Flaxseed oil is rich in ω-3 unsaturated fatty acids, which have important physiological functions: 1. Prevent cardiovascular and cerebrovascular diseases. ω-3 unsaturated fatty acids (α-linolenic acid) in flaxseed oil can reduce triglycerides, reduce thrombosis, maintain vascular elasticity, prevent coronary artery spasm and thrombosis, and reduce the occurrence of cardiovascular and cerebrovascular diseases. 2. Brain-strengthening and intelligence-improving. The main component of human brain tissue is lipid, and omega-3 unsaturated fatty acids account for about 20% of the total, while about 40% of the lipid in human retina is omega-3 unsaturated fatty acids. α -linolenic acid is further converted into EPA and DHA after entering human body. It plays an important role in the intellectual development of infants, improving memory of teenagers, strengthening the brain of middle-aged and elderly people and preventing Alzheimer's disease.
