Dietary statistics

Edible amount per person per year (kg/liter)
Shows the total edible amount of sold food and beverages per person per year in kg/liter.
Total edible amount of sold food items during a calendar year / Total population

Edible amount per person per day (grams)
Shows the total amount of sold food and beverages per person per day in grams.
(Total amount of sold food items during a calendar year / Total population) / 365 days in a year

Edible portion
It is the edible part of sold food items used to calculate the total amount of consumed food and beverages and the content of nutrients. This means the amount of food and drink after packaging, skin, peel, bones, or other parts that are usually not eaten have been removed. Additionally, salt purchased in packages over 1 kg is removed from the population. No adjustments are made for food waste.

Nutritional content
The statistics present the content of energy (MJ and kcal) and nutrients (grams or kg) in sold food and beverages and include the following:

• Energy (MJ)
• Energy (kcal)
• Protein (g)
• Total fat (g)
  • Saturated fat (g)
• Carbohydrates (g)
  • Sugars (g)
• Dietary fiber (g)
• Salt (g)
• Alcohol (g)
• Protein, energy percentage (E%)
• Fat, energy percentage (E%)
  • Saturated fatty acids, energy percentage (E%)
• Carbohydrates, energy percentage (E%)
  • Sugars, energy percentage (E%)
• Dietary fiber, energy percentage (E%)
• Alcohol, energy percentage (E%)

Energy
Energy can be expressed in kJ (MJ = 1,000 kJ) or kcal. The energy content of food items is calculated based on the content of protein, fat, carbohydrates, dietary fiber, and alcohol. The reported amounts for Energy are summed up.

Units of measurement and conversion factors for energy
The internationally accepted unit for energy is joule (J), but many still use calories (cal). The energy content of food items is usually given in kilojoules (kJ) or kilocalories (kcal).

1 kJ = 0.239 kcal or 1 MJ = 239 kcal
1 kcal = 4.184 kJ or 1 kcal = 0.004184 MJ

Fat
Fat is reported in grams or kg. There are three main types of fat in food: saturated fatty acids, unsaturated fatty acids, and trans fatty acids.

Saturated fat
Saturated fat is reported in grams or kg.

Carbohydrates
Carbohydrates are reported in grams or kg. The values for carbohydrates are calculated as the sum of starch and sugars, meaning available carbohydrates.

Sugars
Sugars are reported in grams or kg. Sugars (mono- and disaccharides) are the sum of various types of naturally occurring and added sugars. More specifically, this includes naturally occurring glucose (grape sugar), fructose (fruit sugar), lactose (milk sugar), maltose (malt sugar), and sucrose (table sugar) or other sugars added during processing. In nutrition labels, this sum is referred to as sugars. Naturally occurring sugars in food items are not considered added sugar.

Protein
Protein is reported in grams or kg.

Salt
Salt is reported in grams or kg. Salt, sodium chloride (NaCl), is a combination of the elements sodium (Na) and chlorine (Cl).

Dietary fiber
Dietary fiber is reported in grams or kg. Dietary fiber is not included in carbohydrates.

Alcohol
Alcohol is reported in grams or kg and applies only to alcohol from beer and cider purchased in grocery stores. Therefore, it does not include wine and spirits. On labels of alcoholic beverages, the alcohol content is usually given as a volume percentage. In the presentation of alcohol content, however, it is converted to weight percentage, meaning grams per 100 g of drink. For beer, wine, and other alcoholic beverages with approximately the same density as water, i.e., 1, the weight percentage is calculated as 0.8 times the volume percentage.

Energy percentage (E%)
The portion of the total energy content in the diet that comes from carbohydrates, fat, protein, and alcohol is often given in the term energy percentage or E%.

The energy content of energy-yielding nutrients is:
1 g fat = 37 kJ or 9 kcal
1 g protein = 17 kJ or 4 kcal
1 g carbohydrate = 17 kJ or 4 kcal
1 g alcohol = 29 kJ or 7 kcal

National Food Grouping
National health authorities need to present dietary statistics using a classification system that is better suited to Norwegian conditions than COICOP. This is necessary, among other reasons, to enable comparisons with national statistics in the area. The national classification system is mainly based on the grouping in COICOP combined with various threshold values for nutrients, such as sugar, salt, fat, and dietary fiber.

The classification contains 15 main groups:

A. Cereals
B. Meat, meat products
C. Fish, seafood, products of fish and seafood
D. Milk, dairy products, eggs
E. Oil, butter, margarine
F. Fruits and berries, products of fruits and berries
G. Nuts, seeds
H. Potatoes, potato products
I. Vegetables, vegetable products
J. Sugar, sweets, jams, etc.
K. Ready-to-eat dishes
L. Salt, spices, sauces
M. Other food items
N. Non-alcoholic beverages
O. Beer, cider, alcoholic beverages
Z. Unclassified food and beverages

The 15 main groups contain subgroups and subgroups of subgroups. The complete code list for the classification of food groups can be found here: https://www.ssb.no/klass/klassifikasjoner/716

The statistics distributed by food groups are provided as follows:

• Average edible quantity of sold food and beverages per person per year (kg)
• Average edible quantity of sold food and beverages per person per day (grams)

The statistics distributed by Energy and Nutrients are provided as follows:

• Average amount of energy (MJ and kcal) and nutrients (grams) per person per day based on sold food and beverages
