More than half of us have high cholesterol — and new research suggests that having even slightly raised levels in our 30s could significantly increase our chances of developing heart disease. Medication is a common fix, but it comes with side effects. So, today we’re looking at how much changing our diets can help. In this short (ish) episode of ZOE Science & Nutrition, Jonathan and Sarah ask: Can we lower our cholesterol by changing our diets? Follow ZOE on Instagram: https://www.instagram....

The last decade saw a rise in gluten-free diets. But the number of us with diagnosed gluten intolerance each year hasn’t changed. Eliminating gluten is the only treatment for those with celiac disease, but the rest of us could be doing more harm than good by embracing ultra-processed, gluten-free foods. In today’s short episode of ZOE Science & Nutrition, Jonathan and Will ask: Should you be worried about gluten? Studies referenced in the episode: ‘Health Benefits and Adverse Effects of a Gl...

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’...

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.

In a lab in Ireland, a group of scientists stand around a stainless steel table. One of them is holding a device, not unlike a small turkey baster. His free hand plunges into a box on the table and retrieves a mouse. Using his device, he administers the brown solution within…rectally. This unfortunate soul has just received a fecal microbiota transplant. The donor was not another mouse but a human being. And the person in question had symptoms of severe depression.

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. Whatever the approach, intermittent fasting involves restricting the window of time when you eat. Supporters evangelise the benefits, promising weight loss, disease prevention, and even life extension. ...

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 ...

Our planet is overheating. Human society is creating too much carbon dioxide, stopping the sun’s warmth from escaping back into space.

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...
