The Surprising Link Between Your DNA And Your Gut

June 17, 2026 · 24 min

Show notes

Can your genes influence what you eat, how your gut works, and even why coriander tastes like soap to some people? This week on Well, food and nutrition scientist Dr Emma Beckett cuts through the noise around gut health and explains what the science actually says.

From probiotics and Greek yoghurt to taste receptors hidden throughout your gut, we unpack the surprising ways genetics shape our relationship with food. Dr Beckett reveals why one-size-fits-all nutrition advice doesn't work, what the microbiome can (and can't) tell us about health, and why the wellness industry's obsession with gut hacks may be missing the point.

Plus, Dr Mariam answers a listener's question about constipation, ageing and menopause, and explains why some gut symptoms deserve a closer look.
