![]() ![]() Other researchers, such as Julie Hess, a nutritionist at the U.S. But through the lens of NOVA, both are ultraprocessed. ![]() Take fortified breads or protein-rich cookies, for example: Compared with their unfortified equivalents, they would be considered relatively nutritious. When NOVA first came about in 2009, it offered a new way of looking at food beyond its nutritional value. The categories are unprocessed or minimally processed foods (which include vegetables and eggs) processed culinary ingredients (those that are usually added to food and rarely eaten alone, such as oils, butter and sugar), processed foods (those that are made from a combination of the first two groups, such as homemade bread) and ultraprocessed foods (those made with industrially modified raw ingredients and additives). Researchers commonly use a four-part scale known as NOVA to categorize foods based on the extent of industrial processing they involve. “You can’t tell simply by the ingredients.” For example, he says, “it’ll be flour, but you really don’t know that wheat flour has been decomposed in such complex ways and then put back together.” “A whole lot of things that you could never imagine can be done ,” says Barry Popkin, a professor of nutrition at the University of North Carolina at Chapel Hill. What are ultraprocessed foods?Ĭhicken nuggets, chips and hotdogs are considered ultraprocessed, but so are things such as fruit yogurts, mass-produced bread and even some canned foods.Īs a rule of thumb, these are any foods that cannot be made in an ordinary kitchen-in other words, they contain an ingredient that is not typically found in homes or one that has undergone an industrial process that a home cook would not be able to replicate. It’s worse for kids and teenagers, whose diet is almost 70 percent ultraprocessed.īut a growing number of studies have linked higher consumption of ultraprocessed foods to a long list of health effects, and scientists are only just beginning to understand why. adults consume are from ultraprocessed foods. These foods also have a variety of additives that help bind the ingredients together, increase their shelf life or make them more palatable.Īccording to some estimates, nearly 60 percent of the daily calories U.S. This often includes steps such as hydrogenation, which produces semisolid oils, and hydrolysis, which enhances flavors. Ultraprocessed foods undergo an industrial process to move from farm to table. Both frozen chopped spinach and canned sausages are processed, but the latter has undergone much more processing than the former. In other words, if there is any change from the way the food began to the way it ends up on a shelf, it counts as processed.īut then there are ultraprocessed foods. You might think you know a processed meal when you see one, but here’s some food for thought: nearly everything you can eat at the supermarket has undergone some kind of processing-such as washing, blanching, canning, drying or pasteurizing. ![]()
