Provide heat Oils, proteins, and carbohydrates are the three major nutrients necessary for human survival. The fat has the highest heat-generating effect, and it is not easy for people to feel hunger if they consume enough fat. At the same time, it can protect organs and regulate body temperature. 2. Supply essential fatty acids The growth and metabolism of the human body cannot be reduced by fatty acids. Some fatty acids cannot be synthesized by the human body and can only be taken from foods, and the fatty acid content in oils and fats is the highest. 3. Supply of fat-soluble vitamins Vitamin A, vitamin D, and vitamin E can all be dissolved in the oil before being transported to various parts of the body and absorbed by the body. 4. Improve Appetite Edible oils can be seasoned to increase the taste of the dishes and to promote appetite and gastrointestinal digestion. Pregnant women eat oil should be based on vegetable oil Edible oils include vegetable oils and animal fats (such as lard, butter, butter, etc.). Animal fats have more saturated fatty acids and cholesterol and should be eaten less. In principle, pregnant women should use vegetable oil as their oil. Common features of vegetable oils are rich in unsaturated fatty acids (including oleic acid, linoleic acid and linolenic acid). Among them, oleic acid and linoleic acid can reduce cholesterol and protect blood vessels. The role. In particular, linolenic acid is important for pregnant women. After being absorbed by the body, it produces EPA and DHA. These two substances play an important role in the development of the fetus's nervous system, brain, and retina. Therefore, it is best to choose linolenic acid-rich oils during pregnancy. In addition, edible oil also contains certain vitamin A, vitamin D, vitamin E and mineral elements, etc., choose to eat edible oils with higher levels of these ingredients, are beneficial to pregnant women and fetal health. 8 kinds of edible oil suitable for pregnancy Which kind of oil is best for pregnant women?

Soybean oil Fatty acid composition is good, rich in linoleic acid, but also contains more vitamin E, vitamin D and rich lecithin, which is beneficial to the development of fetal nerves, blood vessels, and brain. Flaxseed oil Commonly referred to as "flax oil", it is rich in omega-3 unsaturated fatty acids (alpha-linolenic acid) and can be converted into DHA (a fatty acid in fish oil) in the human body. Lowering and ensuring the development of vision can also help. 3. Walnut oil It is rich in vitamin E and many trace elements, but also contains more unsaturated fatty acids such as linoleic acid and linolenic acid, which can promote the healthy balance of functions, improve memory, and benefit the brain development of the baby. 4. Peanut oil Contains oleic acid, lecithin and vitamin A, vitamin D, vitamin E, vitamin K and natural biological polyphenols with strong biological activity. It has anti-platelet aggregation and can prevent cardiovascular and cerebrovascular diseases. 5. Corn oil The ratio of monounsaturated fatty acid and polyunsaturated fatty acid is about 1:2.5, and it is also rich in vitamin E and a small amount of antioxidant substances. Its cholesterol-lowering efficacy is better than that of soybean oil, sunflower oil, and other high-linoleic acid oils. High nutritional health value. 6. Sunflower oil Rich in linoleic acid, α-linolenic acid, both in the body can be synthesized and brain nutrition-related DHA, after eating is conducive to fetal brain development. In addition, vitamin E, vitamin A, etc., can protect blood vessels, prevent dry eyes, night blindness and so on. 7. Olive oil It is said to be “liquid gold†and contains the highest monounsaturated fatty acids in edible oils, which can lower cholesterol and prevent cardiovascular and cerebrovascular diseases.

