Black Bean, The Best Functional Food for Hypertension

Adding a portion of cooked black beans in your diet may substantially. reduce risk and enhanced treatment of hypertension, a respectable university study suggested.

Hypertension is a medical syndrome characterized by abnormally high blood pressure, affecting high portions of the population in the world, according to the statistic.



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 Illinois at Urbana-Champaign, Mexican black bean isolated proteins peptidase-IV (DPP-IV), after pepsin/pancreatin digestion, showed a significant effect in reduced hypertension at dose with IC50 = 0.03-0.87 mg and dry weight and inhibited α-glucosidase, a protein related to early onset of diabetes, ranged from 36.3 to 50.1% mg-1 DW.


The efficacy of the anti-hypertension of the black bean is attributed to the elevation of antioxidant capacity fighting against the forming of reactive oxygen species (ROS), Dr. Mojica L, the lead author insisted.



In an article published at the Research Journal of Pharmaceutical, Biological and Chemical Sciences,
black bean crude extract decreased both systolic as well as diastolic BP in a dose-dependent manner (1-100 mg/kg).

The article also indicated that the fall of both pressures may be due to the presence of phytochemicals saponin fraction and mediagenic acid glucoside in the crude extract.


Furthermore, azuki bean (Vigna angularis) seed coats (ABSC) with different color, containing high amount of polyphenols attenuated vascular oxidative stress and inflammation associated with hypertension in the experiment of hypertensive rats (SHR) and control normotensive Wistar-Kyoto (WKY) rats.

More importantly, treated mice with azuki bean (Vigna angularis) seed coats (ABSC), suppressed the elevation of SBP throughout the treatment period of 8 weeks, by decreasing of NADPH oxidase inactivated free radical expression and increasing antibody p47phox and Nox4 against radical formation through mRNA expression.

Dr. Mukai Y, the lead researcher said, " polyphenol-containing ABSC could attenuate vascular oxidative stress and inflammation during the progression of hypertension, and this may lead to an improvement in hypertension".

The findings suggested that black bean with various chemical constituents may be considered as a functional and integrated food for reduced hypertensive risk and treatment of high blood pressure.
