Pregnant women can consume a small amount of puffed snacks like shrimp crackers, but not in large quantities. There are various types of puffed foods, in addition to shrimp crackers, there are also other varieties such as potato chips, rice cakes, etc. Eating a small amount of these snacks can stimulate appetite without affecting the overall dietary structure, which is generally acceptable. However, they should not be consumed in large amounts. Puffed foods are made through frying, containing high calories but low nutritional value. If a large amount of these foods are consumed, the intake of other foods will be relatively reduced, which can easily lead to obesity in pregnant women. It may also affect the health of pregnant women due to unbalanced nutrient intake, indirectly causing fetal growth retardation. Puffed foods usually contain puffing agents, flavors, colors, and other raw materials. If they are inferior quality, consuming a large amount may harm fetal development, even causing fetal malformations and miscarriages. Pregnant women should also avoid drinking carbonated beverages, coffee, tea, and other such drinks as much as possible. They should eat fresh green vegetables, fruits, lean meat, and other natural and healthy foods to benefit their own health and the health of their fetuses.
