Healthy vs. Healthful
How to use "healthy" and "healthful" correctlyThis is an entry on my list of Common Errors in English Usage. Visit the main page for direct links to additional entries.
Healthy is traditionally used to describe one’s state of health:
healthy children
healthy teeth
Healthful is used to describe something that promotes good health, and even today it should not be used to describe one’s state of health:
healthful childrenhealthful teeth
healthful diet
healthy diet
The second example above, “healthy diet,” is acceptable in contemporary usage but considered incorrect by some traditionalists, who feel that healthy should not be used as a synonym for healthful.
