I listened to this podcast earlier this year and found the gut microbiome research presented to be very informative and read the book the Good Gut shortly after

The Good Gut is a book I recommend to anyone interested in learning more about their digestive health. It is easy and enjoyable to read with doable, practical research based advice given by the scientists themselves. One of the recommendations is to eat fermented foods such as yogurt on a daily basis. There are various foods listed including sauerkraut, kefir and kombucha. I have been able to implement eating yogurt on a more regular basis. I started avoiding yogurt in the past decade or so, because the lower fat content and increased protein with ‘greek’ style yogurts was causing stomach upset. I tried coconut yogurt in earlier iterations and it was awful! I am pleased to report that coconut yogurt has improved immensely and I can recommend a few- Presidents Choice Organic Coconut Yogurt alternative and Riviera coconut milk vegan delight are a thinner texture yogurt and Simpla is a tasty, thick texture.
Digestive health is a daily maintenance project that you can monitor easily by observing what comes out the other end after eating and digestion. Choosing more vegetables and fruit, being conscious of eating enough fibre, being hydrated and having a bit of extra help with friendly bacteria in fermented foods goes a long way in improving and maintaining digestive health. Eating healthy food is one part and digesting, assimilating, and absorbing nutrients is the other part of the equation and having the right balance of friendly bacteria makes the process smoother from one end to the other.
