Dairy Digestion Test

The Dairy Digestion Test will help you find out if your sensitivity to dairy is caused by lactose intolerance. All you have to do is eat! (Okay, and track any discomfort you may feel.) If you aren’t sure how your digestive system will react to dairy, you should take the test at a time where you’re mostly home. If the evaluation indicates you may be lactose intolerance, you should discuss the results with your doctor.

You’ll test your reaction to dairy with breakfast and a serving of regular fat free milk.

You’ll eat the same breakfast but replace the regular fat free milk with LACTAID® Fat Free Milk.

How did you feel on Day 2 compared to Day 1? This can indicate if you’re lactose intolerant.

 

Day 1 instructions:

  • Don't eat anything after 10 PM on the evening before the test.
  • Enjoy a breakfast that doesn't include any dairy, like yogurt or cheese. You can find a list of foods that

    contain dairy here. Try eggs and whole wheat toast with jam. In addition, include a large 12 fl. oz. glass of fat free regular milk.

  • Keep track of any discomfort you experience (gas, bloating, cramping, diarrhea) and its intensity over the
    next three hours using the test checklist. Circle the number indicating its intensity. Discomfort is typically felt
    30 minutes to two hours after eating dairy.
    Here's what the checklist looks like:

  • Don't eat or drink anything after 10 PM.
