Huge congrats to @seandreu.bsky.social and the whole team! 🥳 So glad to have been a part of this exciting work that focused on the links between gut #microbial #genetic variation at the #strain level and a whole slew of host #phenotypes and geography. Read more @cellpress.bsky.social!

🌟New Year, New Resolutions!🌟

🌱As we kick off the year, many people take part in challenges like Veganuary, aiming to try out a plant-based diet.

📄Let’s dive into how different diets shape our gut health and the diversity of the microbiome based on a recent paper published by @cibiocm.bsky.social

#Diets affect the gut #microbiome, e.g. red #meat is a driver of #omnivore microbiomes linked to poor cardiometabolic #health, inflammatory bowel #disease, colorectal #cancer & low short-chain fatty acids; #vegan ones are linked to favorable markers: doi.org/10.1038/s415... #plant-based #nutrition

Curious how omnivore, vegetarian, and vegan diets shape the gut microbiome?

@cibiocm.bsky.social @fackelmeister.bsky.social meta-analyzed 21,561 individuals and mapped diet-specific microbiome signatures linked to health. Plant-based diets show promising cardiometabolic benefits!

Starting the new year with a new paper out, led by @fackelmeister.bsky.social, check it out 👇

Thank you so much!

This is figure 5, which shows the contribution of food microbes to the gut microbiome across diet patterns.

A study in Nature Microbiology suggests that consuming more healthy plant-based foods could increase the proportion of gut microbes that favour human health. The findings are based on an analysis of more than 21,000 vegans, vegetarians, and omnivores. https://go.nature.com/40kHGqN 🧪

Thank you for inviting us to write this Research Briefing! It was a lot of fun and a welcome change to write in what we hope is more widely accessible format! I always enjoy reading the "behind the paper" sections because it sheds light on the authors' insight that one doesn't usually have.

Thank you! Subgroups are not something we looked into, but we did consider hPDI (healthy plant-based diet index). This correlates with the same microbes regardless of diet pattern so in theory, omn eating more veg could have similar microbes as vegans. In practice though, omn have the lowest hPDI.

This work wouldn’t have been possible without collaboration! 💪 Kudos and thanks to the team at CIBIO and ZOE (most aren't on bluesky, so not tagged here) @cibiocm.bsky.social @fasnicar.bsky.social
🥳👏 10/10

Summary: The inclusion/exclusion of major food groups leaves its mark on the gut #microbiome via potential selection & food-to-gut acquisition esp from #dairy but also from fruit/veg, highlighting the role of agricultural practices in westernized gut microbiomes. 9/10

Interestingly though, the most prevalent food microbes in vegans are soil microbes sometimes used in agriculture as N-fixing plant-growth promoters🌱 8/10

Using the database of food-specific microbes #cFMD, we found that the greatest number of microbes may be derived from dairy, then fruits/veg and finally meat. Since vegans don’t eat dairy, they harbored the fewest food microbes. 7/10

🍎🥑🥕Diversity of plant-based foods in one’s #diet can play a role in shaping the gut #microbiome, regardless of diet pattern. However, in practice, omnivores consume a significantly less plant-diverse diet than #vegans or #vegetarians. 6/10

By correlating gut microbes with various host #cardiometabolic markers, we found vegan signature gut #microbes to be most favorable in terms of cardiometabolic #health, followed by vegetarians, trailed by omnivores. 5/10

#Dairy microbes distinguish vegan from vegetarian gut #microbiomes, esp Streptococcus thermophilus, a common dairy starter. 4/10

Omnivore signature microbes are related to meat digestion🥩 & inflammatory processes (eg Ruminococcus torques, Bilophila wadsworthia & Alistipes putredinis). Vegan microbes are often fiber-degraders & short-chain fatty acid producers (eg Butyricicoccus, Roseburia hominis). 3/10

Using gut #microbiome samples from 21k+ people from the UK & US from the ZOE PREDICT cohorts (among the largest with detailed dietary info) plus Italy, we were able to accurately distinguish between omnivores, vegetarians & vegans via machine learning #ML (mean AUC=0.85). 2/10
