Pregnant women with high fasting blood glucose should maintain a low-salt, low-fat and low-sugar diet, while ensuring balanced and comprehensive nutrition to avoid affecting the development of the fetus. Pregnant women with high fasting blood glucose should control the amount of food they eat every day, eat a low-salt, low-fat, low-sugar diet, and pay attention to nutritional balance and comprehensiveness, so that they can provide a certain amount of calories to ensure the nutrition of the pregnant mother and the fetus, without causing blood glucose abnormalities. It is recommended to have small and frequent meals, balanced diet to control weight gain, and choose foods with low glycemic index as much as possible, such as fresh vegetables, low-sugar fruits, milk, fish, meat, soy products, coarse grains and other foods, avoiding unhealthy foods such as fatty meats, deep-fried foods, sugary drinks and creamy cakes. Pregnant women with high fasting blood glucose can consult their doctors for specific diets and regular medical check-ups.
