经科学家调查证明,产棉区广大棉农长期食用粗制棉油可引起“低血钾软病”。主要症状是四肢对称性无力或驰张性瘫痪、麻木、酸软,走路时易跌跤,蹲下再站立就困难,有的不能抬头转颈。部分病人有恶心呕吐、烦渴、多饮、多尿,严重者可致呼吸麻痹死亡。此病以青壮年女性发病较多,也可引起男性和女性不育症。原因是粗制棉油中含有一种有毒的酚类物质,可引起肾小管病变,血钾由肾脏丢失。钾是调节人体生理功能必不可少的物质,血钾降低便使人出现上述一系列症状。为防止“低血钾软病”的发生,生产棉油必须全部精炼,其中所含的有毒有害物质 According to the investigation by scientists, cotton growers in the cotton producing area can cause “hypokalemia and soft tissue disease” for a long time. The main symptoms are limb weakness or Chi Zhang weakness or paralysis, numbness, sour, easy to fall when walking, squat and then stand on the difficult, and some can not look up the neck. Some patients have nausea and vomiting, polydipsia, polydipsia, polyuria, severe cases can cause respiratory paralysis death. The disease to young women more incidence, but also can cause male and female infertility. The reason is that crude cotton oil contains a toxic phenolic compounds that can cause tubular lesions, potassium is lost by the kidneys. Potassium is an essential substance that regulates the physiological functions of the body, and lowering of serum potassium causes the above-mentioned series of symptoms. In order to prevent the occurrence of “hypokalemia and soft tissue disease”, the production of cottonseed oil must be fully refined, and the toxic and harmful substances contained therein
