  • The workout that builds muscle, boosts your brain and slows down aging | Dr. Andy Galpin

    The workout that builds muscle, boosts your brain and slows down aging | Dr. Andy Galpin
    Apr 3 2025
    Strength training is often associated with bodybuilding, but its benefits go far beyond muscle growth. Research shows that strength training supports cardiovascular health, enhances brain function, and is a strong predictor of longevity. In this episode, Professor Andy Galpin joins us to break down the science behind strength training and show how anyone can incorporate it into their daily routine—without spending hours in the gym. We begin by exploring why strength matters, not just for physical appearance but for overall health and longevity. Andy revisits key insights from his last appearance on the podcast, demonstrating how grip strength is linked to life expectancy. Next, we tackle one of the biggest barriers to strength training: time and access. Jonathan steps in as the test subject while Andy walks him through an efficient, full-body workout that can be done at home with minimal equipment. Listeners will learn essential techniques, from proper form to breathing and injury prevention. Finally, we discuss what happens in the body post-workout and the importance of building a sustainable routine. Andy shares practical advice on nutrition, recovery, and how to create a strength training habit that delivers long-term results. 🥑 Make smarter food choices.

    Recap: Is friendship the key to healthy aging? | Rose Anne Kenny
    Apr 1 2025
    Last year, a study found that a third of Americans aged between 50 and 80 feel lonely. I’m sure most of us can relate to this feeling, and understand how a lack of social connection can take a serious toll on our mental health. But, is loneliness affecting more than just our minds? Does it also impact our physical health and how well we age? In this episode, Professor Rose Anne Kenny joined me to answer these questions and discover ways that we can foster meaningful relationships. She starts by telling us about her groundbreaking study into ageing in Ireland. 🥑 Make smarter food choices.

  • The truth about low carb diets, sugar spikes, and ‘multigrain’ labels | Prof. Tim Spector

    The truth about low carb diets, sugar spikes, and ‘multigrain’ labels | Prof. Tim Spector
    Mar 27 2025
    Carbs are one of the most misunderstood aspects of nutrition. For decades, they’ve been praised, demonized, and debated. Today, low-carb diets are everywhere, but the reality is more nuanced. While over 80% of the carbs we eat come from low-quality, refined sources, the right kinds of carbs are essential for good health. In this episode, Professor Tim Spector breaks down the difference between good and bad carbs and explains why quality matters more than quantity. He explores how the rise of ultra-processed foods has led to an overconsumption of unhealthy carbohydrates, contributing to energy crashes, hunger, and long-term health issues. He also explains the benefits of fiber-rich carbs, their role in gut health, and why cutting carbs entirely may not be the best approach. The episode also answers common questions about carbs, including the best time to eat them, how to pair them for better digestion, and whether alternatives like almond flour are actually healthier. Tim also shares practical tips, such as why freezing bread might be a simple way to make it better for you. 🥑 Make smarter food choices.

Great episode!

Once again, it is like Jonathan is reading my mind and asking all the questions I have! (except for the one on tomatoes...). Thank you for explaining the science and debunking the latest myth, which although one can see it's just aimed at selling a miracle cure in the form of one supplement, it's good to have the tiny doubts it raises squashed.

21st Century scientific nutrition

Science before marketing, all the topics to date have been fascinating and informative. I’ve read books by Tim Spector and Will Bulsiewicz, all very readable science. Their interest in the microbiome points the way to the medicine of the future. I could listen to both all day.
I look forward to further podcasts.

Essential information

It is staggering how we as consumers are being misled and that food producers get away with adding so much rubbish to our food and so cynically add compounds that create addictions and health risks.
These podcasts, together with Tim Spector’s books are real eye openers.

Good information, annoying posh voices!

Just listened to the programme about vitamins, and was amazed that the fact that BAME people deaths from covid were over represented and a link was made to lack of vitamin D. The advice given about vitamin D was clearly targeted at white people/those living in sunny climates. Those of us with melanin living in UK don't absorb enough vitamin D from sunshine. And if also a vegan then surely supplements should be taken? Also, there is an issue with absorption of vitamin D supplements. Even though I take supplements, my levels are still low. Why no research into why people of colour seem to not absorb vitamin D as a supplement?

If you are a female you need to hear this

The reports were skewed. The press coverage was incorrect. Millions of women have missed out on treatment. They included the data on much older females in the reports which affected the percentages.
HRT is safe. Go get some. Enjoy your life x

Excellent information

An excellent overview of fermented food. Would like to know more about the effects of salt in fermented foods on the body, particularly for people that have heart disease. Are fermented foods with salt ok for those people? Always excellent information, clearly presented.
