Influence of food consumption patterns and Galician lifestyle on human gut microbiotaOriginal paper
Karen Pendergrass is a microbiome researcher specializing in microbiome-targeted interventions (MBTIs). She systematically analyzes scientific literature to identify microbial patterns, develop hypotheses, and validate interventions. As the founder of the Microbiome Signatures Database, she bridges microbiome research with clinical practice. In 2012, based on her own investigative research, she became the first documented case of FMT for Celiac Disease, four years before the first published case study.

Researchers examined how diet and lifestyle in Galicia, Spain relate to gut microbiota composition. Thirty one volunteers were selected based on set inclusion and exclusion criteria.
How was it studied?
Participants reported diet history, lifestyle patterns, and adherence to the Southern European Atlantic Diet. Fecal samples were analyzed by real-time PCR to quantify bacterial groups.
What did they find?
Volunteers ate more fruits, vegetables, legumes, and fish, and less bakery and precooked food, than typical Spanish consumption data. Most participants showed intermediate to high adherence to the Atlantic Diet, and gut samples showed high total bacteria and Actinobacteria, with elevated Lactobacillus spp. and Bifidobacterium spp. Gut microbiota also differed by body weight, age, and degree of diet adherence.
Why it matters
The findings link a regional whole-food dietary pattern to a gut microbiota profile rich in bacteria often associated with metabolic health. This supports diet as a lever for shaping the gut microbiome in a defined population.
