Absorbing Nutrients and Medication

Choosing,
preparing and eating the right food is very important when
fighting HIV or any other disease. Taking your vitamins,
minerals and medications is also very important. But before
these nutrients and chemicals can do you any good, your body
must absorb them into your bloodstream. If you don't absorb
them, they will leave your body the next time you move your
bowels. The big question is what can you do to increase your
body's absorption of nutrients and medication? The way you
take medication, what you take it with, the way you cook,
what you eat and how you eat it all play a role in
increasing -- or decreasing -- absorption. You must also
have a stomach and an intestinal tract that is working well
enough to absorb these nutrients.
To start, don't take any
medication with wine, beer, liquor, mixed drinks or any other beverage
containing alcohol. If your cough medicine has alcohol in it, don't use it to
wash down your aspirin. This combination can irritate your stomach and my cause
it to bleed. Bleeding stomachs don't help digestion. Don't take your evening
vitamins with a glass of wine. Better still, don't drink any alcohol. HIV loves
alcohol and flourishes in alcohol preparations in the lab. Generally, you should
not take medications with acidic beverages, especially grapefruit juice. Take
your medications and vitamin/mineral supplements with an eight-ounce glass of
pure water. However, grapefruit juice increases the absorption of saquinavir.
(You can drink a glass of grapefruit up to two hours after taking saquinavir.)
If you are in doubt, ask your pharmacist.
Pharmacists now have at least 50
different information strips with various instructions that they can attach to
prescription bottles. On a recently filled prescription for antibiotics, there
were four information strips about how best to use the medication. Two were
related to eating. The first instruction was to take the medication on an empty
stomach, either one hour before or at least two hours after eating. The second
direction was not to take dairy products, antacids or iron preparations within
one hour of taking this medication. In other words, don't drink a glass of milk
with antibiotics like Tetracycline. The absorption of both the calcium in the
milk and the medication may be reduced.
Two other examples among hundreds
of possible drug/drug and drug/nutrient interactions should be mentioned.
Maintaining your appetite is a challenge when you are ill. In addition, many
people lose their appetites completely when they become depressed. Therefore,
try not to take an antidepressant that can further decrease your appetite and as
a result increase your weight loss. There are antidepressants on the market that
can stimulate your appetite, help you eat more and help you gain weight. Ask
your doctor about their possible use. Many people of European and African
descent are lactose intolerant as adults. For them, drinking milk and using
various dairy products can cause bloating, stomach discomfort, and very often
diarrhea that can lead to weight loss. People who are lactose intolerant avoid
milk and milk products, use an enzyme product called Lactaid or pay a high price
for their indulgence. This isn't news. What many people don't know is that
lactose may be an ingredient in their medication. The amount of medicine in any
pill makes a very small percentage of the pill itself. The rest of the pill is
made up of a filler called the excipient, which may be lactose. One of the new
protease inhibitors that uses lactose as a filler is saquinavir (Invirase). The
most common side effects of saquinavir are nausea, stomach discomfort and
diarrhea. There may not be enough lactose in one saquinavir tablet to cause any
trouble, but if other medications also contain lactose as the filler and someone
is taking ten or twenty or thirty different tablets per day, it is conceivable
that this could be a serious problem. It is certainly worth discussing with your
doctor or pharmacist.
Cooking foods in various ways
affects the nutrient content and how easily they can be absorbed. Different
problems exist for animal and plant foods, but there are some basic guidelines
that affect both. Cooking with moist heat is usually better than dry heat or
frying for ease of absorption. Chicken cooked in a covered pot with rice and
vegetable or in a soup is easier to digest than chicken cooked on a barbecue or
roasted. Cooking methods are especially important since the chicken and other
meats and fish must be thoroughly cooked in order to kill all the dangerous
bacteria that may be in them. The problem with roasting and barbecuing is that
potentially carcinogenic compounds are produced whenever foods are charred.
Cooking to well done when roasting or barbecuing usually produces a charred
outer surface. Foods also become hard, difficult to chew and more difficult to
break down in your stomach. Chewing is very important for several reasons. It
increases your satisfaction while eating, it helps your body to release various
digestive enzymes, it strengthens your teeth and gums. It also increases the
surface area of the food going into your stomach so that the digestive juices
there can do a better job of taking the food apart to make it easier to absorb.
Moist cooking usually produces a well-done food that is softer and easier to
chew, won't be charred at all and will be more easily digested.
Since we all like variety and
don't cook and eat simply for the nutrient content of the meal, there are some
tricks you can use when you are barbecuing to get more digestible food. Precook
meat in a microwave or par boil it before barbecuing or roasting. This step will
shorten the cooking time on the barbecue or roasting rack. Wrap hamburgers in
aluminum foil so that they cook in their own juices on the grill.
I don't suggest trying to scrape
off charred parts or removing skin from chicken, since that level of
self-control eludes most of us, especially if we are at a party. Try it, you may
succeed.
The problems with cooking
vegetables so that they retain their "goodness" and palatability are different
than the problems we have with cooking meats. Many vegetables if cooked too long
can lose 50 percent or more of their vitamins and minerals and become mushy.
This long cooking time may make vegetables easier to digest, but they are not
very appealing to eat this way. If your vegetables (and your fruits) are not
wrapped and refrigerated before use, the natural processes that go on in these
plants will destroy may of the nutrients even before they are cooked. The best
way to cook most vegetables is to use a small amount of water, in a covered pot
with a steamer that keeps the vegetables completely above the water. Steam the
vegetables until they are a bit softer than when they are raw. This process will
make them easier to digest and enable them to retain most of their nutrients.
Can you imagine a Valentine's Day
card with a stomach on it instead of a heart? Perhaps both? When I am with
people who annoy me, if I am working too hard or if I have unpleasant thoughts
my stomach, not my heart, is in a knot. My sense of taste changes. this doesn't
mean that I suddenly like red glen-plaid suits, with bell bottom pants and polka
dot ties, but that I don't feel like eating. Everything is "off." I may even get
diarrhea. The best remedy is to eat in a pleasant, relaxed setting, with people
you love, eating food that makes you feel good. Take pleasure in taking care of
yourself. You deserve it.
