Excuse me, what are the hazards of margarine (butter), namely shortening and hydrogenated vegetable oil? It exists in most bread and snacks. . .

There are many kinds of margarine and shortening, which can be divided into butter, hydrogenated vegetable oil and mixed oil (butter+hydrogenated oil) from the raw materials.

Among them, roasted oil with hydrogenated vegetable oil as raw material contains a lot of trans fatty acids, which will have adverse effects on human health if eaten for a long time.
