When Gina Gallo, a school librarian in Lacombe, La., gets sick, she can take care of herself. She gets her own medicine, makes her own food, and "deals with it," as she puts it. But when her fiancé gets a cold, she says he has "a complete system breakdown."
"The world stops and the whining is incessant," she says. "I am expected to bring him food, take care of him, and generally treat him like the baby that he is."
Gallo's fiancé declined to talk with WebMD for this story. Their Mars-Venus situation...
Zinc is an essential mineral that's found in almost every cell, and it helps your body resist infection. It also plays an important part in tissue repair. And it may lower the ability of cold viruses to grow on or bind to the lining of your nose.
You can buy zinc as supplement, but it's also found naturally in a number of foods, like:
Researchers report mixed results. One analysis reviewed 15 earlier studies and found that taking zinc through the first few days of a cold, either as a syrup or lozenge, may shorten how long you're sick.
It also appeared to prevent colds in people who used it over the course of about 5 months.
But in other studies, researchers found no differences in symptoms between those who took zinc and those who took a "dummy" pill.
What does this research mean to you and your family? For now, the studies are inconclusive. For every one that shows a benefit with zinc, there's another that finds it doesn't help at all. Many experts say that if there is any advantage in taking zinc, it's minor.
Is It Safe?
Short-term use -- less than 5 days -- doesn't cause serious side effects, but it can make your mouth irritated, leave a metallic taste, or give you an upset stomach.
Experts recommend that you not take zinc for more than 5 days. Long-term use -- more than 6 weeks -- can lead to copper deficiency.
Researchers say zinc nasal sprays cause animals to lose their sense of smell. There have been several reports of people having decreased sense of smell or completely losing it. Because of this risk, the FDA issued a warning to stop using several nasal sprays that contain zinc.
Keep in mind that zinc is necessary for your health and safe to take through food such as seafood and eggs. But supplementing with higher doses, particularly for a long time, can be toxic.
