Peanut oil, soybean oil, corn oil, melon oil are rich in essential fatty acids edible vegetable oil, as long as they are regular manufacturers, are safe and healthy cooking oil. It's important to note that the natural and unadulterated oils produced by small workshops are easily contaminated with aflatoxin due to the limitations of the production process, which can be detrimental to your health.

Corn oil, soybean oil, and sunflower oil are all cooking oils with more than 50% linoleic acid, and peanut oil has about 50% linoleic acid and 50% oleic acid in unsaturated fatty acids. These cooking oils are good for health, and moderate consumption can lower blood cholesterol, especially bad cholesterol, and increase good cholesterol. If you add flaxseed oil, which contains a-linolenic acid, and olive oil, which contains oleic acid, you have the perfect healthy cooking oil for your kitchen. However, although good oil is good, the daily intake of cooking oil per person should not exceed 25-30 grams. That's what the 2016 edition of the Dietary Guidelines suggests for cooking oil consumption.

Not all vegetable oils are healthy. Coconut oil and palm oil are vegetable oils, but they are rich in saturated fatty acids, which can increase bad cholesterol after consumption. Vegetable butter (margarine) is even richer in trans fatty acids, which are harmful to the cardiovascular system, and should be avoided as much as possible.

The question asked a little bit of a problem, of course, different raw materials also determines the taste and nutritional composition of each oil, but this is only established in the pressing process of production of edible oil. The production process of edible oil includes two kinds of pressing and leaching, and there is another kind of first pressing and then mixed with leaching oil. First of all, let's introduce the two production processes. The so-called pressing is to squeeze the oil from the raw material by purely physical methods, which is divided into cold pressing and hot pressing, of course, cold pressing will be better, and the pressing process is able to maximize the retention of the flavor and nutrition of the oil, but the disadvantage is that it has a low yield, for example, in the case of peanut oil, the yield of the oil from the pressing is about 35%. Leaching process is to use No. 6 light gasoline through the extraction process to dissolve the oil in the raw material, and then evaporate the light gasoline through high temperature, and then the rest of the oil will be refined, alkaline refining, deodorization and other processes to separate out the impurities in the oil, and the biggest advantage of the leaching process is that the oil yield is high, take peanut oil as an example, and the oil yield from the leaching process can be up to 47%, and the shortcomings of the leaching process are very obvious, the light gasoline residue in the oil, and benzopyrene produced by high temperature. The disadvantages of leaching are also obvious: the residual light gasoline in the oil and grease, the benzo(a)pyrene produced by high temperature, the residual chemical additives such as deacidification, etc., are potential threats to human health. In addition, leaching because of high temperature (up to 280 degrees Celsius) caused by the flavor components and nutrients in the oil and grease is basically destroyed, basically only pure oil and grease left, a heat. In addition, many of the labeled pressed peanut oil on the market is actually most of the combination of pressing and leaching, the first pressing and then from the pressed oil cake and then extract the remaining fats and oils, thereby reducing production costs, which is why a lot of labeled pressed peanut oil does not have the aroma of the peanut oil of the pure physical extraction of the rich, of course, there are manufacturers in order to add the appropriate flavorings in order to the aroma of the nose, which is hard to defeat the country, because we are Every producer is a chemist.

I would naturally say that peanut oil is the most healthy and nutritious and safe, because I personally experimented with peanut oil since I was a child and grew up eating peanut oil, and ate for more than 30 years, but still very much like the taste of peanut oil when I was a poor family, and sometimes directly on the steamed buns dipped in peanut oil to eat, with a little salt, really especially fragrant golden yellow peanut oil dripping on the head of the slow, sometimes accidentally flowed into the hands, so that the hands of my mother a taste of peanut oil taste, I should be beaten, and then I would have to go back to my mother.

The supermarkets have a wide range of cooking oils, from peanut oil, soybean oil, corn oil to melon oil, which is very confusing, and you don't know how to choose.

So, which cooking oil is healthier? What is the difference between them?

1, peanut oil

Peanut oil color is more bright and transparent, the aroma is very strong, which vitamin E and carotene and other nutrients to save more. In addition, the unsaturated fat in peanut oil contains more than 80% acid, and the fatty acid composition is very good, is considered a balanced vegetable oil, easy to digest and absorb.

Eating peanut oil can protect blood vessel walls, prevent blood clots, and prevent cardiovascular disease.

2, soybean oil

Soybean oil is generally darker in color, with a slight smell of beans, easy to produce foam when heated. The fatty acid ratio of soybean oil is better, and the digestive absorption rate in the human body can be as high as 98%. And the linoleic acid content in soybean oil is also very rich, which can reduce serum cholesterol and prevent cardiovascular disease.

