The popularity of sushi in Japan may have been associated with Buddhism.
Buddhism was imported in the 6th century AD, and quickly became one of the major religions. One of the rules of Buddhism was to restrain from eating meat, and fish was not counted as such.
The emergence of American sweetened and carbonated beverages on the market has made kombucha or sour bread an unpopular relic.
Western corporations have succeeded, within fifty years, in completely displacing from our culture a beverage that was regularly consumed in central and eastern Europe for hundreds of years.
