People with carotid atherosclerotic plaques are advised to consume low-salt, low-fat, vitamin C-rich and high-quality protein-containing foods, but the exact role can vary from person to person. Carotid atherosclerotic plaque is due to lipid deposition caused by the endothelium of the blood vessel thickening and thickening plaque, this lesion is closely related to the high blood lipid content. Therefore, some low cholesterol foods such as fish, various kinds of lean meat, foods rich in vitamin C, such as fresh fruits and vegetables, and foods rich in high quality protein such as beans and their products are more favorable for controlling the progress of the disease. However, it should be noted that the effects of different foods on the body may vary depending on the individual’s physical condition and the severity of the disease. Therefore, those who are diagnosed with the disease must make dietary adjustments under the guidance of a doctor according to the actual situation of the individual, and must not blindly dispose of the food on their own to avoid improper intervention and adverse consequences.
