For the recipe of gestational diabetes mellitus, rice, steamed bread, flower rolls, noodles and jiaozi can be used as staple foods, but the amount of each meal is limited. Three meals a day is the best, and the staple food for each meal should not exceed 100g.

The protein supply of gestational diabetes mellitus patients is close to that of normal people, which is generally 1.0g per kilogram of body weight per day. However, when the disease is not well controlled, the consumption of protein increases, often showing negative nitrogen balance. Therefore, the supply of protein should be appropriately increased, generally 1.0 ~ 1.5g/kg per day, in which high-quality protein should account for 1/3 ~ 2/3 of protein's intake, and the heat energy supplied by protein accounts for 10% ~ 20% of the total heat energy.

Vegetables that can be eaten for gestational diabetes include green leafy vegetables, such as spinach, Chinese cabbage, celery, leek and lettuce. And carrots can be eaten three times a day between 500 and 800 grams.
