Six principles of diet for gestational diabetes Principle 1: No increase in calories in the early stages, 30 calories/kg/day required in the middle and late stages. Late pregnancy can be increased by 200 calories per day on top of this. You should not lose weight during pregnancy. Principle 2 ： Pay attention to meal distribution. To maintain a stable blood glucose level and avoid ketonemia, have small and frequent meals, divided into 5 to 6 meals. Take a snack before bedtime. Principle 3: The intake of sugar is to provide calories, maintain normal metabolism, and avoid ketosis. It should not be mistaken that not eating starch can control blood glucose or weight, and not eating at all; instead, sugary drinks and sweet foods should be avoided as much as possible, which can avoid rapid blood glucose increase after meals. A small amount of sugar substitute can be added, if needed. It is recommended that you try to choose unrefined staple foods with high fiber content,. Pregnant women with gestational diabetes have higher blood sugar levels in the morning’ so breakfast starchy foods must be less. Principle 4: Focus on protein intake. If you have taken enough nutrients before pregnancy, you do not need to increase your protein intake in the early stages of pregnancy, but you need to increase the amount of protein in the middle and late stages of pregnancy by 6 grams and 12 grams each, half of which should come from high physiological value proteins, such as eggs, milk, dark red meat, fish and soy milk, tofu and other soy products. It is best to drink at least two glasses of milk every day to get enough calcium, but never drink milk as water to avoid high blood sugar. Principle 5: Be careful with fats and oils. Use vegetable oil as the main cooking oil, reduce deep-fried, fried, crispy food, as well as animal skin, fatty meat, etc. Principle 6: Consume more fiber. Within the range of intake, take more high-fiber foods, such as brown rice or grain rice instead of white rice, increase the intake of vegetables, eat fresh fruit instead of juice, etc. This can slow down the rise of blood sugar, help control blood sugar, and also feel fuller. But do not eat unlimited amounts of fruit.
