The publication of "Dietary Guidelines for China Residents in 2007" provides a guiding direction for China residents to eat healthily. A reasonable diet is the foundation of health. The working people in our country have long put forward the views of "dietotherapy" and "food doctor", which means that health is eaten, and some diseases can be cured by adjusting diet. Nowadays, many people have not realized this, so that their living standards have improved. Many diseases that should not have come, such as diabetes and hyperlipidemia, are food-borne diseases caused by improper diet, and these diseases are increasing year by year and gradually becoming younger. This has greatly affected the improvement of our national quality and caused a great waste of resources; It is urgent to implement the Dietary Guidelines for China Residents 2007.
