Vegan
A vegan diet excludes foods derived from animals, including meat, fish, dairy products, eggs, and usually honey. Veganism can also describe a broader ethical lifestyle, but in sports nutrition the term normally refers to the eating pattern. A vegetarian diet is less restrictive because it may include eggs or dairy products.
Vegan eating can support strength training and muscle growth when it provides enough energy, protein, and essential nutrients. Useful protein sources include legumes, tofu, tempeh, textured soy protein, seitan, peas, grains, nuts, seeds, and plant-based protein powders. Individual plant proteins differ in digestibility and amino-acid profile, but varied foods eaten across the day can complement one another; every meal does not need a formally "complete" pairing. Slightly larger portions or a blend of protein sources can be practical when a food is relatively low in one essential amino acid.
Reliable vitamin B12 provision is non-negotiable. A suitably dosed supplement is generally required; fortified foods can contribute, but unfortified plant foods are not a dependable source. Depending on food choices and individual circumstances, vitamin D, iodine, calcium, iron, zinc, selenium, riboflavin, and long-chain omega-3 fats may also deserve attention. A supplement is not automatically needed for every one of these nutrients; intake and, where appropriate, laboratory assessment should guide the decision.
The German Nutrition Society's current position states that a health-promoting vegan diet is possible for healthy adults when vitamin B12 is supplemented, the diet is balanced and well planned, and potentially critical nutrients are covered. Evidence is less certain for pregnancy, breastfeeding, childhood, adolescence, and older age, so these groups require particularly careful planning and qualified advice.
There is no single vegan menu. A pattern based mainly on legumes, whole grains, vegetables, fruit, nuts, and seeds differs nutritionally from one dominated by sweets, refined starches, and convenience foods. The vegan label describes what is excluded; it does not by itself establish diet quality, calorie intake, or suitability for a training goal.
