Background: Everyone knows that animal oil contains large quantities of saturated fatty acids and cholesterol, but really more healthy vegetable oils吗? More and more people have heard of many, vegetable oil, though good, as long as the words "hydrogenated" word than animal oils also bad. However, no hydrogenated oils, no animal oils, food production when the oil will be what to replace it? The most likely answer is palm oil. However, palm oil for health is good or bad then?
at the United States FDA food label requirements trans-fatty acids in the world, the people have to contain trans-fatty acids in hydrogenated vegetable oil abhor. Even McDonald's and other major Western-style fast food shops, also declared that they have put French fries, fried chicken oil block replaced by palm oil, no longer contain hydrogenated vegetable oils used for frying oil.
is not only fast food shops, in order to conform to the requirements of consumers, many food manufacturers have the original handy to use hydrogenated vegetable oil Products replaced by a natural palm oil. Price of palm oil because of lower thermal stability, and cooking fumes and carcinogenic substances produce less, the production of food when melted or crisp texture, color, beauty Mingyan Also, it has become the new darling of the food manufacturers.
palm oil, what are things? It is from the pulp of palm oil extracted, of which saturated fatty acids and mono-unsaturated fatty acids of about half and half. However, it and palm kernel oil and coconut oil is different saturation levels lower than that of the latter by 35%. Coconut oil are almost the highest content of saturated fatty acids, a natural oil than butter so it would also like to "hard." And palm oil at warm temperatures continue to be able to basically maintain the liquid. It is rich in carotene and tocotrienol (a natural vitamin E, biological activity than synthetic vitamin E high), nutritional value than animal fats high.
palm oil have a very good features, is that it can be "graded" processing. In other words, the oil after the physical treatment through a number of follow-up, you can put into the melting point of palm oil is not the same as several products. Some products focus on one of the palm oil fatty acid which, at room temperature more in semi-solid, and even solid-state; some products contain more unsaturated fatty acid, a liquid at room temperature. Liquid component of palm oil which contains a relatively large number of mono-unsaturated fatty acids and vitamin E, usually by adding a variety of调和油are used to balance the proportion of fatty acids.
one of those in semi-solid at room temperature and solid-state products, compare similar to lard, butter, butter status , it is being used to substitute for animal fats, hydrogenated vegetable oil alternatives, producing a variety of snacks, cookies, fried foods. The problem is that this kind of oil, carotene, vitamin E and mono-unsaturated fatty acids, such as wholesome ingredients have basically lost, and lard, butter compared to in fact did not have much advantage.
Japanese paid great attention to the healthy fats, do not support large-scale use in food hard palm oil, while our country is the palm oil and hydrogenated vegetable oil at the same time large-scale use, there is the proliferation of direct trend. Japanese are also worried about adequate, because palm oil which is rich in 16 carbon palmitic acid, and palmitic acid as a saturated fatty acids, the role of elevated blood lipids than lard 18 carbon stearic acid, and substantial intake when it will enhance the risk of heart disease, is a worrying issue.
in recent years, there is some animal studies and human studies confirm that pure palm oil for the control of blood lipids has a good impact, and olives Like oil can reduce "bad cholesterol" (LDL), increased "good cholesterol" (HDL) effects. This makes people feel at ease somewhat. While so, whether or not to eat palm oil problem, there is still a certain controversy in the academic community, as those of semi-solid and solid-state hard palm oil, palm oil and pure ingredients are not the same, is likely to no good for the heart.
In addition, we must caution those who read, "palm oil" in fact the use of hydrogenated palm oil products. Since palm oil and soybean oil, rapeseed oil, the hydride can also be carried out, becomes very hard (as illustrated), and produce some trans fatty acids. Hydrogenated palm oil is also very popular, they may hide in the ice cream in, it probably contains at substituting cocoa butter chocolate cocoa butter alternatives which serve as important role to meet the taste.
made a lot of environmentalists, eat palm oil, it means that the needs of tropical countries to produce more palm oil. This approach was also raised objections, because there is a large number of investigations have shown that palm oil production and lead to further destruction of tropical rain forests and the ecological environment deterioration.
So, what are we to eat what the oil does? Or eyes can see the fresh liquid vegetable oil is better. If possible, buy their own oil, to produce their own food, the safest and most healthy.
anyway, if we eat a little oil, eat less fat that contains a lot of snacks, desserts, cold drinks, snacks, pastries,起酥bread, puffing food and fried food, rain forests can be more damage from the heart will be more secure and less dangerous fat!
PS: look at this is "the most hard" palm oil.
this is the result of artificial hydrogenated palm oil.
