What are the benefits of eating walnuts during the second trimester of pregnancy for the fetus?

Generally, consuming walnuts during the second trimester of pregnancy offers several benefits for the fetus, including nutritional supplementation, promoting fetal brain development, antioxidant effects, preventing neural tube defects and anemia, and supporting bone development. The detailed analysis is as follows:

1. Nutritional supplementation: Walnuts are rich in protein, fats, fiber, vitamins, and minerals, which play an important role in fetal growth and development, meeting the high nutritional demands of the fetus during mid-pregnancy.

2. Promoting fetal brain development: The fatty acids in walnuts help form and connect neurons, enhance cognitive function, and promote the fetus's learning and memory abilities.

3. Antioxidant effects: Walnuts contain abundant antioxidants that help reduce oxidative stress and inflammatory responses in both the pregnant woman and the fetus, protecting fetal cells from damage.

4. Preventing neural tube defects and anemia: Walnuts also contain folic acid, a crucial nutrient for preventing fetal neural tube defects. Additionally, the iron in walnuts helps prevent maternal anemia, thereby ensuring the fetus receives sufficient oxygen and nutrients.

5. Supporting bone development: The calcium and other minerals in walnuts contribute to fetal bone growth and strengthening, laying a solid foundation for future development.

Pregnant women should ensure timely nutritional intake in daily life and moderately consume nutrient-rich foods such as eggs and pork ribs, which are beneficial for fetal development.
