Extended data:
Among food, there are two kinds that deserve special attention, that is, fried food and baked food. Crisp, crisp, fragrant and soft are their fatal temptations.
The attraction of these two foods is largely due to the large amount of fat that makes them crispy and delicious. However, the oil used in it is often harmful to health. It contains not only trans fatty acids, but also a lot of saturated fatty acids. There are also toxic substances produced by oxidative polymerization and cyclization of fats in frying oil.
Fat is a part of human building materials. Human cells are constantly updated, and the fat used for renewal and repair comes from the dietary fat eaten every day. As you can imagine, if inferior materials are used in the construction, the quality of the house will be very poor, and cracks will leak or even collapse sooner or later.
But what about our bodies? If you always use the wrong fat as a material, it will inevitably leave serious hidden dangers to your body. So although it is not a poison, long-term consumption of trans fats will make people collapse. Therefore, people have reason to stay away from it as much as possible.
