High protein vegetables and grains

14 Aug 2023 • 20 min read

Protein is one of the most important macronutrients you need to consider when planning a healthy, nourishing diet. Not only does it help every cell in the body grow and repair itself, but evidence has also shown that protein is filling and encourages the body to improve muscle strength .

You don’t need to eat meat or fish to get enough protein either. There are several plant-based sources of this nutrient that supply the protein the body needs.

Here we’ve covered some of the best high protein vegetables and grains that you can include in your healthy high protein meals and recipes.

Skip to: What is plant protein? | Do vegetables have protein? | Are grains high in protein? | 5 high protein vegetables | 5 high protein grains.

What is plant protein?

As the name suggests, plant protein is protein that’s derived totally from plants. These sources can include legumes, grains, nuts, and seeds, as well as certain vegetables, and are an essential part of a plant-based diet as they provide the necessary amino acids needed for our bodies to build, recover, and grow.

While most animal sources of protein, like eggs, meat, or fish, are complete proteins (meaning they contain all the essential amino acids our bodies need), not many plant products contain much protein at all, let alone complete proteins.

This means that vegetarians and vegans may need to pay a little more attention to what they’re eating in order to hit their daily protein goals. But it doesn’t need to be stressful – a well-balanced plant-based diet that includes a variety of vegetables and grains can still provide all the essential amino acids your body needs.

Our ultimate guide to plant-based protein covers this in more depth.

Do vegetables have protein?

Do vegetables have protein?

Yes, vegetables do contain protein, although the exact content can vary a lot depending on the type of vegetable. Generally, legumes provide a higher amount of protein, but vegetables like spinach, broccoli, peas, potatoes, kale, and brussels sprouts can all help add towards your daily goals.

It’s important to note that while vegetables will contribute to your daily protein intake, they’re not complete protein sources, so they won’t contain all the essential amino acids your body needs. This is why it’s important to consume a varied diet with a range of plant-based protein sources like nuts, seeds, and grains (as well as meat alternatives like tofu, tempeh, or seitan). You can learn more about other vegetarian protein sources here.

Are grains high in protein?

Like vegetables, the protein content of grains can very among different types, and while they don’t contain as much protein as, say, legumes or nuts, they’re still an excellent way to increase your daily intake. Plus, they’re packed with a host of fantastic vitamins, energy-boosting carbohydrates, dietary fibre, and nutrients, making them a staple in any healthy diet.

By mixing grains with other high protein vegetables and ingredients, you can ensure a well-balanced nutritional approach that will keep your body happy and well.

5 High Protein Vegetables

Include these protein-rich vegetables in your diet and enjoy nutritious, delicious meals and snacks that are packed with goodness. Protein numbers listed here are a rough guide – they will likely differ between products, brands, and types of vegetable.

Lentils (100g contains 24g of protein)

Lentils (100g contains 24g of protein)

Lentils are a plant-protein holy grail – not only are they packed with protein, but they’re also a complete protein, containing all nine essential amino acids that the body can’t produce on its own – a rare thing in the plant world! Nutrient-rich, high in fibre, low in fat and easy to prepare, lentils are both affordable and versatile.

Unlike many other beans and pulses - which usually need soaking before they are safe to eat - lentils can be cooked and ready to eat. Use them to add texture to vegetable soups and stews, combine them with spices to make curries or eat them cold in salads.

As well as hummus, these legumes are used in a wide variety of Middle Eastern and Mediterranean recipes. Delicious when eaten hot or cold, chickpeas are a tasty addition to stews and curries or dry roasted in the oven to make a crunchy, protein-filled snack.
