Hello Marblehead, Manitou, thank you for the kind welcome.
Manitou, I'd never heard of Diaitajuice until you mentioned it so I can't comment on it.
You are correct in your understanding that "Diaita" is the root word for "Diet", however Diaita is much broader in scope. The ancient greek usage of δίαιτα (Diaita) refers to "way of living", which includes certainly includes diet but also includes the antique definition of hygiene.
From Wikipedia:
"Diaita" is therefore in many ways analogous to Daoist health and hygiene practices
