Plant-based protein is found in foods such as legumes, soy, nuts, seeds, and whole grains. These sources provide essential amino acids, help maintain muscle mass, and are part of a balanced diet at any stage of life. Including plant-based protein and foods rich in this macronutrient is key to optimizing cardiovascular and digestive health.
In short
What you will learn in this article
There is no single "best" plant-based protein. The secret to optimal nutrition lies in combining different sources throughout the day.
Foods like soy, quinoa, or chickpeas provide all the essential amino acids that the body needs.
In addition to contributing to tissues, these proteins provide fiber and phytosterols related to cardiovascular and digestive health.
What is plant protein
Proteins are essential macromolecules composed of chains of amino acids that the body uses to repair tissues, regulate hormones, transport oxygen in the blood, and maintain the immune system in optimal condition.
When we talk specifically about plant protein, we are referring to those amino acids that we obtain directly from the plant kingdom (such as legumes, seeds, nuts and cereals) instead of from livestock or marine sources.
Differences between plant protein and animal protein
The main difference between animal and plant-based protein lies in their amino acid structure and their nutritional support.
While animal sources typically contain all the essential amino acids directly, they also provide saturated fats. Plant-based proteins, on the other hand, come with fiber, antioxidants, and zero cholesterol, making them excellent allies for health.
What are the foods richest in plant protein?
Legumes
They are the foundation of plant-based nutrition. Lentils, chickpeas , and beans stand out not only for their protein content but also for their high iron and fiber levels. They are incredibly versatile and filling.
Soybeans and derivatives
Soybeans are the queen of plant-based protein sources. Their derivatives, such as tofu (soy cheese ideal for absorbing flavors), tempeh (fermented soybeans rich in probiotics), and edamame (green soybeans in pods), offer protein densities identical to or higher than those of many meats.
Dried fruit
Almonds , pistachios , and peanuts (which are technically legumes but are eaten as nuts) are perfect for enriching dishes or snacking between meals. They provide an excellent dose of protein and healthy fats.
Seeds
Chia , hemp , sesame , and pumpkin seeds are nutritional powerhouses. Hemp seeds, in particular, are notable for their high protein content, while chia seeds provide Omega-3 fatty acids.
Whole grains
Oats , quinoa , and buckwheat challenge the notion that grains only provide carbohydrates. They are essential for structuring main dishes and ensuring a sustained energy supply.
The following details the plant-based protein foods with the highest nutritional density per 100 grams of dry or raw product:
| Food | Protein per 100g | Key benefit |
|---|---|---|
| Soybeans (dried beans) | 36 g | It contains all the essential amino acids. |
| Peanuts | 26 g | Rich in monounsaturated fats and vitamin E. |
| Lentils | 24 g | Excellent source of iron and soluble fiber. |
| Chickpeas | 19 g | Very versatile, ideal for hummus and stews. |
| Tempeh | 19 g | Fermented food beneficial for the microbiota. |
| Almonds | 21 g | High in calcium and antioxidants. |
| Quinoa | 14 g | Pseudograin cereal with high quality protein. |
What is the best plant-based protein?
There is no single best plant protein; the best option is a biological combination of several of them.
Soybeans: the most complete plant protein
Due to its biological value and digestibility, soy is considered the best single plant protein. Its amino acid profile is as complete as that of meat or eggs. In specialized establishments, such as the culinary offerings at Restaurants Artemisa, soy and tofu are transformed into gourmet dishes that demonstrate that healthy eating is a culinary pleasure.
Quinoa and amaranth
These pseudocereals are at the top because they naturally contain all 9 essential amino acids that the human body cannot produce on its own, without any additives.
Legumes combined with cereals
Folk wisdom already did this intuitively: lentils with rice. By combining a legume (limited in the amino acid methionine) with a cereal (limited in lysine), a protein with a biological value comparable to that of a beef steak is obtained.
Plant-based proteins for athletes
For people with high physical exertion, pea and rice protein isolates complement each other perfectly in post-workout shakes, ensuring rapid cellular absorption without causing the stomach heaviness of dairy products.
Complete and incomplete plant-based proteins
To design a balanced menu, it is vital to understand how the structures of the proteins we consume work.
What are essential amino acids?
Amino acids are the building blocks of proteins. There are nine essential amino acids that our bodies cannot synthesize on their own and that we must obtain through food.
