Unlocking the power of pea protein: A plant-based superfood

Gaining popularity for its sustainability, and impressive health benefits, pea protein has emerged as a nutritional powerhouse. Pea protein is also known for its digestibility, and being a complete plant-based protein source that supports muscle growth, recovery, and overall well-being. To delve deeper into its nutritional profile, comparative benefits, and suggested daily intake, Edwina Raj, head of services, clinical nutrition and dietetics at Aster CMI hospital, Bangalore, and Samriddha Dasgupta Sarkar, clinical nutritionist consulting on Practo, answer the most frequently asked questions about pea protein.

What makes pea protein a ‘complete’ protein? 

Raj: Pea protein is often regarded as a complete protein due to its impressive profile of essential amino acids. It contains all nine of the essential amino acids that our bodies cannot produce on their own, making it a valuable source of nutrition, especially for those following plant-based diets. The quantities of these amino acids are particularly noteworthy; while it may not have the same levels of certain amino acids as animal proteins, it still provides a well-rounded balance that supports muscle growth, repair, and overall health. This makes pea protein an excellent choice for anyone looking to enhance their protein intake without relying on animal sources.

Why is pea protein considered to be a sustainable source of protein?

Sarkar: Pea protein is considered one of the most sustainable protein sources because its production requires fewer resources, including water and land, compared to animal-based proteins like meat and dairy. Peas naturally undergo a nitrogen-fixing process that replenishes nitrogen in the soil, thereby decreasing the need for synthetic fertilizers. This improves the health of the soil while lowering damage done to the environment.

The process of producing pea protein results in lesser greenhouse gas emissions and a smaller carbon footprint when compared to livestock farming, which itself is a huge contributor to global emissions. The infrastructures required for pea protein production are extremely low as compared to other protein sources; thus, it becomes an affordable source of protein and an environmentally friendly option to choose.

What are some creative ways to incorporate pea protein into a balanced diet?

Sarkar: Pea protein is a highly versatile ingredient that can be easily incorporated into various meals to enhance protein intake. Because of its neutral taste, pea protein works really well in both sweet and savoury recipes, making it such a budget-friendly and versatile addition to your day-to-day meals. There are many ways to use pea protein:

1. Mix into smoothies or shakes for post-workout recovery
2. Mix into pancake or waffle batter for a high-protein breakfast
3. Textured pea-protein chunks can be used in curries, stir-fries, soups, and pasta
4. Pea protein powder can also be made into homemade protein bars or energy balls for small snacks.
5. It can also be added to muffins, cakes, or bread for some added protein.

Is pea protein suitable for everyone?

Sarkar: Pea protein is generally well-tolerated and is considered among most safe protein sources. It is less allergenic than common protein sources such as dairy (whey) or soy, and it is an excellent alternative for people who have a soy allergy or are lactose intolerant.

Plant proteins like pea protein tend to be tolerated better by people who suffer from chronic kidney disease, as they are less stressful on the kidneys than animal protein. However, the increased risk for those patients with hyperuricemia (high uric acid levels) should be on the cautious side while ingesting pea protein because this could further increase the uric acid buildup in the body leading to a flare-up of gout. Also, people who have an allergy to specific legumes should consult a doctor before adding pea protein in their diet.

What are the different types of pea protein available?

Sarkar: There are different types of pea protein, mainly pea protein isolates, pea protein concentrates, and textured pea protein, each with distinct nutritional profiles and uses. Each type of pea protein serves different dietary needs, making it a flexible and valuable protein source.

1. Pea protein isolate is the most refined form, containing the highest protein concentration with minimal carbohydrates and fats. It is commonly used by athletes, bodybuilders, and vegans to support muscle protein synthesis and prevent muscle loss.
2. Pea protein concentrate, on the other hand, is less processed and retains some carbohydrates and fats, making it a balanced option for general dietary supplementation.
3. Textured pea protein comes in chunk or granule form and is often used as a plant-based meat substitute in burgers, stir-fries, and curries. It is a great option for children during their growth phase, as it provides essential nutrients in an appealing texture.

How does the protein content of pea protein compare to other plant-based protein sources like soy, rice, or hemp?

Raj: When evaluating the protein content of pea protein in relation to other plant-based sources such as soy, rice, and hemp, it becomes evident that pea protein stands out for its impressive amino acid profile and digestibility. While soy protein is often lauded for its complete amino acid content, pea protein offers a robust alternative that is not only rich in essential amino acids but also hypoallergenic, making it suitable for those with soy allergies. Compared to rice protein, which is lower in lysine, pea protein provides a more balanced amino acid profile, enhancing its appeal for those seeking a well-rounded plant-based protein source.

Beyond muscle growth and recovery, what other health benefits are associated with pea protein consumption? 

Raj: Incorporating pea protein into your diet can thus contribute to a holistic approach to health and wellness, making it a smart addition for anyone looking to enhance their overall well-being. Pea protein offers a multitude of health benefits that extend far beyond just muscle growth and recovery.

1. One significant advantage is its role in weight management; being high in protein and low in calories, it can help promote satiety, reducing overall calorie intake and aiding in weight loss efforts.
2. Pea protein is beneficial for heart health, as it can help lower cholesterol levels and improve overall cardiovascular function.
3. It plays a crucial role in blood sugar control, as its low glycaemic index helps stabilise blood sugar levels, making it an excellent choice for those looking to manage their diabetes or maintain steady energy levels throughout the day.

Is pea protein easily digestible?

Raj: Pea protein is often praised for its digestibility, but many wonder if it truly is easy on the stomach. While it is generally considered a gentle protein source, some individuals may experience digestive discomfort, including symptoms like gas or bloating, after consuming it. This can vary from person to person, depending on their unique digestive systems and dietary habits. Therefore, it`s essential to pay attention to how your body reacts when incorporating pea protein into your diet, as understanding your own digestive responses can help you make informed choices about your nutrition.

What is the recommended daily intake of pea protein, and how does that vary based on individual needs?

Raj: Understanding the optimal daily intake of pea protein is essential, as it can significantly differ based on individual requirements, such as those of athletes, vegans, and the general population. For athletes, who often have higher protein demands to support muscle recovery and growth, current intake needs to be assessed and additional requirement should be based decided which is up to 20 to 30 grams may be beneficial.

In contrast, vegans, who rely on plant-based sources for their protein, might aim for a similar range to ensure they meet their nutritional needs without animal products. Meanwhile, the general population typically requires less, with recommendations suggesting around 10 to 15 grams per day to maintain overall health. It is crucial to consider these varying needs to tailor protein intake effectively, ensuring that everyone can achieve their health and fitness goals while enjoying the benefits of this versatile plant-based protein source.
