Executive Summary

Swiss retail chains aggressively market "high-protein" products as a health trend—from yogurt to chocolate bars. Simultaneously, data from the Federal Food Safety Office (BLV) from the menuCH nutrition survey shows that the Swiss population on average already consumes more protein than the official recommendation of 0.8 g/kg body weight. The industry charges markups of 50 to 339 percent for these value-added products. Professional societies and nutrition experts criticize the marketing message as misleading, since healthy adults do not require additional protein consumption.

The protein hype reveals a fundamental market logic: while the organic segment shrinks, retailers create new profit margins through label repositioning of existing products. BLV data from the menuCH survey show a critical mismatch between marketing target audience (young, fitness-oriented consumers) and actual nutritional needs (older people, of whom almost 50% of those over 65 are undernourished). This raises questions about transparency obligations and margin policy—a field that has barely been regulated so far.

Detailed Summary

Market Development and Legal Framework

Protein products have risen from niche segment to mainstream category. Between 2018 and 2025, Migros, Coop, Aldi, Lidl, and Emmi expanded their product ranges many times over; Emmi reports double-digit percentage growth in the Energy Milk segment while the overall yogurt market shrinks. Legally, a product needs at least 20 percent of total energy content from protein to be labeled "high protein," 12 percent for "protein source." These thresholds are naturally reached by fat-free quark (11–13 g/100 g), lentils (9 g), eggs (13 g), or lean fish (18–22 g). In highly processed products—protein breads, bars, drinks—protein concentrate from whey, wheat, soy, or lupines is added. The result: highly processed foods with similar or more calories than the original, but at significantly higher prices.

Epidemiological Reality: Oversupply Instead of Deficiency

BLV analysis of menuCH shows that Swiss women consume on average 1.10 g protein per kg body weight, men 1.23 g—both values exceed the SGE recommendation of 0.8 g/kg for healthy adults. However, averages conceal relevant variation: 26.8% of the population fall below the recommendation. The situation is particularly striking for those over 65: 48.5% of women and 51.8% of men consume too little protein despite increased needs (1.0 g/kg for sarcopenia prevention). Meanwhile, 4.5% consume more than 2 g/kg—an amount that according to BLV can cause kidney damage with chronic intake. In other words: a supply gap exists, but it does not affect the marketing's target audience.

Professional Consistency: An Unexpected Consensus

Across Swiss and German professional societies, a remarkably uniform picture emerges. Nadia Leuenberger (BFH) describes high-protein products as unnecessary for healthy adults; Stéphanie Bieler (SGE) confirms that the Swiss food pyramid already leads to oversupply without these products. The German Society for Nutrition (DGE) illustrates this concretely: three to four slices of whole grain bread, a quarter liter of milk, a cup of yogurt, potatoes, and a piece of fish yield around 60 grams of protein—already double the daily requirement of a 60-kilo woman. Soraya Laurenza (CSS) and Doc Esser (WDR) emphasize that with varied diet, needs are met "without difficulty"; "shakes and bars" are useful at most with "intense strength training."

Price Architecture: 50 to 339 Percent Markup

Consumer magazines Kassensturz (SRF) and K-Tipp documented significant price differences:

  • Snickers High Protein (Lidl): 339% more expensive than the classic version
  • Aldi protein-enriched mozzarella: over 100% premium
  • Emmi Energy Milk High Protein: around 60% premium versus standard version
  • Coop High-Protein Milk: 2.50 CHF/liter vs. 1.55 CHF for regular milk

Retailers justify the differences with "higher processing costs" and additional expenses. Consumer protectionists like Josianne Walpen (Foundation for Consumer Protection) instead speak of a strategy to expand margins under the "pretext of promoting health." Marketing expert Stefan Vogler confirms that manufacturers deliberately test what premium for health-connotated products is achievable.

