Pea Protein and the Paleo Diet

Diet & Nutrition Inspiring People

AUTHOR: Cliff Harvey, PhD (Clinical Nutritionist & Researcher)

The idea behind the Paleo diet is that we haven’t really changed much since the time of the earliest humans and it has been said that: “From a genetic standpoint, humans living today are Stone Age hunter-gatherers displaced through time to a world that differs from that for which our genetic constitution was selected.”1 If you follow a paleo diet, you probably have a lot of questions about what you should eat. Continue reading if you are curious about consuing pea protein on a paleo diet.

Hunter-gatherer peoples like the Inuit, Australian Aboriginals, Hadza, and others have until very recently lived in robust health and only with the introduction of modern, highly refined foods have begun to experience high rates of the metabolic disorders of obesity and diabetes that plague the modern western world.2-5

What’s the Paleo Diet?

The modern Paleo diet seeks to emulate these hunter-gatherer diets by eliminating the processed and refined foods that are abundant in the modern diet. And while the diet has received some criticism, research shows many benefits from following Paleo, including improved satiety when compared to standard dietary guidelines,6-8 reduced cholesterol, triglycerides (fats in the blood) and other markers of heart disease,9,10 along with improved fat-loss and muscle retention.11,12

Can I have Pea Protein on a Paleo Diet?

Legumes (like peas, lentils, chickpeas, and mung beans) are typically avoided on a Paleo-style diet because they contain various anti-nutrients such as phytic acid that can inhibit the absorption of minerals, and trypsin inhibitors and other compounds that can impair protein digestion. Overall though, these aren’t actually an issue for most people. Not to mention that phytic acid and many of the other anti-nutrients are also reduced markedly during most types of food preparation, including cooking, soaking and sprouting. Nowadays, high-quality pea protein isolates are processed using a low-heat, enzymatic isolation process (which is functionally very similar to fermenting or sprouting) and this effectively removes almost all the phytate, lectins, saponins, and trypsin inhibitors. As you can see in the table below pea protein isolate contains practically no anti-nutrients.

So, despite it being derived from a legume, pea protein isolate has become a favorite of many in the Paleo community, especially many CrossFit athletes who were early adopters of Clean Lean Protein because it provides a convenient, extremely high-protein, and very low-carb protein option that is also free from other common allergens like gluten, dairy proteins, and soy.

So, while it’s not technically Paleo, pea protein isolate is Paleo-friendly because it offers a low-allergen, easy to digest, high protein option that is practically free-from anti-nutrients. Many people follow modified Paleo-style approaches to diet and find that pea protein isolate helps them to get in the protein that they need when they need it.
