In the period when all kinds of edible oils are on the market, many people feel that soybean oil is not healthy. As an edible oil that most families will use, is soybean oil really as bad as everyone thinks?

What oil is the most unhealthy? Is it soybean oil?
As its name implies, soybean oil is an edible oil extracted directly from soybean, also known as soybean salad oil, and it is one of the most common vegetable oils for cooking food.
Soybean oil contains a variety of nutrients beneficial to the body, including 1%~3% phospholipids, 5%~8% sterols and a small amount of protein. A small amount of soybean oil can enhance physical fitness and replenish sufficient energy for the body.
The statement that soybean oil is the most unhealthy originated from an animal study in the United States, which involved three groups of controls to study the effects of soybean oil, fructose and coconut oil on obesity and other complications in mice.
According to the experimental results, the researchers concluded that soybean oil is more likely to lead to obesity and diabetes in mice than coconut oil and fructose, and has a greater potential impact on the liver.
Soybean oil will enter the vicinity of the human throat through the mouth with other foods, and finally reach the stomach. After entering the stomach, it can accelerate the function of gastrointestinal peristalsis and digestion, and improve the digestion and absorption ability of the stomach. The linoleic acid rich in soybean oil can also play a role in relaxing bowels and effectively improve constipation.
German research experts also made relevant research in 2004 on whether soybean oil is good for health.
The researchers divided 20 white rabbits into two groups, one group ate food containing soybean oil for a week, and the other group ate other oily foods for a week.
After a period of comparison, it was found that the white rabbits who ate soybean oil had abnormal physical changes, while the white rabbits who used other edible oils were still in good physical condition, from which it was concluded that the use of soybean oil would indeed do harm to their bodies.
However, once this statement was published, it was unanimously denounced by many netizens. They felt that the physical condition and structure of the white rabbit were fundamentally different from those of people. It could not be confirmed by a certain conclusion, but there is no doubt that excessive intake of soybean oil will definitely do harm to the body and also damage cardiovascular health. For the sake of your health, please control the intake of edible oil and reduce the damage to your body.

Reminder: Try to eat less of these two oils.
1 species: small workshops make their own oil extraction.
Although the current living standard has been improved, most people still maintain the concept of thrift. In order to save money, the elderly in rural areas will go to small workshops to squeeze oil for food.
Self-pressed oil is a kind of oil made by physical pressing, which will produce a lot of smoke when cooking. All the raw materials used in self-pressed oil are rotten and moldy nuts and various cereals, and more aflatoxin will be produced in the rotten food. This kind of substance has been listed as a first-class carcinogen by the World Health Organization as early as 1993, and it is a highly toxic substance with strong toxicity. The toxicity of aflatoxin is 68% of that of arsenic.
Eating self-squeezed oil with strong toxicity often seriously affects your health, and it can also induce liver cases. Many self-squeezed oils produced by small workshops not only contain toxins, but also have poor hygiene conditions. It is best to eat less for health.
Type 2: oils containing trans fatty acids.
Trans fatty acids, also known as trans fats, can be found in many foods, such as margarine and margarine. This fried food also contains more trans fatty acids.
Trans fatty acids are not easy to be digested and absorbed by human body. Long-term intake of trans fatty acids will accumulate in the stomach and tissues of human body, which is easy to induce hyperlipidemia. The flow of blood makes blood thicken, the flow speed slows down, and the problem of blood vessel blockage is easy to occur.
According to the statistics of the World Health Organization, about 540,000 deaths worldwide are related to trans fatty acids. The mortality rate of foods containing trans fatty acids increases by 34% and the cardiovascular morbidity rate increases by 45%.
Excessive use of edible oil containing trans fatty acids will also lead to abnormal secretion of hormones in men and ovulation disorder in women, indirectly causing infertility and affecting future fertility.
For the sake of health, before buying edible oil, be sure to observe whether the edible oil contains trans fatty acids.

How to eat edible oil to be healthy?
(1) control intake
According to the "Chinese Dietary Guidelines", the daily intake of edible oil for adults should be controlled at about 25-30g. Excessive intake will increase the concentration of cholesterol and triglyceride in blood vessels, which will have adverse effects on health and easily induce obesity, hypertension, hyperlipidemia, hyperglycemia, diabetes and cardiovascular and cerebrovascular diseases. Before this, we must control the daily intake, and never eat too much.
(2) Flexible choice
Don't just eat a single kind of cooking oil, you can eat a variety of cooking oils, and choose the right oil for different cooking methods.
For example:
You can choose corn oil, soybean oil and sunflower seed oil when stewing food.
You can choose peanut oil, mustard oil, almond oil and pumpkin seed oil when cooking.
You can choose olive oil and rapeseed oil when cold food.
(3) Choose edible oil in small bottles
Edible oil is also edible oil that has a certain shelf life and has been placed at room temperature for a long time. If the bottle cap cannot be tightened in time and it is in direct contact with sunlight for a long time, it will make edible oil moldy and deteriorate, breed more aflatoxins, and bring great threats and influences to health.
When buying cooking oil, try to choose small bottles of cooking oil, eat it in a short time, and avoid long-term contact with the air to avoid mildew and deterioration of cooking oil.
