After World War II, Japan imported many new ideas from America. One of them was that a bread-based diet was better for our health. At that time, it was advertised widely that eating rice made you stupid (laughs). So for many years the Japanese Government provided only bread for school lunches. In Japanese homes, many people now eat bread or pasta at least once a day and we eat a lot of meat. And most meat and wheat — together with other products such as soy beans and corn — are imported mainly from the U.S. As a result, Japan’s food self-sufficiency has gone down from 80 percent in 1960 to only 39 percent in 2006.
