Have you ever thought about words and what they mean? Many words have several different meanings depending on the context in which they are used. For example take the word “salt”. ‘Salt’ is commonly used to refer to one specific kind of salt, called sodium chloride (NaCl) or table salt. However, because salt has an important place in our history there are also a number of phrases using the word salt with different meanings than ‘sodium chloride’. For example you might have heard “take it with a grain of salt”, “to be worth one’s salt”, or to “salt away for future use”.
Sometimes the words “salt” and “sodium” are used interchangeably. For example, when dietitians and doctors talk about salt they are probably referring to sodium.
That is because it is the sodium part of sodium chloride (salt) that raises blood pressure. Since salt is the primary source of sodium in Canadians’ diets it may seem reasonable that the words ‘salt’ and ‘sodium’ often get treated as the same thing. Salt and sodium may seem similar, but they are different. If salt was a recipe, then sodium would be one of its two ingredients. While salt is our primary source of
sodium there are a number of other common food ingredients that also contain sodium. Here are some examples.
Just a few thoughts to salt away for future contemplation.
