Bacillus subtilis var.
Research study suggests that natto, a Japanese fermented soybean dish, might extend lifespan and enhance tension resistance due to its Bacillus subtilis var. natto bacteria content. If these results are transferable, the research study indicates possible human health and longevity benefits.
Taking in natto could possibly aid in relieving stress.
Health is wealth as the stating goes and now new research study recommends that the key to a much healthier, less stressed out society may lie within easily accessible and inexpensive food products.
A prime example of such a food is the Japanese dish called natto. Most of the natto consumed in Japan is made from the Miyagino stress.
A research study group led by Professor Eriko Kage-Nakadai at the Graduate School of Human Life and Ecology, Osaka Metropolitan University, examined the effects of Bacillus subtilis var. natto consumption on the life expectancy of the host using Caenorhabditis elegans worms.

The researchers found that Caenorhabditis elegans fed Bacillus subtilis var. natto had a considerably longer life-span than those fed the standard diet plan, and more elucidated that the p38 MAPK pathway and insulin/IGF -1- like signaling path, which are known to be associated with natural resistance and life-span, were included in the lifespan-enhancing effects of Bacillus subtilis var. natto. They likewise examined stress tolerance, which has been revealed to have a correlation with longevity, and discovered that resistance to UV light and oxidative stress is boosted.
Teacher Nakadai concluded, “For the very first time, we were able to show the possibility of lifespan-extending effects of Caenorhabditis elegans through the consumption of Bacillus subtilis var. natto. We hope that future experiments on mammals and epidemiological studies will assist to recognize a healthy and longer-living society if we can apply this research to human beings.”
