Health is wealth as the saying goes and new research now shows that it is possible to have a healthy, less stressed society through familiar and inexpensive foods. One such food might be the Japanese natto which is made from softened soybeans that have been boiled or steamed and fermented with a bacteria called Bacillus subtilis var. natto. Bacillus subtilis var. natto is found in soil, plants, animals, and the human stomach and intestines. Most of the natto consumed in Japan is made from the Miyagino strain.

A research 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 lifespan of the host using Caenorhabditis elegans worms.

The researchers found that Caenorhabditis elegans fed Bacillus subtilis var. natto had a significantly longer lifespan than those fed the standard diet, and further elucidated that the p38 MAPK pathway and insulin/IGF-1-like signaling pathway, which are known to be involved in innate immunity and lifespan, were involved in the lifespan-enhancing effects of Bacillus subtilis var. natto. They also examined stress tolerance, which has been shown to have a correlation with longevity, and found that resistance to UV light and oxidative stress is enhanced.
