🚨仅在德国，维生素D每年就能预防3万例癌症死亡。超过 900 项研究表明维生素 D 对大多数癌症类型具有抗癌活性，随机对照试验表明，维生素 D 可使癌症死亡率降低约 13%。已证实受益的癌症包括：• 胸部• 前列腺• 结直肠• 肺• 脑（胶质母细胞瘤）• 黑色素瘤• 卵巢• 膀胱• 头部和颈部• 多发性骨髓瘤这些作用是通过维生素 D 受体 (VDR) 信号传导、免疫调节和肿瘤微环境控制介导的。如果50岁及以上的成年人每天定期补充适量维生素D：➡️每年挽救约 30,000 条生命（仅德国一国）➡️每年增加约322,000个寿命年➡️每年净节省医疗保健费用约2.8亿美元➡️费用：每人每年约11-55美元一些最有效的癌症预防工具既不新颖也不盈利。🚨Vitamin D Could Prevent 30,000 Cancer Deaths Per Year in Germany AloneOver 900 studies show anti-cancer activity of vitamin D across most cancer types, and randomized controlled trials demonstrate a ~13% reduction in cancer mortality.Cancers with demonstrated benefit include:• Breast• Prostate• Colorectal• Lung• Brain (glioblastoma)• Melanoma• Ovarian• Bladder• Head & neck• Multiple myelomaEffects are mediated through vitamin D receptor (VDR) signaling, immune modulation, and tumor microenvironment control.If adults aged 50+ received routine vitamin D supplementation at modest daily doses:➡️ ~30,000 lives saved per year (Germany alone)➡️ ~322,000 life-years gained annually➡️ ~$280 million in net healthcare savings per year➡️ Cost: ~$11–$55 per person annuallySome of the most powerful cancer-prevention tools are neither novel nor profitable.
