How to choose edible oils? Is it healthy to eat only one oil for a long time?

　　Suggestions for reasonable use of oil

　　1. Buy small bottles (if you buy a large barrel of oil please try to finish it within 3 months) and pay attention to keep the oil bottle lid hygienic. It is best to keep the oil in a cool and dry place in a sealed place, away from the stove and light. In addition, when replacing the oil bottle, be careful not to mix the old oil with the fresh oil. It is recommended to use glass oil bottles with a smarter design where the amount of oil used can also be controlled.

　　2. Because the composition of fatty acids in different vegetable oils is different, each has its own nutritional characteristics. Therefore, it is recommended to alternate different types of oil, 1-2 months, such as eating sunflower oil this month, while change to tea oil next month, etc.

　　3. It is recommended that animal oil can be used as a condiment and not as a common oil for cooking, but it is okay to eat some occasionally.

　　4. People with chronic diseases such as hyperlipidemia, diabetes and hypertension are recommended to reduce the amount and frequency of animal fat consumption or replace it with vegetable oil.

　　5. Limit the intake of trans fatty acids. Reduce the consumption of foods labelled with "partially hydrogenated vegetable oil", "shortening", "creamer", "phyllo" and "margarine". "Margarine".

　　6. Since some of the fats and oils are left in the soup when cooking, people who need to reduce or limit their daily oil intake are advised to drink less soup and eat less rice in vegetable soup.
