Beta Diversity
Beta diversity describes differences between gut microbiomes—explaining why identical diets produce different digestion and FODMAP tolerance.
Beta diversity compares how different one person’s gut microbiome is from another’s—or how your own community shifts after diet, travel, antibiotics, or training camps. Two athletes can eat similar macros yet host distinct microbes.
That is why personalized FODMAP reintroduction beats copying someone else’s elimination list.
Common questions
-
Why do twins sometimes digest the same meal differently?
Genetics, sleep, stress, prior antibiotic use, and microbial history all shift beta diversity. Meal templates still need personal trigger testing.
