People who are lactose intolerant may experience symptoms of gas, cramping and bloating as a result of a lack of sufficient quantities of the enzyme lactase in the intestines that can down lactose, the sugar found in dairy items.
Some people with lactose intolerance can be symptom free when they eat other sources of dairy such as yogurt and aged cheese or milk in smaller quantities up to 4 ounces at a time. Include dairy products with active and live cultures, aged cheese, yogurt, lactose free dairy products such as milk, cottage cheese and ice cream, and include in recipes with other foods.
Lactase in pill form (Lactaid) can also be taken to improve your body’s ability to tolerate dairy.
Dairy foods are great sources of nutrition including calcium, vitamin D, protein, potassium, magnesium, niacin, vitamin B12, riboflavin, and phosphorus. When you take dairy foods off your plate, it can be very harmful to bone health.
You may want to try incorporating sources of dairy back into your teenager’s diet to provide sufficient nutrition in a way that is best tolerated.
