Starting January 2026, the United Kingdom enforces a sweeping prohibition on television and online advertising for foods high in fat, sugar, and salt—part of a national effort to reduce health risks and promote better nutrition among children.
In Great Britain, a ban on junk food ads came into force on January 5. The aim of this legislation is to protect children from exposure to products high in sugar, fat, or salt, helping to counter rising rates of childhood obesity.
Under the new rules, such products may only be advertised on television after 9 p.m. Online, however, the restrictions go significantly further: Digital advertising for unhealthy foods is now prohibited entirely, regardless of time or platform. The affected categories include sweets, sugary drinks, potato chips, fast food, and highly processed convenience foods.
The British government expects this measure to reduce overall calorie consumption among children, thereby preventing thousands of future cases of obesity and lowering public healthcare costs. The policy follows a nutritional model that evaluates foods by their sugar, salt, and saturated fat content.
Criticism of the law has come from the advertising and food industries, which warn of economic consequences. Health organizations, however, welcome the initiative as a decisive step forward, emphasizing that children are highly susceptible to marketing and that eating habits established early in life often persist into adulthood.
