Feed Your Microbiome: The 30-Plant Rule
Why diversity of plants — not probiotics — is the most important lever for gut health.
The single strongest predictor of a healthy gut microbiome is the number of different plant foods eaten per week. The American Gut Project found 30+ is the threshold.
What counts
Vegetables, fruits, whole grains, legumes, nuts, seeds, herbs, and spices. Every variety counts as one.
Easy wins
Mixed bean blends, seed mixes, leafy green variety, herb sprinkles. A single salad can easily contain 8–10 different plants.
Fermented foods
Add one daily — yogurt, kefir, sauerkraut, kimchi. They diversify and modulate the microbiome.
