The dietary status of contemporary college students is analyzed as follows:

Comparison of dietary health of students of different sexes. There is no significant difference in nutrition knowledge between boys and girls (U=1.98, P> 1.15), which may be related to the same main channels for medical college students to obtain nutrition knowledge, all through the teaching of teachers in class.

However, there are gender differences in healthy eating behavior between men and women, which may be due to the relationship between men and women's personalities. Boys tend to pay less attention to the details of life and pay more attention to sports, while for girls, more girls pay more attention to diet, because a lot of information provided by modern society shows that diet is related to good figure and face, especially the content of our survey.

Insisting on eating breakfast every day, as well as fully supplementing milk and fruit, has been formulated as a beauty diet by many girls. In the use of snacks, girls are obviously higher than boys, which is related to girls' living habits.

Comparison of dietary health status between urban and rural students. The survey results show that there are significant differences in dietary behavior between rural and urban students. This is related to the spending power of two kinds of students. For students, the daily consumption of milk and fruit takes up a large proportion of the living expenses.

Therefore, for students with relatively good family conditions, they have the ability to eat every day, but for students with poor heaven conditions, it is only used as a nutritional supplement occasionally.

Another reason for this difference is also related to the living habits of urban and rural areas. Most urban residents have formed the dietary habit of drinking milk and eating fruit every day, while rural residents have low requirements for dietary nutrition. In the survey of breakfast habits, rural students have better breakfast habits than urban students, which may be related to the good work and rest and dining habits developed by rural students at home.
