How old are you biologically, and what are you doing about it?

In the latest Health Check podcast from The Straits Times, host Joyce Teo engages in a conversation with Dr Brian Kennedy, a distinguished professor of biochemistry and physiology at the Yong Loo Lin School of Medicine at the National University of Singapore. They delve into the burgeoning field of healthspan, which focuses on the period of life spent in good health, free from chronic disease, rather than simply extending lifespan.

Dr Kennedy discusses geroscience, the study of aging at a cellular level, and its potential to revolutionize healthcare from a proactive approach aimed at maintaining good health.

The discussion begins by exploring the concept of ageing clocks and geroscience, which are tools used to understand the biological processes that contribute to aging. Dr Kennedy highlights how these scientific advancements are shifting the paradigm from reactive sick care to proactive healthcare, enabling individuals to take more control over their health outcomes. He emphasizes the importance of maintaining an internal homeostasis for health and identifies when this equilibrium might break down.

Dr Kennedy shares insights from his transition from laboratory models to human trials conducted in Singapore, showcasing the country's growing influence in the field of longevity research. He also points out a comparative study that revealed Japanese individuals tend to be healthier in Japan compared to other countries where they have relocated. This suggests that environmental and cultural factors play a significant role in healthspan outcomes.

The conversation then touches on dietary factors, specifically whether a low carb, high protein diet could contribute to better aging. Dr Kennedy advises that while dietary choices are important, medical interventions remain crucial before one can consider longevity medicine. He stresses the necessity of addressing underlying medical conditions before focusing on longevity strategies.

Moreover, Dr Kennedy addresses the efficacy of hyperbaric oxygen chambers, a treatment method gaining attention for its potential to enhance healthspan. He delves into the complexities of choosing appropriate ageing supplements, underlining the need for personalized decisions based on individual health assessments and expert guidance.

Ultimately, Dr Kennedy advocates for empowering individuals to take charge of their own health decisions. He encourages a holistic approach that integrates medical advancements with personal health strategies, fostering a proactive mindset towards aging and well-being.
