Malnourished children, bustling cafes, and one fifth of mankind

I saw this headline a little while ago:

Israel's strike on bustling Gaza cafe killed a Hamas operative - but dozens more people were killed

I thought that strange. Don't we always read about famine in Gaza? Only a few seconds more poking around at the BBC turns up this example:

One in five children in Gaza City is malnourished, UN aid agency says

Well, which is it, malnourished, or bustling?

But I was pretty sure I'd seen that "1 in 5" statistic before, regarding America's children. A quick web search turns up an obvious example:

1 in 5 Children Over 13 million kids don't have enough food to grow up strong.
Hunger in America [archived]

In fact, it seems that fraction--1 in 5--seems to apply to many maladies across many human populations. Maybe that says something about our nature.
