Generally speaking, if both the pregnant woman and the fetus are in good health and the fetus is already relatively stable, eating longan in moderation will not cause miscarriage, but it needs to be judged according to each individual’s specific situation. Since longan has the function of activating blood, it is recommended that pregnant women should not eat longan if they have high blood sugar or if the fetus is not very stable in development. Longan has a good effect of benefiting qi and tonifying blood, strengthening the body and improving the symptoms of anemia, weakness, fatigue, insomnia, forgetfulness and dizziness in pregnant women’s bodies. Longan is rich in vitamins, proteins, glucose and minerals, which can supplement the nutrient needs of pregnant women and fetuses during pregnancy, so moderate consumption of longan is beneficial to the health of pregnant women and fetuses. In addition, pregnant women should work and rest regularly in daily life, avoid staying up late, pay attention to diet, do not eat spicy and stimulating food, and eat more high-protein, high-vitamin, easy-to-digest food, such as fresh vegetables, lean meat, milk, eggs, etc. In addition, proper supplementation of folic acid during pregnancy can prevent fetal neural tube defect malformation. Exercise in moderation to reduce edema in late pregnancy and prevent venous thrombosis in the lower limbs. If you take medication during pregnancy, be sure to take it under the guidance of your doctor and pay attention to regular maternity checkups.
