Are you Lactose Intolerant?

If you suffer from nausea, cramps, bloating, gas, or diarrhea after
drinking milk or eating dairy products, you may be lactose intolerant.
This is a common reaction. According to some reports, between 30 and 50
million Americans are lactose intolerant.
Lactose is the sugar found in milk and other dairy products. The
small intestine produces an enzyme called lactase whose job it is to
break lactose down into two simple sugars called glucose and galactose.
The glucose is then absorbed into the bloodstream for nourishment. If
your body does not produce enough lactase, the unaltered lactose makes
its way into the large intestine and begins to ferment, producing acids
ALLERGY OR INTOLERANCE?
Some think that they are allergic to milk when they have these
symptoms. Usually this is not the case. Food allergies are rare.
According to some experts, only 1 to 2 percent of the general
population is affected by a true food allergy.
What is the difference?
Though the symptoms are similar, there are differences. With an
allergy, the immune system produces a "histamine" to fight against
foods you have ingested to which you are allergic. Some symptoms may be
swelling of the lips or tongue, hives (rash), or asthma. Lactose
intolerance will not cause these symptoms because the immune system is
not involved. Lactose intolerance is the body's inability to assimilate
a food properly, causing a reaction.
How can help you tell the difference?
If it is a real food allergy, the reaction will occur within
minutes of ingesting the food that you are sensitive to. If the
symptoms do not occur for an hour or more, it is most likely lactose
FOODS TO AVOID
These foods may also contain lactose and could cause symptoms:
Bread and bread products
Cakes and cookies
Some prescription drugs
Some over-the-counter medicines
Pre-mixed foods for pancakes, biscuits, and cookies
Processed breakfast cereals
At this time, there is no treatment that can cure the problem, but
you can prevent some of the symptoms by ingesting a food enzyme dietary
supplement just before taking your first bite of food. These contain
lactase to assist the intestines in converting lactose. Products come
in pill or liquid form. You can also take probiotics (opposite of
antibiotics)on a regular basis. These help produce "good bacteria" in
the body, promote good digestion and reduce the reaction your body may
have to foods containing lactose.
Through trial and error, you may be able to determine which foods
or what amount of foods cause you the most discomfort. By being
observant of your body's reaction, you will find that you know how much
you can or cannot digest.
You may have to cut out dairy products altogether. You should,
however, find other sources of calcium that has been supplied through
the dairy products. Certain green vegetables and some kinds of fish and
nuts are high in calcium.
Lactose intolerance is not life threatening, just uncomfortable and
sometimes embarrassing. Managing lactose intolerance can be
challenging, but possible. Be observant of what you eat and take
preventative measures once you determine what foods cause you the most
problems. Then you should find that you are symptom free and can enjoy
most of the foods you love, always in moderation of course. If your
symptoms persist, there may be something more serious that requires a
visit to your physician. Learn to read your body and know when you need
to make adjustments in your diet and nutrition.
