the guardian has messed up their headline a bit here. The paper they're citing attributes a 9.7% decrease in children's total sugar consumption to the sugar tax.
The "sugar consumption halved!" is more accurately: "free sugar from soft drinks only" dropped from 22g per day (pre-tax) to 12g per day (post-tax).
Considering "Children aged 7 to 10 should have no more than 24g of free sugars a day" is the recommended amount - a reduction from 22g to 12g from changes to soft drinks alone is still a big win
