Healthy Legume, Navy Bean Promotes the Gut Health

By Kyle J. Norton

The colon formed part of the digestive system is also called the large intestine which plays a critical role in removing water, salt, and forming a stool through its muscles lines.

There are over 100 trillion live in the colon that maintains a healthy balance with the body.

In a normal or healthy individual,  gut microbiota besides protecting the host against pathogens that cause infectious disease, it also has strong  imparts in some specific function in the host, including
* Nutrient metabolism is a process that absorbs end products of food digestion such as monosaccharides, glucose from carbohydrates, monoacylglycerol and long-chain fatty acids from lipids, and small peptides and amino acids from protein.

* Xenobiotic metabolism is the action that protects the host against chemicals that affect normal metabolism.

* Drug metabolism is the process to alter chemical of a drug that may cause harm to the body

* Gut microbiota also has been found to protect gut mucosal barrier in preserving the ability to absorb nutrients.

Gut microbiota immunomodulatory activity reduced risk of disease associated with chronic inflammation of the digestive tract, such as bowel inflammatory disease.

However, there are several factors that may have strong impacts on gut microbiota. Dr. Sai Manasa Jandhyala, the lead scientist wrote, " (1) the mode of delivery (vaginal or cesarean); (2) diet during infancy (breast milk or formula feeds) and adulthood (vegan based or meat based); and (3) use of antibiotics or antibiotic like molecules that are derived from the environment or the gut commensal community. 

And "A major concern of antibiotic use is the long-term alteration of the normal healthy gut microbiota and horizontal transfer of resistance genes that could result in the reservoir of organisms with a multidrug-resistant gene pool".

The small, white navy bean, also called pea bean or haricot, popular in both dry and green forms, is very popular in Britain and the US, native to Peru. It is now grown and consumed across the world, due to their numerous health benefits.

On finding a natural compound for the improvement of colon health, researchers examined the effect of cooked navy bean (NB) or black bean (BB) flours on the colonic microenvironment in the gut.

The study included C57Bl/6 mice were fed diets supplemented with 20% cooked navy bean (NB) or black bean (BB) flours or an isocaloric basal diet control (BD) for 3 weeks.

According to the tested analysis
* Both NB and BB similarly altered the fecal microbiota community structure by increasing the abundance of carbohydrate fermenting bacteria such as Prevotella, S24-7, and Ruminococcus flavefaciens.

* Both beans also enhanced short-chain fatty acid (SCFA) production (microbial-derived carbohydrate fermentation products) by activating the colonic expression of the SCFA receptors GPR-41/-43/-109a associated with reduced colonic inflammation.

* Furthermore, parameters associated with the improvement of the colon health were also enhanced by the administration of black and navy beans, including the biomarkers of colon barrier integrity such as crypt height, mucus content, cell proliferation, and goblet cell number.

The results strongly suggested that navy bean improves colon health by increasing the expression of gut "good" microorganisms.

Based on the findings, researchers said, " Overall, NB and BB improved baseline colonic microenvironment function by altering the microbial community structure and activity and promoting colon barrier integrity and function; effects which may prove beneficial in attenuating gut-associated diseases".

Taken altogether, the cooked navy bean may be considered a remedy for the improvement of the colon health, pending to the confirmation of the larger sample size and multicenter human study.
