The Health Edge: Sulfation in Human Biology

3 Comments

In this previously published episode of The Health Edge John and Mark discuss the fascinating process of “sulfation”, the attachment of sulfur to molecules throughout the human body e.g. lining of our blood vessels, vitamin D and cholesterol as the “carrier”. They explore the importance of getting adequate sulfa in our diets.

      Hi Joe,
      Thanks for listening in to The Health Edge and thanks for your question. It’s very confusing with all the conflicting narratives out there. A very good and objective source of information on sunscreen safety can be found with The Environmental Working Group (www.ewg.org/sunscreen/)
      It can be very hard to prove cause-effect as these toxins in isolation may appear less harmful at low levels. The problem is people confront multiple toxins that can, in predisposed individuals, be cancer promoting (e.g. retinyl palmitate in sunblocks) or disrupt endocrine function (oxybenzone). I would pay little attention to the conclusions raised by the author of the link you provided; explore the ewg info on sunblocks, and draw your own conclusions. Short of risking a sunburn, get as much sun as possible (30-60″/day unprotected unless very fair and you burn easily); wear protective clothing, and use sunblocks that are sprays and do not contain insect repellants, oxybenzone, or retinyl palmitate).

      One of the nation’s experts on sunshine risk-benefit is Dr. Michael Holick MD, PhD at Boston University. An enlightening video can be found at: https://www.youtube.com/watch?v=hiGBVDcbFVk

    Thank you for the gift of this podcast series! I am a public health RD and hugely value the learning ops, both for optimizing my own health and helping my clients. I have been listening today to your 2-part series focusing on gluten and grains, would love to hear from y’all as well on dairy foods and health.
