A friendly reminder for Healthcare Professionals who haven’t yet completed this survey. Please do so by Friday, 16th May. Start here: lnkd.in/ePuGcDge
@yourheights and @nnedpro are currently running a survey of Healthcare Professionals to understand how they provide nutrition advice to patients. If you have a spare 20 mins your time is greatly appreciated! forms.gle/ef5W56s6hYwACEjY7

How does exercise and fitness promote healthy brain aging?
An outstanding, comprehensive review @TheLancet
reduced neuroinflammmation, preserves blood-brain-barrier, neurogenesis, role of exerkines, and much more

Today we publish an (in my opinion) important paper in @NatureMicrobiol 🍾showing that gut physiology and environment are factors explaining substantial variations in human gut #microbiome composition and #metabolism🦠
Fantastic work @nicolaproch et al. 👏

We think that all memory is stored in the brain. But our study published today in @NatureComms shows that all cells—even kidney cells—can count, detect patterns, store memories, and do so similarly to brain cells. My first (co)corresponding author paper!🧵nature.com/articles/s41467-0…

📢Given the fact that #GutMicrobiome varies between person, race, ethnicity, nationality, & even neighboring communities⏩What constitutes a #Healthy #Microbiome❓What is gut microbial #dysbiosis❓🦠
🚨Excellent review “What defines a healthy gut microbiome? @Gut_BMJ 🆕🔥
⏬Dive into to learn more about the most recent advances to fully understand and define a healthy gut microbiome💡
🎯#Functional capabilities of the microbiome may be more indicative of #health than its specific #composition ‼️
✳️Challenge in distinguishing #causation from #correlation between gut microbiome & overall health✨
