The article states that adults and adolescents who have been diagnosed with lactose malabsorption can tolerate at least 12 grams of lactose in a single dose. Generally, that’s one cup of milk.
There is additional straight talk about lactose intolerance on the website for the National Digestive Diseases Information Clearinghouse (NDDIC), where a section on symptoms explains that lactose intolerance can cause varying amounts of discomfort between 30 minutes and two hours after ingesting milk products.
You might be tempted to self-diagnose lactose intolerance when you are having digestive discomfort, but the NDDIC describes an easy test that can actually measure the digestion of lactose.
Called the hydrogen breath test, it involves drinking a lactose-loaded beverage and then measuring hydrogen, which goes up in the presence of undigested lactose.
The NDDIC also points out that certain processed foods contain small amounts of lactose, including bread, pancake mix, instant potatoes, chips, salad dressing and non-dairy coffee creamers.
A diet supervised by a registered dietitian or other health care professional can ensure you are getting adequate nutrients while minimizing digestive discomfort, the NDDIC says.
