The information in this book will save your life if you read it, understand the clear science and adhere to the regime...there will be no going back to eating foods that have damaged your body, caused inflammation to your gut and brain. Since adopting the change in diet I no longer suffer from depression, IBS, joint and muscle paIn, I now have energy and take no medicines no antacids, painkillers nor antibiotics...all is clearly explained how these damage our microbiome. It is well written, has good science and casebook references. I have now bought many copies to give to family and friends who are suffering from many autoimmune disorders, allergies, chronic fatigue syndrome, ME, and the long-term risk of cancer...and who are constantly battling overweight issues. I thoroughly recommend it.
