Critical examination of veganism: opportunities and challenges
A critical examination of veganism should take into account both opportunities and challenges. A well-planned vegan diet can be balanced and provide environmental benefits. At the same time, possible nutrient gaps, individual life situations and different ethical perspectives must be taken seriously. The aim is to provide a differentiated view rather than a one-sided defense or rejection.
Veganism: definition and motivations
Veganism is often understood as a way of life that aims, as far as practical, to avoid exploitation and cruelty towards animals. People decide to do this for different reasons: ethical convictions, environmental and climate protection motives, health concerns or a combination of these motives.
The vegan diet is just one part of a more comprehensive lifestyle. A plant-based diet is not automatically vegan, and a vegan diet is not automatically balanced.
Health opportunities and challenges
A well-planned vegan diet can be rich in vegetables, fruits, legumes, whole grains, nuts and seeds. In studies, such diets are often associated with higher fiber intake and more favorable levels of certain cardiometabolic risk factors. The Academy of Nutrition and Dietetics concluded in its position published in 2025 that appropriately planned vegan diets for adults can be nutritionally appropriate and provide long-term health benefits.
At the same time, certain nutrients must be specifically taken into account. Vitamin B12 must be reliably supplemented. Depending on the food choice and individual situation, iodine, calcium, iron, zinc, vitamin D, selenium and long-chain omega-3 fatty acids also deserve attention. A vegan diet is therefore not automatically healthy or deficient - its quality depends on planning and implementation.
Ecological opportunities and conflicting goals
The environmental impacts of food vary considerably. On average, many plant-based foods have lower greenhouse gas emissions and require less land than animal products, particularly beef and lamb. A more plant-based diet can therefore help reduce environmental pollution.
However, a general assessment of individual foods does not make sense. Cultivation, deforestation, irrigation, transportation, cooling, processing and regional conditions all play a role. Plant monocultures or poorly regulated supply chains can also cause ecological and social problems.
Ethics and Philosophy: Which interests count?
A central ethical argument of veganism relates to the ability of animals to experience pain and other sensations. This leads to the demand that their interests should not be given less weight simply because of their species affiliation. In animal ethics, different approaches are discussed, including utilitarian considerations to avoid suffering, rights and duty ethics, and relational approaches.
Critical questions concern the balancing between human interests and animal interests, the use of animals in different cultural and ecological contexts and the practical feasibility of a lifestyle that is as free from exploitation as possible.
Diverse expert opinions
Different perspectives can help you check your own point of view and avoid selective information searches. The two videos from your original post will remain as impulses for discussion. They are individual expert perspectives and should not automatically be understood as a final scientific consensus.

Conclusion
Veganism offers health, ecological and ethical opportunities, but is not a concept that automatically leads to optimal results without knowledge and reflection. A balanced vegan diet requires a reliable supply of vitamin B12 and attention to other potentially critical nutrients. Ecologically, plant-based diets are often beneficial on average, while specific impacts depend on production and supply chain. Ethically, the question of the moral status and interests of non-human animals remains central.
