Dec 08, 2022•52 min•Transcript available on Metacast The acid in your stomach is so powerful it can dissolve metal. Luckily, your stomach is fine-tuned to deal with its acidic fluid, but the rest of your body isn’t quite as hardy. So, if acid escapes from your stomach and reaches your esophagus, it can cause a painful sensation in the chest — this is heartburn. It isn’t rare, with more than 1 billion people suffering from it globally. In today’s short episode of ZOE Science & Nutrition, Jonathan and Will ask: Why do we get heartburn, and what’s th...
Dec 01, 2022•18 min•Transcript available on Metacast Good information about vitamins is hard to find. With over 70% of Americans and 40% of Brits using them, it's a hugely lucrative market, which means numerous voices in the media and online pusing a pro-vitamin agenda.

While world religions have practiced fasting for millennia, the trend of fasting has soared in popularity in the last decade.

Oct 20, 2022•45 min•Transcript available on Metacast It seems like every day, someone new mentions intermittent fasting. But what is it, exactly? There are myriad options — from the 5:2 diet, with two days of extreme calorie restriction each week, to the warrior diet, which involves eating only raw fruit during the day and a mammoth feast at night.

Oct 06, 2022•15 min•Transcript available on Metacast Do our blood vessels hold the secret to long life? 60,000 miles long. That’s the length of the tube system inside us that transports blood, oxygen, and nutrients to the cells in our body. If these tubes fail, the result can be fatal. In some cases, it’s a heart attack. In others, it’s a stroke, where the blood supply to the brain is disrupted, and brain cells are damaged or killed. Heart attacks and strokes are a major cause of death in developed countries - but we can take action to reduce the ...

Sep 22, 2022•14 min•Transcript available on Metacast Our planet is overheating. Human society is creating too much carbon dioxide, stopping the sun’s warmth from escaping back into space. As earth gets hotter, its ice caps are melting, causing sea levels to rise, and submerging entire communities. Floods, droughts, and wildfires are already becoming much more common. Some effects of climate change are now irreversible, but there is still hope, and adjusting what we eat might play a bigger part than you’d imagine. In this episode, Jonathan speaks w...

Felice was the driving force behind the landmark study ...

Jul 14, 2022•16 min•Transcript available on Metacast Keto has been promoted as a magic bullet for weight loss by its supporters and slammed as dangerous by its opponents. It's no surprise - completely removing almost all carbohydrates is not what most people consider ‘a balanced diet’. With carbs off the table, Keto diets involve a dramatically increased fat intake. At the same time, drastically reducing carbs means starving our gut microbes of the fiber that feeds them. Nonetheless, doctors prescribe keto diets to treat people with severe diabete...
