Medical Edge: Probiotics may be effective in preventing colds

(Continued)

For adults, the recommended amount of vitamin C is 65 to 90 milligrams a day, and the upper limit is 2,000 milligrams a day. For most people, a large orange, or one cup of sliced strawberries, chopped red pepper or broccoli provides enough vitamin C for the day.

If you take a vitamin C supplement, stick to one that provides about 100 percent of the amount you need in a day. Avoid “megadoses” that have, for example, 500 percent of the amount you need daily. When it comes to vitamin C, more is not always better. Too much may cause diarrhea, nausea, abdominal bloating and cramping, heartburn and headaches.

Of course, there are plenty of other steps you can take to help keep from catching a cold that don’t involve taking anything. Wash your hands regularly, keep kitchen and bathroom surfaces clean, and don’t share drinking glasses or utensils with others. Using alcohol hand sanitizers is an excellent way to keep hands clean while on the move.

If you do get a cold, you can help prevent it from spreading to those around you by coughing or sneezing into a tissue or the bend of your elbow, rather than your hands. The old recommendations to drink lots of fluids and get plenty of rest won’t cure your cold, but they can help you feel better. Having a bowl of chicken soup is a good idea, too. — Abinash Virk, M.D., Infectious Diseases, Mayo Clinic, Rochester, Minn.
