Oh yeah - I've had to start watching my carbohydrate intake for health reasons and it's amazing just how much of that stuff is in processed food: for example "American Style Onion Rings (frozen)" from Lidl is over 40% carbohydrates - so basically the 450g pack of it has 180g of sugars and the kind of stuff your digestive system will turn into sugars.
One would think it would be only starchy foods (like bread, pasta, rice and such) and cakes and sweets that have lots of it, but no, most processed food is loaded with carbohydrates, often already directly as sugars, probably because the cheapest ingredient to bulk it up is flour.
Mind you, lots of natural or lightly processed foods have quite a bit of it - for example natural yoghurt with nothing added has maybe 6% of carbohydrates (tough yoghurt with fruit is way worse, since the adding of fruit is generally mixing it with fruit jam which has a lot of sugar) and most fruits have quite a bit of sugar (for example, common varieties of apple have about 14% of sugar - so your run of the mill apple comes with 1 spoonful of sugar included - and some varieties have a lot more) which is why there's this funny paradox that natural fruit juice has a lot more sugar in it than the same amount of Coca-Cola (since when you make the fruit juice you throw away the fiber and most of the protein leaving a much higher percentage of sugar than originally).
Generally, the kind of stuff that has almost no carbohydrates are veggies, like lettuce or broccoli.
