Yanjing natto is made from ordinary soybean and fermented by Bacillus natto. It has the functions of thrombolysis, softening blood vessels, resisting bacteria and improving immunity, which can help improve the problem of "three highs" in Chinese people.
However, Yanjing natto is only a common imported food. After entering the domestic market, it was exaggerated by many unscrupulous merchants and publicized to middle-aged and elderly people, taking advantage of the decline in judgment ability of the elderly and paying attention to health. So everyone should keep their eyes open and don't be credulous.
