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.

Send us a textFirsty 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 our patients....Apologies for forgetting the name of a leading UK Medical Nutrition Academic - of...
