During pregnancy, you can eat nuts such as peanuts, melon seeds, walnuts, almonds, pine nuts, hazelnuts, etc. The content of these foods is as high as 44%-70% of oil and 12%-25% of protein. In addition, there are lotus seeds and chestnuts with high starch content. These dried fruits mainly provide the body with essential fatty acids and fat-soluble vitamins, such as vitamin E and vitamin K, which are essential foods during pregnancy. Lipids are vital to the development of the fetal brain and nervous system. Lipids are the main components of the brain and nervous system, and about 1/3 of the amount of fetal brain fat is macronutrients linoleic and linolenic acid. In the process of fetal brain development, without the right amount of essential fatty acids, the division of brain cells will be delayed. Therefore, pregnant women should have 3g-6g of essential fatty acids daily, as well as the right amount of phospholipids and cholesterol, to ensure the normal development of the fetal brain nervous system, which can be obtained from dried fruits.
