I don’t know if you list ingredients in order of priority, but you have Sugar BEFORE water as the most common ingredient? I’m also not sure if we have a requirement to explicitly declare what the sugar is (i.e your label explicitly differentiates between HCFS and Sucrose)
I got the US listing from Burger King and every soft drink apart from the Fruit Juice, milk and Coffee uses it as a sweetner. The Milkshakes use it in both the syrup and the base mix.
And having tried a twinkie once, I get the impression that while portion sizes might be more or less the same, you use twice as much sugar as we do ;).
