Japan's Dietary Transition and Its Impacts

1 Comment

In a little more than a century, the Japanese diet has undergone a dramatic transformation. In 1900, a plant-based, near-subsistence diet was prevalent, with virtually no consumption of animal protein. By the beginning of the 21st century, Japan’s consumption of meat, fish, and dairy had increased markedly (although it remained below that of high-income Western countries).

In their book, "Japan's Dietary Transition and Its Impacts," authors Vaclav Smil and Kazuhiko Kobayashi examine how this dietary transition was a key aspect of the modernization that made Japan the world’s second largest economic power by the end of the 20th century. They look at how it has helped Japan achieve an enviable demographic primacy, with the world’s highest life expectancy and a population that is generally healthier (and thinner) than that of other modern affluent countries.

The book examines Japan’s gradual but profound dietary change and investigate its consequences for health, longevity, and the environment.

Smil and Kobayashi point out that the gains in the quality of Japan’s diet have exacted a price in terms of land use changes, water requirements, and marine resource depletion; and because Japan imports so much of its food, this price is paid globally as well as domestically. The book’s systematic analysis of these diverse consequences offers the most detailed account of Japan’s dietary transition available in English.

not all Japanese are thin a lot of the are not that's not diet it's genetics, a lot of Japanese that should not be thin are force by social stress to be thin and they count every calorie and are always on a diet. eating health foods and not intake to much food is being embrace by many modern cultures, getting back to how we all use to eat that trait did not being in Japan it is something shared the world over. Meat and fish is needed to do real work but if we eat smaller portions and have more vegetables that are in season, allows us to be a lot healthier again that is not something specifically unique to the Japanese.
