- Food Allergens – ingredients that are often allergens must be identified on the label.
- Nutrient Content – the quantity of the major nutrients; fats, carbohydrate, protein, salt, fibre and calories are listed per 100gm (and per serving size).
- Ingredients List – the ingredients are listed in order of quantity by weight.
- Dietary claims – when the producer makes claims about the food, eg ‘Low Fat’, ‘Free From’, he must provide information to support this claim.
1. Food Allergens
Alcohol as an ingredient must also be identified.
Some products claim that allergens are not in their product and are labelled as ‘Free From’. This term ‘Free From’ is specific for that particular ingredient only, not all food allergens. For example, a ‘Lactose Free’ product contains no lactose (milk sugar) but it may contain milk protein, and a ‘Gluten Free’ product may contain soya.
2. Nutrient Content
Typical values | 100 gm contains | Each slice (typically 44 gm) | % RI* | RI for an average adult |
Energy | 985 kj 235 kcal |
435 kj 105 kcal |
5% | 8400 kj 2000 kcal |
Fat | 1.5 gm | 0.7 gm | 1% | 70 gm |
as saturated | 0.3 gm | 0.1 gm | 1% | 20 gm |
Carbohydrate | 45.5 gm | 20.0 gm | ||
as sugars | 3.8 gm | 1.7 gm | 2% | 90 gm |
Fibre | 2.8 gm | 1.2 gm | ||
Protein | 7.7 gm | 3.4 gm | ||
Salt | 1.0 gm | 0.4 gm | 7% | 6 gm |
RI* – This information refers to the recommended intake of an average adult.
What is high and low in a nutrient? Below is a guide to help you understand the nutrient content labels*.
Total Fat:
High: more than 17.5 gm of fat per 100 gm
Low: 3 gm of fat or less per 100 gm
Saturated Fat:
High: more than 5 gm of saturated fat per 100 gm
Low: 1.5 gm of saturated fat or less per 100 gm
More information on types of fat (eg saturated, cholesterol and trans fat content) is useful and is available in the ingredient list
Sugars/Carbohydrate:
High: more than 22.5 gm of total sugars per 100 gm
Low: 5 gm of total sugars or less per 100 gm
(more details of carbohydrates and types of sugar is available on the ingredient list)
Salt:
High: more than 1.5 gm of salt per 100 gm (or 0.6 gm sodium)
Low: 0.3 gm of salt or less per 100 gm (or 0.1 gm sodium)

3. Ingredient List (including Food Additives)
The ingredient list is the contents listed in order of weight, the heaviest ingredient being first. This information can be used to assess the suitability of a food when read in conjunction with allergen and nutrient information.
Food additives are included in the ingredients list.
Do not be misled into thinking all additives are bad. Some have been used for hundreds of years and help maintain food quality. A good practice when trying to minimise additive intake is “if in doubt, go without”.
Fresh foods do not list additives (not possible really). However, additives may be used in food production and storage, even organic. Unfortunately, getting detailed information can be difficult unless you are shopping at a farmer’s market.
The additives permitted in food vary from country to country. For a guide on the uses of additives (emulsifiers, glazing agents etc):
http://en.wikipedia.org/wiki/List_of_food_additives
For a guidelines on National regulatory authorities:
http://en.wikipedia.org/wiki/Food_safety
Within the European Union (and Switzerland, Arab Gulf States, Australia and New Zealand) the International Numbering System prefix “E” (Europe) identifies the food additives used:
E100-E199 (colours)
E200-E299 (preservatives)
E300-E399 (antioxidants, acidity regulators)
E400-E499 (thickeners, stabilizers, emulsifiers)
E500-E599 (acidity regulators, anti-caking agents)
E600-E699 (flavour enhancers)
E700-E799 (antibiotics)
E900-E999 (glazing agents and sweetners)
E1000-E1599 (additional chemicals)

4. Dietary Claims
“Light” or “Lite”
These foods must be a minimum of 30% lower in calories or fat than the standard product. Compare food labels to see if the difference is significant. Often the difference is only a gram or two, so not worth the loss in flavour.
“Low fat”
These foods contain no more than 3gm fat per 100 gm or 1.5 gm fat per 100 ml (1.8 gm /100ml for semi-skimmed milk).
“No Added Sugar”
No sugar or sweetener is added to these products, although they may have a high sugar content from natural sugar (fruit or milk).
“Use By”
Use By is added to foods with a short shelf-life where there is a potential health risk if used after the indicated date.
“Best Before”
Best Before dates are about food quality. If the food has been stored as instructed, it should not be harmful after the Best Before date although it may lose flavour and texture. Eggs may be used after best Before Date if they are cooked thoroughly.
