❓ Frequently Asked Questions

What is gut microbiome diversity? +
Higher diversity means more types of beneficial bacteria, which is linked to better health outcomes. The American Gut Project found that people who eat 30+ different plant foods per week have the most diverse microbiomes.
How accurate is this calculator? +
This calculator uses peer-reviewed research from Nature Reviews Gastroenterology & Hepatology, the American Gut Project, and Harvard T.H. Chan School of Public Health. It provides a research-based estimate of your gut health.
What's the difference between probiotics and prebiotics? +
Probiotics are beneficial bacteria (found in fermented foods). Prebiotics are food for those bacteria (fiber, onions, garlic). You need both for optimal gut health.
How can I improve my score? +
Eat 30+ different plant foods weekly, include fermented foods daily, reduce processed foods, manage stress, sleep 7-8 hours, and exercise regularly.
