Once I had been believing that "NATTO will work to prevent COVID19".
Because I thought NOTTO germ is strong enough to kill COVID-19 virus.
I was wrong. Virus is different from germs. Virus does not live, die, eat nor breed. We can not kill virus but just destroy them.
However, NATTO protects you from COVID-19 anyway. Refer to the recent
Report by Guardian. It refers to the vitamin K included in NATTO.
Try NATTO on rice or on bread after stirring at least 50 times.
This is the starred NATOO in tasty mood.
And you can add sugar, pepper, sesami, egg or whatever you like (except for vinegar) to enjoy NATTO.
As I have been eating NATTO almost every morning for over twenty years, I can say I'm full of NATOO.
