Suggested no meat at allUpdated a month ago
The food recommendations are based on peer-reviewed studies that show associations between specific bacteria and specific foods. Depending on deficiencies/overgrowth within each gut microbiota analysis, specific foods that have been shown to help modulate that bacteria will be presented within recommended foods to incorporate and recommended foods to avoid. High meat and fat diets can increase inflammatory bacteria which can have a negative effect on the gut biome and beneficial bacteria growth, therefore (depending on the sample presented) a strong plant-based diet at times is recommended. The vegetables, fruits, and legumes such as lentils, chickpea, and beans are high in carbohydrates. Additionally, legumes and nuts, and seeds are very high in protein as well. Should you need to increase specific macronutrients such as additional animal protein, occasional consumption would be a better option over daily consumption.
Bacteroidetes and Firmicutes phyla generally make up the majority of the bacteria found in the gut. Bacteroidetes are a phylum of gram negative bacteria that offer many beneficial probiotic effects as well as adverse pathogenic effects depending on the species, abundance, and location on/in the body. Pathogenic translocation can be due to a "leaky gut", compromised immune system, excessive antibiotic use, aging, and surgical injuries. While it is normal and beneficial to have Bacteroidetes in the gut microbiota, very high levels can be associated with systemic inflammation due to chronic exposure to lipopolysaccharide (LPS), a pro-inflammatory molecule derived from Gram-negative bacteria.
The prevalence of these species can depend on the diet, environment, antibiotic use, and lifestyle influencers. These are the dominant species in a high-fat, high-protein, low fiber diet (Wu et al., 2011) therefore the recommendation is often more of a plant-based diet to decrease: whole foods, high fiber, green tea, FOS or GOS foods.
