Why Ultra-Processed Foods Need Stronger Regulation

Ultra-processed foods, commonly known as UPFs, have become a major part of modern diets. From packaged snacks and sugary cereals to ready meals, soft drinks and processed meat products, these foods are convenient, affordable and widely available. Their popularity is understandable, particularly for people managing busy lives. However, growing evidence about the relationship between high consumption of ultra-processed foods and poor health raises an important public policy question: should governments do more to regulate them?

The answer should be yes.

Stronger regulation does not mean banning every packaged food or telling people what they can and cannot eat. It means creating a food environment in which healthier choices are easier to identify, easier to access and less aggressively marketed. It also means ensuring that commercial interests do not prevent governments from introducing reasonable measures designed to protect public health.

What makes ultra-processed foods different?

Not all processed food is unhealthy. Freezing vegetables, pasteurising milk, fermenting foods and using basic processing techniques can improve safety, convenience and shelf life. The concern surrounding UPFs is more specific.

Ultra-processed foods are generally industrial formulations containing multiple ingredients and additives, often designed to make products highly convenient, appealing and long-lasting. They can contain combinations of refined carbohydrates, added sugars, fats, salt, flavourings, colourings, emulsifiers and other additives.

Some UPFs can also be relatively high in calories while providing limited nutritional value. Because they are inexpensive, convenient and heavily marketed, they can become a substantial part of a person's diet without that person necessarily realising how much of their food comes from highly processed products.

This is where regulation becomes relevant.

The health evidence deserves attention

Research into UPFs has expanded rapidly in recent years. Studies have reported associations between higher consumption of ultra-processed foods and a range of health problems, including obesity, cardiovascular disease, type 2 diabetes and some cancers.

Importantly, the science is more complicated than simply saying that every UPF directly causes disease. Ultra-processed foods are a broad category, and observational studies cannot always establish a straightforward cause and effect relationship. Diets are also influenced by income, lifestyle, physical activity, education and other factors.

That uncertainty should not, however, be used as an argument for doing nothing.

When a category of foods becomes increasingly dominant in people's diets and is repeatedly associated with negative health outcomes, governments have a legitimate reason to examine the wider food environment. Public policy does not need to wait until every scientific question has been resolved before taking proportionate preventive action.

The problem is bigger than individual choice

One argument against stronger regulation is that people should simply make better choices. Personal responsibility is important, but it is not the whole story.

Consumers make decisions within an environment shaped by prices, advertising, product placement, availability and convenience. A sugary cereal promoted at a discount, displayed prominently in a supermarket and advertised repeatedly to families does not compete with fresh food on completely equal terms.

Marketing can also influence children's preferences from an early age. When unhealthy products are promoted aggressively, particularly through channels that reach young audiences, expecting individuals to overcome the full weight of commercial marketing through personal willpower alone is unrealistic.

Regulation can therefore complement personal responsibility rather than replace it.

What stronger regulation could look like

There is no single policy that will solve the problem. A more effective approach would involve several measures.

First, governments could strengthen restrictions on advertising and promotion of foods high in fat, salt and sugar. This could include limiting prominent supermarket placements and certain price promotions that encourage people to buy larger quantities than they otherwise would.

Second, clearer food labelling could help consumers understand what they are buying. Front-of-pack nutritional information can make comparisons easier, particularly when shoppers have limited time.

Third, governments could consider taxes on products associated with particularly high levels of added sugar or other nutrients of concern. Evidence from sugar-sweetened beverage policies suggests that pricing measures can influence purchasing behaviour, although such policies should be designed carefully to avoid placing disproportionate burdens on lower-income households.

Fourth, governments could examine how agricultural subsidies and food policies influence the availability and price of ingredients used extensively in highly processed products. Long-term reform may require changes further up the food supply chain, alongside measures that make fruit, vegetables, pulses and other nutritious foods more affordable and accessible.

Regulation should be proportionate

Stronger regulation does not mean treating every UPF as equally harmful.

A balanced approach should recognise that some processed foods can play a useful role in people's diets. For example, packaged foods can be affordable, accessible and convenient for people with limited time or cooking facilities. Some products can also provide useful nutrients.

The objective should therefore be to reduce excessive consumption of nutritionally poor products rather than create an unrealistic expectation that everyone must eliminate all processed foods.

Policy should also be based on strong evidence and regularly evaluated. If a regulation does not produce the intended health benefits, governments should be prepared to change it. If a measure disproportionately affects particular groups, policymakers should consider ways to reduce those effects.

Industry concerns should be heard, but not allowed to dominate

Food manufacturers have legitimate interests in protecting their businesses, and governments should listen to industry concerns when developing regulation. Businesses need clear rules, reasonable implementation periods and consistent standards.

However, consultation should not become a mechanism for indefinitely delaying public health measures.

There is a broader lesson from tobacco, alcohol and other areas of public health. Industries whose commercial interests are affected by regulation may strongly oppose new rules. That opposition does not automatically mean that regulation is wrong. It means policymakers need transparent evidence, robust legal frameworks and safeguards against excessive influence.

Litigation and lobbying should not determine whether governments can act to protect public health.

Consumers deserve a healthier food environment

The debate about ultra-processed foods can easily become polarised. One side can portray UPFs as inherently toxic, while the other can dismiss concerns as an attack on consumer freedom. Neither position is particularly helpful.

A more sensible approach recognises that food is both a personal choice and a public health issue.

People should remain free to enjoy treats and convenience foods. At the same time, they should not have to navigate an environment in which less nutritious products are systematically cheaper, more heavily promoted and more visible than healthier alternatives.

The goal of stronger regulation should therefore be simple: change the conditions surrounding food choices rather than dictate every individual choice.

A practical path forward

Governments can begin with relatively targeted measures. They can restrict aggressive promotions of foods with poor nutritional profiles, improve labelling, regulate marketing aimed at children and encourage healthier options in schools and public institutions. They can also invest in policies that make nutritious foods more affordable.

None of these measures will eliminate obesity, diabetes or other diet-related illnesses overnight. But public health rarely depends on a single dramatic intervention. Small changes, implemented consistently and evaluated properly, can gradually reshape behaviour and markets.

The growing evidence surrounding ultra-processed foods provides sufficient reason to take the issue seriously. It does not justify panic, nor does it mean every packaged product should be treated as dangerous. It does justify stronger action to reduce excessive consumption of nutritionally poor products and to create a food environment that supports healthier decisions.

Ultimately, regulation should not be about removing choice. It should be about making choice fairer.

Consumers cannot make genuinely informed decisions if important information is difficult to understand, healthier food is less accessible and commercial marketing continually pushes products designed for maximum convenience and appeal.

Stronger regulation, combined with better public information and greater access to nutritious food, offers a more balanced response. It respects individual freedom while recognising that governments have a responsibility to protect public health.

The question is therefore not whether people should be allowed to eat ultra-processed foods. They should.

The more important question is whether society should continue allowing the food environment to encourage excessive consumption of them when evidence increasingly suggests that doing so carries significant health costs.

On that question, stronger and proportionate regulation is increasingly difficult to dismiss.
