Where can I find published or written information on what the diet of indians consisted of?

Go to your local public library. Ask the librarians to show you books on Indian life and culture (are you referring to Native Americans or those from the country of India?). Either way, ask the librarians to help you with this.

There are PLENTY of books on Native American life and culture. There may be variations depending upon what part of the N.American continent the tribes are from. (more fish from the coasts, more game from the interior).
