat intake and Shannon’s diversity: r = −0.43, adj-p = 0.02; added sugar and Shannon’s diversity: r = −0.39, adj-p = 0.03; insulin and Shannon’s diversity: r = −0.45, adj-p = 0.02).
