Which oil is the least healthy? Soybean oil? Reminder: These 4 kinds of oils should be eaten less or not

Edible oil is a must-have item in the kitchen, and it is also used by everyone in cooking every day, because behind every delicious dish, the participation of edible oil is inseparable, especially with the development of today's society, human With the improvement of living standards and quality, more and more people have begun to pay attention to the awareness of health preservation, so many people have also made great efforts in choosing edible oils.

US study: Soybean oil is the most unhealthy oil?

The claim that "soybean oil is the least healthy" stems from an animal study in the United States. The study designed 3 control groups to study the effects of soybean oil, fructose and coconut oil on obesity and other complications in mice.

Based on the results of the experiment, the researchers concluded that soybean oil was more likely to cause obesity and diabetes in mice than coconut oil and fructose, and had a greater potential impact on the liver.

As soon as the study came out, Dr. Joseph, the "famous doctor" in the United States, began to call on the public to stop eating soybean oil.

But is this conclusion really credible? Xiaojiu found that there are many strange things here.

First of all, the reason why this Dr. Joseph is famous is not because of his medical achievements, but because of his anti-vaccination and advocacy of "natural cures". He himself started a website selling health supplements and was repeatedly warned and punished by the FDA for false propaganda. During the COVID-19 outbreak, he also strongly opposed measures such as wearing masks, calling on people to use their own fake products. In August 2020, a number of agencies jointly called on the FDA and FTC to ban him from continuing false propaganda.

Second, there are multiple glaring loopholes in this study.

First, there is a huge difference between the four kinds of rat chow in the experiment and the normal rat chow. The rat food given to the mice in the experiment was very unhealthy, and it was specially designed to artificially make the mice sick.

Second, during the experiment, the researchers' records were contradictory. In the paper, there was no significant difference in the amount of rat food among the four experimental groups, but the accompanying data table showed that the mice in the soybean oil experimental group ate twice as much. This indirectly reflects the unreasonable experimental design, which has a greater impact on the results.

All in all, the experiment was "smartly" designed, and the conclusions appear to be contrived and cannot be applied to our normal diet.

Are these 4 really unhealthy oils?

1. Margarine

Margarine is a type of oil that contains trans fats, and excessive intake can lead to obesity and even cardiovascular disease. The British "Daily Telegraph" once published a study initiated by Canadian professor Susa, which analyzed 50 studies involving more than 1 million people and found that there is not enough evidence to prove that saturated fat is not good for health, but artificial Trans-unsaturated fats or trans fats in butter can increase the risk of death by 34%, of which the risk of death from coronary heart disease increases by 28% and cardiovascular disease increases by 21%.

2. Reusable oil

There are many families who pour a large amount of fried food into the pot when frying food, and it will be a pity to throw away the oil, so they will be collected again and reused, even if this method is also good for health. Bury some hidden dangers.

3. Palm Oil

The saturated fatty acid content in palm oil is very high, more than 50%. Excessive intake can easily make people fat, and it will also increase the cholesterol content in the body, increase the level of low-density lipoprotein, and easily induce high blood pressure, arteriosclerosis, etc. disease, so eat less.

4. Expired edible oil

Don't think that the edible oil will not expire. In fact, after the edible oil is opened for a long time, it will also deteriorate after the oxidation reaction with the air. After eating, there may be poisoning phenomena, such as nausea, vomiting, diarrhea, and abdominal pain.

For the sake of health, it is recommended that you try to avoid choosing these oils as much as possible, and do not end up with more complicated problems because of savings and other reasons, which will not be worth the loss.
