We have all heard about probiotics. We see the commercials about yogurt with probiotics or capsules containing them, etc. But are they really good for you?

Probiotics are live microorganisms (bacteria) that are similar to those found naturally in the human body and may be beneficial to your health. Some of the health concerns reported to benefit from consuming probiotics include infectious diarrhea, antibiotic-associated diarrhea, childhood eczema, irritable bowel syndrome, and even reducing the severity of cold and flu.

But the Food and Drug Administration (FDA) has not endorsed any health claims for probiotics. As with all supplements, there is no regulation by the FDA as to the ingredients or effectiveness. The labels on dietary supplements are regulated, however.

From the TV commercials and magazine ads we are told that our digestive tracts will become regulated if we eat yogurt or take supplements containing them. None of the research supports these claims as of yet.

The only research that proves benefit from probiotics is treating antibiotic-associated diarrhea. Even that research is being called into question by the most recent studies.

Instead of taking probiotics, what can you do to ensure digestive health? Eat a healthy, balanced diet and make sure you get dietary fiber. Drink plenty of fluids, especially water. Get regular exercise. And if you have problems like constipation or diarrhea, please see your health care provider.
