Cholesterol is an important component that makes up the cells and provides energy to the body, and high cholesterol means that the amount of cholesterol in the body’s blood exceeds the amount required by the body. There are many causes of high cholesterol, and diet is one of them, but there are no clear clinical top ten dietary contraindications for high cholesterol. If the patient has high cholesterol, common foods that need to be contraindicated are: 1, foods with high cholesterol content: when cholesterol is high, try not to eat foods with high cholesterol, such as egg yolk, animal offal, fatty meat, cream, butter, shellfish, etc.; 2, foods high in saturated fatty acids: when patients are found to have high cholesterol, try not to eat foods rich in saturated fatty acids, such as animal fats, so as not to cause further elevation of blood lipids ; 3, high carbohydrates: avoid eating large amounts of carbohydrates, such as rice, steamed bread, sorghum, noodles, bread, cookies, etc., so as not to further increase the level of cholesterol. When patients have high cholesterol in their body, they can eat more foods rich in dietary fiber, vitamins, phospholipids and iodine to increase the conversion of cholesterol into bile acids in the body and speed up the conversion and storage of cholesterol. At the same time, attention should be paid to reduce smoking and drinking to avoid damage to the liver and increase in cholesterol.
