As we read on yesterday's blog post, dietary fibers alter the microbiome. On this week's episode of The Microbiome Podcast we talked in depth with Drs. Erica and Justin Sonnenburg from Stanford University about dietary fibers and their impact on our microbiota and our health. Erica and Justin wrote a book that was published today called The Good Gut: Taking Control of Your Weight, Your Mood, and Your Long-term Health. You can buy it here on Amazon and it's a highly recommended read for anyone interested in the microbiome.
We will continue answering your questions on the podcast so please call 518-945-8583 with any questions for us or for next week's guest, Dr. Elaine Hsiao.
