Misleading immune claims: A dangerous game with public health
In the cold season, when waves of colds sweep across Austria, many people reach for supposedly healthy foods that are said to boost the immune system. But an alarming study by Foodwatch e. V. shows that many of these products are more appearance than substance. Our health is put at risk while manufacturers increase their sales with clever marketing and misleading packaging.
What is really in these "immune products"?
Foodwatch identified around 50 products in its research that use terms like "immune protection", "immune-fit" or "vitamin power" to court consumers. But appearances are deceptive: many of these products are real sugar bombs. A single glass of some of these drinks already contains more sugar than the World Health Organization (WHO) recommends for an entire day. Instead of strengthening the immune system, they promote overweight, diabetes and other health problems.
A look at the history: How this came about
The idea of labeling foods with health claims is not new. For decades manufacturers have used this tactic to make their products more attractive. But the European Union has actually set clear limits with the Health Claims Regulation: only scientifically proven health claims approved by the European Food Safety Authority (EFSA) are permitted. So how do such products then make it onto the shelves?
The packaging trick
Manufacturers use creative packaging designs and bold colors to create the impression that their products could strengthen the immune system. Terms like "immune booster" or "good for your immune system" suggest an effect that is not proven. This leads to massive consumer deception.
The legal situation: What the courts say
There are already several court rulings that classify such advertising claims as unlawful. In July 2025 the Karlsruhe Regional Court ruled in favor of Foodwatch Germany in a case against dm. The well-known juice producer Eckes-Granini was also convicted for misleading advertising. Another suit against Voelkel is still pending.
Foodwatch's demands
- Ban on misleading terms: Terms like "immune booster" must not be used if the effect is not proven.
- Stricter controls: Authorities must carry out systematic checks and consistently punish violations.
- Introduction of the Nutri-Score: A clear labeling system must also be introduced in Austria to make sugar bombs easy to recognize.
Indra Kley-Schöneich of Foodwatch Austria emphasizes: "These tricks of the food industry are an attack on our health and our right to honest information."
The impact on consumers
The average consumer relies on the information on labels and trusts that products advertised as healthy are actually good for health. But reality looks different. Many people unknowingly consume large amounts of sugar, which can lead to long-term health problems.
A comparison with other countries
In some European countries such as France and the Netherlands, the Nutri-Score is already established. This simple, color-coded labeling helps consumers make healthier choices. Austria lags behind here and could learn from these examples.
A look into the future: What awaits us?
The discussion around misleading health claims will certainly continue. With increasing pressure from consumer organizations like Foodwatch and growing public awareness, there could soon be stricter regulations and better labeling. Until then, it is important that consumers remain critical and inform themselves carefully.
Indra Kley-Schöneich demands: "Policymakers must finally stop misleading immune advertising — and protect consumers through clear labeling."
What can you do?
- Inform yourself: Use independent sources and organizations like Foodwatch to learn about the true ingredients of food products.
- Read the labels: Pay attention to the ingredient list and sugar content.
- Demand clear labeling: Support initiatives that campaign for better food labeling.
It is in our hands to hold manufacturers accountable and fight for a healthier future.
