And now study after study seems to suggest that drugs such as Ozempic and Wegovy could have all sorts of health benefits, leading some scientists to hail them a breakthrough that could transform many chronic diseases of ageing. But what’s the mechanism for these effects and is it caused by more than weight loss? The Guardian’s science correspondent Nicola Davis tells Madeleine Finlay

For the regular drinker it is a source of great comfort: the fat pile of studies that say a daily tipple is better for a longer life than avoiding alcohol completely. But a new analysis challenges that thinking and says it was based on flawed research that compares drinkers with people who are sick and sober. Madeleine Finlay hears from the study’s lead author, Tim Stockwell, a scientist at the Canadian Institute for Substance Use Research at the University of Victoria, to find out why scientists

Is there any point in taking multivitamins?

2024/07/18

Multivitamins are cheap, convenient, and provide a little bit of reassurance if our diet isn’t quite as healthy as we’d like. But a recent study of nearly 400,000 people spanning 20 years found they didn’t help users live longer, and in fact appeared to show a 4% increased mortality risk. Ian Sample hears from JoAnn Manson, a professor of medicine at Harvard Medical School, to find out what the evidence tells us about the overall health benefits of multivitamins, and how consumers can navigate this
