WHO: 5 percent of calories should be from sugar
Even though I've been reading that headline on my portal page for 3 days now and know what it's really supposed to be saying, I still can't read it the way they intended. The first sentence of the actual article:
The World Health Organization says your daily sugar intake should be just 5 percent of your total calories — half of what the agency previously recommended, according to new draft guidelines published Wednesday.
Even that sentence doesn't really say they'd be happy with 4 percent, or would previously have been happy with less than 10%. But at least the "just" cancels an otherwise implicit "at least". There's a lot of literature about when numbers are interpreted as "exactly" and when as "at least", and about where exactly those two kinds of interpretations come from. But unless they occur with suitable modifiers or in particular constructions, they are never freely interpreted as "at most". So unless we're supposed to believe that WHO wants everyone to get exactly 5% from sugar, that headline is just wrong, I believe.
No big deal. I just had to say it after three days of suffering in silence.
