Lactose-Free Diet

Lactose is the sugar that is found naturally in milk and milk products, as well as foods with ingredients such as milk or whey. In order for the body to use lactose, it has to break it down using an enzyme called lactase. Lactose intolerance is a condition that occurs when a person does not produce enough lactase to break down the lactose in food.

Symptoms of lactose intolerance include:

  • Abdominal cramping
  • Bloating
  • Gas
  • Diarrhea

These symptoms may occur shortly after eating foods that contain lactose, but sometimes will not occur until hours later. This is because people vary in the amount of lactose they can tolerate.

When milk products are eliminated from the diet because of lactose intolerance, an important source of calcium and other vitamins and minerals is eliminated. Because of this, your child will need to get calcium from other sources, or may need to take a calcium supplement. Be sure to consult with your child's doctor or dietitian before giving any supplements. The amount of calcium a child needs will depend on their size and age.

Avoiding Lactose

There are many different words that are used to describe the different forms that lactose may come in. Read food labels, and stay away from foods with any of the following ingredients:

  • Milk
  • Skim milk powder
  • Skim milk solids
  • Lactose
  • Whey
  • Caseinate
  • Curd

The following ingredients are okay to use:

  • Lactase
  • Lactalbumin
  • Lactylate
  • Calcium compounds

Reading food/nutrition labels is a very important habit to get into when looking for foods that do not contain lactose. Lactose can come in many "hidden" forms, and even products that do not appear to have milk included, may in fact have a milk product as an ingredient.
