Health Prose: A One-Minute Update for Your Health Lactose Intolerance: No More Moo Juice University of Iowa Health Science Relations and Joel Weinstock, M.D. Professor of Internal Medicine Peer Review Status: Internally Peer Reviewed Cereal with milk, cottage cheese, creamy sauces, and ice creamthe milk products that are routine mealtime items for many people may cause gastrointestinal problems for others who have developed lactose intolerance. This condition results from a lack of an enzyme, lactase, in the intestines, says Dr. Joel Weinstock, professor of internal medicine at the University of Iowa College of Medicine. The lactase enzyme is necessary for digesting the sugar lactose that is found in milk and dairy products, explains Weinstock, who also is Director of the Division of Gastroenterology-Hepatology and Center for Digestive Diseases and a staff physician at UI Hospitals. "Most everyone is born with an adequate supply of the enzyme, but as people grow older, some lose part of the enzyme," he says. Scientists do not know why some people lose the enzyme and why others don't. The symptoms of the condition depend upon the severity of the intolerance. Most people who cannot tolerate lactose feel bloated and pass lots of gas when they consume too many milk products, and some may develop diarrhea, Weinstock says. The symptoms generally disappear when milk products are reduced or eliminated from the diet. Lactose intolerance is not serious and does not lead to other medical problems, he notes.

Health Information for Teens Lactose Intolerance: A Guide for Teens You probably know someone with lactose intolerance. Maybe that person is a family member, a friend, or you. Lactose intolerance is very common; in fact, as many as 70% of the world's population is lactose intolerant. It is most common among Asian Americans, African Americans, and Native Americans, but affects people of all races and ethnic backgrounds. Read on to learn more facts about lactose intolerance! What is lactose? Lactose is a natural sugar found in milk and other dairy products. Your body makes an enzyme called lactase that breaks down lactose into sugars that your body can digest and use for energy. What is lactose intolerance? If you have lactose intolerance, your body may not be able to break down all the lactose that you eat or drink. People who are lactose intolerant have problems such as nausea, stomach cramps, gas, bloating, and diarrhea after they eat or drink milk or foods that contain milk. How can I tell if I have lactose intolerance? If you have nausea, stomach cramps, gas, bloating, or diarrhea within 15 minutes to several hours after eating or drinking foods with lactose, you may have lactose intolerance.

M alabsorption of dietary lactose in the small intestine results in gastrointestinal symptoms such as abdominal pain, bloating, passage of loose, watery stools, and excessive flatus. Lactose intolerance is generally a lifelong inherited condition but can be a temporary result of an infection or other insult to the jejunal mucosa. Recognition of this prevalent condition is important, as it is easily managed by simple dietary adjustments. Accurate diagnosis of lactose intolerance can significantly relieve patient anxiety and avoid inappropriate investigation and treatment. The amount of ingested lactose required to produce symptoms is usually about 8 to 12 oz of milk.

Lactose intolerance is an inability to digest and absorb lactose (the sugar in milk) that results in gastrointestinal symptoms when milk or products containing milk are drunk or eaten. What causes lactose intolerance? Lactose is a larger sugar that is made up of two smaller sugars, glucose and galactose. In order for lactose to be absorbed from the intestine and into the body, it must first be split into glucose and galactose. The glucose and galactose then are absorbed by the cells lining the small intestine. The enzyme that splits lactose into glucose and galactose is called lactase, and it is located on the surface of the cells that line the small intestine.

People with lactose intolerance do not have enough of the enzyme lactase, which is required to digest lactose. Symptoms A person with lactose intolerance who consumes milk or other dairy products may feel abdominal pain, gas, bloating, cramps, distention and/or diarrhea. These are signs that the digestive system cannot digest or absorb lactose, or can be signs of other medical conditions. Consult your clinician for a diagnosis. Causes What causes lactose intolerance? A genetic trait causes some people to gradually make less lactase as they reach their teens or early twenties (they become increasingly lactose intolerant as they get older). Lactose deficiencies are more prevalent in certain ethnic groups, including African Americans, Asians, Jews, Mexicans, Native Americans and those of Mediterranean origin. Lactose intolerance can also occur if you have been consuming dairy foods regularly and stop for a period of time. Reintroducing these foods into your diet may result in symptoms of lactose intolerance.

