Introduction

As students head off to university, ready to thrive on a diet of instant noodles and sugary cereals, Prof. Carlos Augusto Monteiro—the first doctor to raise alarms about ultra-processed foods (UPFs)—is advocating for significant changes in food policy, including the controversial suggestion of a tax on instant noodles and even popular ice cream.

The Call for Government Intervention

Monteiro, a leading figure at São Paulo University in Brazil, emphasizes that the overwhelming evidence linking UPFs to health problems is a clarion call for immediate government intervention. He warns that procrastinating action could have dire consequences for public health, particularly as chronic diseases rise globally.

Nova Classification System

His research on food processing has led to the development of the Nova classification system, which categorizes foods based on their level of processing. At one end are unprocessed foods, such as fresh fruits and vegetables, while at the other are ultra-processed products laden with additives, artificial flavors, and unhealthy fats—think soft drinks, packaged snacks, and yes, those instant noodles that students live on.

The Dangers of Ultra-Processed Foods

Despite criticism that the category of UPFs is vague, Monteiro underlines the dangers they pose. 'We must look beyond technical definitions and scrutinize all food groups that are likely to be ultra-processed,' he asserts. Products like reconstituted meats and most ice cream on the market fall squarely in this risky category, with Monteiro noting that up to 99% of ice cream available in the UK is ultra-processed.

Statistics on Obesity

The urgent message comes in light of troubling statistics: Brazil is projected to see 68% of its adult population classified as overweight or obese by 2030—a sharp rise from today's 62%. Monteiro is calling on governments to treat UPF manufacturers in a manner akin to tobacco companies, demanding health warnings on packages and the imposition of taxes to deter consumption.

Research Linking UPFs to Health Issues

Recent studies have reinforced Monteiro's claims, with a staggering 62 out of 70 cohort studies linking UPF consumption to various health issues, including obesity, diabetes, cardiovascular diseases, and even mental health disorders. This body of research presents a compelling case for action, reminiscent of the evidence that once connected smoking to lung cancer.

A Global Convention for UPFs?

Monteiro's vision extends to the establishment of a global convention targeting UPFs much like the treaties that govern tobacco. While he acknowledges the complexity of diet compared to the straightforward effects of smoking, he firmly believes that both industries contribute to serious health risks and are dominated by powerful multinational corporations.

Guidelines and Restrictions

He argues that national dietary guidelines should discourage the consumption of UPFs, noting that even a seemingly healthy diet can be compromised by their inclusion. This highlights the need for comprehensive measures that include not just guidelines, but also taxation and marketing restrictions aimed at ultra-processed foods.

Tax Reforms in Brazil

In Brazil, Monteiro is advocating for tax reforms that would lower taxes on minimally processed foods while imposing higher taxes on UPFs—an initiative aimed at promoting healthier eating habits.

Concerns About Impact on Lower-Income Communities

While some argue that increased taxes could disproportionately affect lower-income groups, Monteiro counters that UPFs are generally cheaper. The solution lies in bolstering the supply of fresh produce in underserved neighborhoods, enabling all communities to access healthier food options.

Moderation, Not Elimination

Despite the controversy surrounding the taxation of food items, Monteiro asserts that we need not outlaw ultra-processed foods altogether—just as we don't ban tobacco or alcohol. The key is promoting healthier diets while recognizing the stark reality that many traditional food cultures have been undermined by the rise of ultra-processed options.

Global Consumption Trends

As Monteiro notes, countries like the US and UK already see UPFs account for a staggering 66% of their adolescents' energy intake. In contrast, many developing nations are witnessing a rapid uptick in UPF consumption, leading to increased chronic illnesses and healthcare costs that are unsustainable.

Personal Reflections

In a personal reflection, Monteiro admits that consuming UPFs is a rarity for him, highlighting the challenges even health experts face in avoiding these highly palatable yet detrimental foods.

Conclusion

Ultimately, the conversation around instant noodles and other ultra-processed foods is more than just about diet—it's a critical public health issue that needs immediate attention.
