Just an example of how you'd output it in a view, I'm sure you can
adapt it from there to extract whatever values you want:
<% @parsed_response[0]['searchresults']['category'].each do |cat| %>
<h1><%=h cat['name']%></h1>
<p>
<h3>Foods</h3>
<% cat['foods']['food'].each do |food| %>
<p><%=h food['id']%> - <%=h food['display']%></p>
<% end %>
</p>
<% end %>
