A Danish study has found that people who eat meat have a health-related advantage over vegans in the form of a more varied gut microbiome, according to Omni – Alla nyheter. Alla perspektiv., which cites the newspaper Berlingske. Professor Oluf Borbye Pedersen is behind the finding, which was reported on Saturday, 31 October 2026.
The result runs against the usual dietary advice, which recommends eating less meat and more plant-based food. Omni – Alla nyheter. Alla perspektiv. reports that the study has drawn attention in the research community.
Why it matters
Public health guidance in many countries has for years pushed consumers toward plant-based eating. Omni – Alla nyheter. Alla perspektiv. notes that research has linked such diets to lower blood sugar, lower cholesterol and reduced inflammation.
The new finding does not overturn those benefits. Instead, it identifies one measure on which vegans appear to come up short: the number of different bacterial species living in the gut. A broader mix of bacteria is described in the reporting as a health advantage.
If the result holds up, it complicates a message that has been presented to the public in fairly simple terms. Diet advice would need to account for the possibility that cutting out meat entirely carries a trade-off, not only benefits.
What the study compared
According to Omni – Alla nyheter. Alla perspektiv., Pedersen based his conclusion on a comparison of samples taken from 150 people. The samples were used to assess the composition of the participants' gut flora.
Pedersen's working explanation for the gap is protein intake. In his theory, the difference in bacterial diversity between meat eaters and vegans stems from how much protein the two groups consume. The reporting does not specify what kinds of meat were eaten, how long the participants had followed their diets, or how the samples were analysed.
The term gut flora refers to the community of microorganisms that live in the digestive tract. The diversity of that community — how many different kinds of bacteria are present — is the specific measure at issue here, not the overall health of the participants.
A debated area of nutrition science
Gut microbiome research has become one of the more active corners of nutrition science, and it is also one of the least settled. Findings often depend on sample size, study design and the population observed, and results can be difficult to reproduce.
The Danish work is described as a comparison of samples rather than a long-term trial, and the protein explanation is presented as a theory rather than a confirmed mechanism. Omni – Alla nyheter. Alla perspektiv. frames the result as a surprise to researchers, which suggests it has yet to be absorbed into mainstream dietary guidance.
For consumers, the practical picture remains unresolved. The established benefits of plant-heavy diets — the lower blood sugar, cholesterol and inflammation cited in the reporting — are not disputed by the new finding. What is now in question is whether those gains come at a cost measured in microbial variety.
What to watch
Expect scrutiny of the sample size, the diet histories of the 150 participants and whether other research groups can replicate the result. Until then, the finding stands as a single study's challenge to a broad recommendation, reported by Omni – Alla nyheter. Alla perspektiv. and attributed to Pedersen.
