While the packages are the same size, the package you saw is the US version where the counting of calories varies slightly.
In the US, the calorie calculation is slightly different. While fat is still 9 calories per gram and protein is still 4 calories per gram, fibre is counted as a carbohydrate with 4 calories per gram. 4 + 9 + (4×6) = 37 calories! Then, they are rounded to the nearest 5 calories, and hence in the US, nuPasta has 35 calories per package!
