Linseed has long serve as a dual-purpose crop, yielding mutually high-quality fiber and oil-rich seeds. Flax fiber is sturdy, flexible, and highly absorbent, making it valuable in textiles, ropes, specialty papers, and biodegradable composites. The seeds are loaded in alpha-linolenic acid (ALA), an essential omega-3 fatty acid, along with dietary fiber, minerals, lignans, vitamins, and protein. ALA has been linked to many health benefits, including reduced risks of cardiovascular disease, hypertension, stroke, and inflammatory disorders. It serves as a plant-based precursor to EPA and DHA, significant for immune and cellular functions. With increasing interest in functional foods, flaxseed is being more and more recognized for its therapeutic potential. It is now included into a variety of food products and dietary interventions aimed at improving health. Although it has nutritional advantages, the awareness of flaxseed’s health benefits is limited. Further research and public education are needed to increase its acceptance and utilization. From an industrial standpoint, flaxseed oil contains over 50% linolenic acid, appropriate for industrial applications but less advantageous for cooking. Low linolenic acid varieties such as LINOLA and SOLIN have been developed to address this, with similar breeding efforts underway in India. Future breeding should focus on reducing anti-nutritional factors, enhancing omega-3 bioavailability, and improving tolerance to drought and disease using both conventional and molecular tools. Thus, linseed offers huge potential as a nutritionally rich, multipurpose crop. Advancing its agronomic traits and promoting its health benefits through research and innovation will improve its role in sustainable agriculture, nutrition, and industry.
