The word: salubrious
It means 'health giving' or 'health promoting'. For example, something can be salubrious...such as exercise.
What a wonderful tool for marketing acai juice or kashi cereal...just tell people that it's salubrious! This seems much better than 'it will promote health and well-being'- just sum it all up with salubrious.
God I hope the marketers don't read blogger...
