There is no food in the second trimester of pregnancy that can only make the fetus grow but not the baby. All food consumed is absorbed by the mother and then passes through the placental barrier before being supplied to the fetus, so whatever you eat first directly affects the pregnant woman and then indirectly affects the fetus, so there is no food that can only cause the fetus to grow without causing the mother to grow. How much a pregnant woman will gain in weight and the size of the fetus will be affected by many factors, first of all, the dietary structure of the pregnant woman and the amount of food she eats, and secondly, her blood sugar, blood lipids, the uterus, the blood circulation of the placenta and the umbilical cord, as well as the fetus’s own individual differences, growth and development. If the fetus is too big or too small, it is not good for the health of the fetus. During pregnancy, you must pay attention to balanced nutrition, don’t be partial to any kind of food, and don’t be over-nourished or malnourished. It is important to follow the doctor’s instructions to do regular checkups to avoid high blood sugar or over-nutrition, which may lead to a huge baby, and the baby should be examined to find out the cause of the baby’s small size, and corrected accordingly.
