It is true Japanese eat a lot of fish, but that began to change many years ago. They eat huge amounts of red meat as well. They love deep fried food and also have a very healthy and broad consumption of vegetables. Fast food in Japan is rampant. The youth in Japan are very different from generations before. Mentally, physiologically, culturally they have undergone radical transformation from the Japanese of the baby boomer generation upon which far too many assumptions are made.
