What Vegetables Have the Most Protein


Most people think that building muscle is lifting weights and eating protein. Protein is an essential nutrient that your body requires to build and repair muscle tissue. And when you think of protein you immediately think of chicken, fish, pork, or steak.

The truth is that many other foods have a high percentage of proteins and you can incorporate them into your diet to reduce your dependency on animal-based protein. 

If you want to gain muscle and you are vegan or vegetarian, you are not hopeless. This article brings together a list of the top ten highly protein-packed vegetables that can help you build and tone your muscles, lose fat, and improve your overall health.

Keep in mind that proteins in veggies are not complete proteins, so you cannot depend entirely on one vegetable to build muscle. Try to integrate all of the following veggies into your diet to get full protein intake and start building muscle naturally while enjoying the many other benefits that they have.

Remember that it is recommended that you consume at least 5 servings of vegetables and legumes every day. Enjoy!


Key Takeaways

  • Consuming a high percentage of protein is essential to building and repairing muscle tissue, but it is not necessary to depend solely on animal-based protein.
  • Incorporating highly protein-packed vegetables into your diet can be an effective way to build and tone muscles while reducing the dependence on animal-based protein.
  • Ten highly protein-packed vegetables are lima beans, green peas, baked potatoes, spinach, broccoli, Brussels sprouts, mushrooms, corn, asparagus, and cauliflower. Each vegetable has varying amounts of protein and other nutrients.


Why Choose Vegetables-Based Protein?

Choosing vegetables as your primary protein source can positively transform your health and the planet. Leafy greens and other veggies are packed with fiber and vital nutrients while being low in saturated fats. This combination helps maintain a healthy weight, reduce cholesterol levels, and keep heart diseases at bay.

Beyond personal health, embracing plant-based proteins has substantial environmental benefits. Agriculture primarily centered around plant cultivation uses less land, water, and resources compared to animal farming. This results in fewer greenhouse gas emissions, less soil erosion, and minimal water pollution, contributing to a healthier planet.

Importantly, a diet rich in plant proteins doesn't mean sacrificing taste or variety. From lentils and beans to spinach and broccoli, there is an abundance of protein-rich vegetables to explore and enjoy. Therefore, opting for a plant-based diet is not merely a personal health choice but a move towards sustainable living.

The Versatility and Nutrient Density of Vegetables

Vegetables are a powerhouse of nutrients known for being highly versatile. Just think about it! Can any other food group match the sheer variety that vegetables offer in terms of colors, flavors, and textures? Probably not.

Take kale, for instance. This leafy green is brimming with protein and also boasts high levels of vitamin K and vitamin C. Spinach packs a punch in terms of protein per calorie and offers essential minerals like iron and calcium.

On the other hand, peas, often underestimated, are a solid source of protein. They're also rich in vitamins A, C, and B6.

Then there's broccoli, a vegetable that seamlessly fits into any dish and provides a good amount of protein. It's also a great source of fiber, potassium, and vitamin C.

These are just a few examples. The world of protein-rich vegetables is vast and exciting. It's all about understanding their nutrient profile and incorporating them creatively into your meals.

Remember, with vegetables, you're not just getting protein. You're also taking in a host of other essential nutrients. This makes them a superior choice for those seeking a healthy, balanced diet.

Complete Versus Incomplete Proteins in Vegetables

When it comes to proteins, it's essential to know about 'complete' and 'incomplete' proteins. The difference lies in the number of essential amino acids they provide. Complete proteins pack all nine essential amino acids our bodies can't produce. Common sources include meat, eggs, and dairy. But did you know some veggies can also offer complete proteins? Quinoa and soy, for instance, are two stand-out examples.

Don't frown upon vegetables for their incomplete proteins. While it's true they may lack one or more essential amino acids, it's not a drawback. Complementary proteins come into play here. 

Combine two or more plant foods, and voilà, you've got a meal with complete proteins. A classic example is rice and beans. It's an effortless way to ensure you're getting all the amino acids you need.

Eating a variety of vegetables is the key to a balanced, protein-rich diet. This variety ensures you acquire all the essential amino acids required for optimal health. So, broaden your veggie horizons! There's a whole world of healthy, tasty, protein-rich options out there.

Asparagus is a good source of vitamins A, C, E, K, and B6 and folate, iron, copper, and even protein. Each stalk of asparagus uniquely boosts your health.

The high level of B vitamins in asparagus can help regulate amino acids that can prevent heart disease. Also, it's a rich source of rutin, a compound that strengthens the walls of your blood vessels.

