IL SODIO & LA COMPOSIZIONE CORPOREA

Sodio,indicazioni,rischi e benefici Troppo sale fa male. Ormai e' risaputo,troppo sale alza la pressione e porta a problemi cardiovascolari.

Troppe persone si focalizzano sul contenuto di Sodio nelle acque,quando le stesse hanno un BASSISSIMO quantitativo di Sodio (pochi mg,da 10 a 200 per litro).Dovrebbero invece controllare dove e' nascosto il sale,in quasi tutta la totalita' dei ''cibi'' industriali (piatti pronti,''cibi'' precotti,junk food,ecc),nel pane raffinato,nei formaggi,quantita' di Sodio che puo' arrivare anche a 1.2/1.5gr per pezzo.

Gli Sportivi/Atleti hanno bisogno del Sodio,troppo fa male..Ma anche troppo poco crea Ritenzione Idrica.

Fonti autorevoli consigliano circa 2.5/3gr/die di Sodio (circa 5-6gr di sale),con poco o senza Sodio si ALZA l'Aldosterone e la maggior parte dell'acqua finisce nel comparto extracellulare (creando cosi Ritenzione Idrica,con aspetto appannato,muscoli ''sgonfi'')

Si puo' usare il sale Novosal (ricco di Potassio,al 30%) o il sale marino grezzo integrale.1 gr di sale da cucina apporta 0.4gr di Sodio.
