1. Defining Ultra Processed Foods: What Are They?
Ultra-processed foods (UPFs) are industrial formulations made from a series of manufacturing processes. These foods often bear little resemblance to their original ingredients and are designed for convenience, long shelf life, and high palatability. They represent a significant shift from traditional, whole foods and have become increasingly prevalent in global diets.
1.1. The NOVA Classification System
The NOVA classification system categorizes foods into four groups based on the extent and purpose of industrial processing:
- Group 1: Unprocessed or Minimally Processed Foods: These are whole foods in their natural state or foods that have undergone minimal processing, such as drying, grinding, or pasteurization. Examples include fruits, vegetables, grains, legumes, and meat.
- Group 2: Processed Culinary Ingredients: These are substances extracted from Group 1 foods or from nature, used to season and cook foods. Examples include oils, fats, sugar, and salt.
- Group 3: Processed Foods: These are relatively simple products made by adding Group 2 ingredients to Group 1 foods. The purpose is to preserve or enhance the qualities of the original foods. Examples include canned vegetables, salted nuts, and cured meats.
- Group 4: Ultra-Processed Foods: These are industrial formulations made from refined ingredients and additives, with little or no whole foods. They are designed to be palatable, convenient, and profitable. Examples include soft drinks, packaged snacks, and processed meats.
1.2. Characteristics of Ultra-Processed Foods
Ultra-processed foods are characterized by:
- High levels of processing: They undergo multiple industrial processes, such as extrusion, molding, and pre-frying.
- Use of industrial ingredients: They contain ingredients that are rarely or never used in home cooking, such as high-fructose corn syrup, hydrogenated oils, and protein isolates.
- Addition of cosmetic additives: They include additives that enhance their sensory properties, such as flavors, colors, emulsifiers, and sweeteners.
- Aggressive marketing: They are heavily marketed and branded, often targeting children and using health claims.
- Long shelf life: They are designed to be shelf-stable and convenient to consume.
