How to Fend Off the Flu

And what to do if you do get sick
WebMD Weight Loss Clinic - Expert Column

With flu season upon us, we all need to be vigilant about taking good care of ourselves to boost our immunity and avoid getting sick. An ounce of prevention could be worth a week's time in the sickbed!

So what should you be doing to stay flu-free? All are things you should be doing anyway for the good of your health:

  • Taking a daily multivitamin
  • Getting enough rest and regular physical activity
  • Drinking plenty of liquids
  • Following a healthy eating plan that includes a variety of vitamin- and mineral-rich foods

In particular, vitamins B6 and B12 contribute to a healthy immune system. Vitamin B6 is widely available in foods, including potatoes, spinach, turkey, beans, and enriched cereal grains. B12, on the other hand, is only available from animal sources such as meat, milk, and fish.

Minerals such as selenium and zinc also work to keep the immune system strong. These minerals are found in protein-rich foods such as beans, nuts, meat, and poultry.

Keeping up with your physical activity program can help, too. The American Council on Exercise (ACE) recommends regular, moderate exercise to boost the immune system. According to ACE, people who exercise four to five times per week are less likely to come down with colds and flu.

And don't forget to take simple "respiratory hygiene" precautions that can help reduce the spread of disease, including:

  • Washing your hands frequently, using soap, for at least 15 seconds
  • Avoiding close contact with people who are sick
  • Cleaning the headsets of your telephones, and washing doorknobs, railings, and other frequently handled objects to keep them free of germs
  • Keeping your hands away from your eyes, nose, and mouth
  • Covering your mouth and nose when you cough or sneeze

What to Do When You've Got the Flu

If you do catch the flu, see your doctor, and ask about antiviral medications that can reduce your sick time by a day or two and make you less contagious. While you stay home and try to recover, follow this advice from the Centers for Disease Control:

  • Drink plenty of fluids
  • Rest
  • Avoid tobacco and alcohol
