Beef Protein vs. Plant Protein: A Complete Nutritional Comparison

Abstract Summary

Objective: To systematically review and analyze the effects of animal versus plant protein intake on lean mass and muscle strength in adults.

Context: With increasing interest in plant-based diets, it's important to understand how plant proteins compare to animal proteins in supporting muscle health, particularly concerning lean mass and strength.

Methods Used

Approach: A systematic review and meta-analysis of randomized controlled trials comparing the effects of animal and plant protein on muscle outcomes.

Data Collection: Data from multiple studies were aggregated to assess changes in lean mass and muscle strength associated with different protein sources.

Researchers' Summary of Findings

The analysis indicated that while both protein sources support muscle health, animal proteins have a slight advantage in promoting lean mass gain, especially in younger adults. However, no significant differences were observed in muscle strength outcomes between the two protein sources.
