What is the most unhealthy oil? Is it soybean oil? Remind everyone: with these 3 kinds of oil, try to eat as little or no as possible.
People take food as their life, and cooking oil is indispensable when cooking food. In recent years, with the increasing attention to food safety and health, the selection and use of edible oil has also become the focus of attention. As one of the common cooking oils, soybean oil has been controversial about whether it is healthy or not. So, is soybean oil really the least healthy, as some say?
First, let's clear up some misconceptions about soybean oil. Soybean oil is a kind of vegetable oil, soybean oil in the extraction process, although there will be a certain amount of organic solvents and other impurities mixture, but these substances have a very low boiling point and are easy to volatilize and remove, so the residue is far from enough to cause harm to the human body. Some people consider soybean oil unhealthy, mainly because it contains a certain amount of trans fats. However, in practice, vegetable oils are refined to produce a lower level of trans fats and do not pose a serious health risk at normal intake. So in daily consumption, soybean oil is completely safe.
Second, when judging the quality of edible oil, we mainly pay attention to the content of fatty acids contained in it. The health of cooking oil cannot be judged simply by one oil. Because different edible oils contain different types and proportions of fatty acids, the health effects are also different. Fatty acids are divided into saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids. Animal oil is high in saturated fatty acids and cholesterol, and long-term consumption of large amounts may pose a threat to cardiovascular health. Vegetable oils, on the other hand, are rich in unsaturated fatty acids, such as oleic acid and linolenic acid, which are beneficial to health.
Third, let's look at the difference between animal oil and vegetable oil. Animal fats mainly include lard, butter, butter, etc., which can make ingredients more mellow when cooking. However, animal oil is high in cholesterol and saturated fatty acids, and long-term consumption of large amounts may increase the risk of cardiovascular disease. In contrast, vegetable oils are a healthier option. Vegetable oils contain a lot of polyunsaturated fatty acids, such as oleic acid, linolenic acid, etc., which are beneficial for cardiovascular health. Although vegetable oil is rich in vitamin E, it lacks vitamin K and A.
Therefore, when choosing cooking oil, we should try to use less animal oil and more vegetable oil. Vegetable oil contains more unsaturated fatty acids, which have certain health benefits. However, the nutrient content of different types of vegetable oils also varies, so the total intake should be controlled and the type of cooking oil should be changed appropriately to obtain a comprehensive nutrient intake. In normal times, it is recommended to change the type of cooking oil appropriately under the premise of controlling the total amount to ensure that the body can fully absorb the required nutrients.
Fourth, in daily life, for some special edible oils, there are three kinds of oils that need special attention, opening for more than 3 months, repeated frying and small workshop self-pressed oil, we should pay special attention. These oils pose health risks such as oxidation and excessive carcinogens. Oil that has been opened for a long time is prone to oxidation due to contact with oxygen in the air, and the content of microorganisms and mold may exceed the standard. Oil that has been fried repeatedly may contain carcinogens. However, small workshops self-press oil, there are problems such as raw material quality inspection, processing technology specifications, etc., which may contain harmful substances such as aflatoxin, which may have potential safety hazards. Therefore, when buying edible oil, we should pay attention to these problems when choosing edible oil, and should choose regular brands and avoid buying inferior oil.
There is no absolute answer to the question of which of the four common cooking oils, peanut oil, canola oil, olive oil, and soybean oil, which is the healthiest, and no one is the absolute best from a health perspective. Because different oils have different raw material sources, processing techniques, and quality, the composition and proportion are also different. To ensure a healthy diet, it is recommended that you rotate between different types of cooking oils to ensure that your body is getting the essential nutrients.
