"Mom, how is this oil so black!"
"As long as you can eat it, I go to the village to freshly squeeze it, why do you care so much?"
Since Aunt Chen saw on the Internet that many edible oils were found to be unqualified, she has been insisting on eating self-pressed oil, feeling safe and assured.
The safety of edible oil has always been a hot issue of concern to the people. In recent years, the claim that edible oil contains carcinogens and cannot be eaten has also aroused concerns among many consumers.
So, why does eating cooking oil cause cancer? #文章首发挑战赛#
1. How harmful is it to the body after eating substandard oil?
The reason why there are rumors of Rayser is because in some news in previous years, it has been reported many times that many batches of edible oil have been found to be unqualified in random inspections. Among them, a batch of aflatoxin was detected to exceed the standard by 12 times, or there were problems of benzopyrene and rancidity exceeding the standard, so many people were panicked.
The most common reason for failure in sampling is the content of aflatoxin B1, which is commonly found in moldy foods, and peanuts, corn, and rice are all easily contaminated. If the raw materials used for oil extraction are not well controlled, aflatoxin will also be present in the oil extracted.
There is also the problem of excessive benzopyrene, which is listed as a class I carcinogen by WHO, and long-term exposure will increase the risk of liver cancer, lung cancer, colon cancer and other cancers.
In addition, there may be contamination in the production process, such as soil and water pollution in the process of raw material planting, and loopholes in the process and equipment in the oil processing process
When buying oil daily, you must choose a regular brand, so as not to buy problematic products and bring unnecessary risks to your health after eating.
2. Soybean oil is the most unhealthy oil, more terrible than sugar, can you believe it?
According to an article widely circulated on the Internet, a famous American doctor clearly pointed out that soybean oil is the most unhealthy oil, and long-term intake is not good for health, and it brings even more harm than sugar.
In fact, this so-called famous doctor is very notorious in the United States, and he has been warned many times by the US FDA for opposing genetically modified organisms, advocating "natural health", false propaganda, etc., and has also been punished many times. Moreover, the so-called research cited in the article was conducted on mice, and the results obtained could not be directly applied to the human body, so there was no reference significance.
It is undeniable that there are trans fats in soybean oil that are not good for health, but we can't talk about toxicity regardless of dosage, there are about 0.533g of trans fatty acids in 100g of soybean oil. According to the existing recommendation, the daily intake of trans fatty acids should be less than 1% of total calories, and the daily intake of trans fatty acids should be limited to 2 g based on 2000 kcal per day. If we consume 30g of soybean oil per day, we will only consume less than 0.2g of trans fatty acids, which is in line with the recommended intake.
In addition to trans fatty acids, soybean oil also contains more polyunsaturated fatty acids, which are beneficial to health.
3. Reminder: These 4 oils should really be eaten less
In life, we still have to pay attention to selective edible oil, and it is recommended not to eat these oils.
1. The small workshop squeezes its own oil
The hygiene of small workshops cannot be effectively supervised and can be contaminated during production. In addition, the raw materials cannot be strictly screened, and the oil squeezed out may have pollution problems.
2. Repeatedly used oil
Substances such as benzopyrene, heterocyclic amines and acrylamide will be produced in the oil and oil that is used repeatedly, and the inside will be contaminated with food residues and microorganisms. The content of trans fatty acids in fats and fats will also increase significantly, which is not good for health after consumption, and it is easy to gain weight.
3. Oil that has been opened for more than 3 months
Oils that have been opened for more than 3 months will have serious oxidative rancidity, and long-term ingestion is likely to lead to food poisoning in the body, manifested as nausea, vomiting, diarrhea, etc., and will also increase the burden on the liver and kidneys.
4. Oil with hala flavor
The appearance of haha flavor of oil indicates that it has rancidity, and it should be discarded in time to avoid affecting health after eating.
4. How to eat edible oil to be the healthiest?
Oil is indispensable for our health, but these few things are important to learn to eat healthy oil.
1. Look at the quality grade when purchasing
When buying cooking oil, pay attention to the grade, not that the higher the grade, the better the quality.
Grade 1.2 has high purity, less impurities, and the nutrients in it are lost, which is more suitable for high-temperature stir-frying and frying, while grade 3.4 has low purity and many impurities, but retains more nutrients, and is more suitable for low-temperature cooking.
2. Control total intake
The dietary guidelines recommend that the daily fat intake is 25~30g, and the use of frying and frying should be reduced when cooking, and you can choose steaming, stewing, stewing, and other methods with less oil.
