The increasing consumption of cheap fast food and lack of exercise have resulted in half of Brazilians being overweight, with 16% classified as obese. Scientists in Brazil studied the category of foods driving this trend, leading to the creation of a definition for ultra-processed foods in 2009. This definition includes foods like biscuits, breads, confectionery, ice cream, and soft drinks. Over the past decade, there have been numerous scientific papers directly studying ultra-processed foods, with additional research supporting the link between a poor diet and the consumption of ultra-processed foods. These food items are easily found in supermarkets and can be identified as products wrapped in plastic containing at least one ingredient not typically found in a home kitchen.
