I think there is a lot more variety than one photo suggests. The link someone posted from time magazine, where the weekly food of a family is shown seems to be much more representative (look at the nice fresh vegetables and fruits in non-western countries).

For the record: my german kids breakfast: oatmeal without sugar, dried fruits, milk from the local farmers cow, fresh fruits from our own garden, tea. bread with home made jam (from our gardens fruits ;o). Toast with Nutella only on sundays, but my mothers jam was so much better...
