Many people become less able to digest milk products as they leave childhood behind. This is usually a gradual process but may occur suddenly in adulthood following an antibiotic regimen or other gastrointestinal problem. Symptoms of intolerance include flatulence, nausea, upset stomach, diarrhea, or gas pain following ingestion of dairy products. In some cases, symptoms may persist for days. Lactose intolerance should be diagnosed by a physician so that serious causes for these symptoms may be ruled out.
Testing is simple.
Many people who suspect they are lactose intolerant merely try a two-week dairy free diet to see if symptoms improve prior to discussing it with a doctor. Filled with hundreds of recipes , detailed instructions, and wisdom gleaned from a multitude of readers, The Encyclopedia of Country Living is so basic, thorough, and reliable it deserves a place in every country life collection.

Reader's Digest has updated its popular Back to Basics series to provide the ultimate how-to book.
