Scientists have discovered that eating a traditional Japanese pickle could have “protective effects” in preventing people from catching the flu.
Human trials have been started after a study in mice showed the bacterium in suguki, a pickled turnip dish popular in Japan, reduced the likelihood the animals would contract illness.
According to the findings, which have been published in the journal Letters in Applied Microbiology, the Lactobacillus brevis bacteria led to increased production of disease-fighting antibodies – including flu-specific ones.
The impact in mice was strong enough to prevent infection from the H1N1 flu strain.
Researchers said a new study was now under way, in which they are giving people a probiotic drink containing the same KB290 strain of the bacterium found in suguki.
Study author Naoko Waki, from the Japanese food company Kagome, said: “Our results show that when a particular strain of Lactobacillus brevis is eaten by mice, it has protective effects against influenza virus infection.”
