Pea protein (Pisum sativum)
Synopsis of pea protein
Pea protein is a high-quality, plant-based protein extracted primarily from yellow split peas (Pisum sativum), commonly used in vegan and hypoallergenic nutrition. It is especially rich in branched-chain amino acids (BCAAs) like leucine, isoleucine, and valine, and contains high levels of lysine, which is often low in other plant proteins. Although it is not a complete protein on its own (it is relatively low in methionine), it is highly digestible and well-tolerated, making it ideal for a wide range of health applications.
Pea protein is used medicinally to support muscle maintenance and growth, post-exercise recovery, and metabolic health. Its hypoallergenic profile (free from dairy, soy, gluten, and eggs) makes it a preferred choice for individuals with food sensitivities or digestive issues. It also has a low glycemic index and promotes satiety, making it beneficial for weight management and blood sugar control.
Emerging research suggests pea protein may help lower blood pressure, improve kidney function, and support cardiovascular health. It is also included in medical nutrition formulas for people recovering from illness, surgery, or those with malabsorption issues. Due to its high iron content, it is often recommended for vegans and vegetarians at risk of anemia.
Pea protein powders are often fermented or enzyme-treated to improve digestibility and reduce natural anti-nutrients like phytic acid and lectins.
Historical Use in Medicine
While pea protein isolate is a modern innovation, peas themselves have a long history in traditional diets and medicine. In Ayurveda, peas were considered nourishing and grounding, used in simple dishes to support digestion, blood sugar regulation, and muscle health.
In Traditional Chinese Medicine, peas were believed to clear heat, reduce inflammation, and support intestinal function. Peas were often included in congee and healing broths to restore vitality and strength.
In European folk medicine, peas were seen as food for the poor and sick, but valued for their ability to restore energy and tissue after illness. They were included in recovery diets and spring cleansing routines due to their mild diuretic effect and nutrient density.
The extraction of pea protein as a concentrated supplement began in earnest in the late 20th century, spurred by growing interest in vegan and allergen-free protein sources. It quickly became a cornerstone of sports nutrition, weight loss protocols, and functional foods, especially as awareness of lactose intolerance, soy sensitivity, and sustainability increased.
