In 1990, the US Congress passed the Nutrition Labeling and
Education Act, which requires that total sugar, but not caffeine
content, be disclosed on labels of beverages and dietary supplements.
(Some manufacturers disclose caffeine voluntarily.) The FDA has the
authority to require scientifically based warning labels on SSBs, similar
to the Surgeon General’s warning on tobacco products.
In the EU, sugar disclosure is voluntary, unless a nutrient claim is
made on packaging or in advertising, in which case it becomes
mandatory. The EU does not require caffeine content be disclosed on
cola-type beverages, but if the beverage contains caffeine in excess of
150 mg/l, the message, ‘High caffeine content’, must appear on the
label
