What characterizes NOVA category 4 foods?

NOVA category 4 foods are characterized as ultra-processed foods that typically contain artificial ingredients, additives, and substances not commonly found in a home kitchen. These foods often undergo significant industrial processing and may include components such as flavor enhancers, preservatives, emulsifiers, and other types of food additives that extend shelf life or enhance taste, texture, and color. Examples include sugary drinks, packaged snacks, instant noodles, and ready-to-eat meals that are far removed from their original food sources, highlighting their reliance on industrial processes and chemical formulations.

In contrast, the other categories defined by NOVA focus on less processed options, which emphasize natural or minimally altered foods. This distinction is crucial in understanding the nutritional implications of various food types, as ultra-processed foods are often linked to negative health outcomes when consumed in high quantities.
