It is wise to Store all user data in session or unique id of database?

I am making a simple social networking site in Express Node Js Using mongo db. There are users info in database that is to be displayed in many pages.

If I store a user Id of my db collections as a session variable, each time I should write db query to find user of that ID and display their info. Would it better if I store all the info of that user as a session variable.

Or, there is another better approach

You hold session variable for a certain amount of time (if the user is not active anymore) or until you destroy session (logout). In other words why you need to retrieve information over and over when you can hold it in session... use session :)
