Can you eat gluten (seitan) during early pregnancy?
In general, whether a pregnant woman can eat gluten (wheat gluten) during the first trimester should be determined based on her individual health condition and digestive capacity. If there are any concerns or discomfort, it is recommended to consult a doctor promptly. The detailed analysis is as follows:

If the pregnant woman is in good health, has no gluten allergy or intolerance, and possesses strong digestive function, consuming gluten in moderation is acceptable. Gluten is primarily composed of wheat protein and provides high-quality protein that helps maintain maternal bodily functions and supplies essential materials for fetal organ and tissue development. Choosing lightly cooked gluten dishes can reduce gastrointestinal burden, and pairing them with vegetables ensures balanced nutrition, meeting basic prenatal nutritional needs.
However, if the pregnant woman has a gluten allergy, celiac disease, or weak digestion, she should exercise caution when consuming gluten. Individuals with gluten sensitivity may experience rashes, diarrhea, abdominal pain, or other adverse reactions after consumption, which in severe cases could affect both maternal health and fetal development. For those with poor digestion, the dense protein structure in gluten may easily lead to bloating and indigestion if consumed excessively, worsening gastrointestinal discomfort common during pregnancy.
Purchase fresh gluten from reputable sources to avoid spoiled ingredients that might cause digestive issues. Use minimal spicy or greasy seasonings during cooking to reduce irritation to the digestive system. When trying gluten for the first time or if digestive concerns exist, start with a small amount and observe the body's response. If any adverse reactions occur, discontinue consumption immediately and consult a healthcare provider.
