Per 100g doesn't make it easy to compare a bag of chips to a can of soda.

Unless you carry around a food scale to measure out all your snacks, I fail to understand why 100g^-1 is useful.

I would however be interested in a pie chart that displays the calories from different macros. Then tic tac would be 100% sugar and you could compare to soda, also 100% sugar, or chips, which are maybe 65% fat and 5% protein and 30% carbs.

I don't mean to be snarky, but there's always a weight listed on stuff, I think that removes the requirement for carrying a food scale?

Sure, but now we're back to the current US system, where you have to multiply or divide by the amount in the container (either servings per container, or grams per container) to make sense of the measurement.

Standardizing to 100g doesn't actually make it easier to compare foods, because I don't know how 100g of popcorn compares to 100g of chocolate or 100g of soup. It just doesn't mean anything to me.

Just list the amount in the container.

From my experience, it does make it easier if you need to compare similar foods.

For example, I want to buy a yogurt with highest amount of protein. Serving sizes may vary between 150 and to 500gr. With standardized labels it is very easy task.

In my country we have calories listed for both 100g/container and nutrients are always listed for 100g and sometimes for full contaiber. I almost always use 100g part.

In the US, serving sizes are generally standardized per type of food, so two quart containers of yogurt will always have the same serving size in the nutrition facts.

There is quite a bit of water in soda. While there is a lot of sugar, it is about 10% which is a bit less than 100. Specifying per 100g (or some other size) makes it quite easy to compare two different products. Of course you also have to take into consideration how much of the product you will consume

[bagacrap]

The percentage being expressed is (calories from X)/(total calories). For soda and sugar, that comes to 1.
