“Olive oil, common within the Mediterranean diet, helps reduce gut inflammation,” he explained.
“Try it as a salad dressing or drizzled over some cooked vegetables for a double whammy and it makes all that veg, beans and lentils taste so much better.
“Prebiotic foods form the foundation of a psychobiotic diet – a vegetable and fibre-rich one that’s good for your brain, keeps your mood up and anxiety levels at bay.
“They act as the ‘fertilizer’ for the good bacteria and encourage them to proliferate and, in time, counter the effects of more harmful bacteria.
“Leeks, onions and garlic are all prebiotics. Fermented foods like kefir, miso paste, kombucha and sauerkraut all help strengthen the good bacteria in the gut, while fruit, vegetables and whole foods rich in fibre feed the gut microbiome and allow it to thrive.”
