2. Vegetable butter is also called hydrogenated vegetable oil or trans fatty acid or margarine. It is the product of hydrogenation catalysis of ordinary vegetable oil at a certain temperature and pressure (also the synthesis of chemical products and flavors). Because it can not only prolong the shelf life, but also make the cake more crisp; At the same time, it is widely used in food processing because of its high melting point and solid shape at room temperature.

3. Hydrogenation makes vegetable oil more saturated. Or converting cis fatty acids into trans fatty acids. This oil is found in most western cakes and biscuits. The structure of hydrogenated vegetable oil is chemically trans-bonded, which is hundreds of times more toxic than real cream. Recent research shows that trans fatty acids are more harmful to human body than saturated fatty acids.

4. Every 2% increase in trans fatty acids in the diet will increase the risk of cardiovascular and cerebrovascular diseases by 25%. Other experiments have found that trans fatty acids may lead to Alzheimer's disease. Time magazine once published that hydrogenated vegetable oil does not exist in nature, which means that under natural circumstances, the human body cannot absorb and digest this oil. After eating, it will cause damage to the liver, and then destroy the human cell membrane, resulting in cell defects, affecting cell replication and regeneration in the future. Long-term and large-scale use will cause premature aging symptoms.

5. There is no clear standard for the use of hydrogenated vegetable oil in China. If the ingredients list is marked with the words "hydrogenated vegetable oil", "vegetable cream" and "shortening", it means that the food contains trans fatty acids. In addition, the main component of coffee companion "non-creamer" is also "hydrogenated vegetable oil", and the main source of frankincense in bubble tea is also "hydrogenated vegetable oil". Hydrogenated vegetable oil contains no cholesterol and is cheaper than animal cream, so margarine is used instead of animal cream. Call on everyone to stay away from trans fatty acids.
