- Is There Medical Evidence to Support "Feed a Fever, Starve a Cold"?
-

- ------------------------------------------------------------------------------
-
- QUESTION: "Feed a fever, starve a cold." Is there any medical evidence to
- support this advice common in our medical remedies folklore?
-

-
- ANSWER: The saying would probably be more accurate as "feed a fever, feed a
- cold." That's because research shows that the body may actually lose
- nutrients during an infection.
- When you have an infection in your system, your body responds by changing
- your metabolism in a certain way--no matter what the cause of the infection.
- For instance, one study has shown that the level of antidiuretic
- hormone--which reduces the output of urine--increases during illness. For an
- illness accompanied by a fever, one day before the fever starts, the body
- excretes sodium in the urine. During the fever, the body retains salt and
- water.
- The way you handle proteins changes during an illness too. Some research
- has shown that the level of amino acids (building blocks of protein) in the
- blood rises during the incubation period of an illness, and drops once the
- illness sets in. Even the changes in concentrations of individual amino acids
- during an illness can be predicted: Phenylalanine increases or remains the
- same; tyrosine falls in relation to the change in phenylalanine; tryptophan
- increases; alanine falls.
- During an infection, the body also appears to waste nutrients--more are
- lost via excretion. And during a fever, your metabolism increases 13% for
- each degree centigrade of fever. Plus, blood levels of such metals as iron
- and zinc may decrease, the serum level of copper may increase, and serum
- cholesterol may fall during mild viral illnesses.
- What does all this mean to you? Basically, if you're ill, it's important
- to eat right. Good nutrition may help your body fight off the bug that is
- attacking you and causing your illness.
