The Power of Yogurt

Whenever I prescribe antibiotics, I usually recommend eating yogurt. I have also recommended yogurt to patients with lactose intolerance and irritable bowel syndrome. The reason is Probiotics.

Probiotics are microorganisms (bacteria and a few yeast types) that are similar to the beneficial organisms in our digestive system (the gut has about 400 types of probiotic organisms). They are also called "good bacteria." They promote a healthy digestive tract and reduces the number of harmful bacteria. The most common probiotics are Lactobacillus and Bifidobacterium. Probiotics are found in yogurt, fermented and unfermented milk, miso, soy drinks, fermented foods (pickled vegetables, kimchi, sauerkraut, etc...), and dietary supplements.

The GI tract needs to maintain a healthy balance of good bacteria. When antibiotics are taken, the good bacteria may also be killed, changing the balance and leading to gas, cramping, or diarrhea (and potentially Clostridium difficile colitis). Studies have shown there is up to a 50% reduction in antibiotic associated diarrhea with the use of probiotics.

Other potential benefits by taking probiotics include:
1. Managing lactose intolerance
2. Suppress or reduce bad organisms associated with traveler's diarrhea, infectious diarrhea, irritable bowel syndrome, vaginal infections, Helicobacter pylori gastritis, inflammatory bowel disease, and tooth decay
3. Prevent colon cancer...studies pending
4. Possibly reducing blood pressure and cholesterol
5. Improving immune function
6. Managing eczema
7. Improving irritable bowel syndrome symptoms
8. Reducing inflammation associated with colitis

Probiotics are considered safe. Dietary supplements (capsules, powder, liquid extracts) are not regulated by the FDA so consult your primary physician for more information.

Yogurt is a good source of probiotics. Make sure the label states "active culture." Probiotics can potentially help with overall health. Studies are ongoing.

When taking antibiotics though, consider consuming two servings of yogurt a day to reduce antibiotic associated complications like diarrhea, gas, cramping, and nausea.

As always, talk to your health care professional before you start any supplements.
