Vegan Checklist
A simple checklist to help you build a balanced vegan diet and stay on track.
Key Components of a Healthy Vegan Diet
A varied, balanced and nutrient-rich plant-based eating pattern
A healthy vegan diet is a varied and well-planned way of eating that excludes all foods of animal origin while providing the energy, protein, vitamins, minerals, essential fats and other nutrients needed for good health.
Adopting a plant-based lifestyle is no longer viewed as a passing trend but rather as a conscious choice that can profoundly influence personal well-being. Increasing scientific research highlights the numerous benefits of a plant-based diet, showing how a plant-based diet can support heart health, aid weight management, and play a role in preventing heart disease. Beyond the physical benefits, understanding the connection between diet and cancer prevention helps explain why many people report feeling more balanced after making the switch.
A vegan diet can be nutritionally adequate when it is built around a wide variety of plant foods, including vegetables, fruit, whole grains, beans, lentils, peas, nuts, seeds and other minimally processed foods. Fortified foods and appropriate supplements also have an important role, particularly for nutrients that can be difficult to obtain reliably from unfortified plant foods.
A healthy vegan diet is not simply a diet without animal products. It is a diet built around a wide variety of nutritious plant foods.
A balanced vegan diet is built around a wide variety of plant foods, including fruit and vegetables, whole grains, beans and lentils, nuts and seeds. These foods provide fibre, protein, healthy fats, vitamins, minerals and other beneficial plant compounds that support overall health. Going vegan does not mean giving up the foods you enjoy. Many familiar meals are already plant-based, while simple ingredient swaps can transform traditional favourites into delicious vegan versions. It is also an opportunity to discover new flavours, ingredients and recipes.
However, being vegan does not automatically make a diet healthy. A diet centred mainly on highly processed foods, such as biscuits, crisps, pastries and vegan convenience foods, may be low in some essential nutrients despite containing no animal products. The key is variety and balance: make minimally processed plant foods the foundation of your diet, include reliable sources of essential nutrients, and enjoy treats in moderation. With a little planning, a vegan diet can be both nutritious and satisfying.
01
Vegetables & Fruit
Leafy greens, colourful vegetables, berries and other whole fruits provide fibre, vitamins, minerals, antioxidants and beneficial plant compounds.
02
Whole Grains
Oats, brown rice, barley, quinoa and wholegrain bread provide complex carbohydrates, fibre, B vitamins, magnesium, zinc and protein.
03
Beans, Lentils & Soy
Beans, lentils, chickpeas, tofu, tempeh and edamame are key sources of protein, iron, fibre and other essential nutrients.
04
Nuts & Seeds
Walnuts, chia, flax, almonds and pumpkin seeds provide healthy fats, plant protein, minerals and ALA omega-3.
05
Healthy Fats
Avocado, tahini, extra virgin olive oil and whole nuts provide unsaturated fats that support heart health and the absorption of fat-soluble vitamins.
06
Fortified Foods
Fortified plant milks, yoghurts and nutritional yeast can provide important nutrients such as vitamin B12, vitamin D, calcium and iodine.
How to Build a Balanced Vegan Plate
Use proportions rather than measurements. This single habit resolves most everyday questions about whether a meal is adequate.
- ½ Vegetables and fruit
- ¼ Whole grains or starchy foods
- ¼ Legumes, soy and protein foods
Don’t forget healthy fats — a small portion with each meal helps absorb fat-soluble vitamins.
A healthy vegan diet is rich in a wide variety of nutrient-dense foods that can help fuel your body, support healthy digestion and strengthen your immune system. It can also contribute to clearer skin, a brighter mood and a greater sense of overall wellbeing.
Feel Fantastic!
Nourish your body from the inside out
A healthy plant-based diet is rich in nutrients that boost energy, aid digestion, support immunity, improve skin, and lift mood. Studies show that those following it generally consume all essential nutrients and enjoy a lower risk of many diseases.
Support Your Heart!
Give your cardiovascular health a helping hand
A plant-based diet is renowned for its cardiovascular benefits. By focusing on fruits, vegetables, whole grains, nuts, and legumes, you naturally reduce saturated fats and cholesterol intake, which can lower blood pressure and improve heart function. Numerous studies have shown that people who follow a plant-based lifestyle have a significantly lower risk of heart disease, helping you maintain a strong and healthy heart for years to come.
Lower Your Cancer Risk!
Fill your plate with protective plant foods
Filling your plate with colourful plant foods means more antioxidants and fibre, which help protect your cells from damage. Studies show that people who follow a plant-based lifestyle are at a reduced risk of certain cancers.
Boost Digestive Health!
Feed your gut with fibre-rich foods
A plant-based diet naturally supports a happy gut. Foods rich in fibre—such as vegetables, fruits, legumes, and whole grains—help regulate digestion, prevent constipation, and nourish beneficial gut bacteria. Over time, this not only improves nutrient absorption but also strengthens your overall digestive wellbeing.
Prevent or Reverse Type 2 Diabetes!
Support healthier blood sugar control
Adopting a plant-based diet can play a crucial role in managing blood sugar levels. By focusing on whole grains, legumes, fruits, and vegetables, you reduce the intake of refined sugars and unhealthy fats, helping to prevent insulin resistance. In some cases, this approach has even been shown to reverse Type 2 diabetes, offering a natural path to better long-term health.
Protect Your Brain!
Nourish your cognitive health
Eating a plant-based diet may help safeguard your cognitive health as you age. Rich in antioxidants, vitamins, and healthy fats, plant foods combat inflammation and oxidative stress, which are linked to memory decline and neurodegenerative diseases. By choosing more vegetables, fruits, nuts, and seeds, you give your brain the nutrients it needs to stay sharp and focused.
Increase Your Energy Levels!
Keep your energy steady throughout the day
A plant-based diet can leave you feeling more energised throughout the day. Whole grains, fruits, vegetables, and legumes provide a steady release of energy, avoiding the crashes often caused by processed foods or high sugar meals. By nourishing your body with nutrient-dense foods, you can maintain vitality and stay active from morning to night.
Age Gracefully!
Support long-term vitality and wellbeing
Embracing a plant-based lifestyle can help you maintain vitality and wellbeing as you grow older. Antioxidant-rich fruits and vegetables combat cellular damage, while healthy fats from nuts and seeds support skin elasticity and joint health. Over time, this approach can contribute to a longer, healthier, and more graceful ageing process.
Breathe Easier!
Give your respiratory health a natural boost
A plant-based diet can support respiratory health by reducing inflammation throughout the body. Diets rich in fruits, vegetables, and whole grains provide antioxidants that help keep airways clear and may lower the risk of asthma and other respiratory issues. By eating more plants, you give your lungs a natural boost and make breathing feel easier.
Maintain a Healthy Weight!
Support sustainable weight management
A plant-based diet makes it easier to achieve and maintain a healthy weight naturally. Packed with fibre-rich foods like vegetables, fruits, legumes, and whole grains, it keeps you feeling full for longer while providing essential nutrients without excess calories. This approach supports sustainable weight management and overall wellbeing.