The enzyme lactase is needed to digest lactose, and a few children and many adults do not produce sufficient lactase to digest the milk sugar. The condition is rare in infants. Only one-third of the population worldwide retains the ability to digest lactose into adulthood. Most adults of Asian, African, Middle Eastern, and Native American descent are lactose intolerant. In addition, half of Hispanics and about 20% of Caucasians do not produce sufficient lactase as adults. A simple test for lactose intolerance is to drink at least two 8-ounce glasses of milk on an empty stomach and note any gastrointestinal symptoms that develop in the next four hours. The test should then be repeated using several ounces of

Getting Enough Calcium WHAT IS LACTOSE? LACTOSE IS THE SUGAR found in milk. It is present in the milk of all mammals, but is not found anywhere else in nature. Manufacturers sometimes use lactose as a filler in products containing artificial sweeteners and also in some tablets. Lactose is normally broken down in the small intestine into its component sugars, glucose and galactose, under the action of an enzyme called lactase. Return to Index LACTOSE INTOLERANCE MOST MAMMALS PRODUCE the lactase enzyme until they are weaned, then stop. Humans are unique mammals because they continue to produce lactase throughout life. Most people of Anglo-Saxon origin keep producing lactase and rarely develop lactase intolerance. But, from many parts of Asia, Africa, the Middle East and some Mediterranean countries and the Australian aboriginal people don't. Many gradually produce less lactase and develop lactose intolerance. Without sufficient lactase enzyme, the lactose sugar is not digested normally in the small intestine. Instead, it passes to the large intestine where it is fermented into bacteria. This fermentation can cause excessive amounts of wind as well as bloating and pain. Some people develop diarrhoea.

78. National Food Service Management Institute lactose intolerance FACT SHEET FOR CHILD NUTRITION PROFESSIONALS Lactoseintolerance is the body s inability to produce enough of the enzyme lactase http://www.nfsmi.org/Information/Newsletters/lactoseintolerance.html

Special Needs Fact Sheets LACTOSE INTOLERANCE FACT SHEET FOR CHILD NUTRITION PROFESSIONALS INTRODUCTION Lactose, or milk sugar, is the primary carbohydrate in milk. Since milk is an important source of the calcium and other essential nutrients every child needs for growth, Child nutrition professionals should work with children diagnosed with lactose intolerance and their parents to implement strategies to improve their tolerance of dairy foods or to find alternative sources of calcium when necessary. WHAT IS LACTOSE INTOLERANCE? Lactose intolerance is the body's inability to produce enough of the enzyme lactase needed to break down lactose so that it may be absorbed in the intestinal tract. Lactase is produced in the small intestine. Infants have an abundant supply of lactase. However, in some people, lactase levels decline as they age. This decline in lactase is called lactase non-persistence. Not everyone who has declining levels of lactase has lactose intolerance symptoms. Whether or not a person has symptoms depends on the level of lactase enzyme present and the amount of lactose consumed. If the levels of lactase are not sufficient for the amount of lactose consumed, the undigested lactose travels to the colon where intestinal bacteria feed on the undigested lactose-producing gas and the gastrointestinal symptoms associated with lactose intolerance. DIETARY MODIFICATIONS FOR LACTOSE INTOLERANCE Studies have shown that most people who have low levels of lactase can consume one cup of milk with a meal, or up to two cups of milk per day, without experiencing symptoms of lactose intolerance. In fact, drinking some milk on a daily basis, even if it is a small amount, may improve tolerance to lactose. Cheese is usually tolerated because it contains little or no lactose. Only a small amount of lactose is present in the milk curd used for making cheese. Aged cheeses are made with bacteria or molds that further decrease the lactose level during the ripening process. Examples of aged cheeses are Parmesan, cheddar, gouda, and Monterey Jack.

Will I develop more l actase, i.e., the ability to digest milk, as time goes on and I drink more milk, or will I have to take Lactaid milk for the rest of my life (it's not available in some countries). Dear Alice, What are the symptoms of lactose intolerance (i.e., how long after taking a milk product will symptoms generally begin, and what are the typical symptoms), and how do they differ from irritable bowel syndrome? Dear Readers #1 and 2, Lactose intolerance is a condition in which the milk sugar lactose cannot be digested because of a partial or full deficiency of the lactase enzyme that's needed to break it down. With lactose intolerance, whatever lactose that remains undigested in the intestines attracts water, which results in gastrointestinal (GI) discomfort, bloating, gas, cramps, and diarrhea. Normal GI bacteria also ferment the undigested lactose, which exacerbates the symptoms of lactose intolerance. Symptoms usually occur with in one to two hours of ingesting a food containing lactose. Lactose intolerance is common, affecting nearly three-quarters of the world's population. Lactose intolerance is most prevalent among blacks, Asians, South Americans, and Native Americans. It's least prevalent among people of Western and Northern Europe an ancestry, particularly the Swedes and Danish.

Mac users: please note that our site is optimized for the Safari browser Food choices and health Milk allergy or lactose intolerance? Originally Published: May 02, 2003 Dear Alice, This may sound like a dumb question... But I really am unsure. What is the difference between a milk allergy and lactose intolerance? Or are they one in the same? I was in an accident when I was 14. I had emergency surgery on my liver and spleen. After about the age of 20, I have developed severe mad dashes to the restroom after eating anything dairy. But I have a lot of Sinus allergies... that seem to flair up after eating milk products. Although generally milk products do cause thickening of the mucus... I was wondering if severe congestion also goes with it? I no longer eat milk products, of course. But I recently read about a child with a milk allergy who could not breathe through his nose afterward... accompanied by severe coughing. I am now 40 and learned my lesson well... But still curious and always looking for additional info and answers!! Thanks, Kathy
