Froot Loops is a sweetened, fruit-flavored breakfast cereal made by WK Kellogg Co for the United States, Canadian, and Caribbean markets and Kellanova for the rest of the world. The brand was solely owned by the original Kellogg Company before it spun off its North American cereal division as WK Kellogg Co in late 2023. The fruit-flavored cereal pieces are ring-shaped, with a variety of bright colors. Although appearing in different colors, every color has the same flavor.
An ultra-processed food (UPF) is a grouping of processed food characterized by relatively involved methods of production. There is no simple definition of UPF, but they are generally understood to be an industrial creation derived from natural food or synthesized from other organic compounds. The resulting products are designed to be highly profitable, convenient, and hyperpalatable, often through food additives such as preservatives, colourings, and flavourings. UPFs have often undergone processes such as moulding/extruding, hydrogenation, or frying.
Ultra-processed foods first became ubiquitous in the 1980s, though the term "ultra-processed food" gained prominence from a 2009 paper by Brazilian researchers as part of the Nova classification system. In the Nova system, UPFs include most bread and other mass-produced baked goods, frozen pizza, instant noodles, flavored yogurt, fruit and milk drinks, diet products, baby food, and most of what is considered junk food. The Nova definition considers ingredients, processing, and how products are marketed; nutritional content is not evaluated. As of 2024, research into the effects of UPFs is rapidly evolving.
