As we all know, when Japan often eats raw food, sashimi is a Japanese feature. What kind of sea urchin rice and sweet shrimp rice are all raw seafood that can be eaten directly with a knife. The new raw octopus is their feature there.

So why do Japanese dare to eat raw food like this? After all, raw things still feel unsanitary. However, if you look closely, you will find that the Japanese like mustard very much, and even dipping avocado slices in mustard soy sauce is their idea. Mustard is not used to by many people, and it feels stiff and uncomfortable, but mustard is a good thing. Mustard is very nutritious, and its spicy taste mainly comes from mustard oil, which can make people appetizing and detoxifying. It can kill germs and parasites in the stomach, so eating raw seafood can't guarantee no parasites because it is not heated, so mustard is needed to sterilize and kill insects. And it can treat rheumatism, which is a good thing for people who often eat seafood. Of course, don't eat too much, it will hurt your stomach.

The second reason is Japan's strict requirements for raw food. They are very strict about the food itself. Because it is an island country, the fish are very fresh. The sashimi they eat is basically the fish slaughtered and dissected that day. Ice is an indispensable thing in Japanese seafood market. If there is a problem, throw it away or cook it immediately. Unsafe food will not flow into the raw food market. Moreover, the sashimi they eat is required to be finished as soon as possible, just to keep it fresh until the last moment. Moreover, the parasites in the sea are much better than those in rivers, so they are still relatively safe. In addition, the sterilization and detoxification ability of mustard is just like sterilization when we cook it, which will be much safer.
