Gut Phyla

There has multiple different organisms which helps with the secretion and digestion system. These microorganisms include over a thousand species of bacteria, viruses and parasites. Bacteria and enzymes break down so that bile acids can be reabsorbed and recycled by the liver. Gut contains the largest immune system organ. Short-chain fatty acids, the byproducts of beneficial gut bacteria, have significant effects on your immune system. They protect your gut barrier, which prevents the bacteria and bacterial toxins on the inside from leaking into your bloodstream. They’re also anti-inflammatory for your gut.

Phylums

There are 5 major phyla for human gut microbiota; Firmicutes, Bacteroidetes, Actionobacteria, Proteobacteria and Verrumicrobiome. Bacterial stimulation is essential for the development and function of the intestinal barrier.

Firmicutes

Help digest complex carbs and extract energy

Foods that support Firmicutes

Fermented food; yogurt, kefir, sauerkraut, kimchi
Prebiotic fibre sources; bananas, oats, barley, whole grains
Polyphenol-rich foods; dark chocolate, berries, green tea

Bacteriodes

Major fiber degraders; can increase with plant-rich diets

Foods that promote Bacteriodetes;

High-fiber vegetables; broccoli, spinach, carrots
Legumes; lentils, chickpeas, black beans
Whole grains; brown rice, quinoa, oats
Resistant starch; cooled potatoes, green bananas

Actinobacteria

Beneficial for gut development, SCFA production, immunity

Foods that increase Actionobacteria;

Dairy products; yogrt, kefir, buttermilk
Plant foods high in oligosaccharides; onions, garlic, leeks, asparagus

Proteobacteria

Contains some pathogens; often elevated in inflammation

Diets high in fat/ sugar do this

Foods associated with higher proteobacteria;

Processed meats
High-fat fried foods
High-sugar processed snacks

Verrumicrobiata

Supports gut barrier, metabolic health, glucose control

Foods that increase;

Polyphenols; pomegranate, berries, cranberries, grapes
Green tea
Red wine (very small amounts)
Prebiotic fibersinsulin rich foods (garlic, onion)
