In the editorial I am writing, I repeatedly say "healthy foods". I searched healthy up in a thesaurus so my paper would not sound so repetitive. The results were ones such as
fit, active, lively, robust, strong, etc.

I am not looking for "healthy" that means athletic or fit, I am looking for healthy that means good for you.
The sentence in which "healthy foods" is used is
Eating healthy foods and drinking water five to seven times in a day is essential to an active brain and body.
