Medical Sports Nutrition

Send us a text 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....

Send us a text 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 comm...

Send us a text 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. Ref: Nash E, Nicoll A, Batt...

Send us a text 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.  Podcast 37 Radke J, Meinhardt J, Aschman T, Chua R...

Podcast 36 Kiss A, Soós S, Temesi Á, Unger-Plasek B, Lakner Z, Tompa O. Evaluation of the reliability and educational quality of YouTube™ videos on sport n...

Send us a text In this episode we run through at a small but interesting study of the impact of the menstrual cycle on the fuels the body uses. We question if we should be going to Industry funded research for our articles on benefits of carbohydrates and we then finish with a article on probiotics improving protein absorption and muscle gain in elite vegan athletes.  Lee SJL, Sim MP, VAN Rens FEC...

Send us a text 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! Podcast 34 Clauss...

Send us a text 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...

Send us a text This episode we review a couple of articles that challenge the common perceptions for coffee and fasting, and decide if they will change our practice. We look at the useful points from the new IOC REDS consensus and enjoy an interesting Fish Oil Supplement article.  Podcast 32 Svart M, Nielsen MM, Rittig N, Hansen M, Møller N, Gravholt CH. Oral 3-hydroxybuturate ingestion acutely lo...

Send us a text 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 observa...

Send us a text This week we look at a recent BMJ paper on sweeteners vs sugar for health of diabetic patients and compare to some of the past papers we have studied in this area. We enjoy an excellent short intervention study on the impact of pre-meal almonds and wait for the larger studies to follow. Finally a look at the impact of Heat on your sleep low- train low adaptations.  This podcast is a...

Send us a text A slightly noisey podcast due to nearby building work. My favourite this month was a superb Australian article proving how poor labeling is in supplements - the industry must do better than this. A review through some interesting options for pre race optimisation such as coffee mouth rinsing, defecation, topical bicarbonate, some interesting new ideas to explore. References Held S,...

Send us a text In this episode we enjoy a article that clarifies why your performance should not dip on a high fat low carb diet although we are still waiting for the proof and why the answer to your fatigue and unusual symptoms may still be 'covid' even a year post infection. In a more cheerful papers, a year of hard training is still helping with diabetic control 10 years later. Referenc...

Send us a text In this episode we look at an excellent review that attempts to help us understand nitrates. We get frustrated by studies jumping into the 'fasting vs exercise' debate and the 'plant vs fish' debate with very selective use of their data. References: Podcast 27 Gibbons TD, Cotter JD, Ainslie PN, Abraham WC, Mockett BG, Campbell HA, Jones EMW, Jenkins EJ, Thomas KN. Fa...

Send us a text Firsty a smattering of proof that flavonoids are great for managing ageing changes, but still no good evidence they help our athletes perform any better. Then a nice microbiome paper that tells us why some mice seem to be lazier than others. Can we stretch this to human athletes? Also we ask where can we shoehorn in continuous glucose monitors - it looks fancy and must be useful for...

Send us a text In short - no. But we review a series of recent articles trying to pick away at the inner workings of these markers. We try and avoid the pitfalls of black and white answers and steer around the icebergs of simplification. In addition, beetroot and blood pressure, water use and ibuprofen on the intestine. References: Lundy B, McKay AKA, Fensham NC, Tee N, Anderson B, Morabito A, Ros...

Send us a text This week we will dip a toe into Lipidomics,  the direction of cholesterol tests in the future; not just looking at lipid blood levels but using the lipid tests as a reflection of changes within our cell membranes. We then look at a state of play article for current available lipid blood tests and how to interpret panels, a keto diet study and a remind ourselves how good bariatric s...

Send us a text In this podcast we cover the evolving evidence that low carbohydrate diets are not going to kill you in the ways that we keep getting told. We also look at the 1 year impact of even mild covid and look at what form your carbohydrate needs to be in mid race (spoiler - it does not really matter as long as you can tolerate it). Below are the references for this episode in no particular...

Send us a text In this review of the current nutrition literature we look at some articles highlighting the dangers of our processed food dependency, look at a rare bird in nutrition - a well designed RCT, and discuss a LEA case report. This podcast is a lighthearted review of the medical literature and Dr Matheson has enormous respect for all scientific researchers and could not do a job as hard...

Send us a text We balance the tea/coffee debate with a large tea cohort paper review.

Send us a text This weeks review covers a fascinating case study on ApoE4 and dementia and the negative impact of long term steroid use. In addition a look at antibiotics and their effect on the immune system, and one article highlights how hard it is to get good translatable science from the lab to the gym. This podcast is a lighthearted review of the medical literature and Dr Matheson has enormo...

Send us a text More on the discordance between what is healthy for us and what gets the best performance.  If seems to be very good for our health, but performance improvements are mixed at best. Fructose added to our drinks is great for getting sugars in during a race, but terrible for our insulin sensitivity and triglyceride levels. Also will carb restriction thin our bones and a HIT study where...

Send us a text Lots of articles to run through this episode. Impact of sleep on health, best pattern to do your training, some disappointing UEFA guidelines, and a nice protein review. My search for good Hemp protein data continues. Enjoy! This podcast is a lighthearted review of the medical literature and Dr Matheson has enormous respect for all scientific researchers and could not do a job as ha...

Send us a text In this episode we catch up with some recent articles covering topics from vitamin C killing ITU patients, to the benefits of bariatric surgery. We focus on a super editorial that reminds us of how 'adults in the room' talk when discussing nutritional science - a breath of fresh air compared to twitter wars and simplifications that bombard us all the time. This podcast is a...

Send us a text The impact of Covid on the brains structure - what does it mean for the future. We also cover a recent large Spanish diet study for prevention of further heart disease, and finally some sports related papers - effect of cooling on training adaptations, usefulness of a REDS questionnaire and are reminded of the gulf between research and useful advice in the microbiome.
