cuz eggs are in breakfast sandwiches, are ingredients in pastries, act as binders in things like meatloaf or fried chicken, etc. etc.

That sounded high to me as well(probably because I rarely eat eggs), but then I remembered my parents who each eat two per day which isn't that uncommon I guess.

Maybe if you include all the eggs in processed food like cookies or cakes and in restaurants or other catering operations you reach that number? And eggs consumed at home could still be around 12 per person?
