Take a nice deep breath in… through your nose. It’s a simple way to get healthier gums, a better memory, and improved lung function. How? Well, it may partly be due to a special molecule called nitric oxide. Michael Mosley speaks to Professor Jon Lundberg from the Karolinska Institute in Sweden who made the fascinating discovery that nitric oxide is produced in your nose and travels to your lungs where it has some surprising benefits, including boosting oxygen uptake and possibly helping you fight off infections. Our volunteer Joe tries out a few tips to make nasal breathing a habit.

Health & Fitness

Michael Mosley investigates how cooking from scratch can be a simple way to eat healthier and avoid ultra-processed foods, many of which are associated with an increased risk of diseases like cancer, type 2 diabetes and heart disease. It doesn’t need to be complicated - simple recipes using tinned and frozen foods can be a great way to get started. Michael speaks to Dr Emily Leeming, a nutrition scientist from King's College London, to find out why cooking your own meals can be so beneficial for your gut microbiome, your waistline and your mental health.

Cook from Scratch

We all know that walking is hugely beneficial for our health and wellbeing, but we can get even fitter, and use nearly twice as many muscles, by introducing some poles and a simple technique. Join Michael Mosley as he delves into the science of Nordic walking to find out how it can enhance our walks by burning more calories and helping to ease back pain. He speaks to Dr Jennifer Reed from the University of Ottawa Heart Institute about her research, which has demonstrated why Nordic walking is one of the best forms of exercise for improving your heart health. Our volunteer Jessica picks up some poles and transforms her regular walks into a full-body workout.

Michael Mosley gets his flax fix, as he finds out how flax seeds, also known as linseeds, can protect your heart, reduce your blood sugar levels, and might even keep your skin feeling smooth and hydrated! With the help of Dr Grant Pierce from the University of Manitoba in Canada, Michael learns about the key components of flaxseed, including alpha-linolenic acid, and how they contribute to its array of impressive benefits. Through his research, Grant has demonstrated that daily flaxseed can lower your blood pressure and cholesterol, reducing your chance of a heart attack or stroke by a remarkable 50%! Meanwhile, our volunteer Rena finds flaxseed a welcome addition to her diet.

Humans have been making music for thousands of years, but for Michael Mosley and our volunteer Matthew, the musical journey is only just beginning. Playing a musical instrument has been shown to strengthen your memory and lift your mood. It can even reduce chronic inflammation. Dr Sofia Seinfeld from the Open University in Catalonia tells Michael why it’s never too late to start making music, and how it can enhance your cognitive abilities by activating regions of the brain associated with motor co-ordination and the processing of emotions. Meanwhile, Matthew gets to grips with the ukulele to see if he can master a tune and boost his wellbeing.

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.
