Concetto di Indice glicemico e sua importanza nell'alimentazione umana

Tra gli elementi sui cui si basa il Programma Bioimis, rientra anche il concetto di Indice Glicemico, quindi il controllo dell’aumento dello zucchero (glucosio) dopo i pasti.

L’importanza della velocità di assorbimento del glucosio a livello intestinale è rappresentata dal concetto di indice glicemico, ormai studiato da più di trent’anni ma di cui non si è ancora compresa la grande importanza per la salute e il benessere sugli esseri umani.

La sottovalutazione del concetto dell’indice glicemico è dovuta al fatto che ancora si usa il concetto termodinamico della Caloria (o del Joule) nelle scienze dell’alimentazione.

Il Programma Bioimis, invece, considera di fondamentale importanza il controllo dell’aumento dello zucchero (glucosio) dopo i pasti.
