1869, French emperor Charles Louis Napolé on Bonaparte (Louis Na Ba) ordered a tender to "develop butter substitutes for navy and low-income people". Only the chemist H. Meige-Mauriere participated in the tender. In fact, Mauriere had studied the nutritional value of animal fat for seven years before this. Butter is a light yellow solid oil extracted from milk or cream, which is a daily food for French people. However, due to France's external launch year after year, social unrest and declining output, not only many ordinary people can't afford butter, but even many cows are malnourished because of lack of forage. In his research, Mauriere found it difficult to extract cream and butter from the milk produced by lean cows. He thinks butter is the fat of cattle. So he melted butter to extract fat, and added skim milk, sodium bicarbonate and so on. The world's first margarine was made by mixing, stirring and pressure molding. Morille obtained the invention patent of margarine on July 5th, 1869. Because yellow milk flows like pearls in the process of synthesizing margarine, Moliere borrowed the Greek word "margaron" and named his invention "Gil Michaels".
1870, just before the margarine factory was completed and put into production, the Franco-Prussian War broke out. In less than two months, the French army was defeated and Louis Na Ba stepped down. At this time, the shrewd Dutch butter merchant bought the manufacturing right of margarine. 187 1 set up a factory to produce the first batch of margarine in the world.
Butter is a high-quality food ingredient, but it is expensive. In many processed foods, hydrogenated vegetable oil (that is, margarine) is used to replace natural butter. This margarine contains a trans fatty acid, which has a very bad influence on human health.
Trans fatty acids are harmful to health in many ways, including the following aspects:
First, increase blood viscosity and cohesion, and promote thrombosis; At the same time, it can also increase the low-density lipoprotein LDL (bad lipoprotein) and decrease the high-density lipoprotein HDL (good lipoprotein) in human blood, and promote the occurrence of arteriosclerosis and type II diabetes. For infants and young children, trans fatty acids will also affect their growth and development, and have a negative impact on the development of the central nervous system.
The results of "Nurses' Health Survey", a large-scale nutrition research in the United States, also prove that the higher the intake of trans fatty acids, the greater the risk of heart disease. Therefore, American nutritionists have long warned that people should try to eat less foods containing trans fatty acids.
Many children like eating in fast food restaurants very much, which will not only lead to obesity, but also bring many adverse effects on the development of internal organs. According to media reports, maternal consumption of foods rich in trans fatty acids may even cause harm to the health of babies.

Pay attention to the instructions on the package when buying food. As long as you see the words "vegetable creamer", "non-creamer", "shortening" and "margarine" on the ingredient list, it means that the good taste of the product comes from margarine, and the product contains trans fatty acids, so you should consider it carefully when buying.
