Sixty Percent of Adults Can't Digest Milk Instead, people who are lactose intolerant can't digest the main sugar —lactose— found in milk. In normal humans, the enzyme that does so —lactase— stops being produced when the person is between two and five years old.

Lactose intolerance Lactose intolerance is very common in adults. It is rarely dangerous. Around 30 million American adults have some degree of lactose intolerance by age 20. 1  In Caucasians, lactose intolerance often develops in children older than age 5.  In African Americans, the problem can occur as early as age 2.

Have lactose intolerance? You can still drink milk and eat cheese Lactose intolerance is different from a milk allergy. A cow's milk allergy is triggered by the immune system, not the digestive system like in lactose intolerance. Someone with a milk allergy must avoid all milk and dairy products.

Lactose intolerance Very rarely, a baby is born with lactose intolerance. (Both parents would have to pass the gene for this type of lactose intolerance to the baby.) From birth, the baby would have severe diarrhea and be unable to tolerate the lactose in his mother's breast milk or in formula made from cow's milk.

The Healthiest Diet for Lactose Intolerance Lactose intolerance is more prevalent in adults than in children, as the body is less reliant on milk than it is during infancy, and therefore produces less lactase, the enzyme that breaks down lactose. In the past, it's been standard practice for people with the condition to avoid all dairy products.

Sixty Percent of Adults Can't Digest Milk But those allergic reactions are relatively rare, affecting an estimated 4% of adults. Milk's different. There are people who have true milk allergies that can cause deadly reactions. Instead, people who are lactose intolerant can't digest the main sugar —lactose— found in milk. In normal humans, the enzyme that does so —lactase— stops being produced when the person is between two and five years old.

Lactose Intolerance Later in Life Milk products containing lactose also provide calcium for healthy bones. Progressive development of an intolerance to lactose and decreased lactose absorption during the aging process are inevitable in most people. Reduced intake of milk and milk products containing lactose presents a special problem in older adults.

- Lactose intolerance is a deficiency in the enzyme lactase. Lactase is the enzyme that digests the milk sugar lactose. People with a lactose intolerance typically experience an upset stomach, bloating, gas, and loose stools. These are also common symptoms of a dairy allergy.

Top 30 Doctor insights on: How Can A Person With Lactose Intolerance Obtain Dietary Calcium Lactose-free milks are the same as regular milk, except for the addition of lactase. Regular milk contains the milk sugar lactose, while lactose-free milk does not. Lactase, an enzyme produced by the stomach, breaks down the milk sugar galactose so you can absorb it. People who have lactose intolerance, a lactase deficiency, have gastrointestinal symptoms when they consume dairy products containing lactose.

- People who are lactose intolerant are missing the enzyme lactase, which breaks down lactose, a sugar found in milk and dairy products. As a result, lactose-intolerant patients are unable to digest these foods, and may experience symptoms such as nausea, cramps, gas, bloating and diarrhea. Many non-dairy products contain casein (a milk derivative), listed on the ingredient labels. 2  Some specialty products made with milk substitutes (i.e., soy-, nut-or rice-based dairy products) are manufactured on equipment shared with milk. 3  Some meats may contain casein as a binder. 4  Check all labels carefully.