The Downsides: Sugar, Additives, Health Risks

A second contradiction lies in the health claim itself. The German foundation Stiftung Warentest found that some protein breads contain more calories than their non-enriched originals. In addition, there are additives, sweeteners, and sometimes considerable sugar quantities in drinks and bars. Nutritionist Ioana Chelemen (Watson, July 2025) warns that many of these products are heavily processed and contain little fiber or micronutrients. From a medical perspective, professional societies document two risks:

  1. Kidney Function: With chronic intake of over 2 g/kg body weight, harmful effects on the kidneys cannot be excluded; with pre-existing damage, deterioration is likely.
  2. Insulin Sensitivity: A study by the German Institute for Nutrition Research (DIfE) showed reduced insulin sensitivity in overweight individuals under very high protein intake—a Type 2 diabetes risk factor.

Conclusion: For healthy adults, high-protein products are health-neutral to irrelevant; for people with pre-existing kidney or diabetes conditions, they can be disadvantageous.

Natural Alternatives: Cheaper and More Effective

Those who source protein from domestic sources find cost-effective options without "high-protein" labels: fat-free quark (11–13 g/100 g), Skyr (similar), eggs (13 g), cooked lentils (9 g), tofu (12–15 g), chickpeas (8 g), lean fish (18–22 g), poultry (23 g), hard cheese like Sbrinz or Gruyere (up to 28 g/100 g). A slice of Appenzeller provides around 10 grams of protein already. Plant-based options include oats, quinoa, buckwheat, and legumes; combined with grains or dairy products, biological value increases. An older person or athlete with increased needs can meet them at a fraction of the cost of a protein powder or shake using standard foods.

Key Findings

  • The Swiss population already exceeds the SGE recommendation of 0.8 g/kg body weight on average without high-protein products.
  • The legal threshold of 20% energy content for "high protein" is already reached by many unprocessed foods like lentils or fat-free quark.
  • Documented markups range from 50 to 339 percent; the highest difference is shown by the Snickers version at Lidl.
  • The only clearly identifiable supply gap affects people over 65 years (almost 50% undernourished), whom marketing least reaches.
  • Chronically high protein intake (over 2 g/kg) carries documented risks for kidney function and insulin sensitivity; caution is warranted in pre-existing conditions.
  • Professional societies (SGE, BFH, DGE) are unusually unanimous: these products are not required for healthy adults.

Critical Questions

  1. Data Quality and Transparency: On what detailed calculation basis do Migros, Coop, and Emmi justify the documented markups—do transparent, independently verifiable statements on "processing and development costs" exist, or is pricing based on "pricing-to-willingness-to-pay"?

  2. Conflicts of Interest and Independence: How independent are nutrition-related recommendations in retailers' in-house publications or in industry co-financed studies—do conflicts of interest exist in the evaluation of protein products?

  3. Causality and Market Mechanisms: What portion of documented consumption growth (2018–2025) is attributable to actual changed needs, and what to marketing, social media influencer campaigns, and packaging psychology?

  4. Counter-Hypothesis and Economic Viability: Why is a comparably intensive marketing offensive for natural protein sources (lentils, Skyr, eggs, hard cheese) not conducted to the same extent—are these not economically viable, or is there a deliberate focus on highly processed, higher-margin products?

  5. Consumer Information and Feasibility: How could packaging labeling be improved so consumers can grasp the actual added value of an enriched product versus the unprocessed comparison product in under 10 seconds?

  6. Risk Responsibility: What responsibility do retailers bear in marketing confectionery (chocolate bars, pudding) as "healthy"—particularly considering children and adolescents, whose protein consumption according to menuCH-Kids is already reported as high?

  7. Regulatory Gap: Should the BLV introduce a binding, transparent comparison value for the claim "protein-rich" that discloses measurable added value versus the unprocessed reference product?

  8. Distributive Justice: If the only epidemiologically relevant supply gap affects the older population—why is market supply aimed almost exclusively at young, wealthy, fitness-oriented consumers instead of seniors who would actually benefit?
