The average Australian eats far too much salt – almost double the recommended daily maximum of 5 grams, equivalent to a teaspoon.
Useful context: “salt” (used above) =/= “sodium” (the thing you normally see on the nutrition label in Australia).
5 grams of salt is equivalent to 2000 mg of sodium, since sodium chloride is 40% sodium and 60% chlorine by weight.
Apparently less relevant for keto: https://www.livestrong.com/article/554837-sodium-potassium-and-the-ketogenic-diet/
(I don’t know much about nutrition on keto so can’t fact check that source, but it seems pretty reasonable)
