The program "Mr. Hayashi's right now" was talking that the above-mentioned fermented food was good for both the body and the brain. And in general it is said that it is better not to eat meat etc. and vegetable is better when you are aged, but there is also a story that meat is necessary even if it is older. I think that it is a story based on recent research data, but vegetarians who do not eat at all such as meat and fish have data that they are healthy more than general people physically and mentally and have long lives. So I can’t always recommend the meat is good for health, but I recommend that yoghurt, natto, and miso soup are truly good for health.
