Two pounds of bacteria in your gut!
The human intestinal tract is home to more than 400 species of bacteria weighing a total of ~2 pounds. Concentration of bacteria increases dramatically from the stomach to the small intestine, to the colon. Bacteria comprise 1/3 dry-weight of feces.
Bacterial flora consist of aerobic and anaerobic species. In a healthy large bowel, anaerobes outnumber aerobic bacteria by up to 1000 to 1.
- Anaerobic flora is dominated by Bacteroides spp., bifidobacteria, propionibacteria and clostridia
- Among aerobic bacterial flora, the Enterobacteria Escherichia coli, a facultative anaerobe (able to adapt to produce energy from glucose with or without oxygen) of the enterobacteriaceae family and Enterococci (another facultative anaerobe) predominate. Note that most strains of E. Coli benefit the gut by producing vitamin K2 and keeping a check on pathogenic bacteria. It is only some of its serotypes (variations) that are pathogenic, and which can cause intestinal diseases E.g. food poisoning, UTIs and neonatal meningitis.
Appropriately balanced gut flora needed for healthy immune system
Studies are demonstrating the ability of the gut flora and oral probiotics to influence systemic inflammation, oxidative stress, glycemic control, tissue lipid content and even moods. At least 60% of our immune system is located in our digestive system!
“Do you have a good “Gut feeling?” can be taken literally
Since most SEROTONIN (the “feel-good”chemical) is produced in the gut.
A healthy balance of gut flora is generally considered to be 15% “unfriendly” bacteria vs. 85% “friendly”bacteria. This ratio prevents the over colonization of disease causing micro-organisms (E.g. E. coliand Salmonella) and competes with and prevents the overgrowth of yeast and fungi.
- Many lifestyle and environmental factors can upset this balance by harming the “friendlies”- such as:
• Poor diet - excess sugar/fructose, processed foods/refined grains, herbicides/insecticides/pesticides;
• Chlorinated/Fluoridated drinking and showering water
• Too much alcohol
• Pollution - industrial/household chemicals
• Medication- especially antibiotics/anti-bacterial soaps (which destroy all bacteria - good and bad), contraceptive pill, and antacids
• Geographic location
• Socioeconomic circumstances
- Symptoms that your “friendly bacteria” are “Losing the Battle”, include:
• Cravings for sugar and refined carb foods - the “unfriendlies”are insisting you feed them!
• Gas and bloating / Nausea / Headaches
• Constipation or diarrhea
- A large part of the influence of the "bad" bacteria is on the intestinal lining (mucosal barrier). The lining is over 300 square meters (about the size of a tennis court.)
- For optimum intestinal flora balance, the beneficial LACTIC ACID bacteria, such as the gram-positive Lactobacilli and Bifidobacteria, should predominate (Bifidobacteria account for ~ 90% of the total colonic beneficial microflora). Presenting a barrier to invading organisms, they break down food carbohydrates to produce acids, such as lactic acid (break-down product of lactose). The most common of these lactic acid bacteria are:
• LACTOacido bacillus Inhabits both the small and large intestines
• Bifidobacteria bifidum. More prevalent in the large intestine, also the dominant species of the intestinal tract of breast-fed infants.
Which bacteria reside in the gut?
Upper GI Tract
Esophagus - contains only the bacteria swallowed with saliva and food
Contains mainly acid-tolerant LACTOBACILLI
Stomach of ~50% of U.S. population have been colonized by the pathogenic bacteria Helicobacter Pylori. Responsible for gastric ulcers and also most likely gastric and duodenal cancer
The upper small intestine. Contains relatively sparse GRAM-POSITIVE flora, consisting mainly of LACTOBACILLI and Enterococcus faecalis.This region has about 105 - 107 bacteria per ml of fluid.
The lower small intestine. Contains 108 bacteria /mlwith additional species including coliforms and Bacteroides
Large Intestine (Colon)
Colon contains bacteria similar to fecal bacteria
Bacteriallevels reach 1011/ml feces

"The medical kit of the future"
General electrotherapy health benefits. Used systemically and/or locally at specific problem areas of the body, its effective application has many benefits:
|Detoxification||Wellness / Healthy aging||Pain relief|
|Relief from insomnia||Immune system restoral||Anti-Inflammatory|
|Maximizes cellular energy production||Accelerated tissue /bone
|Muscle relaxation / rehabilitation||Increased blood oxygen
There are several reasonably affordable electrotherapy devices available for personal use. The following electrotherapies are those that have received a significant amount of positive feedback:
|Pulsed Electromagnetic Field (PEMF) therapy|
|Near Infrared (NIR) class 4 laser therapy|
Cranial Electrotherapy Stimulation (CES) applies specific frequency patterns to the head area, with the following benefits:
|Balances neurotransmitters||Relieves pain||Treats depression|
|Substance abuse withdrawal||Relieves insomnia||Relieve stress / anxiety|
