The Important In Terms of Health of Flax (Linum usitatissimum L.)

Abstract

The flax is one of the oldest known cultivated plants of the World that benefited from seeds and fibers. It is an important nutrient because of the rich α-linolenic acid (ALA, omega-3 fatty acid), lignans, short chain polyunsaturated fatty acids, soluble and insoluble fibers, phytoestrogenic lignans (secoisolariciresinol diglycoside-SDG), waxy and mucilage compounds, protein and antioxidant compounds. In addition, the seed contains components effective in reducing cardiovascular disorders, diabetes, digestive system, urinary tract disorders, osteoporosis, cancer, arthritis, autoimmune and neurological diseases. Seed protein content varies between 20-30%, of which approximately 80% consists of globulins and 20% glutelines. The amino acid level is so rich and gluten-free. The unconscious consumption of seed may cause toxicity due to trypsin, myo-inositol phosphate inhibitors, cadmium and cyanogenic glycosides in the seed. The seed should be consumed as milled flour after absolute heat treatment. Side effects may be seen in pregnant and young men due to hormonal effects of lignan. It may be oxidized shortly after grinding due to the fatty acids present in the seed. Flax fibers (Linen) have been used in house and fabric textiles, sailing and tent making since 7040 BC. The fibers are gold-yellow in color, the qualitative and moisture absorption capacity is very low, easily creasing. For this reason, the linen keeps the skin cool and does not sweat. Fiber is also an important source for healthy insulation materials, biocomposites, structural application materials for automotive, contributing both to the environment and to human health. In this paper, the effects of flax on human health and methods of traditional uses in Turkey were discussed with references.
