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. Pickles are high in sodium salt. Eating pickles for a long time will cause sodium and water retention, and may also lead to edema and high blood pressure.
3. Eat a healthy and diversified diet 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.
