What Andrew Huberman recommended
In transcript order-
Yerba mate may stimulate GLP-1 release, acting as an appetite suppressant.
“yerba mate tea can stimulate the release of GLP-1
CaveatsSome reports link smoked yerba mate to certain cancers; data debatedCertaintyhedgedpersonal use -
Avoid excessive or unnecessary antibiotic use, especially in early childhood, due to detrimental effects on gut microbiome establishment.
“exposed to a lot of antibiotic treatment early in life... very detrimental
CaveatsFollow doctor's prescriptions; not anti-antibiotic when medically neededCertaintyexplicitmild caution -
L. reuteri showed ability to correct social deficits in autism mouse models via vagus nerve activation of dopamine and oxytocin.
“Treatment with L-Ruteri corrects the social deficits
CaveatsMouse model only; not yet translated to humansCertaintyspeculativeoffhand mention -
Fecal microbiota transplants have shown therapeutic effects for colitis, obesity, and certain psychiatric conditions in clinical contexts.
“significant improvement if not rescue of the colitis
CaveatsDonor health matters; recipient can acquire donor's metabolic syndromeCertaintyhedgedoffhand mention -
Avoid excessive probiotic intake as it may contribute to brain fog through SIBO and metabolic acidosis.
“excessive intake of probiotics... can lead to brain fog
Certaintyhedgedmild caution -
In a protocol
Consume 4-6 servings per day of low-sugar fermented foods with live active cultures to increase microbiome diversity and lower inflammatory markers.
“high fermented food diet... increased microbiome diversity and decreased inflammatory signals
DosageRamp up over 4 weeks; 4-6 servings (~4-6 oz each) per day; consistency over duration matters more than serving countCaveatsMust contain live active cultures; refrigerated section; not shelf-stable pickles/sauerkrautCertaintyexplicitstrong endorsement -
In a protocol
Plain (low-sugar) yogurt with live active cultures is recommended; avoid sugared yogurts.
“plain yogurt
CaveatsSugared yogurts may not have the same positive microbiome effectsCertaintyexplicitrecommendation -
Include some prebiotic fiber in diet to support fiber-digesting enzymes, though it didn't increase microbiome diversity in the Sonnenberg/Gardner study.
“ingesting a fair amount of fiber is going to be a good idea
DosageRamp up gradually over weeks to avoid gastric distressCaveatsDid not increase microbiota diversity in study; some subgroups showed increased inflammationCertaintyhedgedrecommendation -
In a protocol
Sauerkraut from the refrigerated section (or homemade) is a recommended low-sugar fermented food with live cultures.
“sauerkraut, which happens to be my personal favorite
CaveatsMust be refrigerated with live cultures, not shelf-stableCertaintyexplicitpersonal use -
Use probiotics at low-to-moderate doses normally; higher doses only when stressed, jet-lagged, after antibiotics, or under physician guidance.
“ingestion of probiotics at a fairly low to moderate level
DosageLow-to-moderate baseline; higher doses only during stress, antibiotics recovery, or travelCaveatsExcessive probiotics may cause brain fog via lactate/SIBO pathwaysCertaintyhedgedrecommendation -
In a protocol
Making your own sauerkraut at home is a low-cost way to dramatically increase fermented food intake.
DosageCabbage, water, salt; follow specific protocol; routinely scrape surfaceCaveatsMust follow protocol carefully to avoid harmful microbesCertaintyexplicitpersonal use -
In a protocol
Sauerkraut brine contains many live cultures and is suggested as a particularly potent source for microbiome diversity.
“particular value that brine might hold
Certaintyhedgedrecommendation -
In a protocol
Tim Ferriss' book contains a recommended homemade sauerkraut recipe for low-cost fermented food production.
“recipe for homemade sauerkraut that's contained in Tim Ferriss' book
CaveatsFollow protocol carefully to avoid bad microbe growthCertaintyexplicitrecommendation -
Animal data suggests saccharin and sucralose may disrupt gut microbiome, though not established in humans; consumers should weigh personal risk.
“saccharin or sucralose show disruptions in their gut microbiome
CaveatsOnly shown in animal models; not established in humansCertaintyhedgedmild caution -
Limit chronic stress as it disrupts the gut microbiome; use stress management tools to support gut-brain health.
“chronic stress, can disrupt the gut microbiome
Certaintyexplicitrecommendation
