Are you getting enough essential amino acids? Dr. David Church joins me to compare amino acid profiles and their impact on health. When we look at the math behind protein quality, the differences between animal and plant sources are significant. In a trial he helped design, Dr. David Church matched a 4-ounce beef patty against a soy-based burger. He had to double the soy to roughly match the single beef patty in essential amino acids. The blood amino acid levels shocked him.
