How to Boost Your Athlete's Immunity During Flu Season

fruits and vegetables

Cold and flu season is here, and it can be a struggle to keep your young athlete healthy as their friends and classmates start getting sick. As all sports parents know, a good defense requires a good offense, so here are a few simple nutritional tips to help boost your child’s immunity this season and hopefully keep them in school and in sport.

Add More Colors

Fruits and vegetables can be powerful medicine. TrueSport Expert Kristen Ziesmer, a registered dietitian and board-certified specialist in sports dietetics, recommends eating at least five servings of fruits and vegetables daily from all the colors of the rainbow – preferably, two fruits and three vegetables.

This helps ensure that your child is getting the vitamins they need to stay healthy: vitamins A, C, and E are all critical to a high-functioning immune system.

Add Zinc-Containing Foods

Researchers have found that zinc can boost immune function in children, yet globally, one in six people are deficient in the mineral. Foods high in zinc include red meat, shellfish, chickpeas, lentils, hemp seeds, cashews, and dairy. If you have a picky eater, try these delicious options:

  • Granola or oatmeal with low-fat milk

  • DIY trail mix: cheerios, raisins, peanuts

  • Peanut butter on whole-grain bread

  • Turkey, ham, or roast beef sandwich on whole grain bread

  • Hamburger on a whole grain bun

Limit Processed Foods

The Cleveland Clinic also recommends limiting processed foods for your young athlete, as the gut bacteria that thrive on highly-processed sugars aren’t as immune-system-boosting as the bacteria that thrive on a healthier, high-fiber diet.

Encourage your athlete to consume more whole foods, including brightly colored fruits and veggies, as well as zinc-rich foods.

Add Pre and Probiotic-Rich Foods

Probiotics – live, helpful bacteria that are naturally found in your body, can also help boost a child’s immunity during cold and flu season. A recent study on allergy prevention and treatment shows a decrease in upper respiratory infections in people using probiotics, and they can guard against viral infections. Rather than popping a pill, introduce fermented foods like sauerkraut, kefir, yogurt, kombucha, and kimchi. If you have a picky eater, consult your family physician to get a recommendation on whether a probiotic is right for your child.

Ziesmer adds, “Prebiotics provide probiotics with food. These include foods like bananas, garlic, onions, whole wheat bread, and asparagus.”

Bonus Tip: Remind Them to Wash Their Hands

Proper hand-washing is the number one recommendation when it comes to preventing the flu from spreading, so even with a boosted immune system, it’s still important to help your athlete get in the habit of washing their hands frequently and effectively by rubbing soapy hands with warm water for at least 20 seconds.

While you can never completely safeguard against your child getting sick during the cold and flu months, with a few simple preventative measures – that are all healthy habits anyway – you can help boost their immune system.
