Get to Know 'Friendly Bacteria'
Charles Phan, M.D., Gastroenterologist
Probiotics are "friendly" types of bacteria found in some foods, such as yogurt, that may assist with digestion and help keep you well.
When you hear the word bacteria, you may think of a condition such as strep throat and the need for antibiotics. It's true that certain kinds of bacteria are bad for the body. But there are good kinds of bacteria, as well, known as probiotics.
What Are Probiotics?
Probiotics are "friendly" types of bacteria found in some foods, such as yogurt, that may assist with digestion and help keep you well. Meaning "for life," these living organisms are so tiny that they can only be seen under a microscope.
Probiotic foods have been popular in Europe and Asia for years. There is also growing interest in probiotics and health benefits here in the United States. Mounting research suggests friendly bacteria may improve general wellness and help lessen the effects of diarrhea, vaginal yeast infections, urinary tract infections, irritable bowel syndrome, intestinal infections and eczema.
"Probiotics can be found in or added to some everyday foods such as yogurt, cheese, milk, juices and even cereal," says Charles Phan, M.D., a gastroenterologist on staff at Methodist Sugar Land Hospital.
Check Labels for Probiotics
Americans' spending on probiotic supplements nearly tripled from 1994 to 2003. Just last year, more than 200 new probiotic products hit grocery and pharmacy shelves, compared to just 34 in 2005.
"There is no daily recommended intake of probiotics needed to be healthy," Dr. Phan says. "But these microorganisms may provide some health benefits, such as helping with digestion and protection against harmful bacteria."
On your next grocery store visit, you may notice more food packaging promoting healthy bacteria or probiotic content. If you're thinking about using a probiotic product as complementary and alternative medicine, ask your health care provider first. Then, check labels for these words and phrases:
- Lactobacillus and Bifidobacterium are two common groups of healthy bacteria.
- Lactobacillus acidophilus and Bifidobacterium bifidus are different species within the two common groups.
- "Live and active cultures." The "Live & Active Cultures" seal from the National Yogurt Association ensures a minimum of 100 million live cultures per gram.
Keep in mind that over-the-counter supplements are not closely regulated and may not deliver what they promise. You should always talk to your health care provider before taking any supplements to avoid side effects and potential interactions with any medications that you are taking.
