Unhealthy food and beverage companies powerfully undermine the eating habits of young people by deploying ubiquitous ads that encourage poor dietary choices and increase the risk of serious disease and premature death, according to a sweeping new study published in Obesity Reviews. The first-of-its-kind summary highlights a clear cumulative pattern: The more high-fat, high-sugar, and salty food ads young people see, the more of those products they consume"and the higher the risk that they may develop obesity, type 2 diabetes, and other diet-related diseases. Companies also disproportionately target adolescents, lower-income communities, and Black and Latino youth with the marketing of health-harming food and beverages. The review summarizes 25 years of scientific evidence and findings from 108 empirical studies and 19 systematic reviews of unhealthy food marketing to adolescents (13-17) and young adults (18-25). One study showed that children who watched just five minutes of food ads ate about 130 more calories that day. Only 19% of studies examined health impacts, but most of those found links between unhealthy food marketing and higher BMI, weight gain, or increased obesity risk"especially from ultra-processed foods and sugary drinks. One U.S. study ... found that children who could recall more food ads chose more food items and consumed more calories after exposure.
