Fabrizio Zago ha scritto:Il bicarbonato è solubilissimo in acqua e quindi NON può, semplicemente, abradere meccanicamente i denti. Questa sì che è una leggenda metropolitana.
Il bicarbonato sì, ovviamente

. Ma l'argilla verde un po' meno

visto che contiene ossidi e idrossidi di alluminio e ferro. Non so se stiamo parlando della stessa ricetta.
A quale domanda ti riferisci? quella sugli studi che pongono seri dubbi sull'utilità del fluoro e mettono in guardia sui rischi per la salute? Ho postato un articolo pieno zeppo di appendice bibliografica e, in più, la posizione ufficiale dell'Unicef in materia, che a sua volta cita come fonti degli studi in materia.
Copio & incollo nuovamente la bibliografia dell'articolo del Dott. Perugini:
