Lactose intolerance is the inability to digest lactose, found in animal milk (including human milk, which, in fact, has about twice has much lactose as cow's milk). An enzyme called lactase is required to digest lactose. When this enzyme is missing, the following symptoms may occur: abdominal cramps, diarrhea, gas, a feeling of bloatedness. Symptoms may occur within an hour, or up to several days later. The intensity of symptoms varies widely. DIAGNOSIS Lactose intolerance can be self-diagnosed by eliminating milk and dairy products from your diet for two weeks, then reintroducing milk (a glass or two), and seeing what happens. Your doctor can administer a couple of tests to confirm lactose intolerance (basically involves drinking a sweet drink containing a lot of lactose on an empty stomach and monitoring blood levels of glucose -- no rise in glucose means the lactose is not being absorbed; the other involves checking breath levels of hydrogen). TREATMENT If you are diagnosed with lactose intolerance, you have a variety of options. Lactase is available by prescription (Lactaid), and can be added to milk (drops) or taken with food containing dairy products (tablets). Some people may have adverse reactions to this medication, however (in tablet form -- the reaction is believed to be allergic. Drops seem to be ok.). Lactose reduced milk and cheeses are available in some areas. Aged cheeses, yogurt and sour cream may be tolerable (most of the lactose has already been converted). You can find your level of lactose tolerance by either cutting out dairy products entirely and slowing working them back into your diet, or you can slowly eliminate them until you stop having difficulties. Tables indicating lactose content for milk and milk products are available. Some believe that lactose intolerance is, in fact, the human (and mammalian) norm, rather than an aberration, citing in support statistics that indicate most of the world's population is lactose intolerant (Europeans and those of European descent being the exceptions), and the tendency to lactose intolerance with increased age. MILK ALLERGY Milk allergy, on the other hand, involves an allergic reaction to one or more of the proteins in milk (casein, lactalbumin, lactoglobulins). An allergic reaction to milk may include: eczema, rash, mucous buildup, wheezing, Asthma, rhinitis, pneumonia, anaphylaxis. The type and severity of symptoms varies widely. Because a true milk allergy may involve mast cells in the mouth and throat, it is possible to have an allergic reaction to milk or milk products before they are digested. It is possible to be both lactose intolerant AND allergic to milk. DIAGNOSIS The bad news is, diagnostic tests for milk allergy -- for food allergy in general -- are hit or miss. One source I have claims that a negative is accurate, but false positives are common. Another states that the extracts used in allergy tests tend to lose potency quickly so you might test negative on a test and STILL be allergic. Elimination diets are the best test you have available to you. If you suspect milk allergy, eliminate milk and milk products for two or more weeks, and see what happens. If you can convince your physician to conduct a double-blind test on you, you may be able to confirm the diagnosis. TREATMENT The worse news is, no cure is available -- avoidance, and symptom control via antihistamines, etc. are the best you can do. (For now, at least, this is true of all food allergy, at least according to the conservative medical community -- but research is ongoing. I have a reference to a study by the National Jewish Center for Immunology and Respiratory Medicine in Denver which claims successful desensitization to peanuts in people who had a life history of allergic reaction to them. There's a dim hope, at least.) [The National Jewish Center for Immunology and Respiratory Medicine in Denver has prepared a report about successful desensitization to peanuts in patients with a life history of allergic reaction to them. The address for that group is: National Jewish Center for Immunology and Respiratory Medicine, Public Affairs Department, 1400 Jackson Street, Denver, CO 80206 303-398-1079, 800-222-LUNG (5864)] Lactose intolerance is the inability to break down the sugar in milk, lactose. There are varying levels of lactose intolerance, based upon how much of the enzyme "Lactase" your body has. The more it has, the better the ability of your body to break down the sugar, and the more tolerance you have. Since cow milk is not a natural thing for humans to drink (nor any milk past age 2), it makes sense that people will develop primary lactose intolerance over their life time and it is not uncommon for adults to develop the symptoms of lactose intolerance which include but are not limited to; diarrhea, stomach cramps, bloating, gas and nausia. If a young child has any of these symptoms, contact their doctor, as it is possible to be born lacking lactase.

Is Lactose intolerance and lactose reflex the same?

Is lactose intolerance and lactose reflex the same thing?


Are Food allergy and food intolerance synonymous terms?

Food allergy and food intolerance are not the same thing. Food allergy means that your immune system attacks the food because it is mistaken for an invading organism. Whereas, food intolerance (typically, lactose intolerance) is a difficulty in digesting that type of food due to insufficient secretiion of digestive enzymes (lactase, in the case of lactose intolerance).


Can cows be lactose intolerant?

Yes. Lactose intolerance is a phenomena of the digestive system. Just because you have milk in the mammeries has no bearing on what happens to milk in the intestines. The same argument goes for lactose intolerant (human) mothers.


Is it true that food allergies and food intolerances are the same thing?

No. A food intolerance just means that the body does not digest it well. (like celliac disease, and lactose intolerance) An allergy is an immune reaction against the food.


What are the effects of not treating lactose intolerance?

Lactose intolerance is not the same as an allergy. An allergy means that your body reacts to milk or other dairy produce and creates antibodies. Allergies can be very dangerous if your body overreacts. Lactose intolerance means that you are not able to digest lactose since you don't produce enough of the enzyme lactase. This means that lactose goes through your system until it reaches the large intestine. Here it will find lots of bacteria who are just waiting for a meal of milk sugar. They will digest the lactose and produce byproducts of hydrogen and lactic acid and other acids. The hydrogen (CO2 and methane too) will cause bloating and other uncomfortable symptoms. There is less lactose in cheese and yoghurt. When milk curdles during processing, the lactose goes in the liquid portion. The bad news is that this whey is used as a filler in almost all processed/produced goods. Look for whey and other milk products on the label. The problem with cutting out all dairy is providing yourself with enough calcium in your diet so that you don't have other problems. Have a look at the page links, listed under Related Links. These will suggest foods which have calcium and low lactose content. I avoided lactose for quite a while - just a little milk in coffee - and then reintroduced milk products. I found that I was more tolerant of them.


Is skim milk easier to digest if latose intolerant?

Skim milk has almost the same amount of lactose as full cream milk, so in terms of lactose intolerance it should be just as bad. Many people are helped by taking a digestive aid called Lactaid (or other similar products). They help with the digestion of the lactose.


Does skim milk have less lactose than whole milk?

Lactose amounts are the same regardless of fat content. Lactose is not present in milk fat.


My baby can drink milk based formula but when given regular milk she breaks out in hives where it touched the skin what is in liquid milk that is not in powder milk?

You have your infant checked for a condition known as 'Lactose Intolerant; You are describing a symptom of lactose intolerance. Cheeses (or any other standard dairy product) would produce the same results if this is the case. A lot of people are intolerant of lactose, casein and casomorphins found in milk.


Do lactose intolerant people get the same amount of Calcium from drinking milk as do non lactose intolerant people?

lactose free milk has the same calcium content as regular milk, barring additives


What causes milk allergies?

A milk allergy is caused by a protein specifically found in cow's milk. It is not the same as being lactose intolerant because that is an inability to digest a sugar found in cow's milk. See the related link for more information.

What is the difference between lactose and galactose?

galactose and lactose is the same galactose is found in the milk of mammals and even lactose is present in the milk of mammals


Does lactose free milk have sugar?

Yes, lactose-free milk contains sugar. The difference between regular milk and lactose-free milk is the type of sugar they contain. Regular milk contains sugar in the form of lactose. Lactose-free milk contains an enzyme that breaks lactose into more digestible sugars. Otherwise, the amount of sugar in both is the same.


Where can lactose-reduced milk be obtained?

Lactose-reduced milk and other products are also available in stores. The milk contains the same nutrients as regular milk.


Could you drink goats milk if your allergic to milk?

Yes. People who are allergic to cows' milk (deemed as "regular" milk) are allergic to lactose. These same people are lactose-intolerant. Since goats' milk does not contain lactose, you could drink it.


Is being lactose intolerant the same as being allergic to lactose?

No. Lactose intolerance is when you lack (or are deficient in) the enzyme lactase which breaks down the sugar found in milk (lactose). In this case drinking milk will cause bloating, gassiness, and diarrhea. If you take the enzymes (often sold as lactaid) along with the dairy then you often can lessen of avoid the symptoms. It is bothersome but generally not dangerous. People who are allergic to milk, usually the proteins - not the lactose, have an immune mediated inflammatory response to drinking milk. It can cause abdominal pain, diarrhea, eczema and even wheezing and hives. People who are allergic to milk cannot safely drink milk


Does lactose free milk curdle?

Yes. The lactose is generally replaced by fructose which is still a sugar. See 'Why does milk curdle?' - same reasons.


Why does lactose-free milk turn up as positive on a glucose strip?

lactose and glucose are not the same! milk contains sugar, and sugar (starch-->glucose) is glucose, so if the milk is lactose free, it still contains glucose and proteins...


Is lactose-free the same as casein-free?

No, lactose is milk sugar, and casein is milk protein. A food product can contain one without the other.


Can an unborn child be lactose intolerant?

Your body naturally filters out lactose but there is another bacteria that cannot be filtered out that is found in milk. and some children are allergic to it and not lactose. can you eat cheese? Cheese and milk have the same lactose but not the same bacteria potency. my daughter was breast fed and if I drank milk she got ill, there is no way she is lactose intolerant, she can eat cheeses and other dairy products. If it had been the lactose the breasts would have eliminated it. It would not have made her sick. She still can not drink milk from a jug. She can have milk that does not require refridgeration. The same thing would apply to an unborn child I would imagine, just think of your body as a filtration system.


