ZOE Science & Nutrition

Show Notes

Fermented foods have evolved from a niche health trend into a supermarket staple. Kefir, kimchi, kombucha. Our shelves are now filled with products rich in beneficial bacteria.

But with so many options to choose from, it can be difficult to know where to begin.

Today, Professor Tim Spector shares simple, practical ways to incorporate fermented foods into your daily meals. He’ll also show why fermenting at home is much easier than most people think, taking us inside his fridge to demonstrate how to make four of his favourite homemade ferments.

Sleep. It’s a bizarre process when you think about it. We lie down, close our eyes, and before we know it, we’re waking up the next morning with a head full of hazy dreams.
