Reference intakes explained

You'll see reference intakes referred to on food labels. They show you the maximum amount of calories and nutrients you should eat in a day.

Daily reference intakes for the average adult aged 19 to 64 are:

The reference intake for total sugars includes sugars from milk and fruit, as well as added sugar.  

See How much sugar is good for me? to learn more about added sugar and the sugar in milk and fruit. 

Reference intakes aren't meant to be targets. They just give you a rough idea of how much energy you should be eating each day and how much fat, sugar, salt and so on.

Unless the label says otherwise, reference intakes are based on an average-sized woman doing an average amount of physical activity.

This is to reduce the risk of people with lower energy requirements eating too much, and to make sure information on labels is clear and consistent.

How can I tell if a food is high in fat, saturated fat, sugars or salt?

There are guidelines to tell you if a food is high in fat, saturated fat ("saturates"), sugars or salt, or not:

Fat

High in fat: more than 17.5g of fat per 100g
Low in fat: 3g of fat or less per 100g

Saturated fat (saturates)

High in saturates: more than 5g of saturates per 100g
Low in saturates: 1.5g of saturates or less per 100g 

Sugars

High in sugars: more than 22.5g of total sugars per 100g
Low in sugars: 5g of total sugars or less per 100g

Salt

High in salt: more than 1.5g of salt per 100g
Low in salt: 0.3g of salt or less per 100g 

So, for example, if you're trying to cut down on sugar, you should avoid foods that have more than 22.5g of sugars per 100g.

If you want to eat fewer saturates, it's best to avoid foods that have more than 5g of saturates per 100g.

The red, amber and green colour coding on the front of food packs helps you see at a glance whether a food is high (red), medium (amber) or low (green) in fat, saturated fat, sugars or salt.

Where to find reference intakes on food packs

If you look closely at food packaging, you'll see that it usually tells you what percentage of your daily reference intakes each portion of that food contains.

For example, the label above, taken from a box of apple pies, shows that each pie will provide you with 19.2g of sugars, which is 21% of your daily reference intake for sugars.

The red colour shows you that the pies are high in sugar.

Each pie also contains 2.9g of saturated fat, which is 15% of your reference intake for saturated fat.

The amber colour tells you that the pies contain a medium amount of saturated fat.

Green means a food is low in a particular nutrient. These pies, for example, are low in salt.
