Macro partitioning
Dietary acculturation to a Western diet (higher intake of red meat, trans fats, lower fiber) is associated with a lower Prevotella to Bacteroides ratio and lower fungal diversity, while a healthier diet (higher AHEI score) is associated with a higher P:B ratio.
Your diet plays a huge role in your microbiome. A healthier diet (higher AHEI score), characterized by more whole grains, vegetables, and less red meat and trans fats, is associated with a healthier P:B ratio. If you are acculturating to a Western diet, try to maintain the fiber-rich aspects of your traditional diet (beans, vegetables, whole grains) and reduce processed foods and red meat to support a diverse microbiome.
Those consuming primarily 'American' foods rather than 'Hispanic' foods (dietary acculturation) had significantly lower Prevotella to Bacteroides ratio... More favorable AHEI diet score was associated with higher Prevotella to Bacteroides ratio... Four specific foods that were associated with higher Prevotella to Bacteroides ratio were higher whole grains, higher vegetables, lower red meat, and lower trans fats.
Why this rating
Large cohort, multivariable adjustment, but cross-sectional design limits causal inference.
