Pea Protein for Weight Control

How Much Is Usually Taken by Dieters?

People who use a high-protein diet for weight loss typically aim to get 25–30% of their daily calories from protein; in other words, a 1,500 to 1,800 calorie per day diet would include 95 to 135 grams of protein. Most people who use pea protein to reach this goal use one or two 30-gram servings, with each serving providing as much as 25 grams of protein.

Side Effects

People with peanut, soybean, or other legume allergies should be careful when adding pea protein to the diet. Even though peas are not a major cause of allergies, pea allergies are more common in people who have other legume allergies.1

Carbohydrate molecules called oligosaccharides may be present in varying amounts in pea protein extracts. These molecules can cause intestinal discomfort and gas in some people. A processing technique called ultrafiltration reduces the amount of oligosaccharides remaining in pea protein and reduces this side effect.2

Interactions with Supplements, Foods, & Other Compounds

Pea protein extracts have varying amounts of phytic acid, a plant chemical found especially in legumes that interferes with the absorption of minerals including iron. One study found that babies given a pea-based formula absorbed iron better when the formula was fortified with vitamin C.3 Processing techniques like dialysis, ultrafiltration, hydrolysis, and enzymatic treatment can reduce the amount of phytic acid remaining in protein extracts from legumes.4, 5, 6
