Diet 

Studies and statistical analyses have identified the different bacterial genera in gut microbiota and their associations with nutrient intake. Gut microflora is mainly composed of three enterotypes: Prevotella, Bacteroides, and Ruminococcus. There is an association between the concentration of each microbial community and diet. For example, Prevotella is related to carbohydrates and simple sugars, while Bacteroides is associated with proteins, amino acids, and saturated fats. Specialist microbes that break down mucin survive on their host's carbohydrate excretions. One enterotype will dominate depending on the diet. Altering the diet will result in a corresponding change in the numbers of species.

Vegetarian and vegan diets 
While plant-based diets have some variation, vegetarian and vegan diets patterns are the most common. Vegetarian diets exclude meat products but still allow for eggs and dairy, while vegan diets exclude all forms of animal products. The diets of vegetarian and vegan individuals create a microbiome distinct from meat eaters, however there is not a significant distinction between the two. In diets that are centered around meat and animal products, there are high abundances of Alistipes, Bilophila and Bacteroides which are all bile tolerant and may promote inflammation in the gut. In this type of diet, the group Firmicutes, which is associated with the metabolism of dietary plant polysaccharides, is found in low concentrations. Conversely, diets rich in plant-based materials are associated with greater diversity in the gut microbiome overall, and have a greater abundance of Prevotella, responsible for the long-term processing of fibers, rather than the bile tolerant species. Diet can be used to alter the composition of the gut microbiome in relatively short timescales. However, if wanting to change the microbiome to combat a disease or illness, long-term changes in diet have proven to be most successful.

Malnourishment 
Malnourished human children have less mature and less diverse gut microbiota than healthy children, and changes in the microbiome associated with nutrient scarcity can in turn be a pathophysiological cause of malnutrition. Malnourished children also typically have more potentially pathogenic gut flora, and more yeast in their mouths and throats. Altering diet may lead to changes in gut microbiota composition and diversity.

 Studies and statistical analyses have identified the unlike bacterial genus in gut microbiota and their associations with nutrient consumption. Gut microflora is chiefly composed of three enterotypes: Prevotella, Bacteroides, and Ruminococcus. There is an association between the assiduity of each microbial residential district and diet. For example, Prevotella is related to carbohydrates and simple sugars, while Bacteroides is consociate with proteins, amino acids, and saturate fats. Specialist microbes that break down mucin survive on their host's carbohydrate elimination. One enterotype will dominate depending on the diet. Altering the diet will leave in a corresponding change in the number of coinage. 

 Vegetarian and vegan diets 
 While plant - based diets have some variation, vegetarian and vegan diets traffic pattern are the most common. Vegetarian diets exclude meat products but still allow for eggs and dairy, while vegan diets exclude all forms of animal products. The diets of vegetarian and vegan individuals create a microbiome distinct from meat eater, however there is not a significant eminence between the two. In diet that are centered around meat and animal products, there constitute high abundances of Alistipes, Bilophila and Bacteroides which are all bile tolerant and may promote excitement in the gut. In this type of diet, the group Firmicutes, which is associated with the metabolism of dietary plant polysaccharides, is found in depleted concentrations. Conversely, diets rich in plant - based materials are associated with capital diversity in the gut microbiome overall, and have a greater abundance of Prevotella, responsible for the retentive - term processing of fibers, rather than the bile kind species.

However, if want to change the microbiome to battle a disease or illness, long - term changes in diet have proven to be about successful.
