Patients with gestational diabetes should pay attention to the following points in their diet:

1. Avoid high-sugar foods, such as candy, cakes and sweet drinks, which will lead to a rapid increase in blood sugar.

2. Avoid high-fat foods, such as fried food and fat meat, which will increase insulin resistance and make blood sugar control more difficult.

3. Avoid refined foods, such as white bread, white rice, etc. These foods release sugar quickly, which may easily lead to high blood sugar.

4. Avoid excessive intake of protein: Excessive intake of protein may increase the burden on the kidneys, which is not good for pregnant women and fetuses.

5. Avoid drinking: Alcohol will affect the function of the liver, reduce the sensitivity of insulin, and make blood sugar control more difficult.

6. Avoid excessive hunger or satiety: this may lead to excessive blood sugar fluctuation.

7. Avoid eating too much fruit: Although fruit is a healthy food, it also contains sugar, which needs to be taken in moderation.

8. avoid eating too much salt: too much salt intake may lead to an increase in blood pressure, which is not good for pregnant women and fetuses.

The above are some basic dietary taboos, and the specific diet plan needs to be made according to the individual's physical condition and the doctor's advice.
