2. Don't eat a lot of pickles for a long time. Because pickles contain nitrite, if eaten in large quantities for a long time, nitrite will enter the fetus through the placenta, which is not conducive to the development of the fetus. And the content of sodium salt in pickles is high. Eating pickles for a long time will cause sodium and water retention, and may also lead to edema and high blood pressure.
3. Eat healthy and diversified diets during pregnancy, eat more fresh vegetables and coarse grains, and supplement high-quality protein and rich nutrition, such as lean meat, eggs and milk, every day.
