At this time, the uterus has occupied more than half of the abdomen, and the pregnant woman's stomach is squeezed, which affects her appetite, so she often feels underfed. During this period, the maternal basal metabolic rate increased to the peak, and the fetal growth rate also reached the peak. It is necessary to supplement the nutrition reduced by the decrease of stomach capacity as much as possible, eat more meals a day, and take a balanced intake of various nutrients to prevent obesity and stunting. In this month, the fetus began to store sugar and fat in the liver and under the skin. At this time, if the carbohydrate intake is insufficient, it will lead to the decomposition and mobilization of protein and fat in the mother's body, which will easily lead to protein deficiency and ketoacidosis. Therefore, to ensure the supply of calories in August, besides a large amount of glucose for the rapid growth of the fetus and the storage of glycogen and fat in the body, a certain amount of fatty acids, especially linoleic acid, is needed. At this time, it is also the peak of cerebral hyperplasia, and the cerebral cortex proliferates rapidly. Rich linoleic acid can meet the needs of brain development.
