The paper from the University of Göttingen and ProVeg International calls for a fundamental rethink of how nations design their dietary guidelines — making them not only healthier, but also more inclusive, sustainable, and culturally relevant.
A global review of over 100 national dietary guidelines reveals critical gaps in how governments communicate advice on protein, meat, and plant-based diets.
Despite mounting evidence linking high meat consumption with health and climate risks, most guidelines continue to centre animal proteins while offering little clear, practical guidance on plant-based options. In this context, Food-Based Dietary Guidelines (FBDGs) have become one of the most powerful, yet underused, tools in global health and sustainability policy.
Published in the Proceedings of the Nutrition Society (2025), the study by Anna-Lena Klapp, highlights a pressing need for dietary recommendations that reflect modern nutrition science, environmental realities, and the cultural shift towards plant-forward eating.
Five Gaps Holding Back Global Dietary Progress
The analysis identifies five major shortcomings in current national guidelines:
- Outdated food group classifications.
Many FBDGs still separate “meat and dairy” as essential food groups, neglecting plant-based protein sources. Inclusive approaches, such as those adopted by Canada and the Netherlands, show how pulses, nuts, tofu, and dairy alternatives can sit side-by-side with animal products. - Lack of clear limits on animal-sourced foods.
Despite well-established evidence linking high meat intake to chronic disease and environmental impact, few countries set quantitative limits. Newer models — such as Germany’s and Finland’s — now cap weekly meat portions and encourage legumes as climate-smart replacements. - Insufficient guidance on plant-derived nutrients.
Around 40% of guidelines omit plant-based sources of key nutrients such as iron, calcium, and zinc. Klapp highlights the need to spotlight traditional food preparation techniques (like soaking, fermenting, and pairing with vitamin C) that improve nutrient bioavailability — knowledge long embedded in many food cultures. - Limited inclusion of plant-based alternatives.
With consumer demand for dairy and meat alternatives rising globally, guidelines must evolve to address their role, nutritional quality, and fortification needs. The Netherlands leads by setting nutritional standards for plant-based substitutes, ensuring they meet health benchmarks while supporting sustainability goals. - Missing advice for vegetarian and vegan diets.
Sixty percent of FBDGs still fail to provide guidance for vegetarian or vegan diets — despite 1.5 billion people following them worldwide. Well-planned plant-based diets are proven to be nutritionally adequate and protective against chronic disease, yet most official documents either overlook or warn against them.
A Call for Socioecological Thinking
Klapp’s proposed socioecological framework redefines how we think about dietary advice — recognising that food choices are shaped not only by biology and environment, but also by ethics, religion, culture, and economics. In other words, eating is not just personal — it’s deeply social and planetary.
This broader lens invites policymakers to design dietary guidelines that reflect real-world diversity, while empowering individuals to make sustainable, healthy choices within their cultural context.
Why This Matters
The timing of this report is significant. In November, governments will meet at COP30 in Belém to discuss food systems and climate, while the updated EAT–Lancet Planetary Health Diet is set to re-emphasise the importance of reducing animal protein to safeguard planetary and population health.
Some countries—such as Germany, Austria, Finland, and Norway—have already modernised their guidelines to give more space to plant-based foods. But globally, the pace of change is slow, and messaging remains fragmented.
The authors argue that simple, food-focused advice (e.g., “choose tofu over red meat”) is more actionable for the public than abstract nutrient-based recommendations like “reduce saturated fat.”
Nutricomms Opinion
We see this study as a wake-up call for policymakers and public health communicators. Dietary guidelines are one of the most trusted sources of nutrition advice—but without clarity, inclusivity, and cultural relevance, they risk losing authority to less reliable online sources.
Three lessons stand out:
- Shift from risk to empowerment: Instead of warning consumers about deficiencies, guidelines should show how diverse, plant-based diets can meet nutrient needs and support health.
- Balance the UPF narrative: Not all processed foods are created equal—communication must distinguish between low-nutrient snacks and fortified, fibre-rich plant-based alternatives.
- Integrate sustainability into everyday advice: Clear, practical recommendations to reduce red meat and dairy align both public health and climate goals.
The opportunity is clear: modernised, plant-forward guidelines can deliver triple wins—better health, lower emissions, and more resilient food systems. But to achieve this, governments must evolve beyond outdated food groupings and risk-focused messaging, and instead provide inclusive, empowering, evidence-based guidance for all eaters.
