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.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-11-06:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 2.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 2 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 57.
  • The number of mentions in news outlets: 7 (Altmetric).
