Healthy Food Navy Bean Promotes the Expression of Metabolite Markers that Improve Colon Health

By Kyle J. Norton

Metabolite markers are the reaction of the metabolites that respond sensitively to phytochemical exposure.

Phytochemicals are plant-based natural components that form an important part in the human diet and animal feed. Synthetic phytochemicals are also commonly found in dietary supplements and pharmacological agents.

Phytochemicals are chemical compound produced by the plants to protect them against predators such as insects and bacteria and fungi. Some phytochemicals are also used in traditional medicine to combat diseases.

According to Prof. Chi Chen in the investigation of the metabolite markers of phytochemicals wrote, "the bidirectional interactions between phytochemicals and the metabolic system, such as the disposition of phytochemicals, the regulation of nutrient, antioxidant, and microbial metabolism, and overdose-induced toxicities".

In other words, phytochemicals including bioactive phytochemical play an essential role in regulating the metabolic system through many metabolic pathways.

Believe it or not, metabolic effects have a strong impact on phytochemicals on the digestion, absorption, distribution, and metabolism of nutrients and antioxidants.

On the digestive system, bioactive phytochemicals play an essential role in the human diet as a valuable source of many bioactive components: phenolic compounds, vitamins or bioactive peptides.

On chronic diseases, consumption of total phytochemical intake has been found to reduce the risk of cardiovascular disease, cancer, and neurodegenerative diseases.

On the metabolism of nutrients,  gene-phytochemical interactions are individual differences depending on the individual genetic proposition, including the capacity to influence disease risk via several complementary and overlapping mechanisms.

More precisely, a person genetic variation in pathways has a strong effect on absorption, metabolism, and distribution of phytochemicals that expose at the tissue level or alter the biological response.

On antioxidant perspective, although phytochemicals and antioxidants are different, phytochemical antioxidants capacity demonstrated potential effects on oxidative status, that decrease the risk proteins, lipids, and cellular damage.

Collectively, by looking at the forms of metabolite markers, the tested assays after exposing to phytochemicals, researchers may know the inaction of the phytochemical and metabolic system.

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.

With an aim to find a natural compound for the promotion of gut health, researchers examined investigated metabolite markers of dry bean consumption in parallel human and mouse studies.

The study included 46 men who received dry bean enriched diet (250 g/day) for  4-weeks and 12 mice that received a standardized diet containing either 0 or 10% navy bean ethanol extract for 6 weeks.

According to the self-reported compared to the baseline, serum pipecolic acid (PA) and S-methyl cysteine (SMC) were elevated after dry bean consumption in human and mouse studies.

In other words, serum levels of pipecolic acid and S-methyl cysteine are metabolite markers that are useful to measure the amount of dry and navy bean consumption.

More precisely, according to the unpaired t-tests, a navy bean extract-enriched diet altered 26 metabolites (9% of analyzed metabolites) at P < 0.05 and 7 metabolites (2.4%) at q < 0.05 using unpaired t-tests; the most significant being PA, SMC, and NAO (all q < 0.003).

Furthermore, identified the biomarkers of dry (navy) bean intake may improve the understanding of the effect of navy bean in reducing the risk of colorectal cancer.

In intestinal microbial metabolism, the conversion of lysine to pipecolic acid (PA) may confer chemopreventive benefits for the human host because PA is a precursor of microbial compounds with anti-inflammatory property.

Taken altogether, the dry beans including navy bean may be considered a remedy for the improvement of colon health, through its metabolite markers,  pending to the confirmation of the larger sample size and multicenter human study.