But what sets asparagus apart is its high fiber content. This helps to improve your digestion by flushing out toxins from the body. It also contributes to a feeling of fullness that can aid in weight management.

And let's not forget about its high content of antioxidants! These substances slow down the aging process and may even protect your body from chronic diseases.

Artichokes - 4.32 grams

Artichokes are not only delicious, but they also pack a protein punch of 4.32 grams per serving! This may come as a surprise, as many people tend to associate artichokes with being rich in healthy fats and fiber.

However, this vegetable is also loaded with antioxidants, vitamins C and K, calcium, magnesium, potassium, and folate. Artichokes are also a great source of iron, essential for producing and maintaining red blood cells.

In addition to its high protein content, artichokes are known for their cholesterol-lowering properties. They contain compounds that help reduce levels of LDL (bad) cholesterol while increasing HDL (good) cholesterol. This can help improve heart health and reduce the risk of heart disease.

Artichokes are also known for their ability to aid in digestion and promote a healthy gut. They contain prebiotic fibers that nourish the good bacteria in your gut, which is essential for maintaining overall health.

To get the most out of your artichokes, try steaming or grilling them and enjoy them as a side dish or in salads.

Broccoli, boasting 4 grams of protein per serving, cannot be overlooked for its protein content. Despite its small stature in the protein league, it holds its own with a slew of other health benefits.

First off, this green veggie is bursting with vitamin C - a single serving provides more than your daily requirement! This is crucial for the growth and repair of tissues in your body and an effective immune system booster.

But that's not all. Broccoli has a secret weapon: It's a potent source of dietary fiber. This aids in digestion and keeps your gut happy and healthy. It also helps you feel satisfied after a meal, making it a smart choice for those keeping an eye on their waistline.

Crowning its benefits, broccoli is a powerhouse of antioxidants like flavonoids and carotenoids. These nutrients combat harmful free radicals, reduce the risk of chronic diseases, and keep your body in tip-top shape.

The versatility of broccoli is another bonus. It can be enjoyed raw, steamed, grilled, stir-fried, and more - making it a versatile and nutritious addition to your meals.

Brussels sprouts - 4 grams

Brussels sprouts may not be the most popular vegetable, but they are a protein powerhouse. With 4 grams per serving, they pack quite a punch in terms of protein content.

But that's not all - these little green cabbages also contain vitamins K and C, as well as folate and fiber. Vitamin K is essential for blood clotting and bone health, while vitamin C plays a crucial role in the growth and repair of tissues. Folate, on the other hand, is necessary for proper cell function and development.

Additionally, Brussels sprouts are rich in antioxidants like kaempferol and quercetin, which have anti-inflammatory properties. They also provide glucosinolates, which are compounds that have been linked to cancer prevention.

The best way to cook Brussels sprouts is by roasting them in the oven with a little olive oil, salt, and pepper. This brings out their natural sweetness and creates a crispy texture that will have even the pickiest eaters reaching for seconds.

Mushrooms - 3.5 to 5 grams

Mushrooms are a favorite for vegetarians and vegans because of their meaty texture and umami flavor. But did you know that they also pack quite a bit of protein? Depending on the type, mushrooms can contain anywhere from 3.5 to 5 grams of protein per serving.

In addition to protein, mushrooms are rich in B vitamins, copper, potassium, and selenium. B vitamins help the body produce energy and are essential for the health of red blood cells, while copper is necessary for forming connective tissues and maintaining a healthy immune system. 

Potassium is an electrolyte that helps regulate fluid balance, nerve signals, and muscle contractions. Selenium is an antioxidant that plays a crucial role in thyroid function and DNA synthesis.

Mushrooms can be cooked in a variety of ways, from sautéing them with garlic and herbs to adding them to soups and stews. 

But for maximum protein content, you'll want to opt for lion’s mane and cordyceps. These varieties have the highest protein content compared to others. You can get them fresh or dried, or in one of the best on-the-go performance drinks in the market - TUNE IN.

  • Steaming: This method retains most nutrients within the vegetables. Consider steaming broccoli, peas, or spinach to preserve their protein content.
  • Grilling: Grilling adds a smoky flavor to vegetables and is great for vegetables like asparagus, bell peppers, and mushrooms.
  • Roasting: Roasting enhances the natural flavors of vegetables and is a great method for cooking Brussels sprouts, cauliflower, and potatoes.
  • Stir-frying: A quick stir-fry with a dash of healthy oil can be a great way to cook a mix of protein-rich vegetables. Consider a mix of bell peppers, broccoli, and mushrooms for a protein-packed meal.

