30 Plants Challenge
Track every distinct plant species. Variety, not quantity, drives microbial diversity — the single best predictor of a resilient gut.
McDonald et al., 2018 — mSystems (American Gut Project)Personalized gut-brain wellness
Your gut quietly shapes your mood, focus, and future.
Veliome turns the new science of the microbiome into a daily practice — 30 plants a week, fermented foods, and the small lifestyle choices that move the needle on inflammation, energy, and brain fog.
Backed by 30+ peer-reviewed studies

What the research actually shows
Most adults eat fewer than 12 different plants a week. The richest microbiomes belong to people eating 30 or more.
30+
different plants per week is the diversity threshold linked to the healthiest gut microbiomes (American Gut Project).
60%
of calories in the typical Western diet come from ultra-processed food, the strongest dietary predictor of all-cause mortality.
95%
of your body's serotonin is produced in the gut, putting the microbiome at the center of mood regulation.
10 weeks
of daily fermented food increased microbial diversity and decreased 19 inflammatory proteins in a Stanford trial.
A complete system for a healthier gut
Every feature exists to make one part of the microbiome research actionable.
Daily Fermented Foods
Kefir, yogurt, kimchi, kraut, miso, kombucha, sourdough. The most underused lever for gut diversity and lower inflammation.

4. Track outcomes
Watch your Gut Score, mood, and energy charts move. Optional test kit deepens the picture every 6 months.
The science behind every feature
Veliome is built on peer-reviewed microbiome research from the last decade. Every claim links to a primary source.
Plant diversity → microbial diversity
The American Gut Project analyzed 11,336 stool samples and found that people consuming 30+ different plants per week had significantly more diverse gut microbiomes — and lower antibiotic resistance gene counts — than those eating 10 or fewer.
McDonald et al., mSystems 2018Fermented foods lower inflammation
In a 10-week randomized Stanford trial, healthy adults who added 6 daily servings of fermented foods to their diet increased microbial diversity AND decreased 19 inflammatory proteins, including IL-6 — implicated in chronic disease.
Wastyk et al., Cell 2021Mood lives in the gut
Roughly 95% of the body's serotonin is produced in enterochromaffin cells lining the gut. Specific bacteria (spore-forming, including Clostridium and Turicibacter) directly regulate its biosynthesis. The vagus nerve carries gut signals to the brain in minutes.
Yano et al., Cell 2015 · Cryan et al., Physiological Reviews 2019Ultra-processed food (UPF) and the gut
UPFs reduce microbial diversity, drive inflammation, and override satiety. They now make up ~58% of calories in the US and 60% in the UK. Higher UPF intake is independently associated with all-cause mortality in large prospective cohorts.
Monteiro et al., 2019 · Pagliai et al., 2021Oral microbes affect the brain
Porphyromonas gingivalis, the bacterium behind chronic periodontitis, has been identified in Alzheimer's brain tissue and CSF. Daily flossing and tongue care reduce oral pathogen load and systemic inflammation.
Dominy et al., Science Advances 2019Personalized response is real
The PREDICT-1 study (1,098 deeply phenotyped individuals) showed that postprandial glucose, insulin, and triglyceride responses to identical meals vary dramatically between individuals — and microbiome composition is one of the strongest predictors of that variance. Generic diet advice fails because it ignores you.

Members are already seeing it
I had no idea variety mattered more than quantity. The 30-plant tracker reframed everything. I went from 8 plants a week to 34 in three weeks — and finally flat by 9am.
The mood-meal correlation chart was the unlock. I stopped fighting the afternoon crash and started preventing it.
My gastroenterologist asked what I'd changed. I showed her the Gut Score graph. She downloaded the app that afternoon.
Frequently asked questions
Is Veliome a medical device or diagnosis tool?
No. Veliome is a wellness app designed to make microbiome research actionable. It does not diagnose, treat, cure, or prevent any disease. For medical conditions, consult a clinician.
Do I need the test kit to use the app?
No. The free and premium tiers work without any lab test. The kit is an optional add-on that provides a personalized bacterial profile and individualized food list.
Which scientists' work inspired Veliome?
The app is heavily informed by Prof. Tim Spector (King's College London / ZOE / PREDICT), Justin Sonnenburg (Stanford), John Cryan (APC Microbiome Ireland), and the broader American Gut Project consortium. All claims link to primary peer-reviewed sources.
How does the 108-language support work?
Both the app and this website are translated using OpenAI's gpt-4o-mini model. The website pre-renders one HTML page per language for full search-engine indexing.
Is my data private?
Yes. Veliome doesn't require an account. All food logs, mood entries, and metrics are stored on your device — we don't operate a server that receives or stores your personal data.
Will Veliome work if I'm vegan / keto / Mediterranean?
Yes. Veliome is dietary-pattern agnostic. The 30-plants principle and fermented-food guidance enhance any eating style.
How is this different from MyFitnessPal or Yuka?
MyFitnessPal tracks calories. Yuka rates products in supermarkets. Veliome is purpose-built around microbiome science: diversity, ferments, UPF load, and the gut-brain axis — not calorie counting.
Where can I read the studies?
Every science card on this page links to its primary source. The full reference list lives at the bottom of the Science section.
