L'inganno del fluoro by Manish Upadhyay Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Sebbene un tempo il fluoro fosse considerato un nutriente essenziale, il Consiglio Nazionale delle Ricerche degli Stati Uniti ha eliminato questa designazione a causa della mancanza di studi che ne dimostrino l'essenzialità per la crescita umana, pur continuando a considerare il fluoro un "elemento benefico" per il suo impatto positivo sulla salute orale. Gli Stati Uniti specificano che il livello ottimale di fluoro varia da 0,7 a 1,2 mg/L (milligrammi per litro, equivalenti a parti per milione), a seconda della temperatura massima media giornaliera dell'aria; il livello ottimale è più basso nei climi più caldi, dove si beve più acqua, ed è più alto nei climi più freddi. Elevate concentrazioni di fluoruro (F-) nell'acqua potabile sono dannose per la salute umana.
