There are hundreds of oil products on the market, how to use oil correctly is a university question. Feng Dunci, a nurse at the Clinical Toxic Center of Changgeng Hospital of Linkou, said that many people think that "eating oil will cause evil", but not eating oil will cause many problems. The skin is prone to aging, dullness, and lack of lust. Studies have found that if you do not eat oil during the reduction period, the situation will be difficult to control and easily distract. Therefore, it is very important to take appropriate oil into the body, but it is absolutely necessary not to "one oil to the end".
Different oils have different smoke points, especially now that the weather is changing, many people like to come to a bowl of sesame oil to warm up. Some shops cook sesame oil and chimes everywhere, and the sound is full of light. Yu Dunci admitted that he was afraid of seeing sesame oil cooked like this. The sesame oil smoke point was 177℃. When cooking, stir-frying with sesame oil when the heat is very high and the pot is very hot, not only will it produce oil smoke, but the oil will change, which will easily cause damage to the body. In fact, as long as the sesame oil is changed, the situation will be different.
Some people cook sesame oil chickens, and they are used to heat the pot first, then pour in sesame oil, and wait until the sesame oil is smoked, then pour in the pot and stir-fry it. Then, the chicken is slurry and then pour wine. At this time, there will be a raging fire in the pot. Yu Dunci pointed out that sesame oil is not resistant to high temperatures. If you use this high temperature cooking method, sesame oil will exceed the smoke point in one go. According to the information on the "Harvard Health" website of Harvard University in the United States, once the oil exceeds the smoke point, it will often cause bitterness, nutrient loss, and oil smoke will be produced. When these oil smoke enter the human body, it will naturally bring adverse effects.
In order to avoid sesame oil from deteriorating healthy good products into a devil of injury, Yu Dunci suggested that when cooking sesame oil, you can first use bitter tea oil, black rice oil or grape seed oil to stir-fry the smoke points. The smoke points of these oils often exceed 200℃, and the oil is relatively stable. Stir-fry with oil. After ginger, put the chicken down, add water and add sesame oil. At this time, the medium temperature of the pot drops below 177℃, which can retain the original flavor of sesame oil. The healthy nutrients in sesame oil will be fully locked and not lost. More importantly, this will not produce oil and smoke, which is better for health.
When choosing healthy oil, pay attention to the ratio of "this ingredient"!Zhu Dunci emphasizes that choosing suitable oils mainly depends on the cooking method at home. Many oils are suitable for mixing, but not for high-temperature cooking. The healthy ingredients of each oil are also slightly different. Like her, she likes to use grape seed oil when she frys fish, because the smoke point is 200℃, and it is better to fry things.
The principle of choosing oil, Yu Dunci suggested that you can choose oils with a higher ratio of "unstainless to fatty acids". Unstainless to fatty acids will increase good calcium sterols. For example, bitter tea oil, monosodium to fatty acid ratio of 83%, olive oil reaches 73%, or canola oil is about 63%, which are all very good oil choices. If you choose polyvinyl fatty acids such as sunflower oil, soybean oil, etc., good and bad sterols will increase; if you contain raw sterols such as pig oil, it will increase the bad sterols, and eating them regularly will be detrimental to cardiovascular health.
Grease is an important part of a healthy diet. For fat and fat extraction, the American Heart Association recommends that each person should take 3 tons or 9 teaspoons of fat or fat every day, and replace coconut oil, palm oil, animal oil and other oils with liquid vegetable oil as much as possible. This will be more in line with the principles of healthy diet.
