What else is featured in our March 2025 issue? This fantastic paper by Tinnion et al explores blood alkalosis and sodium citrate ingestion?? What did the authors have to say about the work? ‘Commencing exercise around individual time-to-peak (TTP) blood alkalosis (when buffering capacity is theoretically maximised), represents a practical strategy to manage the wide inter-individual variation in the response to commonly ingested buffering agents. While this strategy has shown promise for those ingesting sodium bicarbonate, this study found that the TTP response following sodium citrate was NOT RELIABLE. However, the magnitude of (and displacement in) blood alkalosis WAS RELIABLE – pointing practitioners back in the direction of a more informed, generalised approach to sodium citrate ingestion.’ Check out the full paper here! ?? https://lnkd.in/egS8uQEc

What’s the contribution of whole-food and supplemental derived dietary protein to daily protein intake in young adults? ???? We have just the paper to answer your question! ?? Freyja Haigh et al in Exeter and Wageningen have completed this fantastic cross-sectional analysis and we are lucky enough to feature it in our March issue. Read a quick summary below before hitting the link to read the full paper. ??https://lnkd.in/eacdgy8a ________________________________________________________ 1?? What they did: ? Completed a detailed analysis of habitual dietary protein consumption in a large cohort of resistance trained and recreationally active young individuals in the UK. With the aim of fully characterising dietary protein intakes across meal moments with the focus being on source (i.e., animal vs. nonanimal) and form (i.e., whole-foods or (more) isolated supplemental forms). 2?? What they found: ?? Irrespective of training status, protein distribution followed a skewed pattern with the majority of protein consumed at dinner. ??The consumption of animal versus nonanimal protein was ~ 60 vs. 40% respectively. However, interestingly, this was driven by males. ??The vast majority of protein was consumed in whole-food form. However, resistance trained individuals consumed more supplemental protein at snack moments (30% vs. 7%). 3?? Why is this interesting?: ??Current (sports nutrition) dietary protein guidelines are underpinned primarily from studies investigating isolated (supplemental) animal derived proteins, which does not reflect what is commonly consumed by young adults in the UK. Therefore, more mechanistic studies are required to investigate protein-rich whole-foods from a range of animal and non-animal sources.

Featured in our March issue by Tiller et al. - What’s (Not) in Your Supplement? ?? An Energy and Macronutrient Analysis of Commercially Available Carbohydrate Gels ‘Measured energy and carbohydrate content of eight commercial gels expressed as a percentage of values declared on the label. The shaded area represents the 20% upper- and lower limits permitted by US, Canadian, and European governing bodies. ■=Energy; ○=Carbohydrates.’ Want to know more?