A practical daily vegan nutrition checklist: what each nutrient does and where a vegan diet reliably provides it.
| Nutrient / food group | Why it matters | Vegan sources |
|---|---|---|
| Protein | Growth, repair, muscle maintenance | Beans, lentils, tofu, tempeh, seitan, soy milk |
| Fibre | Gut and metabolic health | Whole grains, pulses, fruit, vegetables |
| Calcium | Bones, teeth and muscle function | Fortified plant milk, calcium-set tofu, tahini, kale |
| Iron | Blood and oxygen transport | Pulses, whole grains, seeds, dried fruit + vitamin C |
| Vitamin B12 | Blood and nervous system | Fortified foods and a reliable supplement |
| Iodine | Thyroid function and metabolism | Fortified foods or a measured supplement |
| Vitamin D | Bones, muscles and immunity | Fortified foods, supplements, sensible sunlight |
| Omega-3 (ALA) | Brain, eyes and cardiovascular health | Flaxseed, chia, walnuts; algal EPA/DHA supplement |
| Zinc | Immunity and cell function | Legumes, seeds, nuts, whole grains |
| Selenium | Antioxidant and thyroid function | Brazil nuts (in moderation), seeds, fortified foods |
The NHS specifically highlights vitamin B12, calcium, iron, iodine, selenium and vitamin D as the nutrients requiring particular attention on a vegan diet.
Simple, practical swaps that make a vegan diet more nutritious — without overcomplicating your meals.
Remember: Being vegan does not automatically mean eating a healthy diet. A vegan diet centred on whole or minimally processed foods is very different from one that relies heavily on ultra-processed foods and snacks. These simple swaps can help you build a more nutritious, whole-food-focused vegan diet.
A healthy plant-based dietary pattern may support health in several areas, including:
A whole-food vegan diet provides plenty of fibre, fruits, vegetables, whole grains, pulses, nuts and seeds. Compared with Western-style dietary patterns high in meat, saturated fat and highly processed foods, this eating pattern supports healthy blood sugar regulation and insulin sensitivity.
Clinical research shows that dietary changes, particularly alongside regular physical activity, can improve blood glucose control in people with type 2 diabetes. A healthy vegan diet can also support healthy body weight, cholesterol and blood pressure, while helping reduce the risk of diabetes-related complications.
Overall, the evidence suggests that a well-planned whole-food vegan diet can be a valuable approach for preventing and managing type 2 diabetes, and in some cases may contribute to remission alongside other lifestyle changes and medical care.

