Abstract

Although there is associative proof linking fecal microbiome profile to fitness and disease, many researches have no longer regarded the confounding consequences of dietary intake. Consuming meals presents fermentable substrate which sustains the microbial ecosystem that resides with most abundance in the colon. Western, Mediterranean and vegetarian dietary patterns have a position in modulating the intestine micro biota, as do trending restrictive diets such the Palaeolithic and ketogenic. Altering the quantity or ratio of carbohydrate, protein and fat, especially at the extremes of intake, influences the microbiome. Diets excessive in fermentable carbohydrates aid the relative abundance of bifid bacterium, Prevotella, Ruminococcus, Dorea and Roseburia, amongst others, succesful of degrading polysaccharides, oligosaccharides and sugars. Conversely, very excessive fats diets expand bile-resistant organisms such as Bibliophile and Bactericides.
