Can you get enough protein on a vegetarian or vegan diet?
Yes, most people can get enough protein from a vegetarian or vegan diet. The key is to eat a varied mix of protein-rich foods throughout the day. You do not need meat at every meal to meet your needs.
Protein helps build and repair tissues, supports muscle health, and plays an important role in the immune system. In the UK, adults generally need around 0.75g of protein per kilogram of body weight each day. For a 70kg adult, that works out at about 52g a day.
Good protein sources for vegetarians and vegans
Vegetarians can get protein from dairy foods such as milk, yoghurt, and cheese, as well as eggs. Plant-based options include beans, lentils, chickpeas, tofu, tempeh, nuts, seeds, and soya drinks. Wholegrains like oats, quinoa, and wholemeal bread also add to your intake.
Vegan diets can provide plenty of protein too, especially when meals include pulses and soya foods. Tofu, edamame, lentil pasta, and pea-protein products are all useful choices. Even snacks such as hummus with pitta or peanut butter on toast can contribute.
Do you need to combine foods?
It is no longer thought necessary to combine specific foods at every meal to make a “complete” protein. Eating a range of plant proteins across the day is usually enough for most healthy adults. Variety is more important than perfect food pairing.
For example, having porridge with nuts at breakfast, a lentil soup at lunch, and tofu stir-fry at dinner can easily build a good protein intake. If you eat enough calories overall, protein is usually easier to meet than people expect. This is especially true if you include pulses, soya, and nuts regularly.
When to pay extra attention
Some people may need more protein, including older adults, people recovering from illness, and those who are very active. Pregnant and breastfeeding women also need to plan meals carefully. In these cases, it can help to include a protein source at every meal and snack.
Children and teenagers on vegetarian or vegan diets should also eat a wide variety of foods. A dietitian or GP can offer advice if you are worried about meeting your needs. Fortified foods and supplements may sometimes be helpful, but protein itself is usually achievable through food alone.
Simple ways to boost protein intake
Try adding beans to soups, salads, curries, and pasta dishes. Swap regular yoghurt for Greek yoghurt, or choose soya yoghurt if you are vegan. Use nuts and seeds on cereal, porridge, and salads for an easy extra boost.
Planning ahead can make a big difference. Keep tofu, tins of lentils, nut butter, and frozen edamame in the cupboard or freezer. With a little variety, a vegetarian or vegan diet can provide enough protein for good health.

Common mistakes include relying on vegetables alone, eating too few calories, not including legumes or soy foods regularly, and assuming plant proteins are always too low to matter.
Vegetarian or vegan protein intake can be just as effective when total protein and food quality are adequate. Plant-based diets may require more attention to variety, but they can still support health and performance.
Yes, vegetarian or vegan protein intake can be enough for older adults, but they may benefit from slightly higher protein amounts and protein-rich meals spread across the day.
Athletes can manage vegetarian or vegan protein intake by aiming for higher daily protein totals, using soy, legumes, seitan, and protein shakes when needed, and eating protein after training.
Legumes are one of the most important sources of vegetarian or vegan protein intake because they provide substantial protein, fiber, iron, and other nutrients at a low cost.
Vegetarian or vegan protein intake is easier to meet when meals include enough total calories from grains, legumes, starchy vegetables, nuts, seeds, and healthy fats, not just low-calorie vegetables.
