Ultra-processed food

Ultra-processed food refers to industrially processed food products that are typically high in sugar, fat, and salt, but low in vitamins and fiber. These foods are often packaged and marketed for their convenience and long shelf life. They include items such as soft drinks, packaged snacks, instant noodles, and ready-to-eat meals.

Definition

The term "ultra-processed food" was coined by a research group at the University of São Paulo in Brazil. It is defined by the NOVA classification system, a food classification system that categorizes foods based on the extent and purpose of their processing, rather than their nutrient content. Ultra-processed foods are classified as "Group 4" in the NOVA system, which includes foods that are made predominantly or entirely from industrial substances and contain little or no whole foods.

Health effects

Numerous studies have linked the consumption of ultra-processed foods to a variety of health problems. These include obesity, heart disease, type 2 diabetes, and certain types of cancer. The high levels of sugar, fat, and salt in these foods, combined with their low levels of essential nutrients, are believed to contribute to these health risks. In addition, the processing methods used to produce these foods can result in the formation of potentially harmful substances, such as acrylamide and trans fats.

Regulation and public health initiatives

In response to the health risks associated with ultra-processed foods, several countries have implemented regulations and public health initiatives aimed at reducing their consumption. These include taxes on sugary drinks, restrictions on food advertising, and front-of-pack nutrition labeling systems. The World Health Organization and the Pan American Health Organization have also issued guidelines recommending the reduction of ultra-processed food consumption.
