Is dietary restriction necessary for maintaining a pregnancy?

In general, dietary restrictions are necessary during fetal preservation. The specific analysis is as follows:

During fetal preservation, a balanced diet should be maintained, ensuring adequate intake of various nutrients including protein, carbohydrates, fats, vitamins, and minerals. It is advisable to consume more protein-rich foods such as lean meat, fish, legumes, and soy products; include moderate amounts of healthy fats from sources like vegetable oils and nuts; and increase consumption of fresh fruits, vegetables, and whole grains. Raw or cold foods should be avoided as much as possible, such as sashimi, raw fruits and vegetables, and chilled beverages, because these may carry bacteria or parasites that could lead to food poisoning and negatively affect fetal health. Excessive caffeine intake may increase the risk of miscarriage, so caffeine consumption should be limited during this period. Caffeine is primarily found in coffee, tea, chocolate, cola, and similar foods and drinks, so it is recommended to reduce or avoid consuming these items. Spicy and irritating foods such as chili peppers, Sichuan pepper, and ginger should also be avoided, as they may irritate the gastrointestinal tract and cause discomfort for both the fetus and the pregnant woman.

Overeating should be avoided, and weight gain should be controlled. Excessive eating can lead to rapid weight gain, increasing the risk of gestational diabetes, hypertension, and other complications, which may adversely affect fetal development.
