The Claim
In Korean adults, higher adherence to a healthful plant-based diet (hPDI) is associated with increased abundance of the butyrate-producing genus Roseburia and decreased abundance of Caproiciproducens, while higher adherence to an unhealthful plant-based diet (uPDI) is associated with increased abundance of Escherichia/Shigella and Veillonella.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In Korean adults, eating more healthful plant-based foods is linked to higher levels of the gut bacteria Roseburia and lower levels of Caproiciproducens, while eating more unhealthful plant-based foods is linked to higher levels of Escherichia/Shigella and Veillonella.
See the scientific wording
In Korean adults, higher adherence to a healthful plant-based diet (hPDI) is associated with increased abundance of the butyrate-producing genus Roseburia and decreased abundance of Caproiciproducens, while higher adherence to an unhealthful plant-based diet (uPDI) is associated with increased abundance of Escherichia/Shigella and Veillonella, suggesting specific microbial taxa may mediate diet-related metabolic effects.
When people eat more whole plant foods like fruits, whole grains, and legumes, fiber feeds good bacteria that make butyrate, which strengthens the gut lining and reduces inflammation, leading to better blood sugar control and less fat storage. When people eat more sugary and refined plant foods, bad bacteria grow that produce toxins that leak into the blood, causing inflammation and making it harder for the body to use insulin, which raises blood sugar and lowers good cholesterol.
What the research says
1 studyStudy: Plant-based diet quality and gut microbiota in relation to cardiometabolic risk in Korean adults
People who ate more healthy plant foods had healthier gut bacteria and lower risk of obesity and high blood sugar, while those who ate more sugary plant foods had worse metabolic health — suggesting gut bacteria may play a role, though the exact bacteria weren't named in the study.
