Can flaxseed oil prevent cardiovascular diseases?

Generally speaking, flaxseed oil can help prevent cardiovascular diseases, but its effectiveness is limited. Detailed analysis is as follows:

Flaxseed oil is rich in Omega-3 fatty acids, which can lower the level of triglycerides in the blood. Elevated triglycerides are one of the risk factors for cardiovascular diseases, and reducing their levels can decrease the burden on blood vessels. The unsaturated fatty acids in flaxseed oil can improve vascular endothelial function, enhance vascular elasticity, prevent vascular hardening, and help maintain normal vascular dilation and contraction. Additionally, the antioxidant substances in flaxseed oil can inhibit oxidative stress reactions within blood vessels, reduce plaque formation, and provide some protective effect on vascular health. However, the occurrence of cardiovascular diseases is related to multiple complex factors such as genetics, hypertension, hyperlipidemia, and smoking. Relying solely on flaxseed oil is insufficient to comprehensively prevent disease development, thus its effectiveness is limited.

Flaxseed oil cannot replace medications for the prevention and treatment of cardiovascular diseases. It should be consumed in moderation, as excessive intake may lead to excessive calorie consumption, which is detrimental to health. It should be combined with a low-salt, low-fat diet and regular exercise to better maintain cardiovascular health. When storing flaxseed oil, it should be sealed and kept away from light to prevent the degradation of nutrients and reduce its effectiveness.
