Once again I attended the International Sport and Exercise Nutrition Conference, this time as a PhD student running around with microphones, taking coats and packing bags. As with last year, and the year before, the speakers were brilliant, with experts flying in from Australia, America and elsewhere to talk in Newcastle.
My outstanding lecture of the conference was in the health theme, and focused on vitamin D. Some of the interesting points of note were:
- vitamin D can only be made in the body with exposure to UV-B rays, and these rays only penetrate Britain for 6 months of the year
- just 6 minutes of sun exposure without sun cream is needed for vitamin D production
- 1 in 5 British people are vitamin D deficient, if considering <25nmoles/l as a cut-off
- overweight and obese people have a lower vitamin D status and respond less to vitamin D supplementation than those of normal weight
New research is going into “bio-modification” to naturally enrich our diet with vitamin D. Newcastle University is starting a trial on vitamin D-enriched eggs in an effort to improve vitamin D status over the winter months. I’m participating in this trial, so stay tuned for results!
I wish you all a happy and healthy 2017!
