Comments on many tables database design issue

Question

I have tables:

Articles{...}

SELECT TOP 1000 [Comments_Id]
      ,[Comments_Text]
      ,[Comments_IsApproved]
      ,[Comments_IsVisible]
      ,[Comments_DateStamp]
      ,[Type_Id]
      ,[Entity_Id] -- From Entity Table, listing Articles, Recipes etc. 
      ,[EntityItem_Id] -- One of the PK from table of Articles, Recipes etc.
      ,[User_Id]
  FROM [tbl_Comments]
