Is there anyone who knows all the regeneration food for all the food groups??

Check from here

Just browse through all foods until you find it, it's usually the 2:00 hours timer one.

Do you mean "Restore" to use during gluttony to keep gluttony sessions useful, or "Regen" to use while working/hunting to keep humors full?

You can also look in this tables: http://salemwiki.info/index.php/Food
It helps a much.
The first Table is for Heal Values.
This Food with more than one uses are your friend!

If you look for Restore Food while a Gluttony... the third table is your Friend!
A little side hint: Look for Cabbage Crush Salad.
