Foods that Fight Flu Season

It’s the time of year that many of us dread…flu season. You try to take every precaution you can by washing your hands, sanitizing grocery carts and not touching your face—but sometimes even that isn’t enough to prevent the nasty flu bug! In the past, I would get sick at least once every fall/winter and would always have 1-2 sinus infections on top of that. That was until I changed my diet up a few years ago, and I have enjoyed the last few years sick-free!

Remember, no one single food will make you healthier and improve your immunity. But I do suggest that it may be more beneficial to get your vitamins from your fruits and veggies rather than a packet of Emergen-C.

Get your vitamins from your fruits and veggies rather than a packet of Emergen-C.

Antioxidant-Rich Fruits and Veggies

Ideally, your goal is to consume a wide variety of colors when choosing your fruits and veggies. Each color introduces a powerful antioxidant or plant nutrient into your system. For example, red-orange colored produce such as sweet potatoes, squash and carrots are great sources of Vitamin A and beta-carotene while blue, purple and dark red fruits like blueberries, raspberries and cherries deliver phytochemicals such as flavonoids that help reduce inflammation. Vitamin C can be found in red bell peppers, oranges, broccoli, kiwi and strawberries.

Eggs, Nuts and Seeds

These quick bites are good sources of zinc, which helps your T-cells and other immune cells function properly. Swap your afternoon wheat thins or granola bar for a handful of mixed nuts and seeds or even a hardboiled egg or two. In addition to the improved nutrient intake, you’ll also satisfy your hunger better and have more controlled blood sugars by choosing these good protein sources.

Proteins. Eggs, fish, chicken, lean or organic beef

Some studies suggest that inadequate protein intake can weaken the immune system by showing a decrease in the number of T-cells and antibodies being produced. A good goal to work towards is having protein with all your meals and with most of your snack choices.

Fatty fish and avocados

There are two great examples of healthy fats in the diet (omega-3 and omega-9s). Essential fats (fats that the body cannot produce) help decrease inflammation in the body as well as improve the integrity of our cell walls. I’ll explain in the next paragraph why this integrity is so important to immunity!

Immunity begins in the gut.

You gastrointestinal tract is your internal layer of skin. It can protect you from harmful agents invading your circulatory system; however, if its cell wall is compromised, you may be at a greater risk of getting sick this flu season. (This could be related to “leaky gut syndrome or intestinal permeability” however, not all practitioners believe in this concept). I know what you’re thinking—so what are the foods that damage my gut’s lining? Some of the main culprits could be foods high in sugar and simple carbohydrates such as candy, juice, soda, cereal, chips, crackers, pretzels, pasta and white bread. Three years ago, I pretty much cut out all of these foods from my diet. Could it be coincidental that I didn’t get sick the same time I cut out processed sugars and starches? Yes. However, I will remind you that I work in health care and am exposed to a lot of sick people on a daily basis during the flu season. In addition to not getting sick the past couple winters, I also noticed that I was less bloated, slept better and had more energy after changing my diet. While my results may differ from others following the same meal plan, it is certainly something to consider if you find yourself chronically getting sick all fall and winter long.

Remember—your immune system is exactly that—a system, not one single entity. To function well, it requires overall balance and harmony between all your health habits: diet, exercise, stress management and sleep.
