Immune-Boosting Foods May Add to Flu Defense.

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.

 

Immune-boosting foods can improve your ability to ward off the flu and other health problems, according to the Academy of Nutrition and Dietetics.

 

Even a small nutritional deficiency can affect the body’s ability to stay healthy, said Heather Mangieri, a registered dietitian and academy spokesperson.
