The 30 plants a week concept comes from research suggesting that dietary diversity is associated with a more diverse gut microbiome
Research from the American Gut Project found that people who eat 30 or more different plants per week tend to have a more diverse gut microbiome compared to those who eat fewer than 10
Different plant-based foods provide different types of fibre, vitamins, minerals, and phytochemicals. Eating a wider variety means a wider range of nutrients
Eating30 makes tracking plant diversity simple so you can build a consistent habit without calorie counting or complicated food diaries
Track your intake across fruits, vegetables, whole grains, legumes, nuts, seeds, herbs, and spices. Eating30 includes Eat the Rainbow statistics to help you see your colour variety at a glance.
The 30 plants per week concept comes from the American Gut Project — one of the largest citizen science studies of the human microbiome, analysing over 10,000 participants from the United States, United Kingdom, and Australia. The study found that people who ate at least 30 different types of plant-based foods per week had a more diverse gut microbiome compared to those who ate 10 or fewer. Eating30 was designed around this research to make tracking plant diversity simple and accessible.
Common questions about the 30 plants a week challenge and the Eating30 app
The 30 plants a week challenge is based on findings from the American Gut Project, one of the largest studies of the human microbiome. The research found that people who eat at least 30 different plant-based foods per week tend to have a more diverse gut microbiome compared to those who eat fewer than 10. Plants include fruits, vegetables, whole grains, legumes, nuts, seeds, herbs, and spices — each distinct type counts as one plant.
Eating30 is a dedicated plant diversity tracker that makes logging simple. You can add foods with minimal taps, scan barcodes on packaged foods, or use Siri voice input. The app includes a database of 500+ plants, tracks your weekly progress toward 30 different plants, shows Eat the Rainbow statistics, and syncs across your Apple devices with iCloud.
Fruits, vegetables, whole grains, legumes, nuts, seeds, herbs, and spices all count. Each distinct type counts as one plant — for example, blueberries and strawberries are two different plants. In Eating30, you can customise the rules to decide whether varieties (like purple vs orange carrots) count separately, and you can add your own plants and categories.
Yes. The core 30-plant tracking experience is completely free, including food logging, barcode scanning, Siri voice input, weekly progress tracking, achievements, and iCloud sync. Optional premium features — such as a full journal with search, prebiotics and polyphenol tracking, and saved plant combos — are available as a separate purchase.
The American Gut Project, one of the largest studies of the human microbiome, found that dietary diversity — particularly the number of different plant-based foods consumed — was associated with greater microbial diversity in the gut. Different plants provide different types of fibre and nutrients, which may support different beneficial bacteria. Eating30 helps you track this dietary diversity.
