In addition, there was just half a barrel of soybean oil at home that had not been used up, and the more Aunt Chen thought about it, the more scared she became, and finally decided to throw the oil away.
After listening to it, I thought Aunt Chen was so cute, and I told him that soybean oil is actually relatively healthy, and told her not to listen to the rumors.
As a doctor, today I will take you to understand "oil", what effects oil has on our body, how to eat oil correctly and what oil should not be eaten.
1. Is GMO soybean oil really harmful and carcinogenic?
In fact, this question has been answered by many experts and data. You see, the European Union, the United States, and our country import a large amount of genetically modified soybeans every year, if it is really harmful, how can these countries dare to import it?
Our country's Farmer's Daily also refuted the rumors, saying that approved genetically modified soybeans are as safe as non-genetically modified soybeans.
Soybean oil is the second largest edible oil in the world, and many countries have been eating it, including developed countries such as Europe, the United States and Japan, and have been eating it for more than 20 years. After so many years, I haven't seen any country say that eating genetically modified soybean oil caused health problems.
Most of the people in our country have eaten genetically modified foods, because the soybeans we import are basically genetically modified.
Even if you haven't eaten GM soybeans directly, you've certainly eaten livestock fed with GM soybeans, foods processed with GM soybeans, or fried with GM soybean oil in restaurants.
If you're still not sure, you can also opt for non-GMO cooking oil. In short, believe in science and don't believe rumors.
2. What are the nutritional values of edible oil?
1, Fatty acids
These include both saturated and unsaturated fatty acids. Saturated fatty acids are like one of the energy sources that our body needs, but we can't eat too much, otherwise we will easily gain weight.
Unsaturated fatty acids are divided into monounsaturated fatty acids and polyunsaturated fatty acids, which are particularly good for our body, especially linoleic acid and α-linolenic acid, which are necessary for our body, and it is not possible to do without them.
2. Fat-soluble vitamins
Like vitamins E, A, D, and K, these vitamins have a great protective effect on our body.
For example, vitamin E is an antioxidant that can help our body resist oxidative damage;
Vitamin A is good for our eyesight, while vitamins D and K are especially important for bone health.
3. Micronutrients
Although the content is not much, it has a lot of effects. For example, squalene, polyphenols, phytosterols and other things, they can help us lower cholesterol, promote metabolism, and have many benefits for the body.
Different cooking oils have different nutrients.
For example, rapeseed oil, which contains rapeseed polyphenols, which is good for lowering blood sugar;
The olive polyphenols contained in olive oil have a certain positive effect on diseases such as hyperlipidemia;
Sesame oil contains sesame lignans, flaxseed oil contains flax lignans, rice bran oil contains gamma oryzanol and so on.
When choosing edible oil, you can choose different kinds of oil according to your needs and preferences.
Third, these 4 kinds of oils may be carcinogenic, try to eat less or not eat
1. Trans fatty acids
Those foods that look particularly tempting, for example, actually have something called trans fatty acids hidden in them.
These fatty acids are not only difficult for the body to digest, but also accumulate in our bodies, increasing the risk of chronic diseases such as heart disease, high blood pressure and diabetes.
2. Palm oil
It is extracted from a plant called oil palm, which is found in many processed foods, such as instant noodles, puffed foods, and those puff pastry snacks.
However, recently, a well-known international magazine "Nature" published a research report.
The study was done by scientists in Barcelona, Spain, who experimented on animals and found that palm oil could make mouth cancer more likely to spread.
3. Oil that has been opened for more than 3 months
Even if the edible oil has not expired after opening, it cannot be eaten casually after a long time.
Some people think that as long as the expiration date is not reached, it will be fine, but this is not the case. Oil that has been opened for more than three months is susceptible to mold contamination and may react with oxygen in the air to form undesirable substances.
4. Fry the oil repeatedly
Some families are more frugal and think that they eat it by their own people anyway, and it doesn't matter how many times they use the oil. This kind of oil, after frying a few times, may produce carcinogens such as benzopyrene, acrylamide, and heterocyclic amines, which are really bad for the body if eaten for a long time.
In addition, repeatedly heated oil will also produce a large amount of trans fatty acids, which is an accomplice to cardiovascular and cerebrovascular diseases.
Fourth, the precautions for using oil in life
When cooking, we have to pay attention to the use of oil.
Don't let the oil warm too high, and don't use the same batch of oil over and over again for frying.
If you really need to heat the oil, you have to control the heat so that the oil doesn't burn.
Of course, we can also choose some healthier cooking methods, such as steaming, boiling, stewing, etc., so that we can use less oil and are good for the body.
In addition, the storage of oil is also important. If it is not stored well, the oil can easily deteriorate and produce harmful substances. We should keep the oil in a cool and ventilated place and do not let direct sunlight and high temperatures bake it.
The used oil should also be put away in time, and don't let it be in contact with the air for too long to avoid spoilage.
