Nutrient Reference Values
Recommended Daily Allowances (RDA) on food packaging have recently been replaced with Nutrient Reference Values (NRV). These are values for the daily amounts of certain vitamins and minerals we need to stay healthy. On food packaging, the amount of a specific vitamin and/or mineral in a portion of the food is often compared with the NRV and then shown as a percentage of it. For example, the NRV for vitamin B12 is 2.5mcg. A 170g portion of raw cod contains 2.5mcg vitamin B12, so that’s 100 percent of the NRV.
