People have different degrees of lactose intolerance. It is advisable that you consult with a physician to confirm the diagnosis and to determine your personal degree of intolerance. Many people can tolerate some dairy, depending on its form.
Try cheeses.
Much of the lactose is removed during processing. Cheeses that have aged are also lower in lactose. Swiss, Cheddar, Colby and Parmesan are good choices.
Try ice cream or frozen yogurt.
The solid nature and fat content tend to slow the digestion process, making the lactose easier to tolerate. (Ice cream is a high-calorie/high-fat food, so treat yourself once in a while to this dairy product.)
Try yogurt.
Choose yogurt that specifies "active or live cultures" on the label. Active cultures help to digest some of the lactose, making it easier to tolerate.
Buy lactose-reduced milk. This milk has about 70 percent less lactose than regular milk. Look for other lactose-reduced products in the dairy case.
Drink small quantities of milk with other foods.
When milk is consumed with food, the digestion process is slowed and symptoms of lactose intolerance are less likely or less severe.
