The Oral Microbiome & Intestinal Health

Dr. Ali Arjomand, PhD presented “The Oral Microbiome & Intestinal Health: What are we learning and what we can do” at the SCDROCKS Conference 2023 hosted by the Specific Carbohydrate Diet Association at Bellevue College. Video Objectives: What is the Oral Microbiome, What does it do, What things affect it, The Oral-Gut Axis, What it means for IBD, Takeaways!

Coming soon – my video replay at the SCDROCKS 2023 Conference in Bellevue, Washington

In the meantime, many of you asked for a list of scientific references that I presented during my talk.
