Nova -grupper för livsmedelsbearbetning

En klassificering i 4 grupper för att belysa graden av bearbetning av livsmedel

In the report "The UN Decade of Nutrition, the NOVA food classification and the trouble with ultra-processing" (pdf, pdf), Carlos Augusto Monteiro, Geoffrey Cannon, Jean-Claude Moubarac, Renata Bertazzi Levy, Maria Laura C. Louzada and Patrícia Constante Jaime advocate for the adoption of a system of grades from 1 to 4 to allow to simply compare the degree of processing of products.

New research associating researchers from Inserm, Inra and the Paris 13 University (Centre de recherche épidémiologie et statistique Sorbonne Paris Cité, équipe EREN) suggest a correlation between the cosumption of ultra-transformed foods and an increased risk of developing a cancer.

Some countries use the NOVA groups for their dietary guidelines or goals, for instance:

Brazil's dietary guidelines recommend to limit consumption of processed food and avoid ultra-processed food.
France's public health nutritional policy goals for 2018-2022 aims to reduce consumption of group 4 ultra-processed foods by 20%.

NOVA -klassificeringen tilldelar en grupp livsmedelsprodukter baserat på hur mycket bearbetning de har genomgått:

Grupp 1 - Obearbetade eller minimalt bearbetade livsmedel
Grupp 2 - Bearbetade kulinariska ingredienser
Grupp 3 - Bearbetade livsmedel
Grupp 4 - Ultrabehandlade mat- och dryckesprodukter

Grupp 1. Obearbetade eller minimalt bearbetade livsmedel

Unprocessed (or natural) foods are edible parts of plants (seeds, fruits, leaves, stems, roots) or of animals (muscle, offal, eggs, milk), and also fungi, algae and water, after separation from nature.

Minimally processed foods are natural foods altered by processes that include removal of inedible or unwanted parts, and drying, crushing, grinding, fractioning, filtering, roasting, boiling, non-alcoholic fermentation, pasteurization, refrigeration, chilling, freezing, placing in containers and vacuum-packaging. These processes are designed to preserve natural foods, to make them suitable for storage, or to make them safe or edible or more pleasant to consume. Many unprocessed or minimally processed foods are prepared and cooked at home or in restaurant kitchens in combination with processed culinary ingredients as dishes or meals.

Grupp 2. Bearbetade kulinariska ingredienser

Processed culinary ingredients, such as oils, butter, sugar and salt, are substances derived from Group 1 foods or from nature by processes that include pressing, refining, grinding, milling and drying. The purpose of such processes is to make durable products that are suitable for use in home and restaurant kitchens to prepare, season and cook Group 1 foods and to make with them varied and enjoyable hand-made dishes and meals, such as stews, soups and broths, salads, breads, preserves, drinks and desserts. They are not meant to be consumed by themselves, and are normally used in combination with Group 1 foods to make freshly prepared drinks, dishes and meals.

Grupp 3. Halvfabrikat

Processed foods, such as bottled vegetables, canned fish, fruits in syrup, cheeses and freshly made breads, are made essentially by adding salt, oil, sugar or other substances from Group 2 to Group 1 foods.

Processes include various preservation or cooking methods, and, in the case of breads and cheese, non-alcoholic fermentation. Most processed foods have two or three ingredients, and are recognizable as modified versions of Group 1 foods. They are edible by themselves or, more usually, in combination with other foods. The purpose of processing here is to increase the durability of Group 1 foods, or to modify or enhance their sensory qualities.

Grupp 4. Ultra-processed foods

Ultra-processed foods, such as soft drinks, sweet or savoury packaged snacks, reconstituted meat products and pre-prepared frozen dishes, are not modified foods but formulations made mostly or entirely from substances derived from foods and additives, with little if any intact Group 1 food.

Ingredients of these formulations usually include those also used in processed foods, such as sugars, oils, fats or salt. But ultra-processed products also include other sources of energy and nutrients not normally used in culinary preparations. Some of these are directly extracted from foods, such as casein, lactose, whey and gluten.

Many are derived from further processing of food constituents, such as hydrogenated or interesterified oils, hydrolysed proteins, soya protein isolate, maltodextrin, invert sugar and high-fructose corn syrup.

Additives in ultra-processed foods include some also used in processed foods, such as preservatives, antioxidants and stabilizers. Classes of additives found only in ultra-processed products include those used to imitate or enhance the sensory qualities of foods or to disguise unpalatable aspects of the final product. These additives include dyes and other colours, colour stabilizers; flavours, flavour enhancers, non-sugar sweeteners; and processing aids such as carbonating, firming, bulking and anti-bulking, de-foaming, anti-caking and glazing agents, emulsifiers, sequestrants and humectants.

A multitude of sequences of processes is used to combine the usually many ingredients and to create the final product (hence 'ultra-processed'). The processes include several with no domestic equivalents, such as hydrogenation and hydrolysation, extrusion and moulding, and pre-processing for frying.

The overall purpose of ultra-processing is to create branded, convenient (durable, ready to consume), attractive (hyper-palatable) and highly profitable (low-cost ingredients) food products designed to displace all other food groups. Ultra-processed food products are usually packaged attractively and marketed intensively.

Novapoäng på Open Food Facts

The formula for calculating the Nova score were published in the NOVA. The star shines bright article published in World Nutrition Volume 7, Number 1 - 3, January - March 2016

Please note that this is still experimental work as multilingual taxonomisation of ingredients is still an ongoing work on Open Food Facts.

Formel för att bestämma Novagruppen

Vi börjar med att tilldela grupp 1

Vi försöker först identifiera grupp 2 bearbetade kulinariska ingredienser

Ingredienser och kategorier associerade med grupp 3 kommer inte att tillämpas på livsmedel identifierade som grupp 2

Ingredienser och kategorier som endast finns i grupp 4

Du kan hjälpa oss att bestämma Nova -gruppen för fler produkter genom att fylla i ingredienserna och produktkategorierna.
