In fact, gestational diabetes refers to those who have not had diabetes in the past, but have shown signs of elevated blood glucose during pregnancy, which meets the criteria for diagnosing diabetes, and is called gestational diabetes. If you have diabetes in the past and then get pregnant, it is generally called diabetes in combination with pregnancy. Although the order of appearance of the two states is not the same, but in the principles of dietary treatment and recipe development have certain similarities. So it will not be listed separately. First, the principles of treatment 1, energy: early pregnancy energy intake and pre-pregnancy the same, mid-term and late pregnancy, according to the Chinese residents of the reference intake of dietary nutrients, an appropriate increase in order to meet the needs of the mother and the growth and development of the fetus. Obese pregnant women (BMI>30) are not required to lose weight during pregnancy, but only required to control the rate of weight gain. Energy supply is not static, need to monitor the mother’s weight, the more ideal growth rate: early pregnancy growth 1-2Kg, mid-term and late pregnancy, weekly growth of 0.3-0.5Kg (obese weekly growth of 0.3Kg), so that the total growth of pregnancy 10-12Kg (obese pregnant women increased 7-9Kg). In addition, pregnant women should also carry out a moderate amount of exercise. 2, the distribution of the three major thermogenic nutrients: protein provides energy accounted for 15-20% of the total energy, fat accounted for 25-30%, carbohydrates accounted for 55-60%. The supply of protein varies according to the period of gestation. Carbohydrates in early pregnancy and the same as before pregnancy, mid-term and late pregnancy will increase. 3, minerals and vitamins: required to meet the “Chinese residents dietary nutrient reference intake” in the level required by pregnant women. 4, meals: require a small number of meals, in addition to three meals, and three additional meals, to prevent and control ketosis is favorable. 5, dietary control: if the postprandial blood glucose is still > 8mmol / L (140mg / dl), it is an indication for insulin therapy. During pregnancy, the patient’s nutritional intake and meal plan should be adjusted according to the patient’s appetite, weight, blood glucose, ketonuria, lipids and other monitoring indicators. 6. Alcohol should be prohibited during pregnancy.

Total energy is 1,727Kcal, protein is 56g (13%), fat is 43g (22%) and carbohydrate is 279g (65%).
