Many people think that vegetable oil is good for health.
Perhaps because they saw the name of the oil as "plant."
I mean, plants good for health. So, oil so are plants.
Even mainstream nutritionists suggest that we use vegetable oils, because according to them, unsaturated fats are much healthier than saturated fats.
However, many studies have shown that these oils can also cause serious problems .
The composition of fatty acids in vegetable oils differs from all the substances we have seen in evolution.
This leads to the in the body and contribute to many diseases.
Here are 6 reasons why vegetable oil can be harmful to health.
1. Vegetable oil in large quantities is "unnatural"
In this article, I refer to processed seed oils such as soybean oil, sunflower oil, corn oil, canola oil, cottonseed oil, safflower oil and a few others.
Although they are not really vegetables, these oils are still called "vegetable oils" (also called vegetable oils).
These oils contain so many, so much Biologically active fats are called polyunsaturated fatty acids If it absorbs too much, it will be harmful.
People have been developing for a long time, but the food processing industry has just emerged.
We have just started producing vegetable oil in the last 100 years.
In 1909 and 1999, the consumption of soybean oil increased thousands of times and it currently supplies 7% of calories in the US diet .
This is about industrial rapeseed oil production process:
This method of processing is really terrible including pressing, heating, using a lot of industrial chemicals and extremely toxic solvents. Other vegetable oils are also processed in the same way.
Anyone who thinks such things can be used as human food makes me immensely shocked .
If you choose healthier brands that are cold-pressed (less expensive and therefore more expensive) then the processing method will be much less terrible, but the problem with too much Omega-6 is still there.
Conclude: Because in ancient times we did not have enough technology to treat vegetable oil, so until human society had significant development, we have the opportunity to use this product.
2. Vegetable oil reverses the fatty acid composition of cells in the body
There are two types of fatty acids that are considered "essential" - because the body cannot produce them themselves.
They are Omega-3 and Omega-6 fatty acids.
Humans must supplement these substances from the diet, but they are right loaded with balanced doses.
In the process of human evolution, the Omega-6 ratio: Omega-3 can be in the range of 4: 1 to 1: 2.
Today, this rate is at an average of 16: 1, and this ratio is different for each person .
These fatty acids are not only immutable structural molecules or fuel for the mitochondria of cells, they also take charge of important function affect different systems like the immune system .
When the balance between Omega-6 and Omega-3 is lost in the cell, the situation becomes extremely bad.
Another problem is that these fatty acids are unsaturated. Polyunsaturated fats have two or more double bonds, while monounsaturated fats have a double bond and saturated fat has no double bonds.
The more fatty acids that have double bonds, the more reactions there are. The polyunsaturated fat with oxygen, causes chain reactions, destroys other structures and can even destroy important structures like DNA .
These fatty acids are located in the cell membrane, increasing the harmful oxidation chain reaction.
According to this graph, fat storage is like (the most popular Omega-6 fat) has Tripled in the past 50 years.
Photos from: .
Yes, excessive consumption of vegetable oils results in a real structural change in our fat and cell membrane storage.
I don't know about you, but I really feel scared.
Conclude: Omega-6 and Omega-3 are bioactive fats. Our bodies need these substances in a balanced amount to work optimally. Too much Omega-6 in the cell membrane can cause harmful chain reactions.
3. Vegetable oil contributes to inflammation
Fatty acids Omega-3 and Omega-6 are used to make substances called in the body.
These are modified fatty acids located in the cell membrane.
They play an important role in body activities such as intracellular transmission, immunity and inflammation.
If you have ever taken aspirin or ibuprofen and found pain to be relieved, it is because these drugs inhibit eicosanoid pathways and reduce inflammation.
Acute inflammation is a beneficial condition that helps the body recover from injury (like when you step on a lego piece), but a chronic inflammation of the body is extremely danger.
In general, Omega-6 eicosanoid is an inflammatory substance, while Omega-3-derived substances are anti-inflammatory .
