3Sources of plant-based proteins
“My favourite plant-based complete proteins would be quinoa, soy products, hemp seeds and chia seeds.” says Emily…
Plant-based diets have been popular for a long time now, with many people choosing to reduce or eliminate meat entirely for health, ethical or environmental reasons.
Recent research has shown that a whole-foods, plant-based diet can provide all the protein you need and improve your health and longevity.1-5
“Protein is really important for football players and vegetarians and vegans still have the same protein goals than those who eat animal-based foods,” begins Emily Foster, an in-house nutritionist at H&B.
In our complete guide to plant-based protein, we’ll explore how much you need and how to get it from a plant-based diet. We’ll also reveal the best sources of plant protein and our top four picks for plant-based protein powders.
What is plant-based protein?
Alongside carbohydrates and fat, protein is one of three essential macronutrients for our health. Protein has many functions, including promoting cell and tissue growth, helping to maintain and build healthy muscles and bones and supporting our immune systems.6
“A few of my favourite proteins are called “complete proteins”, which contain all essential amino acids. We have ones which the body can produce themselves. But then we have ones which we have to consume from diet and to be able to promote muscle repair, recovery and growth,” says Emily.
“Some foods will contain all essential amino acids, whereas other foods you'll have to pair with foods that contain different types of essential amino acids to be able to achieve a complete protein.”
You probably already know that dietary protein can be found in both animal and plant-based sources.7 But is there any difference in the quality of animal and plant-based protein? Let's find out.
Animal protein vs plant-based protein
The key difference between animal protein sources, like meat, fish, eggs and dairy, versus plant-based sources, such as beans, lentils, nuts, seeds and whole grains, comes down to their amino acid profile.1,2
Proteins are made up of 20 amino acids – nine of which are essential, because our body can’t make them.1,2,8
Some plant-based proteins do not contain as many essential amino acids1,2,8 However, there’s a simple way to overcome this when following a plant-based diet. By eating a wide variety of different plant-based proteins throughout the day, you can ensure that you get adequate amounts of all nine essential amino acids.1,9
Furthermore, some studies have found that plant-based protein sources are typically lower in saturated fat, sodium and cholesterol than animal sources, meaning that cutting meat out of your diet may contribute to weight loss and better cardiovascular health.3,4,7,11,12
How much protein do you need?
The average healthy adult needs around 0.8–1g of protein per kg of body weight per day.13
However, a number of things may increase your protein needs, such as your activity level and health – strength and endurance athletes are advised to consume more protein (around 1.2-2.0g of protein) as do people who are unwell or recovering from an operation (closer to 1.5g per kg).13,14,15
You may also want to consume more than the recommended amount of protein for several reasons:
- protein helps build and repair muscles, so you should increase your daily protein intake if you want to improve your athletic performance and strength (while still having enough carbs and fibre)16,17
- a high-protein meal or snack can leave you feeling fuller for longer, which may mean you’re more likely to opt for healthier choices when snacking and prevent you from over-snacking18,19
- a high-protein diet may help you lose weight and improve your body composition in combination with a balanced diet18,20
Sources of plant-based proteins
If you follow a plant-based diet, there’s a wide variety of plant-based foods that are rich in protein for you to choose from.21
“My favourite plant-based complete proteins would be quinoa, soy products, hemp seeds and chia seeds.” says Emily.
“For combinations, rice and beans are a good pairing. Rice is really low in an essential amino acid called lysine, but it's high in methionine, whereas beans are the opposite. So if you consume your rice and your beans together you create a complete protein.”
Soy products are high-quality protein sources made from soya beans. They’re thought to contain all nine essential amino acids, meaning they’re a source of complete protein.22
Products made from soy include:23,24
- tofu
- tempeh
- edamame
- soya milk
- textured vegetable protein
Pulses are the dried seeds of legumes. They’re a nutrient-dense food high in protein, fibre, vitamins and minerals.25
Pulses are an inexpensive and healthy way to incorporate more protein into your diet.
Examples include:25
- white beans
- black beans
- kidney beans
- chickpeas
- lentils
- peas
Nuts and seeds are another great way to boost your protein intake. These calorie and nutrient-dense foods provide a good serving of protein, healthy fat and fibre.26
Some of the best choices of nuts and seeds include:26
- hemp seeds
- pumpkin seeds
- peanuts
- almonds
- cashew nuts
- chia seeds
- walnuts
- hazelnuts
Most people think of whole grains as an important source of carbohydrates, but they’re also a source of dietary fibre and can provide a moderate amount of protein.27
The following whole-grain foods include a good serving of protein:28
- oats
- buckwheat
- quinoa
- millet
- whole-grain bread
- brown rice
You may be surprised to find out that you can also find plant-based protein in some vegetables.21
Another excellent protein source is seitan, which is made from wheat gluten.29 Seitan is a complete protein that can be used as a meat replacement, but you should avoid it if you have coeliac disease or a sensitivity to gluten.30,31
Other notable sources of protein can include:
- nutritional yeast33
- mycoprotein (Quorn)34
- spirulina35
Our favourite plant-based protein powders
Eating a varied and abundant diet is the best way to hit your protein goal. But if you want to increase your daily protein, a plant-based protein supplement can boost your overall daily protein intake.36
Here are our top picks for plant-based protein supplements.
