Early pregnancy is the period for the differentiation of heart, liver, kidney, intestine, stomach and other vital organs. As a result, it is necessary to obtain a variety of adequate nutrition. Otherwise, the early development of fetus will be greatly affected, leading to fetal underweight or developmental abnormalities.
