Consumption of food oils in small amounts does not cause elevated blood lipids, but if you eat too much or eat fried foods regularly, you are likely to experience elevated blood lipids. The source and discharge of blood lipids are generally in dynamic balance. Consumption of food oils in small amounts usually does not cause elevation of blood lipids. However, if there is excessive intake or impaired elimination, elevated blood lipids may easily occur. If a large amount of cooking oil is used for a long time, or if fried food is eaten frequently, the liver will be overloaded to metabolize fat for a long period of time, which will lead to a decrease in the liver’s ability to metabolize fat, and elevated blood lipids will appear. Elevated blood lipids can be improved by increasing sports and exercise to burn calories and avoid obesity. In addition, it is recommended to develop good dietary habits and control the intake of high-fat and high-calorie foods, especially greasy and fried foods. If the blood fat is elevated, it is recommended to consult a doctor in time, choose the appropriate lipid-lowering drugs under the guidance of a professional doctor, and take the drugs as prescribed by the doctor to prevent the occurrence of coronary heart disease and other diseases.
