Note: 'Prescribed nutrition labelling' is required when a claim is made and the conditions attached to that claim require 'prescribed nutrition labelling' (see Claims). In other cases, the provision of nutrition labelling is voluntary but, when given, it must be in the format of 'Prescribed nutrition labelling' given below.
Certain terms used in nutrition labelling have been defined and only substances falling within the definition can be included in calculating nutrition values. These terms include: fibre, fat, saturates, mono-unsaturates, polyunsaturates, protein, carbohydrate and sugars. For these terms see: Nutrition Definitions

from the actual average values of the ingredients used in the preparation of
the food, and/or iii) a calculation from generally established and accepted
