Yes, lactose-free low-fat or fat-free milk and dairy products are still good sources of protein and calcium. In fact, lactose-free dairy products provide the same amount of calcium as do those containing lactose, which is the major sugar found in milk.
Lactose intolerance is a problem caused by the digestive system. It occurs when there is a shortage of the enzyme lactase, which is produced by the cells that line the small intestine. These cells break down milk sugar into simpler sugars that the body uses. A deficiency of these cells can lead to gas, cramps, and bloating. This condition is often self-diagnosed and blamed for any discomfort following the ingestion of dairy foods, but only doctors can perform tests to diagnose true lactose intolerance.
Many people who are lactose intolerant can actually enjoy dairy products in small amounts or with other foods. It may be that consuming a moderate to large amount of dairy on an empty stomach will produce symptoms, while small amounts of South Beach Diet–friendly low-fat or fat-free milk, yogurt, or hard cheeses (consumed with or without other food) may be well tolerated. Soy milk and soy cheeses are also fine substitutions when they do not contain added sugars.
