-varied diet - in particular the number of different plant species consumed is linked to microbiome diversity (although a person might need to overcome infection induced gut issues before many foods are tolerated)
What are those plants?in essence = all plants
what they are finding is the diversity of the gut microbiome is highly associated with the number of different unprocessed or minimally processed plants that we eat
in particular its the different forms of fibre (and to some extent other less abundant plant compounds like polyphenols) that are the major driver of microbiome diversity - and diversity is at the moment the best measure we have of healthy microbiome
in terms of the mechanisms involved - it seems that each plant species has slightly differing forms of fibre compounds in it - with different chemical structures and bonds and each favour different microbial species that live on them and break them down - and so the most diverse microbiomes are those living on the widest variety of food source substrate - ie most diverse mix of plant fibres
this theory comes from Professor Tim Spector - of Kings College London - who is currently one of the most influential scientists in the world of microbiome science - and founder of the ZOE program that gathers data from its huge cohort of participants then publishes findings on interventions and the microbiome and subsequent health outcomes.
its a bit like the soil and trees and shrubs of a rainforest vs a field of mono-crop wheat or rice
the rainforest has huge diversity of life due to the huge variety of substrates for everything to live on and keep sitself in balance
whereas the monocrop of wheat is nearly devoid of all other life ad needs constant application of chemicals for it to survive
Spector proposes everyone should aim to eat 30 different plants each week to promote microbial diversity in the gut and thereby improve overall health.
which sounds like a lot - but lots of things you don't initially recognise as plants count
eg nuts, dark chocolate, herbs, tea, coffee etc
of course, this can be tricky in people with Lyme and co as we often have gut issues like leaky gut and or SIBO that can make us sensitive to many foods and even fibre.
but its useful to know what the principles are.
