If you check the salt/sodium levels in the packets and cans in your food cupboards you may be surprised at how high they are. On labels, more than 0.5g of sodium (1.25g salt) per 100g is high, less than 0.2g sodium (0.5g salt) is low. To convert sodium content to salt content, multiply the sodium by 2.5
