On this episode of humanOS Radio, I speak with Lynda Frassetto. Lynda is a Professor Emeritus of Medicine in the Division of Nephrology at UCSF. During her research career, she and her colleagues investigated regulation of acid-base balance in both healthy and older people, as well as dietary influences on acid-base balance.  In particular, she has explored how the ratios of potassium to sodium, as well as base to chloride, differ...

Brad has a PhD in Exercise Physiology from the University of Idaho, and did further training in biomedical research examining how metabolism and inflammation regulate molecular mechanisms of disease. He is a scientist, a coach, an entrepreneur, a writer, and a speaker, so he wears a lot of different hats. Brad has been leading research behind transdermal delivery of ca...

Within our gut resides a vast ecosystem that guides countless facets of health and performance. Emerging research shows that your gut microbiota may impact many different and seemingly unrelated aspects of health and bodily function, including appetite and body weight regulation, lifespan, mood, cognition, and even athletic performance. We also know that the gut plays a role in the immune system. In fact, it is thought that over 7...

Jennifer has a Ph.D. in Clinical Psychology from the University of Michigan, and is currently faculty at the University of Pennsylvania. Her research explores how altering aspects of sleep can produce changes in mood and emotional regulation, particularly in those with major depression. Jennifer’s work has led her to investigate a long-recognized but poorly u...

The market for dietary supplements to enhance sports performance has exploded in recent years. In fact, you may have tried some of these supplements yourself to improve your workouts. Many common supplements, like caffeine, have been studied in the context of immediate performance enhancement, and are used with that goal in mind. But the effect of chronic supplementation, particularly in endurance training, is not as well underst...

When you hear the word superfood, what do you think of? Probably kale. Goji berries. Green tea. Turmeric. Countless others. But what about mushrooms? Mushrooms have historically not held a prominent place among the list of superfoods. But if you take a closer look, I think you’ll find that the humble mushroom actually has a lot going for it. A single cup of whole white mushrooms - like the kind you usually see at grocery stores...

On the surface, sleep looks like a colossal waste of time. Think about it. We spend about a third of our lives lying down with our eyes closed...basically doing nothing! It’s easy to see why high-achieving people throughout history - like Thomas Edison and Benjamin Franklin - aspired to get by with less of it. Even today, people who are trying to maximize productivity are prone to shortchanging sleep so they can get more done. Tw...

For much of our history as a species, the threat of chronic food shortage and malnutrition has loomed over us. Fortunately, due to global economies and remarkable advances in technology and agriculture, most of us living today in industrialized countries will probably never need to worry about starvation. But ironically, we now must battle the consequences of excessive abundance of readily accessible food. All over the world, m...

Have you ever wondered what your great-great-grandparents would think of the world today - and how we live - if they were transported here via a time machine? Our lives have changed drastically in too many different ways to recount here (and most of these changes are, arguably, pretty great to be honest). But for those of us who study health and human biology, our patterns of physical activity is perhaps among the most glaring. Su...

Why do so many people struggle to stick to a healthy lifestyle? Health-related goals are largely the product of long term modifications to how we live. And we generally don’t see an immediate payoff from these individual choices, at least not in the moment. To paraphrase James Clear, it is only after your efforts have compounded over time that you start to see the payoff of these behaviors, for better or for worse. But therein ...

All of us have heard the aphorism, “Let food be thy medicine, and medicine be thy food.” This maxim, of course, is usually attributed to ancient Greek physician Hippocrates. However, if you’ve ever spent time looking at health-related content on Twitter and Instagram, you’ll realize that conflating diet and medicine is a modern phenomenon. We like to think of certain foods and combinations of foods as exerting drug-like effects. ...

On this episode of humanOS Radio, Dan welcomes Aly Orady - founder and CEO of Tonal - to the show. Aly’s story is an all too common example of the price of success in the modern world. Aly was excelling professionally, but in the process his health was falling apart. He was overweight, and had developed type 2 diabetes and sleep apnea. And he was only in his mid-thirties. He was moving on a dangerous path, and he knew it. Real...

Light is essential to life as we know it. Plants rely upon sunlight to generate chemical energy, which is stored in their tissues and fuels various life processes. In turn, animals like us convert the energy from the food that we eat into mechanical energy. Given its fundamental role in our biology, perhaps it makes sense that specific types of light are connected to our health in some surprising ways, which research is only just...

Insomnia is a uniquely vexing medical problem. It is the most common sleep-related issue, thought to affect around 10-40% of the population in the US. So it is a challenge that affects a whole lot of us. Yet despite its prevalence, treatments for the condition are lackluster at best. Why is this the case? Perhaps because it remains poorly understood. Insomnia has been known and documented for thousands of years, but it has proven ...

On this episode of humanOS Radio, Dan welcomes Nicola Bondonno to the show. Her research has been examining the effects of bioactive compounds occurring naturally in plant-based foods and beverages, and how they are linked to the cardiovascular health benefits associated with a plant-rich diet. It has become axiomatic that fruits and vegetables are protective against disease. Humans have intuitively recognized the link between edi...
