Introduction
Under normal circumstances, flaxseed oil can help lower blood lipid levels. However, it should be noted that flaxseed oil only serves as an adjunct and cannot replace lipid-lowering medications. Consumption should be controlled, with a recommended daily intake not exceeding 10-15 milliliters, as excessive intake may lead to excessive calorie consumption. Additionally, flaxseed oil is not heat-resistant and is best used in cold dishes or as a seasoning in low-temperature applications.

Generally, flaxseed oil can assist in lowering blood lipids. The detailed analysis is as follows:

Flaxseed oil is rich in alpha-linolenic acid (ALA). ALA is an Omega-3 unsaturated fatty acid that promotes cholesterol metabolism in the body, reduces the deposition of low-density lipoprotein on blood vessel walls, and simultaneously increases the level of high-density lipoprotein, thereby helping to regulate lipid balance. Additionally, the unsaturated fatty acids in flaxseed oil can improve blood viscosity and promote blood circulation, offering some preventive benefits against cardiovascular issues caused by abnormal blood lipids.

However, it should be noted that flaxseed oil only serves as an adjunct and cannot replace lipid-lowering medications. Consumption should be controlled; it is recommended not to exceed 10–15 milliliters daily, as excessive intake may lead to excessive caloric intake. Moreover, flaxseed oil has a low smoke point and is best used in cold dishes or as a seasoning at low temperatures, avoiding high-heat cooking that may damage its nutritional components. If blood lipid problems are severe, medical treatment under a doctor's guidance is necessary. A comprehensive approach that includes a healthy diet incorporating moderate consumption of flaxseed oil is needed for better blood lipid control.
