The function of fat is to supply heat energy and essential fatty acids to help absorb fat-soluble vitamins. Fat is the main source of heat energy in the body, and the fatty acids it contains are indispensable substances that constitute the cells and tissues of the body. Increasing the intake of high-quality fat is beneficial to pregnancy. The nutritional value of fat is related to the types of fatty acids it contains. Fatty acids are divided into saturated fatty acids and unsaturated fatty acids.
Linoleic acid, linolenic acid, ω3 unsaturated fatty acids, etc. are all unsaturated fatty acids that cannot be synthesized by the human body and can only be supplied by food, also known as essential fatty acids. Essential fatty acids are mainly contained in plants and are essential nutrients for the human body. Insufficient absorption of essential fatty acids can cause people to suffer from various diseases such as rash, hematuria, and lactation disorders. The essential fatty acids needed by the fetus can only be supplied by the mother through the placenta. Therefore, in order to allow the fetus to develop normally, women who want to become pregnant should eat more vegetable oils. Animal fats and oils contain a high level of saturated fatty acids, but without a reasonable combination of saturated fatty acids and the other two types of fatty acids, health problems may arise. Lipids remain one of the body\’s important sources of energy.
Energy fat is an indispensable nutrient for human beings. If too little fat is absorbed, it will cause insufficient heat energy intake and lack of essential fatty acids, which will be harmful to embryo, infant development and maternal health. Carbohydrates account for 60% to 70% of the total energy intake, which is approximately 500 grams of staple food per day. Sugars such as rice, whole grains, and dried and fresh beans will be converted into heat energy for the body\’s needs. Therefore, if there are insufficient calories, it will affect the body\’s absorption of such nutrients, leading to nutritional deficiencies. If you consume too much, it will be converted into fat and cause blood sugar to rise, which will damage fertility. The function of heat energy is to ensure that other nutrients take effect in the body. In addition, sperm and other physiological activities also rely on sufficient heat energy.
Therefore, it is necessary to ensure an adequate supply of energy before pregnancy. It is best to add 200 to 400 kcal to the daily caloric supply required by normal adults to save some energy for conception, so as to \”strengthen the sperm and eggs.\” ”, creating the necessary conditions for conception and eugenics.
