How does soil health intimately and profoundly impact human health? What's the link between the soil microbiome and the human gut microbiome? How can we begin to restore our health, and the health of the living earth in concert with each other?  These are the questions posed by the outstanding book 'What your Food Ate: How to heal our land and reclaim our health' and the co-authors, Anne Biklé and David Montgomery are this week's guests as we delve deeply into the nature of soil, the functions of fungi, the populations of bacteria we depend on that inhabit our guts, and how we might affect total systemic change in the food and farming system.  So a little light listening for your day. In detail, Anne Biklé is a biologist, avid gardener. She is among the planet’s leading experts on the microbial life of soil and its crucial importance to human wellbeing and survival. She is married to David Montgomery, who is a professor of Geomorphology at the University of Washington. David has studied everything from the ways that landslides and glaciers influence the height of mountain ranges, to the way that soils have shaped human civilizations both now and in the past. All of this has led him to write a number of books, including Dirt: The Erosion of Civilisations which explores how our historic - and contemporary - farming practices have critically undermined the living soil on which we depend. Following this, David and Anne co-wrote, The Hidden Half of Nature: The Microbial Roots of Life and Health and the book we're going to be exploring in depth today:  What your Food Ate: how to heal our land and reclaim the our Health.  David also plays in the band, Big Dirt, which is, and I quote directly from their Facebook page: Americana Alternative. Whatever that means. Roots folk-rock with something to say and fun to listen.I read What your Food Ate earlier this year and if you've listened to the podcast for any length of time, you'll have heard me mention it more than once. It's the most readable exploration I've come across of how our food is grown, and how it could - and should be grown - it's really easy to read, but it's full of the kind of mind-blowing data that we need if we're going to change our habits. You'll hear more in the podcast, but truly, the detail they gathered on the difference in content between food grown in the modern agri-business farm and that grown on a regenerative farm with no chemical inputs and no or minimal ploughing, one that strives to build the soil health and so build the health of everything else... it's both terrifying and inspiring. If you want something to persuade you that you need to change the places you buy your food, this is it. So, here we go. People of the Podcast, please welcome Anne Biklé and David Montgomery. Dig2Grow Website https://www.dig2grow.com/Buy the Books: https://www.dig2grow.com/booksBig Dirt https://www.reverbnation.com/bigdirtmusic