Different fatty acids fight each other. The more Omega-6 your body has, the more Omega-3 you need. Conversely, if you consume less Omega-6, you do not need to take more Omega-3 .
High levels of Omega-6 and low Omega-3 are the worst cases, but this is only the case for people who follow Western diets.
Simply put, a diet rich in Omega-6 but low in Omega-3 contributes to inflammation. A balanced diet of Omega-6 and Omega-3 helps reduce inflammation .
Currently inflammation is given n cause serious diseases like cardiovascular disease, arthritis, depression and even cancer.
Conclude: Eicosanoid is the signaling molecule currently produced by Omega-6 and Omega-3 fats, which are important in regulating inflammation in the body. The more you absorb Omega-6, the higher your risk of systemic inflammation.
4. Vegetable oil is high in trans fat
Trans fats are unsaturated fats that can be converted to solid at room temperature.
These fats are very toxic and can cause diseases such as cardiovascular disease, cancer, diabetes and obesity .
Fat is so harmful that governments around the world have begun to enact legislation that requires food manufacturers to lower their trans fat content.
However, a little-known fact is that vegetable oils often contain a large amount Trans fat.
In a study of soybean oil and canola oil sold in the US, about 0.56% to 4.2% Fatty acids in these oils are toxic trans fat .
If you want to limit your intake of trans fat (so), you should not only avoid eating common sources of trans fat like biscuits and processed baked goods, you also need to avoid eat vegetable oil.
Conclude: Trans fat is highly toxic and can cause many diseases. Soy oil and canola oil are widely sold in the United States and contain a lot of trans fat.
5. Vegetable oil may increase the risk of cardiovascular disease significantly
Cardiovascular disease is the leading cause of death in the world .
Although saturated fat has been considered a major cause of disease, recent studies show that they are harmless .
Now the attention is focused on vegetable oil.
Many randomized controlled trials have examined the effects of vegetable oil on cardiovascular disease.
3 studies have found that vegetable oil makes the risk of disease significantly increased , while 4 studies did not detect significant impacts based on statistics .
Only one study found an effect against cardiovascular disease, but this study has made some errors .
If you look at observational studies, you will see a very large correlation.
This chart is from a study of the relationship between blood levels of Omega-6 and the risk of death from cardiovascular disease :
You can see that the United States is in the highest position on the right, with the highest amount of Omega-6 and the risk of death from cardiovascular disease.
Although this study only points out each relationship, it reinforces the idea that inflammation is one of the causes.
I really want to show you some studies that show that polyunsaturated fat reduces the risk of cardiovascular disease. But the problem is that these studies have not shown any difference between Omega-3 and Omega-6, this very important .
When conducting the experiment, the researchers found that Omega-6 actually increased the risk, while Omega-3 was effective against the disease .
Conclude: Evidence from both randomized controlled trials and observational studies has shown that vegetable oil may increase the risk of cardiovascular disease.
6. Consumption of vegetable oil can cause many other diseases
Because unsaturated fats are intimately involved in the body's activities at the molecular level, that means they can also affect other diseases.
Most of these effects have not been well studied in humans, but there have been observational studies and animal studies showing that vegetable oils can cause other serious diseases:
In one study, high levels of Omega-6 breast milk were associated with asthma and eczema in young children .
Studies in both animals and humans indicate a large intake of Omega-6 can cause cancer .
Another study shows the link between vegetable oil consumption and mortality .
Omega-6 ratio: Blood Omega-3 has been shown to be closely related to the risk of severe depression .
This is just the tip of the iceberg. Inflammation and consumption of vegetable oils are linked to a range of serious diseases that are beyond the scope of the article.
Myself believe Vegetable oil (along with other types sugar additive and refined wheat are the main causes of chronic diseases of Westerners, which are currently the most worrisome health problem.
Things to remember
If you want to have a healthy body and reduce the risk of serious diseases, you should consider removing vegetable oil from your diet.
