Explore the vegan protein guide: Discover various sources of protein in a plant-based diet
Vegan diets, often associated with a lack of protein, can be a source of complete proteins that meet the needs of a healthy individual. While animal proteins like meat, eggs, and dairy are naturally complete proteins, containing all nine essential amino acids in ideal proportions for human needs, some plant-based foods can also provide a complete amino acid profile.
Protein-Rich Plant-Based Foods
Spirulina, a blue-green algae, stands out as a highly protein-rich food, containing 57.5g of protein per 100g. Hemp seeds, on the other hand, offer 9.47g of protein per three tablespoons. Hummus, a popular dip, contains 3.3g of protein per 100g, while boiled chickpeas offer 14.5g of protein per cup.
Other plant-based foods that are naturally complete proteins include soy, quinoa, buckwheat, chia seeds, and amaranth. Lentils, broccoli, peanuts, oats, and mushrooms, when prepared correctly, can also contribute significantly to daily protein intake.
Preparation and Bioavailability
While plant proteins can be a valuable source of essential amino acids, their digestibility and bioavailability may be slightly lower due to fiber and antinutrients like phytates. However, traditional preparation methods like soaking, sprouting, fermenting, and cooking can greatly improve digestibility and nutrient availability.
Vegan Protein Supplements
Some vegan protein powders, like PlantFusion, are formulated to compensate for common limiting amino acids in plant sources by including methionine-rich ingredients like algae and amaranth, ensuring a balanced and complete spectrum of essential amino acids comparable to animal proteins.
Balancing a Vegan Diet
While vegan sources can provide complete essential amino acid profiles comparable to non-vegan sources when well-selected or combined, it's essential to be mindful of protein intake. Excessive protein intake can lead to health problems such as intestinal discomfort, liver and kidney failure, and increased risk of cardiovascular disease.
Pregnant individuals should increase their daily protein intake by 10%. The RDA of protein for different age and sex groups is provided in the table below.
| Food | Protein per 100g | |------------------------------|---------------------| | Spirulina | 57.5g | | Hemp seeds | 9.47g | | Hummus | 3.3g | | Boiled Chickpeas | 14.5g | | Lentils (boiled) | 8.95g | | Broccoli (cooked in oil) | 4.54g | | Raw Oats | 10.7g | | Peanuts | 7.31g | | Almond Butter | 20.96g | | Mycoprotein | 11g | | Mushrooms (cooked with oil) | 5.98g | | Fried Tofu | 5.34g | | Quinoa (cooked) | 7.45g | | Soybeans (raw) | 16.6g | | Soybeans (cooked) | 15.65g | | Peanut Butter | 7.2g | | Tempeh (cooked) | 15.2g |
In summary, vegan sources can provide complete essential amino acid profiles comparable to non-vegan sources when well-selected or combined. Advances in vegan protein formulations continue to close any gaps in amino acid composition and absorption. It's crucial for vegans to be mindful of their protein intake and possibly supplement when necessary to ensure all essential amino acids in sufficient amounts.

- Spirulina, a high protein-rich plant-based food, contains 57.5g of protein per 100g.
- The predictive health benefits of vegan diets can be influenced by proper planning and preparation, as plant proteins might have slightly lower digestibility due to fiber and antinutrients like phytates.
- Certain plant-based foods, such as lentils, broccoli, peanuts, and mushrooms, can contribute significantly to daily protein intake when prepared correctly.
- Aq, like algae in PlantFusion vegan protein supplements, can be instrumental in ensuring a balanced and complete spectrum of essential amino acids in plant-based diets.
- By following a healthy-diets approach that includes nutrition from sources like protein-rich plant-based foods and possibly protein supplements, vegans can maintain optimal health and wellness, minimizing the risk of health issues such as depression, obesity, and psoriasis.
