Lactose (Definition)

Found in milk. Lactose is a large sugar molecule that is made up of two smaller sugar molecules, 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 are then absorbed by the cells lining the small intestine. The enzyme that splits lactose into glucose ...Read more

No: you can have an intolerance with out having an allergy. An allergy can be occur when your body makes antibodies to the milk protein- and an intolerance doesnt necessarily have to be related to antibodies. The most common allergy is IgE mediated, with rash, swelling, hives. An intolerance may not cause those symptoms- they may cause diarrhea ...Read more

How do milk allergies differ from lactose intolerance?

How do milk allergies differ from lactose intolerance?

Antibodies: People with a milk allergy develop antibodies to proteins in milk; every time they are exposed to those proteins (whether it's a little or a lot), they have a reaction. People with lactose intolerance are missing an enzyme that allows them to break down lactose; without the enzyme, the sugar in milk passes through their digestive tract unchanged causing symptoms. A little milk is often tolerated. ...Read more

Is lactose intolerance heredity?

Is lactose intolerance heredity?

Lactose intolerance: Lactose intolerance is common--25% of caucasians, 80% of afro-americans, almost 100% asians. Lactose intolerance can be secondary to lactase enzyme deficiency, or due to a bigger problem of small bowel inflammation, infection, infiltrative disease, and/or maldigestion. Don't assume its lactose intolerance unless tested, or at least assessed response to lactase enzyme replacement (like lactaid). ...Read more

If i'm lactose intolerant, should I avoid casein protein shakes?

If i'm lactose intolerant, should I avoid casein protein shakes?

Maybe...: There's more to milk than just lactose. Intolerance to milk may include problems with milk proteins or even with processing the fat component of milk. If your problem resolves with concomittant use of lactase enzyme when eating the same milk products (that cause gas & diarrhea in the absence of lactase) then lactose intolerance is likely. More elegant lactose intolerance testing is available too. ...Read more

Is casein strictly off limits if lactose intolerant?

No: Lactose is milk sugar. Lactose intolerance is when someone does not have enough lactase enzyme, the enzyme specific to digesting lactase. Lactose intolerance is very common. Caseine is milk protein. Lactase enzyme is not involved in digesting milk protein. Someone who is lactose intolerant can usually tolerate caseine if its in a lactose free food or if they take lactase (brand lactaid). ...Read more

How to check for lactose intolerance and gluten allergy?

How to check for lactose intolerance and gluten allergy?

Depends: Lactose intolerance is mostly a clinical diagnosis--usually leads to GI symptoms after eating foods containing lactose (dairy). Biopsy of the intestine can confirm the diagnosis as well. Celiac disease (gluten sensitivity) can be screened for with blood tests, and the confirmatory test is also a biopsy of the intestine. It's important that these tests be done while you're on a regular diet. ...Read more

Enzyme deficiency : Lactose intolerance is when the body cannot easily digest lactose, which is a sugar found in milk and dairy products.Lactose intolerance occurs when the small intestine does not make enough of an enzyme called lactase. Your body needs lactase to digest lactose. Milk protein intolerance is an allergy. ...Read more

What causes dairy intolerance?

What causes dairy intolerance?

Can't digest lactose: Milk has lactose as it's sugar. Milk is a complete food for baby mammals, so it has fat, protein, sugar, etc... Most people don't have as much "lactase" enzyme as they get older, but some people start losing their enzyme in childhood. Certain racial groups don't lose it. Without the enzyme, the lactose sugar is digested by the intestinal bacteria, so leads to gassiness, cramps, and some diarrhea. ...Read more
