Fats serve as a source of energy and essential fatty acids to aid in the absorption of fat-soluble vitamins. Fat is the main body of caloric energy, and the fatty acids contained in it are indispensable substances that constitute the body's cells and tissues, and increasing the intake of high-quality fats is beneficial to pregnancy. The nutritional value of a fat is related to the type of fatty acid it contains. Fatty acids are divided into saturated fatty acids and unsaturated fatty acids.
Linoleic acid, linolenic acid, 3 unsaturated fatty acids, etc. are all unsaturated fatty acids that cannot be synthesized in the human body, and can only be supplied by food, also known as essential fatty acids. Essential fatty acids are mainly found in plants and are essential nutrients for the human body. Insufficient absorption of essential fatty acids can cause a person to suffer from a variety of diseases such as rashes, hematuria, and lactation disorders. The essential fatty acids needed by the fetus can only be produced by the mother through the placenta**, so in order for the fetus to develop properly, women who want to get pregnant should eat more vegetable oils. Animal fats and fats contain high levels of saturated fatty acids, but without a reasonable combination of saturated fatty acids and the other two types of fatty acids, health problems will also occur. Lipids remain one of the most important parts of the body's energy**.
Energy fats are indispensable nutrients for human beings, and if too little fat is absorbed, it will cause insufficient caloric intake and a lack of essential fatty acids, which is harmful to embryonic and infant development and maternal health. Sugars account for 60 70 of the total caloric intake, which is about 500 grams of staple food per day. Sugars such as rice, whole grains, and dried and fresh beans are converted into heat for the body. Therefore, if there is a lack of calories, the body's absorption of these nutrients will be affected, and nutrient deficiency will occur. If you eat too much, it will be converted into fat and cause blood sugar to rise, which can damage fertility. The role of heat energy is to ensure that other nutrients work in the body, and sperm and other physiological activities also rely on sufficient heat energy.
Therefore, before pregnancy, it is necessary to ensure an adequate supply of energy, and it is best to add 200 400 kcal on the basis of the normal daily supply of calories, so as to accumulate a part of the energy for conception, so as to "strengthen the egg" and create the necessary conditions for conception and eugenics.
