Its impossible to not get blindsided by HFCS and the general sugar content of American foods if you compare the retail shelves like for like with Europe.
In Ireland and other European countries they literally have to 'cover up' the Breakfast Cereals in the 'American Speciality/Import' section due to their misleading nutritional information and/or child targeting.
For example, American formulation PopTarts have to legally cover up the claim on the front that they are "a good source of nutrition" and another sticker on the back with a factual nutritional breakdown, as is mandated by most EU members.
