In fact there are more than 400 types of “friendly” bacteria in your gastrointestinal tract. These friendly bacteria, called probiotics, promote a healthy digestive system by reducing the growth of harmful bacteria.
There is a growing public and scientific interest in probiotics. Researchers are studying whether probiotics taken as foods or supplements can help treat or prevent illness. There is encouraging evidence that probiotics may help:
- Treat diarrhea, especially following treatment with certain antibiotics
- Enhance and boost the immune system
- Promote and improve digestive health
- Prevent and treat vaginal yeast infections and urinary tract infections
- Treat irritable bowel syndrome (IBS)
- Reduce bladder cancer recurrence
- Shorten the duration of intestinal infections
- Help alleviate symptoms of lactose intolerance
- Prevent and treat inflammation following colon surgery (pouchitis)
- Prevent eczema in children
- Reduce cholesterol levels
- Play a role in reducing the development of allergy in children
- Decrease Helicobacter pylori colonization of the stomach
- Prevent cavities and ease gum disease (Only a small number of studies have shown this)
Some researchers believe probiotics may improve general health. Each type of friendly bacteria has a specific health benefit to the body. With over 400 different types of probiotics identified, researchers are just starting to uncover the health roles and benefits of each.
Food Sources
Currently, foods that contain probiotics are primarily dairy products but sources include:- Yogurt with active culture (Pay close attention to the expiration date because these live bacterial cultures can diminish with time)
- some soft cheeses
- Fermented milk such as sweet acidophilus milk
- Kefir
- miso
- some juices and soy drinks
- sauerkraut
- many pickles
Probiotics are affected by prebiotic food. Prebiotic food does not generally contain bacteria but promotes the growth and proliferation of beneficial bacteria in the intestinal tract which enhances the effect of probiotic bacteria. Prebiotics have also been shown to increase the absorption of certain minerals (such as calcium and magnesium) and may reduce the risk factors involved in colorectal diseases.
Prebiotic foods include Jerusalem and regular artichokes, oats, honey, many fruits (in particular, bananas), goat’s milk and human breast milk which may explain the enormous benefits to a newborn.
Probiotic Supplements
Probiotic supplements are available in a variety of forms, such as freeze dried powder, capsules, wafers and liquids. A good probiotic will contain at least 10 billion live bacteria and should be from one or more of the Lactobacillus family in a single dose.
