Episode 98: Lee Hamilton, PhD, of the University of Stirling is on the show to discuss the impact of omega 3 fatty acids on muscle function & metabolic health via inflammation & insulin sensitivity.
Guest Bio
Lee Hamiton, PhD.
Lee Hamilton PhD. is a sports physiology researcher based at the University of Stirling.
Dr. Hamilton’s primary research goal is to understand the molecular basis of skeletal muscle plasticity (the ability to change depending upon environment). Muscle is a very plastic tissue with the ability to grow with extra loading and become more fatigue resistant with training. However, muscle will also waste with inactivity and loose metabolic flexibility with poor nutrition.
He is also interested in developing nutritional interventions to assist in maintaining glucose homeostasis in patients with Type 1 Diabetes.
In this episode we discuss:
- Why the metabolic function of muscle is so important
- Data on omega 3 fatty acids and muscle function
- Possible mechanisms of action: inflammation, insulin sensitivity, etc.
- Ratio of omega 6 to omega 3 in the diet: Is there such thing as optimal?
- Implications for high-fat diets
- Marine sources vs. plant sources (EPA + DHA vs. ALA)
- Incorporation of fatty acids into cell membrane
- Practical effects on muscle hypertrophy
