> seems prone to the same serving size tricks used in US I've only noticed it on what we call "squash", or fruit juice concentrate. When I was a kid, the labels would say 1 part concentrate to 6 parts water, and we'd do it about 1 to 4. Now, we've gone through double concentrate and a lot are "4x" now, but e.g. the bottle in front of me says "typical values per 100ml (diluted 1 part with 19 parts water)" and a serving size of 250ml (which actually provides more precision than the per 100ml value). I think these standard serving sizes are defined somewhere, as I think it's always 250ml for every kind of drink that comes from a large container, and either the exact quantity or an integer division of it for things that come in smaller containers, e.g a 330ml can. The way it handles quantities is interesting. When is seems to mean trace, it uses "<0.1g" as distinct from a small amount where it uses "<0.5g". Sugars are listed as "0.5g" in the 250ml serving and "<0.5g" per 100ml. Fibre and protein are "<0.5g" everywhere, and fat is the weird one as it says "<0.5g per 250 ml, of which saturates <0.1g, mono-unsaturates <0.1g, polyunsaturates <0.1g". Finally, you can be pretty sure of the actual composition due to the calories, listed as 15kJ or 4 kcal per 250ml (use the kJ puts this at 3.5-37kcal per 250ml). Knowing that sugar is 3.87kcal per 1g, protein is 4.0kcal per 1g and fat is 898kcal per 1g (most people approximate per gram to 4 for carbs+protein and 9 for fat). So for the 0.5g of sugar, that's approx 2kcal, so there's either about 0.4g of protein or about 0.2g of fat or somewhere in-between. Just from what's in the juice, I expect the "missing calories" are mostly protein. Obviously, none of that tells you anything about lactose (except that it's fruit juice and there's no reason why it would contain any). Ingredients rather than final foods typically specify nutrition "per 100g as sold" and invent a serving side either by telling you how to prepare it (e.g. OXO gravy cubes say to dissolve 1 cube in 190ml of water for 2 servings) or invent some arbitrary serving size like 5g for a condiment. This seems in line with what you've seen, but definitely squash that is intended to be diluted doesn't do that (at least in the UK, and for the squash I buy).
