Taking good care of your teeth can prevent tooth decay and boost your oral health - but, surprisingly, the benefits extend well beyond your mouth. Keeping your teeth and gums clean can help your heart and your brain, reducing the risk of diseases from diabetes to dementia. To find out why, Michael Mosley speaks to Dr. Sim Singhrao from the University of Central Lancashire School of Dentistry. She reveals bacteria in your mouth can travel from your gums into your blood causing problems in other organs, including your brain. Meanwhile, our volunteer Lowri has a go at brushing and using interdental brushes every day to see if it’s something she’d like to fit into her lifestyle.

Michael Mosley discovers that enjoying more olive oil in your daily diet can come with a whole host of surprising benefits, including protecting your brain, improving your memory and reducing chronic inflammation. The Mediterranean diet has been shown to be one of the healthiest in the world, and a major component of this is olive oil. Dr Bill Mullen from the University of Glasgow tells Michael about his recent research, which found that two tablespoons of olive oil a day can significantly reduce biological markers of heart disease. Meanwhile our volunteer Ellen, an avid home cook, reaps the benefits of switching to olive oil.

Enjoy Olive Oil

There’s no question that exercise is important for our health, but many of us find it difficult to fit into our busy schedules. In this episode, Michael Mosley explores how high-intensity interval training, HIIT for short, might be the most time-efficient way to get fitter.

Martin Gibala, Professor of Kinesiology at McMaster University in Ontario, reveals all about the beneficial impact of HIIT on your cardiorespiratory system, your ability to control your blood sugar levels, and your risk of chronic diseases. Meanwhile, busy mum and NHS worker Suzanne finds HIIT a great way to incorporate a workout into her hectic routine. Series Producer: Nija Dalal-Small

Get Gardening

It’s time to dig out that skipping rope, as Michael learns that the popular childhood pastime could have big benefits for health and wellbeing, especially as we get older. Professor Urs Granacher from the University of Freiburg, shares how skipping is a form of jumping exercise, which could help increase not just our speed, but could also help us age healthily. These exercises help increase muscle power and can also strengthen our bones. Our volunteer Shona, a new mum based in Shetland, uses skipping as an excuse to get outside.
