Perhaps you should try some spelling variations:
"cost of a health dies" » "cost of a health die", "cost of a health does", "cost of a health bodies"
"cost of _ health diet" » "cost of _ healthy diets", "cost of _ health dietary", "cost of _ 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 dies") OR ((("cost of a healthy diet") OR ("cost of _ health diet")))).
• Removing quotes may allow a broader search: (( cost of a health dies ) or ((( cost of a healthy diet ) or ( cost of _ health diet )))).
• Adding a wildcard symbol may retrieve word variants: (("cost of a health dies") or ((("cost of a healthy diet") or ("cost of _ health diet"))))*.
