We visited Yuzuri Hara some years ago to interview the residents about their daily lives. Apparently the population in Yuzuri Hara lives much longer than any place in Japan.
We were told that the water in Yuzuri Hara is fresh and free from pollution. They don’t use pesticides on their crops. Researchers claim that the reason why this society lives so long and healthy is because of an ingredient in their food called hyaluronic acid. Many companies have tried to exploit this chemical by producing it in the form of pills, cream and other edible products.
I believe that the food that they eat is not the only reason why these people are so healthy. I’m sure it has something to do with their behavior as well.