Lactose intolerance?

DefinitionLactose intolerance is the inability to digest lactose (a type of sugar found in milk and other dairy products).Alternative NamesLactase deficiency; Milk intolerance; Disaccharidase deficiency; Dairy product intoleranceCauses, incidence, and risk factorsLactose intolerance happens when the small intestine does not make enough of the enzyme lactase. Babies' bodies make this enzyme so they can digest milk, including breast milk. Before humans became dairy farmers, most people did not continue to drink milk, so their bodies did not make lactase after early childhood.Lactose intolerance is more common in Asian, African, African-American, Native American, and Mediterranean populations than it is among northern and western Europeans.Lactose intolerance can begin at different times in life. In Caucasians, it usually starts to affect children older than age 5. In African-Americans, lactose intolerance often occurs as early as age 2.Lactose intolerance is very common in adults and is not dangerous. Approximately 30 million American adults have some amount of lactose intolerance by age 20.Lactose intolerance is sometimes seen in premature babies. Children who were born at full term generally do not show signs of lactose intolerance until they are at least 3 years old.Not having enough lactase (lactase deficiency) may also occur as a result of intestinal diseases such as celiac sprue and gastroenteritis, or after bowel surgery. Temporary lactase deficiency can result from viral and bacterial infections, especially in children, when the cells lining the intestine are injured.SymptomsAbdominal bloatingAbdominal crampsDiarrheaFloating stoolsFoul-smelling stoolsGas (flatulence)MalnutritionNauseaSlow growthWeight lossSymptoms often occur after you eat or drink milk products, and are often relieved by not eating or drinking milk products. Large doses of milk products may cause worse symptoms.Signs and testsEnteroscopyLactose-hydrogen breath testLactose tolerance testTest for stool-reducing substancesTreatmentRemoving milk products from the diet usually improves the symptoms. However, not having milk in the diet can lead to a shortage of calcium, vitamin D, riboflavin, and protein. Add other sources of calcium to the diet if you remove milk products.Most people with low lactase levels can tolerate 2 - 4 ounces of milk at one time (up to one-half cup). Larger (8 oz.) servings may cause problems for people with some amount of milk intolerance.These milk products may be easier to digest:Buttermilk and cheeses (they have less lactose than milk)Fermented milk products, such as yogurtGoat's milk (but drink it with meals, and make sure it is supplemented with essential amino acids and vitamins if you give it to children)Ice cream, milkshakes, and aged or hard cheesesLactose-free milk and milk productsLactase-treated cow's milk for older children and adultsSoy formulas for infants younger than 2 yearsSoy or rice milk for toddlersYou can add lactase enzymes to regular milk or take them in capsule or chewable tablet form.You may need to find new ways to get calcium into your diet (you need 1,200 - 1,500 mg of calcium each day):Take calcium supplementsEat foods that have more calcium (leafy greens, oysters, sardines, canned salmon, shrimp, and broccoli)Drink orange juice that contains added calciumRead food labels. Lactose is also found in some non-milk products -- including some beers.Expectations (prognosis)Symptoms usually go away when milk products are removed from the diet.ComplicationsWeight loss and malnutrition are possible complications.Calling your health care providerCall your health care provider if:You or your child has symptoms of lactose intolerance and you need information on food substitutes.Your symptoms get worse or do not improve with treatment, or you develop new symptoms.PreventionThere is no known way to prevent lactose intolerance.If you have the condition, avoiding or restricting the amount of milk products in your diet can reduce or prevent symptoms.ReferencesInformation from your family doctor.

Is lactobacillus dairy free?

Lactose free products are NOT the same as dairy free products. If an acidophilus supplement is called lactose free it means it does not do not contain any milk sugar, but it may contain isolated, lactose-free milk protein - so it would NOT be dairy free. A dairy free probiotic means it does not contain either lactose (milk sugars) or milk proteins.


Can lactose intolerant people consume raw milk?

No, all milk has the same amount of lactose in it, whether pasteurized or unpasteurized. You will still get the same symptoms you get from drinking milk that is not raw. Also, there a microorganisms in unpasteurized milk which can be very serious or fatal. See the related links below for more information.


Can you get sick from almond milk?

Food allergies and food intolerances are they the samething?

No they are not same. There is a difference between a food allergy and a food intolerance. The main difference between food intolerance and food allergy is the reaction that occurs when the food is ingested. An allergic reaction is an immune response, while an intolerance reaction is a digestive-system response. The ALCAT test is helpful to uncover all of your hidden food related conditions.
