Dr. Jack Kruse is a practicing neurosurgeon and also a "theoretical quantum biologist." He specifically has an interest in our light environment, circadian rhythm and mitochondria in relation to health and disease.
In my opinion, these are topics that require more attention and research in the context of Crohn’s disease and ulcerative colitis.
This is one of the most high level podcasts I have ever recorded as Dr. Kruse’s knowledge base regarding these topics is unparalleled.
You will hear things in this interview that will make you rethink some of your assumptions about what you think you know about how the human body works. We overall need to do this more often for there to be progress in the treatment of IBD.
Resist the temptation to immediately believe or disbelieve anything that we discussed but actually go into the literature. See for yourself if Dr. Kruse is right. I did this myself on some of these topics..
As a disclaimer, nothing in this podcast should be interpreted as medical advice from my perspective. None of these interventions have been investigated in the context of clinical trials to determine if they affect actual clinical outcomes in IBD. Also increasing sun exposure with IBD, especially while on certain immunosuppressive medications and biologics, comes with the controversial but theoretical risk of skin cancer.
