Nutrition facts

Some nations like the UK use red, amber, and green colour codes to express how healthy a processed food is in terms of fat, saturates, sugars and salt. 

For example, a processed meal might have 7.7g of saturated fat and be labelled red. It may also show a percentage like 39%. The amount is calculated using the "Reference intake", which is the maximum recommended intake amount for an adult woman who does an average amount of physical activity.
