Flaxseed oil, also known as linseed oil, is derived from the seeds of the plant Linium usitatissimum and is rich in Alpha Linolenic Acid (ALA), which is the biological precursor to Omega-3 fatty acids as well as containing Omega-6, Linoleic Acid (LA). It is important to maintain an appropriate balance of Omega-3 and Omega-6 in the diet as these two substances work together to promote health. Flaxseed oil and flaxseed contain substances that promote good health. Flaxseed oil is rich in Alpha Linolenic Acid (ALA), an essential fatty acid that is beneficial for heart disease, inflammatory bowel disease, arthritis and a variety of other health conditions. Flaxseed, in addition to ALA, contains a group of chemicals called Lignans that may play a role in the prevention of cancer.
