What if some of the simplest ingredients in your kitchen could help support healthier ageing? Nutritionist Karen Newby joins Liz to explore the foods that deliver the greatest longevity benefits – and what to eat to support our cardiovascular, brain and bone health.


They discuss the merits of polyphenol-rich foods, fibre, omega-3s and antioxidants, and why ingredients such as extra virgin olive oil, leafy greens, pulses and berries should play a starring role in a nourishing, pro-ageing diet.


Karen also explains the importance of a healthy gut as we age, and shares simple, budget-friendly ways to add more longevity-supporting foods to everyday meals.


In this episode:

  • The benefits of social eating
  • How turmeric is a natural anti inflammatory
  • Why extra virgin olive oil is almost medicinal
  • Juicing your greens for an easy diet hack
  • The importance of a healthy gut for nutrient absorption

  • Low-FODMAP eating to alleviate digestive discomfort
  • Supporting cardiovascular health with fibre and pulses
