The Nova classification (Portuguese: nova classificação, 'new classification') is a framework for grouping edible substances based on the extent and purpose of food processing applied to them. Researchers at the University of São Paulo , Brazil , proposed the system in 2009.
A feeding tube is a medical device used to provide nutrition to people who cannot obtain nutrition by mouth, are unable to swallow safely, or need nutritional supplementation. The state of being fed by a feeding tube is called gavage, enteral feeding or tube feeding. Placement may be temporary for the treatment of acute conditions or lifelong ...
On the second point, he and his team developed the Nova classification, which is now used worldwide to measure the increasing consumption of ultra-processed foods. [ 1 ] [ 2 ] He is scientific editor-in-chief of the Brazilian public health journal Revista de Saúde Pública (as of November 2022) [ 3 ] and was co-editor of the journals Public ...
Monteiro's team subsequently presented ultra-processed foods as a group in the Nova food classification system. [6] The system focuses on food processing rather than foods types or nutrients. Nova categorizes foods into four groups: [3] unprocessed or minimally processed foods, processed ingredients, processed foods, and ultra-processed foods.

Ram feeding and suction feeding are on opposite sides of the feeding spectrum, where extreme ram feeding is when a predator swims over an immobile prey item with open jaws to engulf the prey. Extreme suction feeding is demonstrated by sit-and-wait predators that rely on rapid depression of the jaws to capture prey (e.g., frogfish, Antennariidae).
Bread, cheese, salted food and other prepared foods have been sold for thousands of years, but these typically require a much lower level of industrial processing, as reflected in systems such as the Nova classification. Other types of food were developed with improvements in food technology. Types of convenience foods can vary by country and ...
Organotrophs use organic compounds as electron/hydrogen donors. Lithotrophs use inorganic compounds as electron/hydrogen donors.. The electrons or hydrogen atoms from reducing equivalents (electron donors) are needed by both phototrophs and chemotrophs in reduction-oxidation reactions that transfer energy in the anabolic processes of ATP synthesis (in heterotrophs) or biosynthesis (in autotrophs).
