In this episode we saunter through a vitamin D guideline that provides a super summary resource, we look at why genetic testing for caffeine may be available for 'normal' athletes sooner than you think, and realise again how gender biased Sports nutrition research is.

This is the last show in this series. I do hope to have another series soon. Thank you to anyone listening. I hope you have enjoyed this as much as I have.

In this episode we look at the results in Nature Medicine of the Zoe study and think about what might have made it a stronger paper and what questions are still not answered. We talk about an antibiotic cream that may prevent viral infections and finally a Nutri-sante cohort study that shows the potential dangers of emulsifiers, which are a very common ingredient in many of our common sports supplements.

What difference will 500m make to the ideal physiology for a rower. When should you go for cold immersion and when hot. Is training harder if you are on the hormonal contraceptive pill. Could that be a good thing. We skip through these and other questions trying to see if anything is clear or as muddy as a cold tub after a rugby team had been through it.

In this episode we review a mix of sleep and menstrual cycle articles. We look at the impact of sleep on viral infections, the right length of naps and the impact of sharing rooms. Then studies looking at injuries in different stages of the cycle and confirmation that it is still not something that is discussed as openly as needed.

We run through a selection of interesting articles, all of which demonstrate key flaws that we keep seeing in nutrition research. Testing at the wrong time, wrong timeframe to followup for that testing, competing interests that blow the mind. Articles that demonstrate the researchers deeply held beliefs rather than take the science and understanding forward. Enjoy!

In this episode I review some practical changes to the way we can prescribe/recommend our athletes take iron supplements. I then sit on the sidelines and enjoy the fighting between factions on the sides of the Ultra Processed Food safety/blame war and am very glad not to be in the line of fire and feel some empathy for those involved. We finish with some articles on weight loss with different carbohydrates, the impact of fibre on cancer risk and an older article on post menopausal muscle strength.

We start with a look at a article providing further evidence BMI is unhelpful, moving onto the effect of low carb diets on bowel inflammation and then a time restricted eating study. The main player this week is the WHO sweetener review...spoiler they don't think they are good for you long term and are pushing back against the wave of industry funded positive spin on the observational studies hinting at increased long term mortality. Finally a great study on what is actually in your herbal supplement.
