Protein is a cornerstone of nutritional health, indispensable for the building and repair of body tissues such as muscle and skin, as well as for the creation of enzymes and hormones but how much protein do I need?
How Much Protein Do I Need?
In the UK the RNI (Reference Nutrient Intake) is 0.75g of protein per kilo of body weight per day.
However, the daily protein requirement of healthy individuals over 65 years is 1.0–1.2g protein per kilo of body weight.
Individuals with acute or chronic illnesses may need up to 1.2–1.5g protein per kilo of body weight.
If you’re goal is to build muscle then you’re looking at a target of 1.2-1.8g protein per kilo of body weight. according to the International Olympic Committee for strength.
Always consult a health professional before any changes to your diet.
A common misconception is that a vegan diet, which excludes all animal products, may lack sufficient protein.
However, a variety of plant-based foods provide ample protein, which can meet and even exceed daily requirements.
Switching to a vegan diet doesn’t mean sacrificing protein quality or quantity. Plant proteins, once thought to be inferior due to their amino acid profile, are now recognised for their role in a balanced diet. Combining different plant sources can yield a complete amino acid profile, comparable to that of animal proteins.
Innovations in food technology have also expanded the variety of vegan protein sources, making it easier than ever to consume protein-rich vegan foods.
Key Takeaways

Understanding Vegan Protein
Vegan protein is integral in maintaining health on a plant-based diet, ensuring that individuals receive all necessary amino acids through purposeful selection of a variety of protein sources.
Defining Plant-Based Protein
Plant-based protein is derived from various vegan sources such as legumes, grains, nuts, seeds, and vegetables.
Unlike animal protein, plant proteins are often lower in saturated fats and cholesterol, making them a heart-friendly choice for many. For example, legumes like lentils and beans are exceptional sources of protein and are staples in a vegan diet.
Importance of Protein in Vegan Diets
Protein plays a crucial role in the vegan diet as it is vital for building and repairing tissue, supporting enzymatic and hormonal functions, and providing energy.
Due to the absence of animal products, vegans must ensure they receive adequate protein to meet their body’s requirements, which some research proposes to be around 1g per kilogram of body weight, as suggested by The Vegan Society.
Protein Quality and Amino Acid Profile
The quality of protein is determined by its amino acid profile – proteins are made of amino acids, with nine being classified as essential because our bodies cannot synthesise them.
A varied vegan diet can supply all the essential amino acids, though plant-based protein sources may be deficient in one or more essential amino acids. Hence, it is important to consume a diversity of protein-rich plants to ensure a complete amino acid profile.
Incorporating a variety of foods like quinoa, tofu, chia seeds, and spirulina, which contain all essential amino acids, can help in meeting protein intake requirements.
Sources of Vegan Protein

This section will guide the reader through balancing macronutrients, devising meal plans, and exploring supplementation options, with attention to essential nutrients such as vitamin B12, iron, zinc, calcium, magnesium, and potassium.
Balancing Macronutrients
To maintain a balanced diet, individuals must consume adequate amounts of carbohydrates, fats, and proteins. Proteins should be prioritised, as they are the building blocks of the body. One should aim for a high protein intake while also ensuring that other macronutrients are in proper proportion.
Incorporating a variety of protein-rich foods like lentils, beans, and tofu can help achieve this balance.
Meal Planning and Prep
Effective meal planning is crucial for meeting the daily intake of protein. Structured meal planning and prep can help individuals easily incorporate high-protein vegan foods into their diet. Ideas include preparing lentil salads, chickpea soups, or tofu stir-fries.
Adding vegan yoghurt to breakfast or snacks, and using legumes in salads for lunch, can also boost protein consumption. For convenience, making smoothies with fortified plant milks can provide an easy and delicious protein hit.
Supplementation Options
While food sources are preferable, some individuals may turn to supplements to meet their protein and nutrient needs. Vegan protein powders can be added to smoothies and baking for an extra protein boost.
Supplements are also useful for obtaining hard-to-get nutrients like vitamin B12, iron, zinc, calcium, and magnesium. However, it is essential to consult a healthcare professional before starting any supplement regime to tailor the intake based on individual requirements.
Health and Nutritional Considerations
When adopting a vegan diet, it’s crucial to ensure one’s intake of protein and essential nutrients supports overall health and meets individual nutritional demands, without overdoing it.
Meeting Essential Nutrient Needs
Vegan diets can provide all essential amino acids by incorporating a variety of plant-based protein sources such as legumes, nuts, seeds, and whole grains.
However, some nutrients, such as iron, zinc, vitamin B12, calcium, and magnesium, require particular attention as they are less bioavailable in plant sources. For instance, iron found in plant foods is non-heme iron, which the body absorbs less efficiently than the heme iron in animal products.
It is beneficial to consume iron-rich foods, such as lentils and fortified breakfast cereals, with vitamin C-rich foods to enhance absorption.
Individuals should also be aware of omega-3 fatty acid sources, like flaxseeds and chia seeds, which are important for cardiovascular health. The incorporation of vitamin B12 fortified foods or supplements is necessary, as this vitamin is not naturally available in plant foods.
A daily intake of calcium from fortified plant milks, tofu, or green leafy vegetables is also recommended to support bone health.
Considerations for Athletes and Bodybuilders
Athletes and bodybuilders may have higher protein intake requirements to support muscle repair and growth. They might need to consume protein at the upper end of the recommended intake, which is 1.2 to 1.8 (or even more) grams per kilogram of body weight, depending on their level of physical activity.
Key protein sources include soya, pea protein, and seitan, which can be essential in helping to optimise muscle synthesis. Vegan athletes should emphasise a varied and calorie-sufficient diet to maintain energy levels for training and recovery.
It’s also vital for athletes to consume enough calories to maintain energy balance. Foods rich in fibre provide numerous health benefits but can also lead to early satiety (feeling full), which might make it challenging to meet high energy demands if not planned correctly.
Consulting Healthcare Professionals
Consultation with healthcare professionals, such as a doctor or dietitian, is advisable to tailor nutritional plans to individual needs. Healthcare providers can help identify and address potential nutrient deficiencies and develop strategies to optimise nutrient absorption.
For those new to the vegan lifestyle or those with specific health conditions, professional guidance can ensure that their dietary pattern supports their health objectives effectively.
