Carbonated beverages can be consumed while pregnant, but it is not recommended to consume them in large quantities or for a long period of time. Carbonated beverages are common beverages that can be consumed by ordinary people and do not harm pregnant women or fetuses per se, so they can be consumed in small quantities. However, carbonated beverages contain high sugar content, high calories and low nutritional value, so long-term consumption of large quantities may lead to rapid weight gain and rapid rise in blood sugar in pregnant women, which may affect the growth and development of the fetus. Diet during pregnancy should be nutritionally balanced and diversified. It is better to drink some plain water or fruit juice squeezed by yourself during pregnancy, which does not contain any additives, and do not eat food that is too spicy or too cold.
