Friends Forever Millions of microorganisms, including bacteria, yeasts, fungus and other organisms exist in and on our bodies beginning at birth. Most of these are harmless or beneficial and live with humans in symbiosis, a dependent relationship which benefits both parties. We provide them with food they need and in turn they support the immune system, digestive system, and produce some vitamins.

Have you heard of “probiotics” Have you heard of “probiotics”? You may have been reading about supplementary bacteria, or yogurt culture. It may have been touted as a treatment for side effects of antibiotics. Probiotics are the beneficial bacteria that live in our bodies and are also found in fermented foods Antibiotics and other environmental factors can deplete or alter the balance of these helpful organisms

Native Fauna in the GI The large intestine is populated by millions of bacteria that assist in the digestive process These help to Break down undigested fibers Produce some vitamins Protect against pathogenic organisms

Digestion and Absorption When digested food moves into the large intestine from the small intestine, most of the nutrients have already been digested and absorbed Organisms in the colon help to further break down cellulose and other fibers for absorption through the lining of the colon

Vitamin Production These microorganisms produce: The B vitamins Thiamine, Riboflavin and Biotin and B-12 Vitamin K These nutrients are absorbed in the colon along with some water, sodium, potassium, chloride, and some of the Vitamin K The large intestine does not absorb Vitamin B-12

Immunity Healthy populations of beneficial bacteria in the gut inhibit overgrowth of pathogenic, or harmful, organisms by competing for food and space. This protects the body from infection.

Dysbiosis An imbalance in the native micro-organisms in the GI Symptoms may be both local and systemic Can cause diarrhea, constipation, gas, bloating, cramping, indigestion, vaginal yeast infections, thrush, weakened immune system, headaches, joint pain, fatigue

Causes of Dysbiosis Chlorinated water, pollution, food additives, alcohol Antibiotics, steroid medications, overuse of laxatives, diarrhea These factors can reduce or destroy the populations of beneficial bacteria in the GI and should be reduced and avoided when you are correcting an imbalance, taking antibiotics, or simply to maintain healthy digestion.

Antibiotics Broad spectrum antibiotics, which are frequently used to treat otitis media and sinusitis, affect all strains of bacteria throughout the body without discretion. In this way the infection may be cured but the body is opened up to other sorts of infection due to the lack of beneficial bacteria. Candidiasis is such a common reaction that many patients receive antifungal medication along with antibiotics as a precautionary measure.

Supporting Healthy Gut Flora Diet and lifestyle can support the populations of healthy organisms The previously listed causes of dysbiosis should be avoided Fermented foods containing live cultures should be a regular part of the diet A diet high in soluble fiber, which feeds the helpful bacteria Probiotic supplements come in tablet, capsule, liquid, and powder forms

Acidophilus and other Probiotics The term probiotics most often refers to supplements containing presumably live bacteria that support healthy populations of bacteria or yeasts in the body. Most contain strains of Lactobacillus and Bifidobacterium similar to native strains found in the gut Most supplements contain both types of strains Transient strains pass through the system and do not re-establish colonies. They are helpful for acute and temporary conditions Resident strains are commonly found in and remain in the body Fermented foods like yogurt, kefir, kombucha, and sauerkraut also supply some of the same organisms

Prebiotics Fibers and other substances not digested in the small intestine that feed the good bacteria in the colon Fructoligosaccharides (or FOS) is the most popular and is included in some probiotic supplements and also sold separately inulin, an insoluble fiber butyrate (from the digestion of fiber) L-glutamine, an amino acid

Beginning at birth our bodies are populated by millions of microorganisms that support and protect the processes of the body. It is important to keep these in balance throughout our lifetimes to maintain healthy digestion and avoid disease
