Jack asked me to pass on this correction from his talk: A reader questioned the units I was using for the vitamin D slide in which I listed the reference range of 40-50 nmol/l. After checking it out, I realized that I had failed to update the slide after the Institute of Medicine's most recent report on vitamin D levels. The reference range for vitamin D should have been 50-125 nmol/l. At an average of 55.9 nmol/l the vegans in EPIC-Oxford had adequate vitamin D status, though not well above the reference range as the slide had implied. As an aside, 95% of the vegans had vitamin D levels above 50 nmol/l. I have corrected the slide and I'd like to thank the participant who recognized something was off and bringing it to my attention! |
