These foods aren't only delicious but then can also help kids ward off the flu.
When it comes to vitamin C, many people think of oranges. However, strawberries and kale are also bursting with the vitamin and can be a good addition to health-boosting meals.
For tasty treats, kids can enjoy these recipes from nutritionist Joy Bauer.
For a yummy smoothie, combine one banana with some strawberries, kale, blueberries and milk. Blend it up and serve.
"The best part, your kids are gonna love making the smoothie and then slurping it down," Bauer said.
And broccoli is another good cold-buster.
"Broccoli is loaded with vitamin C to boost your immune system," Bauer said.
But getting kids to eat broccoli can be a challenge, so Bauer recommends steaming it and hiding it in a guacamole dip.
She said parents can also do the same with pizza.
"I am sneaking in some eggplant. Eggplant is loaded with antioxidants that can help build up their immune system," Bauer said.
All of these healthy recipes can be found in Bauer's new children's book, "Yummy Yoga." She said combining yoga with a nutritious diet is the key to fending off sickness.
