Is the rumor that self-pressed oil causes cancer?

Because self-pressed oil has no refining step, it does contain more nutrients than the oil sold on the market. But in my opinion, this may also be the most intuitive and deceiving place. Another thing that attracts ordinary consumers is the gimmick that it does not contain preservatives. However, it is claimed that food without preservatives is basically not purchased. Merchants usually use the psychology of consumers to talk about "adding" color changes to create gimmick marketing.

I will explain the advantages and disadvantages of self-pressing oil from three aspects.

First of all, from the initial selection of raw materials, the raw materials such as peanuts purchased by consumers cannot ensure that there is no deterioration to produce aflatoxin. At the same time, if the oil extraction machine used is not properly stored and cleaned, it will also breed a lot of bacteria. Therefore, there are many safety risks from the very beginning of oil extraction.

Secondly, in the unrefined self-pressed oil, there are many small molecular impurities, so its "smoke point" is low during heating, and it is easy to produce oil fume, and oil fume contains many harmful substances, which are harmful to people's eyes and respiratory tract. Form irritation, endanger human health.

Finally, let's talk about the preservation of self-pressed oil. It is precisely because self-pressed oil contains more nutrients and impurities, so it is easier to deteriorate than ordinary oils. If no preservatives are added and the storage conditions at home are not very qualified, the deterioration of oils will cause greater damage to the human body. harm.

Therefore, from a safety point of view, it is recommended that you buy edible oil with guaranteed quality in supermarkets, and some nutrients in self-pressed oil can be obtained by eating some nuts or other foods.

Of course, if you have a special preference for self-extracting oil, try to buy high-quality raw materials in small amounts each time, and eat them as you press them, and ensure the hygiene of the oil extraction process, but the cost is higher.

As for carcinogenicity, it is not that the oil is extracted to cause cancer, but the aflatoxins and impurities produced by deterioration may have carcinogenic effects.
