Daily Intake Guide: Healthy eating, made easy. Front-of-pack labelling for food and drink in Australia.

Reality Check: The Australian Food and Grocery Council recognises that this possibility needs to be addressed and has done so through:

an agreement regarding serving size principles, and
specific agreements within certain categories.

The principles (see below) recognise that items intended as single serves should be so designated and that multiple serve products should be a reasonable multiple of the single serve.

For example, the beverage industry has agreed that product up to and including 600ml should be designated single serves and that above that size, a single serve shall be 250ml.

AFGC SERVING SIZE PRINCIPLES

It is the manufacturer’s responsibility to determine the serving size for a food or beverage product, but they must reflect the agreed industry serving size principles developed by the AFGC as follows:

When determining serving sizes consideration should be given to authoritative nutrition guidance (for example, Australian Dietary Guidelines, Australian Guide to Healthy Eating).
The serving size should be realistic and should consider eating habits across the day, as part of a healthy diet.
Single serve items should be cognisant of the target market (for example adults or children).
If a product is packed in such a way that is can be reasonably expected to be consumed by the target consumer in one eating occasion, then the pack size should be the serving size.
For multi serve products with recognisable portion units (for example, slices of bread) serving sizes should be communicated with references to these units (for example, serving size 74g – 2 slices). For all other multi serve products manufacturers should consider the use of additional terminology to communicate the serving size to consumers (for example, serving size 74g – ½ cup).
Serving sizes must not be used inappropriately to manipulate the energy or nutrient content per serving.
Serving sizes must not promote over-consumption.
