@alfredoolivas are you referencing higher sodium consumption in the late medieval/early modern period of 1600-1700s? unusually high numbers like daily 40 grams, and daily 100 grams in Sweden, are because of people using consumption data of salt, but that's innacurate, because it takes a whole nation's sodium import, when the vast majority was used for preservation, and not consumed. It's probably impossible to consume much more than 12 grams of salt a day for an extended period, and I even question the 18 grams numbers thrown around about 1800s Western nations, because China has the same economic number of total consumption per person, but then at the individual eating level it's something like 10 grams on avg.
What makes china cool, is they didn't really undergo an industrial-liberal health and food revolution like America did, so they're probably eating more consistently according to what the avg agrarian society ate for thousands of years (meat in every form, offal, grain, salt to taste, sugar to taste, seasonal fruits, boiled veg, etc).
