What if one of Indonesia's important future health interventions happens long before someone enters a hospital?

Indonesia's health system is dealing with a changing disease burden as lifestyles, cities and food consumption change.

Increasingly, the issue is not only infectious disease or access to medical treatment.

It is prevention.

In January 2026, WHO highlighted Indonesia's efforts to strengthen regulations addressing unhealthy food consumption, including measures concerning nutrition labelling, advertising, ingredients associated with non-communicable disease risks, healthier food environments and the possibility of fiscal measures.

Sugar — and particularly sugar-sweetened beverages — is part of this discussion.

But reducing the issue to "Indonesians consume too much sugar" risks missing the bigger picture.

People make choices inside environments

Consumers do not make food decisions in isolation.

What people eat and drink is shaped by:

That becomes particularly important for children.

A consumer-awareness campaign telling people that too much sugar is unhealthy may be useful, but information alone is unlikely to transform an environment where unhealthy choices remain inexpensive, convenient, heavily promoted and culturally normalised.

This is why the more interesting opportunity is not necessarily sugar reduction.

It may be healthier food environments.

Prevention creates a much broader innovation space

Once we frame the challenge that way, many possible interventions appear.

This also creates an important role for communications.

Public-health messaging fails when it sounds judgmental or detached from daily reality.

Telling families to make healthier choices without considering affordability, convenience and cultural food practices can easily become ineffective — or patronising.

The objective should not be to demonise sugar, food companies or consumers.

It should be to make healthier choices easier, understandable and realistically available.

What role could European organizations play?

This is an area where international organizations could potentially contribute research, behavioural science, nutrition expertise, school-based prevention models, responsible-marketing frameworks, product innovation or evaluation.

But again, solutions need localisation.

A European nutrition campaign copied into Bahasa Indonesia does not become an Indonesian programme simply because it has been translated.

Food is cultural. Family structures matter. Religious practices matter. Price matters. Street-food culture matters. Digital behaviour matters. Trust in different information sources matters.

The intervention has to begin with understanding how Indonesians actually experience the food environment.

The opportunity is early intervention

Preventive health can also be difficult politically and commercially because the benefit often appears years later.

There is no dramatic moment when a successful prevention programme can point to one person and say: "We prevented diabetes today."

But collectively, small behavioural and environmental changes can potentially influence future disease burden.

That is why Indonesia's evolving food-policy environment deserves attention now.

The strategic question is not simply: How do we make Indonesians consume less sugar?

How do we create conditions in which healthier choices become easier before today's consumption patterns become tomorrow's much larger public-health burden?

That opens a far more constructive conversation — one involving government, researchers, schools, families, companies, NGOs and consumers.

And perhaps that is where the real opportunity lies.
