What? Surely that’s not how nutrition labels are made. If I look at the label for almonds and I look at the label for tofu and they both list 100g of X has Y protein in it - surely they’re comparable. So what is your point? Are you suggesting I need to dehydrate tofu to determine it’s real nutrition? I don’t know if that’s practical or meaningful in anyway. I guess you’re suggesting that if we cook out the water certain foods like tofu get even more macro nutritionally dense?
In the US nutrition labels are per serving not per 100g. A serving of tofu might weigh 123 grams while a serving of almonds is 20 grams. Because the tofu is full of water. You can’t easily compare nutrition content for foods based on their weight.
US labels also contain weight. And again, unless you are baking all the water out and curious about that nutritional value, you’re picking up a package that has nearly identical labeling and testing standards and are therefore comparable and using that to make nutritional choices. In this case almonds are more calorically dense than tofu and have less protein per calorie. Water included or not.
