Pregnant women can eat matcha cake, but they need to pay attention to a small amount of food to avoid eating too much. Because the cake is high in sugar, it is easy to lead to high sugar status of pregnant women, increase the risk of gestational diabetes and the risk of macrosomia. Matcha cakes are mostly sugar and starch, which can't provide nutrients such as protein and minerals. Eating too much will reduce the intake of other foods, which may lead to nutritional deficiency. The diet during pregnancy needs to be light and hygienic, but it is also rich in nutrients, especially in the first and third trimesters, so as to avoid the abnormal development of the fetus due to the lack of nutrients. Need more rest during pregnancy, avoid overwork and staying up late, quit smoking and drinking.
