If your goal is to consume 1,500 mg or less per day of sodium that’s more than 1/3 of your sodium intake for a day.
One teaspoon of table salt can contain as much as 2360 msg of sodium.
Different types of salts may have more or less sodium per 1/4 teaspoon. The same amount of salt can have more or less sodium depending on the size of the salt grains.
1/4 teaspoon of larger grain salts, like pink Himalayan sea salt and kosher salt, will contain less sodium because fewer of their larger grains will fit into your measuring spoon.
If you are using salt in small quantities, measure the amount you can safely add to your recipe before you start cooking so you can be confident in the amount you’re using.
