Lactose Intolerance

Learn How and Why to Enjoy Dairy Even If You’re Lactose Intolerant

Are you lactose intolerant or do you know someone who is? Being lactose intolerant doesn’t mean you have to give up dairy – seriously! There are a variety of ways to enjoy milk, cheese and yogurt, and get the nutrients – like protein and calcium – that come with them. Get the facts before giving up dairy.

Definition, Diagnosis and Diet

Lactose intolerance often is misunderstood and is commonly confused with a milk allergy. It’s estimated that 10 percent of Americans are lactose intolerant, but because this condition is often self-diagnosed, the true prevalence is likely lower. Widespread awareness of the definition of lactose intolerance could significantly reduce this estimate. Inaccurate self-diagnosis or misinformation may cause people to unnecessarily eliminate dairy from their diet and miss out on its key nutrients.

Let’s break down the truth about lactose intolerance with a definition. Lactose is the natural sugar found in milk. Lactose intolerance is defined as a gastrointestinal disturbance following the consumption of an amount of lactose greater than can be digested and absorbed by the body. It is not a milk allergy. Symptoms of lactose intolerance range from mild to severe and occur about 30 minutes to two hours after eating or drinking foods containing lactose. These symptoms include nausea, cramps, bloating, gas and diarrhea.

Diagnosis of lactose intolerance is difficult based on symptoms alone because other conditions, such as irritable bowel syndrome (IBS) and celiac disease, cause similar symptoms. Adults tend to have lactose intolerance more than children, since our bodies may make less of the enzyme needed to digest lactose as we get older. If you suspect you or your child has lactose intolerance, it is best to talk with your doctor and be tested. Your doctor can further explain the lactose intolerant definition to your satisfaction.


Even if you are lactose intolerant, this doesn’t mean you need to abstain from dairy foods. Luckily, there are a host of solutions to keep dairy foods in the diet, so you still receive the associated health benefits and enjoy their great taste. A cup of milk contains about 12 grams of lactose. Lactose-free milk is one of your best options — it’s real milk, just with the lactose removed! In fact, people like the taste of lactose-free milk better than some of the non-dairy alternatives.1 Some dairy foods also are naturally lower in lactose:

  • A half cup of low-fat cottage cheese only contains 3 grams of lactose while cheddar, Swiss and mozzarella cheeses contain less than 1 gram.
  • Yogurt contains about 13 grams of lactose per serving, but its live and active cultures help digest the lactose for you, meaning many individuals with lactose intolerance are able to enjoy yogurt without discomfort.
  • A serving of Greek-style yogurt has 4 grams of lactose.
  • There’s even lactose-free ice cream!

You can gather from the lactose intolerance definition that it is possible to enjoy dairy products without discomfort if they don’t contain the natural milk sugar. They are labeled as lactose-free products. The absence of lactose is the only difference between lactose-free products and regular dairy products – the taste is often the same. Look for lactose free products in the dairy section at your favorite grocery store. Be sure the products are clearly marked as lactose-free.

Because tolerance for lactose varies from person to person, lactose intolerance is a highly individualized condition. Talk with your doctor or a registered dietitian to better understand the lactose intolerant definition as it might apply to you and learn about a management approach that best suits you or your child.

Strategies to Enjoy Dairy Foods

The lactose intolerant definition shows that the condition is the result of a body’s intolerance for high levels of lactose, however, levels of lactose intolerance vary. Some foods are more easily tolerated by the body and would be a good choice for many individuals. We suggest these tips to gradually bring dairy back into the diet:

Sip It. Start with a small amount of milk daily and increase slowly over several days or weeks to tolerance.

Stir It. Mix milk with other foods, such as smoothies, soups or sauces, or pair it with meals. This helps give your body more time to digest it.

Slice It. Top sandwiches or crackers with natural cheeses such as Cheddar, Colby, Monterey Jack, Mozzarella and Swiss. These cheeses are low in lactose.

Shred It. Shred your favorite natural cheese onto soups, pastas and salads. It’s an easy way to incorporate a serving of dairy that is low in lactose.

Spoon It. Enjoy easy-to-digest yogurt. The live and active cultures in yogurt help to digest lactose.

Keep these tips in mind for recipes that include dairy. Make them lactose intolerance friendly recipes by using smaller quantities of the dairy ingredients than is listed or by substituting with lactose free products. Some recipes include suggested alternatives to dairy ingredients, for readers who need lactose intolerance recipes, or show how to modify dairy amounts and still achieve the same tastes. Your doctor or dietitian might provide recipes for lactose intolerance you can try; with some creative experimenting, they can taste like the original versions.
