Can flaxseeds still be consumed after their expiration date?
Disease description:
My uncle has hypertension and elevated triglycerides. A friend gave him a bottle of flaxseed to help regulate his blood lipid levels, but he recently discovered that it has expired. May I ask: Is it still safe to consume flaxseed after its expiration date?

Flaxseed is a nutrient-rich food, but it is generally not recommended for consumption after its expiration date. It is rich in alpha-linolenic acid (ALA) and lignans—compounds that help boost energy levels, support brain health and mental calmness, and enhance the body’s ability to cope with stress. For young and middle-aged adults, flaxseed serves as an excellent functional food, offering significant preventive benefits against cardiovascular and cerebrovascular diseases such as hyperlipidemia, hypertension, and certain cancers. Notably, the fatty acids in flaxseed serve as a vital energy source for the brain, and its metabolic derivative—DHA—further contributes to visual improvement and protection. However, once flaxseed expires, both its nutritional value and safety are significantly compromised; therefore, consumption is not advised.
