Effect of the Consumption of Lean Red Meat from Beef (Pirenaica Breed) Versus Lean White Meat (Chicken) on the Gut Microbiota: A Randomized Cross-Over Study in Healthy Young Adults.
Trial report in Molecular nutrition & food research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Limited evidence exists regarding the impact of meat consumption on the human gut microbiota, with factors such as animal source, production system, and cooking methods often overlooked. This study evaluates the effect of Pirenaica breed beef or conventional chicken-based diets on the gut microbiota of healthy adults. A randomized cross-over controlled trial with two 8-week periods, separated by a 5-week washout, is carried out. Participants consume either Pirenaica breed beef or chicken three times per week with their diet. Stool samples are collected at the beginning and end of each period. Gut microbiota is analyzed via amplification and sequencing of V3-V4 regions of 16S rRNA. Alpha diversity and relative abundances at phylum and genus levels are calculated. Sixteen participants are included (mean age 20.12 ± 2.36 years). Both diets induce modest changes in microbial composition, with no significant differences between groups. At the phylum level, Bacillota increased, while Synergistota, Chloroflexota, and Pseudomonadota decreased. Alpha diversity parameters declined significantly after the chicken-based diet, although overall reduction in microbial diversity was observed across both interventions. The consumption of lean red meat or lean white meat as part of habitual diet produces similar effects on the gut microbiota.
