Episode 89: Protein and Skeletal Muscles: Keys to Longevity, Preventing Obesity, and Chronic Disease and Cancer
Description
Today, we will be learning why our muscular skeletal system may be out most important organ we have and how a Muscle-Centric Nutrition approach contributes to our to health and longevity and can preventing obesity, and other health issues such as cancer. We’ll be looking at the essential roles that protein and amino acids play, optimal dietary protein needs, ideal timing of protein intake, best sources, and everything we need to know about protein synthesis.
My guest is Don Layman, Professor of Food Science and Human Nutrition at one of the top agriculture colleges in the world, the University of Illinois Urbana-Champaign College of Agricultural.
Don earned his B.S. in Chemistry and M.S. in Biochemistry at Illinois State University and his Ph.D. in Human Nutrition and Biochemistry at the University of Minnesota, St. Paul.
His research focuses on understanding the protein and amino acid requirements and interrelationship between dietary protein and carbohydrates needed for adult health.
In particular, his research seeks to understand the impact of diet and exercise on obesity, type 2 diabetes, and metabolic syndrome in adults. His work has helped to define the role of branched chain amino acids (BCAA) in skeletal muscle metabolism.
BCAA provide an important energy source for muscle during exercise and also serve as a critical regulator of muscle protein synthesis during recovery.
During exercise, oxidation of BCAA increases, resulting in production of the amino acid alanine and a rapid decline in plasma levels of BCAA.
Amino acid supplements prevent this decline in plasma amino acids, enhance recovery of muscle protein synthesis and interact with insulin to help stabilize blood glucose.
His research continues to define mechanisms for control of muscle protein synthesis and differences in dietary protein needs for men versus women and for adults with sedentary versus active lifestyles.
He’s dedicated over 40 years investigating the intricate role of dietary protein in muscle protein synthesis and the impact of diet and exercise on obesity, type 2 diabetes, and metabolic syndrome in adults.
His research has significantly contributed to our understanding of the interplay between nutrition, muscle health, and overall well- being.
