Last night we went to the end of year party (Bonenkai) at one of the best fish restaurants in Tokyo's Tsukiji fish market. It was really the best in the world!! Sashimi, raw fish slice, was very oily and rich flavour and there was a huge grilled sea bream as well. Here I want to review the concept of raw fish eating in the West. Sushi and sashimi are now known as healthy and low calorie food, and I have seen many women eat them quite often in lunch. Traditionally Japanese eat fresh raw fish at the special occasions such as celebrations or anniversay, although the frequencies increased last 100 year or so. It had been considered as a luxury meal (probably not so much anymore), and actually the secret of Japanese longevity is among simple home cooking which doesn't include raw fish as a everyday food. Yes, eating raw fish can achive low calorie diet - a single portion of sashimi is around 300 to 600 calories -, and also contains many beneficial nutrients such as essential fatty acids (omega-3). However we must know about the risk of bacterial infection. Try purchase from trusted shops and eat the vegetable side portion as well. There is a reason why thinly stripped white radish is accompanied, as it can kill the bacteria. If you prepare raw fish at home, then you should freeze them for at least 2 days before use them (defrosted). Also if you feel unwell, do not eat sushi or sashimi as your immune system might be weaken and can be more susceptible to infection. You are advised not to eat raw fish when you are pregnant as well.
