For as long as I can remember, oil has been an indispensable ingredient in our lives. Cooking any dish, whether it is stir-frying, frying, roasting, you need to add the right amount of oil, otherwise it will not be complete. But why do we need cooking oil? In addition to this, the various oils we regularly use, such as peanut oil, soybean oil, rapeseed oil, olive oil and corn oil, which one is more beneficial to health and which one is the most potentially harmful, doctors have revealed this mystery for us.
Why do we need to add oil to cooking? We all know that adding the right amount of oil to the cooking process is necessary, but what is the reason for this? In fact, the vast majority of edible oils are fatty acids, which provide our bodies with the energy and metabolic substances they need, so edible oils are mainly for the intake of fatty acids. About 30% of the body's energy needs come from fat, and the fatty acids needed by the human body, such as linoleic acid, linolenic acid, etc., about 70% come from edible oil, and the human body cannot synthesize it by itself. In addition, edible oils provide fat-soluble vitamins A, D, K, etc., which are essential for promoting digestion and absorption and forming cell membranes. Some of the ingredients in cooking oil are also very beneficial to the human body.
The first is saturated fatty acids, which provide a stable structure for the body and organs, slow down vibration, and constitute the main component of cell membranes. In addition, saturated fatty acids also help the body absorb fat-soluble vitamins. Monounsaturated fatty acids, such as oleic acid, help maintain cell membrane permeability, regulate cholesterol levels, improve blood status, enhance memory, and promote brain function. Polyunsaturated fatty acids prevent cardiovascular and cerebrovascular diseases, improve brain function and protect vision. Cooking oil also contains many other wholesome ingredients, some of which the body cannot synthesize. Therefore, a moderate amount of edible oil is beneficial to the body, but not excessive, after all, oil is mainly fat, excessive intake has adverse effects on health.
However, there has been a recent controversy over soybean oil. At one time, soybean oil was considered a healthy cooking oil with nutritional benefits. It is rich in vitamins, lecithin and minerals, which have laxative and digestive effects. But why is there so little mention of soybean oil now?
Studies conducted by some internationally renowned research institutions have found that soybean oil is perhaps one of the most unhealthy cooking oils. In their experiments, they divided mice into three groups and fed foods such as soybean oil, coconut oil and fructose, and found that mice that consumed soybean oil had the highest rates of obesity and experienced many metabolic problems, including severe liver damage. Scientists believe that soybean oil may be harmful to the liver and increase the risk of obesity. Further research also found that soybean oil contains more fat, including unhealthy fatty acids, than other vegetable oils. In addition, at high temperatures, a substance in soybean oil breaks down into trans fatty acids, which is one of the important causes of various chronic diseases such as high blood pressure, atherosclerosis, and myocardial infarction. There is also a substance that oxidizes at high temperatures, which may increase the risk of cell inflammation, which has been shown to be one of the important factors that cause cancer. Therefore, the health of soybean oil has been questioned.
So which of the peanut oil, canola oil, olive oil and corn oil is better to eat? Each oil has its own characteristics and potential benefits. Peanut oil is popular for its rich aroma and high content of unsaturated fatty acids, but it is important to pay attention to quality to avoid food poisoning. Canola oil is rich in unsaturated fatty acids, vitamins, and minerals, but some of these fatty acids may be detrimental to vascular health. Olive oil is advertised as a healthy cooking oil, but it is not resistant to high temperatures and is suitable for low-temperature cooking or cold dressing. As for corn oil, it is rich in vitamins and minerals that help lower cholesterol and prevent cardiovascular and cerebrovascular diseases, but it is also prone to spoilage, so quality is also important.
However, no single cooking oil is perfect. There is no such thing as absolute perfection in this world, and balance is the basic principle of this world. Moderate consumption of a variety of different oils may be more wholesome, which can help compensate for the deficiencies of various oils and reduce the potential harm of a single oil.
The dietary guidelines for Chinese residents recommend that each person should not eat more than 30 grams of fat per day, and the optimal range is 25-30 grams. Therefore, when cooking, we should pay attention to reducing the amount of cooking oil in moderation. Only a small amount of cooking oil needs to be added to each dish, usually 25-30 grams is enough. At the same time, don't be overly convinced that vegetable oils are necessarily healthier than animal oils, as there is no clear evidence for this. Different types of oils have the potential to have health effects, and the key is to choose the right oil and maintain the right amount.
In summary, a healthy diet may include a combination of many different oils to achieve a comprehensive nutritional intake and reduce potential health risks.