Foods with complete protein
These are foods that contain all nine essential amino acids in optimal proportions. Examples include soybeans, quinoa, chickpeas, pistachios, and hemp seeds.
How to supplement plant-based proteins
If a food contains an "incomplete" protein, it doesn't mean it's useless. You just need to supplement it throughout the day. You don't have to do this in the same meal; simply consuming whole grains, nuts, and legumes within a 24-hour period is enough for your body to create its own complete proteins.

Plant-based diet
Benefits of consuming plant protein
Increasing the presence of plant-based protein sources can provide additional nutritional benefits thanks to their fiber content, healthy fats, and other compounds present in plant-based foods.
Cardiovascular health
Plant-based sources help reduce the presence of saturated fats within a balanced diet.
Cholesterol control
Phytosterols, present in many plant foods, help maintain healthy cholesterol levels.
Higher fiber content
Fiber helps regulate blood sugar and helps prolong the feeling of fullness.
Digestive health
It promotes intestinal transit and contributes to the balance of the digestive microbiota.
Maintaining muscle mass
Plant proteins provide amino acids necessary for tissue recovery and maintenance.
How much plant-based protein is recommended to be consumed per day?
Protein requirements vary according to the lifestyle, weight, and age of each individual.
Recommendations for adults
As a general rule, the WHO recommends a minimum intake of 0.8 grams of protein per kilogram of body weight per day. For a 70 kg person, this equates to about 56 grams of protein daily.
Needs in older people
As we age, our bodies process protein less efficiently. Therefore, older adults need to increase their protein intake to 1.2–1.5 grams per kilogram of body weight per day to prevent bone and muscle loss.
Requirements for active individuals
Athletes or people who do strength training require between 1.6 and 2.2 grams per kilo, levels that can be perfectly met by increasing the portions of legumes, tofu, seeds and clean plant supplements.
How to include it in your daily diet
Making the transition to or increasing your plant-based diet is easier and more delicious than it seems.
Breakfasts rich in plant-based protein
Swap buttered toast for whole-wheat toast with hummus or avocado and hemp seeds. Another fantastic option is a bowl of cooked oatmeal with soy milk, walnuts, and chia seeds.
Main meals
Make legumes the main course, not a side dish. A great option for your weekdays is to enjoy balanced meals out; you can check out the healthy options on thedaily menu at Artemisa on Gran Vía or thedaily menu in Huertas, where you'll always find homemade dishes designed to provide clean, nutritious energy.
Healthy snacks
A handful of unsalted roasted almonds or pistachios, carrot sticks with peanut butter, or boiled edamame with a touch of paprika are perfect alternatives for snacking between meals.
Simple substitutions for animal protein
Replace the minced meat in pasta or lasagna with textured soy protein.
Replace the chicken in your salads or stir-fries with cubes of marinated firm tofu.
Use white beans to add creaminess to your soups instead of heavy cream.
Common mistakes when following a diet rich in plant protein
Consume few calories: Because they are high in fiber, plant-based foods are filling. It's important to ensure you consume enough energy so your body doesn't use its own protein as fuel.
Don't vary your protein sources: Eating only salad or relying exclusively on chickpeas will limit your nutrient intake. The key is rotation: include mushrooms, grains, seeds, and different types of legumes.
Neglecting vitamin B12: Vitamin B12 is the only nutrient that is not readily available in plant-based foods. If you follow a 100% vegetarian or vegan diet, supplementation under professional supervision is mandatory, regardless of your protein intake.
Thinking that all plant-based protein is the same: Ultra-processed vegan foods (like certain industrial burgers loaded with sodium, refined oils, and starches) are not the same as eating healthy. Always prioritize real food and whole ingredients.
Myths about plant protein
It's time to break down the historical prejudices surrounding plant-based cooking.
Is plant-based protein less nutritious?
False. It provides the same calories per gram (4 kcal) as animal protein and, due to its fiber and micronutrient content, nourishes cells more cleanly, leaving fewer metabolic waste products in the body.
Is it insufficient to gain muscle?
False. Many world-class athletes base their performance on plant-based protein. The crucial factor is meeting the total daily requirement for amino acids and maintaining the appropriate training stimulus.
Is it only suitable for vegetarians?
False. Anyone who wants to take care of their arterial health, reduce their ecological footprint, or improve their digestion benefits greatly from replacing some meat meals with plant-based alternatives throughout the week.
