Here’s the scoop on lactose intolerance

Farm and Dairy file photo

Lactose intolerance is the inability to break down and absorb lactose. Lactase is the body’s enzyme that helps digest lactose, which is a sugar naturally found in dairy products. Insufficient lactase will cause gastrointestinal disturbances after consuming more lactose than the body can properly digest.

Between the ages of three and five, a lot of people begin to produce less lactase, but many people continue to be able to consume dairy products without problems.

Foods for lactose intolerance

Can lactose intolerant people still consume dairy products? Yes! There are many ways for lactose intolerant people to still enjoy milk, cheese, butter, cream, yogurt, cottage cheese and ice cream in their diets.

Here are some lactose-friendly eating options:

  • Drink a small amount of milk (8 ounces) with a meal, then gradually increase the amount over days or weeks.
  • Eat lactose-free milk, cheese and yogurt, which still offer nutritional value that your body needs.
  • Eat cheeses such as mozzarella, Swiss, Cheddar, Colby and Monterey Jack that contain low amounts of lactose, so opt for these varieties.
  • Greek yogurt is low in lactose and packs in a lot of protein.
  • Mix milk with other foods, like soup, cereal and fruit. Doing this aids digestion.

There are non-dairy foods that are good sources of calcium, too, such as:

  • Milk substitutes, like soy milk, that contain added calcium and vitamin D.
  • Cereal, orange juice or other products that are fortified with calcium.
  • Canned salmon and other non-dairy foods that are rich in calcium.
