Do you check your labels?
Food manufacturers must list the sodium content on the label, and many also indicate the actual salt content.
To see how much salt is in the product you’re buying:
Multiply the sodium content, usually given as per 100g serving, by 2.5.
Sodium content 0.8g/100g: 0.8g x 2.5 = 2g of salt per 100g
In the food label on the right, the sodium content is 25mg, or 0.025g, and so is well within the daily limit.
