Lactose Intolerance Prevalence

Friday November 6, 2009

Lactose intolerance may not be as prevalent as was once thought, suggests a study published in the September/October 2009 issue of the journal Nutrition Today. According to the study abstract, telephone interviews were conducted with over one thousand adults from the following ethnic groups: European American (EA), African American (AA), and Hispanic American (HA). The study found prevalence rates of 12 to 13 percent, much different from the approximately 25 percent figure normally stated.

Keeping in mind that this is only one study, it does suggest that you should not jump to a quick conclusion that you are lactose-intolerant. The downside of a misdiagnosis is that you might be avoiding certain nutritious foods needlessly. On the other hand, there is often an overlap between lactose intolerance and IBS. So confusing! The bottom line is that if you suspect you are lactose intolerant, have a discussion with your doctor. They may suggest diagnostic tests for the presence of lactose intolerance, the use of a food diary, and/or an elimination diet.
