margarine, also known as margarine, is a substitute food for butter or cream made from one or more animal fats.

in p>1869, the French emperor Napoleon iii (Louis nabar) ordered a tender for "developing butter substitutes for the navy and low-income people". And only the chemist H. Meige-Mauriere participated in this tender. In fact, before this, Mauriere had studied the nutritional value of animal fat for seven years. Butter is a light yellow solid oil extracted from milk or cream, which is a daily food for French people. However, due to the external launch of France year after year, social unrest and production decline, not only many ordinary people could not afford butter, but even many cows were malnourished due to lack of forage. In his research, Mauriere found that it is difficult to extract cream and butter from the milk produced by lean cows. He thought that butter was the fat from cows. So he melted beef tallow to extract fat, added skim milk, sodium bicarbonate, etc., mixed and stirred, and pressure-formed, which made the world's first margarine. Mauriere obtained the invention patent of margarine on July 15th, 1869. Because yellow milk flows like pearls in the process of synthesizing margarine, Mauriere borrowed the Greek word "margaron" to name his invention "Maiqilin".

In p>187, just before the margarine factory was built and put into production, the Prussian-French War broke out. In less than two months, the French army was defeated and Louis Naba stepped down. At this time, the shrewd Dutch butter merchant bought the manufacturing right of margarine. Established a factory in 1871 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, and there is a trans fatty acid in this margarine, which has a very bad influence on human health.

Trans fatty acids are harmful to health in many aspects, including the following aspects:

First, it increases blood viscosity and cohesion, and promotes thrombosis; At the same time, it can also increase the low-density lipoprotein LDL (that is, "bad lipoprotein") in human blood, reduce the content of high-density lipoprotein HDL (that is, "good lipoprotein"), 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 a large-scale nutrition research "Nurses' Health Survey" 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 already issued a warning, suggesting that people should eat as little food containing trans fatty acids as possible.

Many children like eating food 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" written on the ingredient list, it means that the good taste of the product comes from margarine.
