Reading ingredient lists is helpful in determining
sodium content. They list the ingredients in a food in
descending order.
Following is an ingredient list for a typical processed cheddar
cheese:
- Cheddar cheese, enzyme-modified cheddar cheese
(milk, cheese culture, salt, enzymes), water, lactic acid, enzymes, milkfat,
sodium citrate, kasal, salt, sodium phosphate, sorbic acid (preservative),
apocarotenal (color)
You can see that cheese is the main ingredient, but also note that
salt is present in two places and that it also contains sodium citrate and
sodium phosphate, which are two other types of sodium.
