Steve, read the labels. Does the UK not have nutritional and calorie
break outs on the label (i.e. calories from carbs, fats, etc.).
Also find out what they think a serving is, vs. what YOU think a
serving is. The package will often say, serves 4 or 6 or whatever, or
says a serving is so many grams, and the serving size is impossibly
tiny by most people's standards.
