Adopting a vegan diet has become increasingly popular in recent years, with more people recognizing its potential health, environmental, and ethical benefits. A vegan diet excludes all animal products, including meat, dairy, eggs, and often honey, focusing instead on plant-based foods like fruits, vegetables, grains, nuts, and legumes.
A vegan diet is a way of eating that excludes all animal-derived foods, including meat, fish, dairy products and eggs. Instead, it focuses on nutrient-rich plant foods such as fruits, vegetables, wholegrains, legumes, nuts and seeds. When carefully planned, a vegan diet can support good health, in line with NHS guidance on the vegan diet, while offering environmental and ethical benefits.
A vegan diet is a plant-based eating pattern that excludes all foods derived from animals. Unlike some other diets, it avoids meat, poultry, fish, seafood, dairy products, eggs and, for many people, honey. Instead, meals are based on foods such as vegetables, fruits, beans, lentils, wholegrains, nuts and seeds.
People choose to follow a vegan diet for many different reasons. Some are motivated by the potential health benefits, while others wish to reduce their environmental impact or avoid using animal products for ethical reasons.
When properly planned, a vegan diet can provide most of the nutrients your body needs and may contribute to long-term health and wellbeing.
Although vegan and vegetarian diets are both plant-focused, there are important differences between them.
Both diets can be nutritious when carefully planned. However, people following a vegan diet need to pay particular attention to nutrients such as vitamin B12, calcium, iodine and omega-3 fatty acids, which are more commonly found in animal products.
A healthy vegan diet includes a wide variety of plant-based foods that provide essential vitamins, minerals, fibre and protein.
Examples include:
Eating a colourful variety of foods helps ensure you receive a broad range of nutrients while making meals enjoyable and satisfying. Many of these foods, particularly wholegrains, beans and lentils, are also naturally high in fibre; our guide to high-fibre foods explains why that matters for digestive health.
People following a vegan diet avoid foods and ingredients that come from animals.
These include:
Many vegans also choose to avoid honey and products containing animal-derived additives. Reading food labels can help identify ingredients that may not be suitable for a vegan diet.
With a clear idea of what a vegan diet includes and excludes, it's worth looking at the benefits it may offer:
A well-planned vegan diet can support good health and may help reduce the risk of several chronic conditions. Diets rich in vegetables, fruits, legumes and wholegrains are associated with improved heart health, healthy cholesterol levels and better weight management.
However, a vegan diet requires careful planning to ensure adequate intake of essential nutrients. Without appropriate food choices, some people may become deficient in vitamin B12, iron, calcium, iodine or vitamin D.
Choosing a wide variety of plant-based foods and, where appropriate, using fortified foods or supplements can help ensure your nutritional needs are met.
Most nutritional needs can be met through a varied vegan diet, as confirmed by the British Dietetic Association, although some nutrients deserve particular attention.
Vitamin B12 is especially important because it is naturally found almost exclusively in animal products. Most people following a vegan diet are advised to consume fortified foods or take a vitamin B12 supplement. If you're ever unsure whether you're getting enough, a private blood test can check your levels of vitamin B12, iron, vitamin D and other key nutrients.
A vegan diet can provide excellent nutrition when carefully planned. However, eliminating animal products without replacing key nutrients may increase the risk of nutritional deficiencies.
Potential concerns include:
These risks can usually be avoided through balanced meal planning, fortified foods and supplements where recommended by a healthcare professional.
Although a vegan diet can be suitable for many people, some individuals should seek personalised nutritional advice before making significant dietary changes.
This includes:
A GP or registered dietitian can help ensure your diet provides all the nutrients needed for good health.
A vegan diet offers a wide range of benefits, from improved heart health and better weight management to environmental sustainability and ethical considerations. While transitioning to a vegan diet can seem challenging at first, the long-term health benefits and positive impact on the planet make it a worthwhile choice for many people. As with any diet, it's important to plan your meals carefully to ensure you're getting all the necessary nutrients. Consulting with a healthcare provider or a nutritionist can help you make a smooth transition and maintain a balanced, nutritious vegan diet.

Yes. Protein can be obtained from beans, lentils, tofu, tempeh, chickpeas, quinoa, nuts and seeds. Eating a varied diet throughout the day usually provides enough protein for most healthy adults.
Vitamin B12 is naturally found in animal products, so many people following a vegan diet require fortified foods or a vitamin B12 supplement to meet their nutritional needs.
Vegans can eat fruits, vegetables, wholegrains, legumes, tofu, tempeh, nuts, seeds, plant-based milk alternatives and many fortified foods.
A vegan diet excludes meat, poultry, fish, seafood, dairy products, eggs and other animal-derived ingredients such as gelatine. Many vegans also choose to avoid honey.
A vegan diet may support weight management because many plant-based foods are naturally high in fibre and lower in calories than animal products. Maintaining a healthy weight still depends on overall calorie intake, portion sizes and physical activity.
Research suggests that diets rich in vegetables, fruits, legumes and wholegrains may help lower cholesterol, improve blood pressure and reduce the risk of heart disease.
Vegetarians avoid meat and fish but may still eat dairy products and eggs. Vegans avoid all animal-derived foods, including dairy, eggs and, for many people, honey.
Children can follow a vegan diet if it is carefully planned to provide enough energy, protein, vitamins and minerals. Parents should seek advice from a healthcare professional or registered dietitian to ensure healthy growth and development.
Many vegans benefit from vitamin B12 supplementation. Depending on individual dietary intake and lifestyle, vitamin D, iodine and omega-3 supplements may also be recommended.
Start by gradually replacing animal products with plant-based alternatives, planning balanced meals and ensuring adequate intake of key nutrients. Speaking to a healthcare professional or registered dietitian can help make the transition easier and nutritionally balanced.
