Some people usually pay special attention to health, adhere to a light diet in their daily lives, and even become vegetarians. They also take time to exercise and spend expensive money on some health care products. Some people even go to the museum of traditional Chinese medicine for massage and acupuncture. In short, they pay special attention to all aspects of daily life.
So why is soybean oil considered as the most unhealthy oil? Is soybean oil really the most unhealthy oil? Today, let's take a look at this problem together.

What oil is the most unhealthy? Is it soybean oil?
Soybean oil refers to the oil extracted from soybeans by pressing. Generally people will call it soybean salad oil, which is a very common edible oil. In some places, soybean oil is also called soybean oil, which refers to the edible oil made by squeezing soybeans.
Compared with other edible oil raw materials, the oil content of soybean is relatively low, only about 16%~24%.
In order to maximize the benefits, manufacturers usually use leaching method to obtain the oil in soybean when squeezing soybean oil, so the soybean oil we can see in the market is generally the finished product produced by leaching method.
Compared with other edible oils, soybean oil has a very obvious disadvantage, that is, the shelf life of soybean oil is relatively short, only one year's edible oil is yellow, and good quality soybean oil is pale yellow.
Through the transparent plastic bottle, it looks clear and transparent, with no sediment and no unpleasant smell of beans. When the temperature is below zero degrees Celsius, high-quality soybean oil will have oil crystals.
Soybean oil is rich in unsaturated fatty acids and linoleic acid. Proper consumption of soybean oil helps to regulate the levels of blood lipid and cholesterol, and also reduces the risk of cardiovascular and cerebrovascular diseases to some extent.
Soybean oil is also rich in soybean phospholipids, which is not available in other edible oils. This substance can promote the growth and development of brain nerves and blood vessels.
Soybean oil is rich in linoleic acid, linoleic acid, vitamin D and other nutrients, and it can also bring good dietotherapy and health care.
Since soybean oil is so good, why do many people think that soybean oil is the most unhealthy oil among many edible oils?
The reason why there is such a statement mainly comes from a report a few years ago, which repeatedly emphasized the harm of soybean oil to the body, arguing that eating soybean oil not only makes the body fat, but also increases the probability of diabetes, making children suffer from autism and making the elderly suffer from dementia.
The source of this report is not from people, but from an experiment with mice. The researchers studied mice with soybean oil with low fatty acid content and other high-fat foods for two years.
The final research results show that the mice that often eat soybean oil are abnormal, the cells in the body have died malignant, and oxytocin in the pituitary gland is obviously reduced.
After the report was published, many biologists put forward different views on it. Some biologists believe that this article is intended to guide public opinion, because soybean oil itself will not affect health, and the fatty acid content is not too much.
Even the World Health Organization has declared that soybean oil will not cause harm to the body, and everyone can use it normally. Moreover, the physique of us humans and mice is very different, so the statement that soybean is harmful to the body is a rumor. Don't believe it.

Reminder: Try not to eat these three oils.
hydrogenated vegetable oil
Hydrogenated vegetable oil is an artificial oil synthesized by adding hydrogen at a certain temperature and pressure with ordinary vegetable oil as raw material.
It is very common in our daily life, such as butter, margarine, creamer and cocoa butter.
In the process of hydrogenation of hydrogenated vegetable oil, some hydrogenated vegetable oil with insufficient hydrogenation will become trans fatty acid, which is easy to induce cardiovascular and cerebrovascular problems, so it is not recommended that you eat this oil often.
Self-squeezed peanut oil
In many places, some people especially like to eat self-squeezed peanut oil, and think that the food made from self-squeezed peanut oil is very fragrant. If the raw materials and environment for squeezing peanut oil are guaranteed, then self-squeezed peanut oil is very good, but self-squeezed peanut oil is not as healthy as we thought.
Because there are some small oil-squeezing workshops, the sanitary conditions are very poor, they look dirty, covered with cockroaches and dust, and some people will step on the raw materials with their feet. I don't know if the peanuts they used are moldy or bad.
Therefore, the sanitary conditions are not as good as we all think, and they are not necessarily healthy. It is not recommended that you often eat self-squeezed peanut oil.
Open cooking oil for too long.
Under normal circumstances, the shelf life of edible oil we bought in the market is about 18 months, but it can't be kept for 18 months after opening.
Because edible oil is easy to deteriorate after opening, if it takes more than three months to open, don't eat it, otherwise it will lead to food poisoning and even stomach trouble.