The quality of edible oil is directly related to the health of pregnant women and fetuses. In addition to picking regular brands, edible oils should also pay attention to the following aspects: View color Good quality soybean oil is dark yellow, generally light yellow; rapeseed oil is yellow with a bit of green or golden yellow; peanut oil is light yellow or light orange; cottonseed oil is light yellow, and sesame oil is orange or brown. Smell the odor by dropping one or two drops of edible oil on the palm of your hand. Carefully smell the odor after rubbing hands with friction and fever. No odor (hazel or pungent) can be purchased. Look at transparency High transparency, less water impurities, quality is good. The good vegetable oil, after standing for 24 hours, should be clear and transparent, not cloudy, no precipitate, no suspended matter. Such as poor transparency, increased viscosity, and bubbles, may be a sign of deterioration. Taste the taste with chopsticks, put a little oil into the mouth, if bitter, greasy smell, rancidity and other odors, should not be purchased or eaten. Water test Take one or two drops of oil at the bottom of the oil layer and coat it on a flammable paper. The combustion is abnormal and a “squeaky†sound is emitted, indicating that the moisture in the oil has exceeded the standard and is an unqualified product. When a "bang" explosion sounds while burning, it means there may be impurities in the oil. Look at the packaging Note whether the expiration date and production date on the mark expire. No manufacturer's QS mark and QS number, or no manufacturer's name, site, product standard number, can not buy. It also depends on the processing technology. Selecting the pressed oil is safer and more reliable than leaching the oil. Eight ways to teach you science and eat oil correctly Different edible oils contain vitamins and other nutrients that differ in the proportion of fatty acids they contain. They also have different stability when exposed to heat, so pregnant mothers must learn to eat oil scientifically and correctly. 1. Change to eat more nutritious Each kind of edible oil contains different nutrition and stability, so do not choose only one kind of oil to eat, eat alternately, so that pregnant women can absorb a variety of fatty acids, balanced nutrition. 2. Excessive oil temperature Monounsaturated fatty acids become saturated fatty acids and other harmful substances at high temperatures, and nutrients in the oil are lost. It is recommended that the pan be heated and then pour the oil before cooking. Don't wait until the oil has smoked before cooking. Like soybean oil, corn oil, sunflower oil and other heat-resistant poor performance, it is best not high-temperature cooking. 3. Learn how to "control oil" Modern people tend to eat too much oil and pregnant women need to control excessive oil consumption. Can use non-stick pans, microwave ovens, etc., can use less pot oil, reducing the amount of oil. Cooking uses more cooking, stewing, steaming, mixing, etc., but also less oil. The daily amount of oil consumed by pregnant women should be about 25 grams (about two teaspoons), which can meet their own and the fetus's need for fat. 4. A small amount of edible animal oil is also beneficial Excessive eating of animal fats can be harmful to health, but it is not necessary to fast. Animal oils such as lard also have functions such as protecting the skin and maintaining body temperature. A small amount of food is also beneficial, generally not exceeding 1/3 of the total daily oil intake. 5. Disable repeated frying Do not eat oil repeatedly used to fry foods, but do not use frying oil to cook. Because of the repeated use of oil, nutrient components are lost, and many harmful substances are also produced, which is unfavorable for maternal and fetal health. 6. Do not eat bulk oil, expired oil Unknown bulk fat production date, its quality can not be guaranteed, it is very likely to have problems, eat a harmful health, pregnant mothers do not want to buy cheaper. Oils that exceed the shelf life are also firmly rejected. 7. The special function of the oil to eat less Some edible oils are marked with good hypolipidemic, anti-ageing and other functions, such as evening primrose oil, safflower seed oil, almond oil, perilla oil, garlic oil, etc. These oils are mainly targeted at patients with chronic diseases, elderly, etc. The crowd, whose nutritional value is not good, is less preferred for pregnant women. 8. Choose a small bottle of oil Fatty acids are prone to oxidation. The oil is filled in small bottles and eaten easily in a short time. The oil is fresh. The large bottled cooking oil can't be used for a long time. The remaining nutrients of edible oil are easily damaged or even deteriorated. Edible oil preservation tips Edible oil has "four fears", that is, fear of light, fear of high temperature, fear of not sealing, afraid of water. Therefore, the following points should be noted when saving: The optimum storage temperature for low temperature storage is 10 to 25°C. When not in use, besides away from the stove, you should avoid places close to heating pipes, high-temperature electrical appliances and so on. It is best to store the edible oil in the dark and in a ventilated place in the dark, because the ultraviolet and infrared rays in the sunlight will also promote oxidation of the grease and formation of harmful substances. Selected containers Containers for oil storage must be clean, dry, and well sealed. It is best to use dark glass instead of transparent glass bottles. Plastic buckets should not be used for long-term oil storage, metal containers should not contain oil, they will accelerate the rancidity of grease. Avoid influent new bottled oil, be careful not to bring in water, the bottle already has water, to wipe or heat to evaporate and then bottled oil, otherwise the oil is susceptible to deterioration. Preservation time The cooking oil should be eaten within 3 months. Generally, it should be kept for half a year and it should not exceed one year.