Include Protein-rich Vegetables in Smoothies

Including protein-rich vegetables in smoothies is a tasty and simple way to increase your protein consumption. Leafy greens like spinach and kale are perfect for this, as they blend well and have high protein content. 

Adding a scoop of pea protein powder can further boost the protein level, providing essential amino acids.

Use Plant-based Protein Alternatives in Traditional Dishes

Substitute traditional ingredients with protein-rich vegetables or plant-based proteins in your favorite recipes. For example, replace meat with lentils in Bolognese sauce or use chickpeas in your curry instead of chicken. 

Such substitutions not only increase the protein content of your meals but also add a variety of textures and flavors.


Final Thoughts

Adopting a diet that includes high-protein vegetables is beneficial for health and offers a chance to get creative with your meals. Try crafting salads with a mix of edamame, lentils, and broccoli for a protein-packed lunch. For dinner, consider a hearty vegetable stew with peas, spinach, and kale. These combinations ensure you receive a complete protein source.

When shopping for these vegetables, look for those that are vibrant in color and firm to touch. Organic versions are a great choice to avoid pesticides. To store them, refrigerate in breathable produce bags to maintain freshness.

Storing fresh vegetables properly can help preserve their nutritional value and extend their shelf life. Keep them in the refrigerator's crisper drawer, which is specifically designed to maintain an optimal environment for fresh produce. Some veggies, like potatoes and onions, do better in a cool, dark pantry. Avoid washing them until just before use to prevent premature spoilage.

Incorporating protein-rich vegetables into your diet is a journey of exploration. Enjoy the process of discovering new flavors and textures. While it can be a change from traditional protein sources, it provides an opportunity to experiment with new recipes and contribute positively to your health and well-being.


Protein-Rich Vegetables: FAQs

How Can I Ensure I'm Getting a Complete Protein from Vegetables?

To ensure you're obtaining a complete protein from vegetables, it's vital to understand the concept of amino acid profiles. Proteins are made up of building blocks called amino acids, and there are 20 different types in total.

Nine of these are considered essential, meaning our bodies cannot produce them, and we must obtain them from our diet. Not all vegetables contain all nine essential amino acids in sufficient quantities, which is where the concept of 'complete' proteins comes from.

However, by 'combining' different vegetable sources of protein in your diet, you can ensure you ingest all the necessary amino acids. For instance, legumes might be low in the amino acid methionine but high in lysine, while grains might be high in methionine but low in lysine.

You can receive a full spectrum of essential amino acids by eating both in the same day. This idea of combining proteins is especially beneficial for vegetarians and vegans, who need to get their protein from plant sources.

Are These Vegetables Suitable for All Diets, like Keto or Paleo?

Yes, most protein-rich vegetables are suitable for various diets, including keto and paleo. However, the suitability largely depends on the specific carbohydrate content and the diet's guidelines.

For instance, the keto diet requires low carbohydrate intake, making vegetables like spinach, broccoli, and asparagus suitable options due to their high protein and low carb content. In contrast, starchy vegetables such as peas and corn, which are high in protein, may not be the best choice for the keto diet due to their higher carbohydrate content.

On the other hand, the paleo diet, which emphasizes whole foods, would welcome most high-protein vegetables. It's essential for individuals to understand their dietary restrictions and nutritional needs and choose vegetables that align well with those parameters.

How Do These Vegetables Compare to Traditional Protein Sources in Terms of Absorption?

When it comes to protein absorption, the bioavailability of protein from vegetables can vary compared to traditional sources like meat, eggs, or dairy. The term 'bioavailability' refers to the portion of the nutrient that is digested, absorbed, and metabolized through normal pathways. 

The biological value (BV) of protein, a measure of protein quality expressing the rate of efficacy at which dietary protein can be turned into body tissues, is typically higher in animal-based proteins.

However, this doesn't mean that vegetable proteins are inferior. Certain cooking methods, like soaking and sprouting legumes or combining diverse sources of plant proteins, can significantly improve the bioavailability of vegetable proteins.

It's crucial to remember that while the absolute protein content might be lower in vegetables, they are packed with other essential nutrients and dietary fiber, making them a vital part of a balanced diet. Vegetables are also generally lower in saturated fats and are cholesterol-free, offering additional health benefits beyond just their protein content.