A healthy plant-based diet provides a wide variety of fibre-rich foods and naturally occurring plant compounds, including polyphenols and carotenoids. Research has associated healthy plant-based dietary patterns with a lower risk of several cancers, including breast, colorectal and liver cancer.
Large observational studies have reported lower overall cancer incidence among vegetarians and vegans. In the Oxford cohort study, cancer incidence was 11% lower among vegetarians and 19% lower among vegans compared with meat-eaters (Key et al., 2014). Other research has also found associations between vegan diets and lower overall cancer risk (Tantamango-Bartley et al., 2013).
Foods such as fruits, vegetables, whole grains, pulses, seeds and soya foods provide fibre and a range of bioactive compounds associated with cancer prevention. Cruciferous vegetables such as broccoli also contain glucosinolates and isothiocyanates, which have been studied for their role in processes related to cancer development.

Vegan diets generally contain less saturated fat and more fibre, while whole plant foods have a lower energy density. This makes it easier to enjoy satisfying portions while supporting a healthy body weight and digestion.
Large studies have found that vegans tend to have lower body weight and lower rates of overweight and obesity than meat-eaters. For example, Rizzo et al. (2013) reported obesity rates of 9.4% among vegans compared with 33.3% among meat-eaters.
Clinical research has also shown that low-fat vegan diets can support weight loss without strict calorie or portion restriction. In one study, participants following a low-fat, low-GI vegan diet lost more weight than those following several other dietary patterns (Turner-McGrievy et al., 2015).

A healthy vegan diet can support heart health when it is centred on vegetables, fruits, whole grains, legumes, nuts and seeds. These foods provide fibre and beneficial plant compounds while typically containing less saturated fat than diets rich in animal foods.
Research has associated vegan and vegetarian dietary patterns with a lower risk of cardiovascular disease. A large meta-analysis found that vegetarian diets were associated with a 15% lower risk of cardiovascular disease and a 9% lower risk of cardiovascular disease mortality compared with non-vegetarian diets (Dinu et al., 2017).
Clinical studies have also found improvements in cardiovascular risk factors among people following plant-based diets, including lower LDL cholesterol, blood pressure and body weight. A well-planned vegan diet, combined with regular physical activity and other healthy habits, can therefore form an important part of a heart-healthy lifestyle.

A well-planned vegan diet can support healthy cholesterol levels by providing more fibre and less saturated fat than many diets based on animal foods. Foods such as oats, whole grains, beans, lentils, fruits, vegetables, nuts and seeds provide nutrients and plant compounds that support healthy blood lipid levels.
A 2023 meta-analysis of 30 randomised controlled trials found that vegetarian and vegan diets reduced total cholesterol, LDL cholesterol and apolipoprotein B compared with omnivorous diets. The average reduction in LDL cholesterol was 0.30 mmol/L (Koch et al., 2023).
Other systematic reviews have also found that vegan diets can reduce total and LDL cholesterol, particularly when they are based on whole or minimally processed plant foods.

A healthy vegan diet can support healthy blood pressure when it is based on vegetables, fruits, whole grains, legumes, nuts and seeds, while limiting excess sodium and highly processed foods. These foods provide fibre, potassium and other nutrients that are important for cardiovascular health.
Research has found lower blood pressure among people following vegan and vegetarian diets. A meta-analysis of 15 randomised controlled trials found that vegetarian diets reduced systolic and diastolic blood pressure, with vegan diets showing an average reduction of 3.12 mmHg in systolic blood pressure (2020).
A separate meta-analysis of 11 randomised trials found that vegan diets did not significantly lower blood pressure overall, but participants who started with elevated blood pressure experienced reductions of about 4 mmHg in both systolic and diastolic pressure. Overall, a well-planned vegan diet can form part of a lifestyle that supports healthy blood pressure.

Nutritional needs change across different stages of life. While a plant-based diet can be healthy at every age, careful planning becomes especially important during certain periods.
Pregnancy
During pregnancy, nutritional needs increase significantly. Careful planning ensures adequate intake of key nutrients for both parent and baby.
Adults
For most adults, a balanced vegan diet can provide all the nutrients needed for long-term health, with attention to key nutrients.
Children
Growing children have specific requirements for energy and nutrients. A well-planned plant-based diet can support healthy growth and development.
Older Adults
Older adults may have changing nutritional needs. Thoughtful meal planning becomes especially important to maintain strength and vitality.
Always consult a healthcare provider or registered dietitian before making significant dietary changes, especially during pregnancy, for children, or if managing a health condition.
