The normal range for triglycerides in clinical practice is between 0.45 and 1.7 mmol/L. If it exceeds this range, it usually indicates high triglycerides. For patients with high triglycerides, they must pay attention in their daily life not to eat foods with high cholesterol, high calories and high carbohydrates, such as bacon, pickled and fried foods; fatty meat, animal offal foods, egg yolk, butter, fish roe and other foods should be prohibited; they should also limit the intake of cookies, cakes and other desserts; puffed foods or processed products, nuts and other foods should be reduced. In addition to the above dietary contraindications, patients are advised to choose a low-salt, low-fat diet, eat more fresh fruits and vegetables, and combine appropriate exercise for weight loss, as well as moderate consumption of tea to increase the flexibility of blood vessels, which can help reduce triglyceride levels. In addition, patients should also pay attention to regular monitoring of blood lipids and take triglyceride-lowering drugs if necessary to prevent the occurrence of fatty liver or liver cirrhosis or pancreatitis.
