Black Bean, Reduced Risk and Treatment of Colitis

Black bean with abundant chemical constituents and fiber may be considered as functional foods for the prevention and treatment of colitis, a renowned institute indicated.

Colitis is a medical condition of inflammation of the inner lining of the colon.

Black bean, a small roughly ovoid legume with glossy black shells, genus Phaseolus, belongings to the family Fabaceae can be bought in most grocery stores all around the year in dried and canned forms. It is believed that black bean was first domesticated growth in South America.

According to the joint study led by the University of Guelph, in vivo, cooked whole-bean flours, with differing phenolic compound levels and profiles, showing a completed inhibition of colitis in a mouse model.


In C57BL/6 mice fed a 20 % navy bean or black bean flour-containing diet or an isoenergetic basal diet (BD) for 2 weeks before the induction of experimental colitis via 7 d dextran sodium sulphate (DSS, 2 % (w/v) in the drinking water) exposure, coincidentally, both groups exerted similarly a beneficial and adverse effects in induced locally and systemically while aggravating colonic mucosal damage with unknown identity and systemic inflammation.

In the bean treatment group, the efficacy in ameliorated colitis may be a result of the inhibition of pro-inflammatory expressions, such as colonic inflammatory cytokines (IL-6, IL-9, IFN-γ, and IL-17A) and increased anti-inflammatory IL-10.



In mice with colon inflammation triggered by high-fat diet (HD)-induced obesity, injection of black bean expressed a significantly decreased the concentrations of lipid and various circulating proinflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 in mice with HD-induced obesity, in attenuated change associated to colon inflammation.

Furthermore, mice treated with black bean also improved antioxidant status in reduced progression
of reactive oxygen species (ROS) in the induction of oxidative stress.

Dr. Yook JS, the lead researchers said, "BAB ameliorates HD-induced disorders such as obesity and colitis by improving mucosal barrier protection and reducing endotoxemia, as well as by inactivating NF-κB to decrease the production of proinflammatory cytokines".

Taken together, the black bean may be considered as a functional diet in reduced risk of colitis in high-risk healthy subjects and treatment of patients with colitis with little or no adverse effects.
