Pea protein isolate, derived from yellow split peas, is an increasingly prevalent additive and supplement in the food and beverage market, commonly found in alternative meats, meal replacements, cereal bars, alternative milks and additional food products. With pea protein isolate being relatively new to the market, there is not extensive research on its health benefits to coincide with its rising popularity. This review aims to cover the existing body of evidence to connect the known potential health benefits of pea protein isolate, as well as compare these health benefits to other protein alternatives that have been comprehensively researched such as soy and whey protein. The health benefits identified include its anabolic properties, high satiety effect, hypolipidemic effect and blood pressure lowering effect involving the renin-angiotensin-aldosterone system.
