Nutritional Composition and Functional Properties of Commonly Consumed Lentils: Impact of Commercial Lentil Types and Cooking Processes
Cross-Sectional Study2026
The study looked at different lentils and found they contain about 25–30% protein, which is a high amount for a plant food. Red lentils are one of the lentils studied, so this supports that red lentils are high in protein.

Contradicting (1)

Weak

Determination of the protein quality of cooked Canadian pulses
Cohort StudyAnimal2017
The study checked whether cooked red lentils qualify as a high-protein food under official rules. It found they do not meet the cutoff for a protein source claim, so the claim that red lentils are high in protein is not supported.

Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.

Scores reflect study quality, not just count.
