The reason for the increasing number of patients with diabetes is the improvement of people’s living standard, the change of diet structure (eating more high-fat and high-protein foods and less fiber foods), the corresponding reduction of physical activity, the large number of obese people, and the increase of life expectancy. It is also related to the importance people attach to diabetes and the census, and the improvement of diabetes diagnosis and treatment technology. As long as we improve diabetes health education, let people develop a good lifestyle, take the correct, scientific eating habits, long-term adhere to the exercise, avoid obesity, avoid alcohol and quit smoking to maintain good mental health will be able to reduce the incidence of diabetes to a minimum level.
