17 Jul 2019 --- Research has found an association between diet quality and microbiome composition in human colonic mucosa. The study from Baylor College of Medicine in Houston, Texas, US found that a high-quality diet is linked to more potentially beneficial bacteria, while a low-quality diet is associated with an increase in potentially harmful bacteria. Published in The American Journal of Clinical Nutrition, the study sheds light on the diet-health connection with the researchers proposing that modifying the microbiome through diet could be part of a strategy to reduce the risk of chronic diseases.
