Probiotik Definition

• In general, Probiotics are live micro-organisms (in most cases, bacteria) which are found identical to helpful micro-organisms found in the human intestine.

• According to the currently adopted definition by Food and Agriculture Organization /World Health Organization, probiotics are: ‘Live microorganisms which when administered in adequate amounts confer a health benefit on the host’.

• Probiotics are available in foods and dietary supplements (for example, capsules, tablets, and powders) and in some other forms as well.

• Examples of foods containing probiotics are yogurt, fermented and unfermented milk, miso, tempeh, and some juices and soy beverages

Types of Probiotic Bacteria

* Good Bacteria Examples Bifidobacterium,

Eubacterium, and Lactobacillus (Lactic acid bacteria).

* Bad or Pathogenic Bacteria Examples Clostridium, Salmonella,

Shigella, and Candida.

A few fermented pruducts containg lactic acid and having

probiotic effects :• Kefir• Yoghurt• Sauerkraut• Kimchi• Kombucha

Characteristics of good bacteria that can be used as probiotic agent, including:

1. Having antimicrobial activities2. Resistant to digestion tract selection

system3. Having anti carcinogenic activities4. Able to colonize in the intestinal tract 5. Able to improve intestinal absorption

Main functions of probiotic food :

• Maintain a balance of intestinal bacteria

• Reduce blood cholesterol level • Prevent the formation of cancer

cells• Helps the digestion of lactose

(sugar in milk)

Benefits of Probiotics

1. Maintaining a balance between pathogenic bacteria and good bacteria in the intestine

2. Help clean up the tract and produce vitamins

3. Help liver function in detoxifying 4. Prevent diarrhea, constipation and

allergies5. Reduce the possibility of allergic

reactions

6. Probiotik overcomes human indigestion problem

7. Prevents IBS ( Irritable bowel syndrome)

8. Increase the system’s immunity

The beneficial bacteria in the alimentary tract,

including : • Lactobacilus acidophilus• Lactobaciluus casei• Bifidobacterium bifidum• Bifidobacterium langum• Saccharomyces boulardii

•

Lactobacillus caseiLactobacillus bulgaricus

Bifidobacterium

Examples of pathogenic bacteria in the alimentary tract:

1. Staphylococcus aureus2. Salmonella : causes enteric fever and

gastroentritis 3. Shigella : causes shigellosis (Basher

dysentery)4. Vibrio cholerae 5. Clostridium botulinum6. Pseudomonas cocovenenans
