Flu-fighting foods

Posted: Updated:
NEW YORK (MYFOXNY) -

As U.S. health officials recommend flu shots and frequent hand washing for protection during this season's influenza outbreak, dietitians point to another significant defense weapon: healthy foods, according to a HealthDay report.

The Academy of Nutrition and Dietetics said that immune-boosting foods can improve your ability to ward off the flu and other health problems.

However, it is important to remember that no food can be a foolproof shield for infection. A healthy immune system makes you better prepared for the flu season but it can't fight off every germ. 

Whether they're canned, frozen or fresh, adding more fruits and vegetables into your diet is a way to ensure you are getting the most nutrients and vitamins from your foods, the Academy of Nutrition and Dietetics advises. Selecting foods from all of the food groups will also help you to get protein, calcium and fiber in your diet.
