The incidence of heart disease in China is much lower than the incidence of heart disease in the United States  The rate of heart disease for Chinese people who immigrate to the United States approximates the higher rate of heart disease prevalent in the United States
However, most Chinese people continue to eat the same type of food that they ate in China after they immigrate to the United States
The relatively low rate of heart disease in China is not due to the different food eaten by the Chinese people.
