I didn't add any salt to the stuff I cooked today, and the food with the most sodium was the soy milk I had this morning. Roughly estimating sodium intake from serving sizes, put me at about .5 g. Doubling for not bothering to lookup the sodium content of brussel sprouts, carrots, onions, still leaves me somewhat shy of the 1.6 g/day the british nutrition foundation recommended.
Wait, did that miso take me over? no it didn't.
What did those mediaeval peasants do to get enough salt?
