Perhaps you should try some spelling variations:
"cost of a health does" » "cost of a health do", "cost of a health deep", "cost of a health der"
"cost of a health diet" » "cost of a healthy diets", "cost of a health dietary", "cost of a healthful diet"
"cost of a healthy diet" » "cost of _ healthy diet"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("cost of a health does") OR ("cost of a health diet"))) OR ("cost of a healthy diet")).
• Removing quotes may allow a broader search: (((( cost of a health does ) or ( cost of a health diet ))) or ( cost of a healthy diet )).
• Adding a wildcard symbol may retrieve word variants: (((("cost of a health does") or ("cost of a health diet"))) or ("cost of a healthy diet"))*.