3, corn oil

Corn oil consumption is not very common, this is because the oil rate of corn is not high, so a separate corn oil extraction is rare.

Corn oil is characterized by high levels of vitamin E. It is also rich in vitamin E, which is a key ingredient in the oil. In addition, corn oil is also rich in unsaturated fatty acids, linoleic acid content of more than 60%, can prevent atherosclerosis and other cardiovascular diseases, night blindness, dry eye disease and many other diseases.

In the case of corn germ oil, it is very suitable for quick cooking and frying food.

4, melon seed oil

Sunflower seed oil is golden yellow in color, clarified and transparent, fragrant, and contains a large amount of linoleic acid and other essential unsaturated fatty acids, can promote the regeneration and growth of human cells, to protect the health of the skin, and can reduce cholesterol in the bloodstream of the stagnant, is a kind of high-level nutritional oil.

As for the choice of cooking oil, you can choose according to your own habits, tastes and health needs.

The peanut oil, soybean oil, corn oil, and melon oil mentioned in the question are all safe and healthy as long as they are regular brands and properly preserved. But the real way to eat healthy oils is to eat them with care, not just a series of fats and oils.

Peanut oil, soybean oil, corn oil, melon oil, these oils are a "sector" of fats and oils.

The oils mentioned in the title are common in life. They are also the most common oils eaten on people's plates. Although these oils come from different oil crops, the essential fatty acids they provide to the body are mainly linoleic acid.

Although they are also essential fatty acids, but long-term in this "sector" to eat oil, can not meet the conditions of healthy eating oil. The reason for this is that you need to change your diet according to the different fatty acids. For example, home oil to contain essential fatty acids alpha-linolenic acid-based flaxseed oil, perilla oil, caraway seed oil, etc.; but also contains monounsaturated fatty acids-based olive oil, camellia oil, etc., and naturally, there is also the title of the linoleic acid-based oil.

So healthy eating oil, is to change the different "departments" to eat, and this different departments are in accordance with the different fatty acids to divide. Don't stick to one sector of oil.

Of course, another purpose of healthy eating oil is to eat less oil, the general population of the day the amount of oil is 25-30g.

Summarize, as long as the purchase of the oil is a regular brand of oil, you can rest assured that all the safety to eat. In order to eat healthy oil, you need to start from the angle of different fatty acids to eat different types, and to control the amount to eat, these two points are the guidelines for healthy eating oil.

A: safe or not, which depends on the conscience of the processing oil companies, corporate ethics, the conscience of the boss, pure or not, pure or not, pure or not, the content of how much, whether or not it is imported genetically modified raw materials production, genetically modified cooking oil whether or not not not yet by the current scientific and technological, unable to find, the body of the human body, causing harm to health, the human sexuality, the body of the human body. Health, causing harm to human sexual function, developmental function, reproductive function, etc., has not been discovered by modern science, causing harm to the human body harmful materials, ingredients, germs and so on!

Second: safe or not: to see the purity of the oil, the percentage, whether to add other vegetable oils, additives, chemical preservatives, kill, kill, disinfect and so on!

Third: trouble comes out of the mouth, disease enters by the mouth. Want to eat the safest imported food, oil, it is best to experience personally, personally buy raw materials, and then find a small visit to witness the processing into finished oil. Such oil is eaten healthy, assured, safe, at ease! I think.

To say the most safe and healthy peanut oil. It's higher in all nutrients.

The best process of pressing peanut oil, more popular choice.

The second should be corn oil, containing low cholesterol, relatively less fat, but it is not as fragrant as peanut oil, the nutrient content is slightly worse than peanut oil, but the price is not high.

Many people also like soybean oil, but some people feel that soybean oil, especially soybean salad oil, which has more ingredients, and other cooking oil ingredients, it is not very satisfied.

These oils are also left with peanut oil is not genetically modified, the other said safe are fooled GMO varieties who know the safety of not safe! Now imported more than 90 million tons of soybeans a year, which are genetically modified! Corn, not to mention the domestic previously pushed the first Yu 335, that can only be lol!

Which good really do not know, but years of experience in the restaurant industry told me that soybean oil should be the cheapest, genetically modified soybean oil is also the most, used several kinds of oil, the ingredient list inside are genetically modified soybeans! Friends peer, with the oil note is also genetically modified soybean oil, (the most common is that Yuanbao brand)

Peanut oil, melon seed oil, canola oil. Because of the low chance of buying genetically modified.
