title: add default content to custom taxonomy in wordpress
body: <p>I am trying to add the default data set to a custom taxonomy called 'foods'. The default data sets are; </p>
  
  <ul>
  <li>vegetarian</li>
  <li>salad</li>
  <li>carrot</li>
  <li>nonvegetarian</li>
  <li>chicken</li>
  <li>mutton</li>
  </ul>
  
  <p>I have already created the taxonomy called foods, but I am unable to add the default data to it. Please help. I really don't understand how to use wp_insert_term() in the WordPress codex.  </p>
