Britain and the United States have taken significant steps to curb the influence of junk food and ultra-processed foods (UPFs), marking what experts describe as a decisive shift in global nutrition and public health policy.
In recent weeks, both countries have introduced or reinforced measures that move beyond individual responsibility and place greater scrutiny on commercial practices that drive unhealthy eating habits, particularly among children.
From January, the UK has implemented a statutory ban on advertising unhealthy foods on television before 9 pm and imposed a complete prohibition on paid online advertising of such products. The British government estimates the measures will eliminate around 7.2 billion calories from children’s diets annually and help prevent tens of thousands of future obesity cases.
The policy is grounded in evidence showing that exposure to advertising for ultra-processed foods displaces healthier dietary choices and increases consumption. Officials have stressed that reducing marketing exposure is a critical lever in tackling rising rates of obesity and diet-related diseases.
In the US, the recently released Dietary Guidelines for Americans 2025–2030 have, for the first time, explicitly called for a substantial reduction in consumption of highly processed foods and products with added sugars. The guidelines link such diets to obesity, pre-diabetes and other chronic health conditions and recognise food processing itself as a health risk factor, not merely nutrient composition.
Backed by federal law and reinforced through school food standards, the updated guidelines carry significant policy weight. The language marks a departure from earlier approaches that focused narrowly on individual nutrients, which allowed companies to reformulate products without addressing broader health concerns.
Further signalling momentum in the US, a bipartisan bill — the Childhood Diabetes Reduction Act — is under consideration in Congress. If enacted, it would mandate health warning labels on ultra-processed foods and explicitly link their consumption to increased risks of childhood diabetes. While the legislation is yet to be passed, it reflects growing political consensus around the need for stronger consumer protection.
Public health experts say these developments weaken long-standing arguments that restrictions on food advertising harm business interests or infringe on free speech. With two major economies introducing statutory ad bans, stricter dietary guidance and considering warning labels, similar measures are increasingly viewed as reasonable public health interventions rather than regulatory overreach.
The policy shift has wider implications for emerging markets such as India, where consumption of ultra-processed foods is rising rapidly alongside increasing rates of overweight and obesity. Data from the National Family Health Survey (NFHS-5) show significant increases in obesity among children, adolescents and adults, even as undernutrition persists.
Experts note that children in India are exposed daily to junk food marketing across television, digital platforms, gaming apps and influencer content, while regulatory oversight remains fragmented and largely voluntary.
With global regulatory momentum building, policymakers are increasingly framing advertising restrictions and clearer labelling as essential consumer protection tools. The developments in the UK and US underline a broader trend: ultra-processed foods are no longer being treated merely as lifestyle choices, but as a public health challenge requiring decisive policy action.
