今年4月25日至5月1日是第23个全国《职业病防治法》宣传周。为适应经济社会发展新形势新要 求，新版《职业病分类和目录》（下称《目录》）新增"职业性肌肉骨骼疾病""职业性精神和行为障 碍"两个类别，将职业性腕管综合征、创伤后应激障碍纳入《目录》，直击制造业工人、医疗卫生人 员、消防救援人员等群体的职业健康"痛点"。 也应看到，职业病防治工作仍然任重道远。一方面，随着新技术、新业态的不断涌现，职业病的种 类和表现形式也在不断变化，这就要求我们不断更新和完善职业病目录，确保防治工作的及时性和有效 性。另一方面，职业病防治是个系统工程，需要政府、企业和劳动者的共同参与和努力。 政府部门应加大监管力度，确保用人单位严格遵守职业病防治相关法律法规，为劳动者提供安全、 健康的工作环境。同时，还应加强职业病防治的宣传教育，提高劳动者的自我防护意识和能力。用人单 位则应切实承担起职业病防治的主体责任，积极改善工作条件，为劳动者配备符合人体工程学的设备， 减少重复性劳损。此外，还应建立健全职业病防治制度，加强员工健康管理，及时发现并处理职业病危 害因素。劳动者自身也应提高健康意识，合理安排工作时间和强度，避免长时间连续使用电脑 ...

叶酸蛋 DHA蛋 富硒蛋 虾青素蛋成鸡蛋界新宠 内卷鸡蛋 是大补丸还是智商税 现如今人们不费吹灰之力就实现了"鸡蛋自由"，市面上的鸡蛋品种也日趋多样化，叶酸鸡蛋、DHA鸡 蛋、富硒鸡蛋、虾青素鸡蛋等琳琅满目。这些鸡蛋界的高端产品，究竟是商家的噱头还是浓缩营养库？ 营养定制鸡蛋是这样来的 鸡蛋是富集营养素的理想载体。鸡蛋由母鸡产出，母鸡自身的健康程度及营养素沉积对鸡蛋的质量和营 养成分的含量起着决定性作用。从这个角度讲，通过营养调控手段"定制"能够调节机体生理功能的鸡 蛋，就可以满足不同人群对营养素的特定需求。 也正是基于此，在母鸡的饲养过程中，通过使用特定饲料原料和优化配制生产，可以使鸡蛋中的某些特 定营养成分较之普通鸡蛋显著提高或降低。利用鸡蛋富集某些营养物质，如矿物质、ω-3多不饱和脂肪 酸、维生素等，为人类提供功能性营养物质，进而改善机体健康，已经成为品牌鸡蛋开发的新热点。 叶酸生物营养强化鸡蛋 叶酸，也被称为维生素B9，因最初是从菠菜叶子中分离提取出来而得名。在日常生活中提到叶酸，首 先想到的是孕妇和胎儿，叶酸是人体必需的微量营养素之一，摄入不足易导致孕妇巨幼红细胞贫血、先 兆子痫和胎盘早剥的发生率增 ...
