The food choice is US-centric as already pointed out, I want to add that doesn't impact only the macros, but also the prices and availability.
For example foods like Buckwheat and Peanut Butter are hard to find in Italy (at least in my region), and when you find them are very expensive (example Buckwheat is around 2£/KG in the UK and around 15€/KG in Italy).
Regarding the macros, the change of proteins, based on the nation is impressive.
Example:
Best cottage cheese I can find in Italy: 7% Carbs, 0% Fats, 93% Proteins https://www.myfitnesspal.com/it/food/calories/naturella-fioc...
Best cottage cheese I can find in UK: 11% Carbs, 26% Fats, 63% Proteins https://www.myfitnesspal.com/food/calories/light-cottage-che...
Best "cottage cheese" I can find in Lithuania: 11% Carbs, 0% Fatas, 89% Proteins

You could add in the receipt the macros of the ingredient we need to use, in this way at the super market I can scan various of them and search the closest one
