For each of almost 30 countries, it has a photograph of an average family with all the food that would comprise a normal week's consumption, accompanied with a description and cost. (Not all families are from separate countries. Some larger countries have two families from different regions).
Later, the authors published an expanded version as a book, which I believe covers 80 families.
I think there is at least one more subset of photos other than the set TIME published that has been published in some major online magazine, because I am sure I saw one of a German family whose weekly consumption included an amazing amount of beer, and that doesn't match the German family in the TIME article.

These are adult breakfasts, not kid breakfasts.
