Cold and Flu No More! Your Immune Support Guide

Cold and flu season is upon us. While you don’t have full control over the germs your kid brings home from school or the stranger who sneezes beside you on the subway, you do have control over how you prepare your body and immune system this season.

A robust immune system is essential for optimal vitality, dodging the dreaded flu, and avoiding other pathogens lurking around. For this reason, we created a quick 3-tier immune support guide you can use over the next few months to give yourself the best shot at keeping germs at bay. 

Tier 1: Essential Immune Defense 

A diet high in all of your micronutrients is essential. The key nutrients that have a powerful effect on the immune system and fighting infection are listed below. Challenge yourself to include a few of these foods into your meals and snacks each day. 

  • Vitamin A
    • Sources: Carrots, sweet potatoes, pumpkin, cantaloupe, and squash
  • Vitamin C
    • Sources: Citrus fruit and leafy greens
  • Vitamin D
    • Sources: Fatty fish and fortified foods such as cereals, orange juice, and milk
  • Vitamin E 
    • Sources: Broccoli, spinach, almonds, peanuts, hazelnuts, and sunflower seeds
  • Copper
    • Sources: Shellfish, whole grains, beans, nuts, and potatoes
  • Selenium

Tier 2: Specialty Immune Defense 

Choosing healthful foods is the first priority as they provide a wide range of nutrients and numerous benefits aside from just immune support. Additionally, there are specific compounds and supplements that can be a second line of immune defense. 

Elderberry can help your body prepare for cold and flu season

Reduces the length and severity of cold symptoms and supports immune health

Turmeric can help your body prepare for cold and flu season

Ways to incorporate: Supplement or enjoy black and green teas

Tier 3: Added Support

Taking care of your body is not just about what you put in your mouth. Your immune system is best supported when your body as a whole is best supported. This means managing your stress and prioritizing your sleep, among others. 

A flu shot can help your body prepare for cold and flu season

Flu shot 

The flu vaccination can help reduce the likelihood of getting the flu or reduce the time spent having the flu. 

A hot shower can help your body prepare for cold and flu season

Hot shower

Hot showers and steam can help reduce chest congestion and can clear stuffy nasal passages.

Getting outdoors can help your body prepare for cold and flu season

Get outdoors 

There are so many benefits of simply going on a walk —even during colder weather. Increased stress can decrease immune response so it’s a good opportunity to clear your mind. Absorb some vitamin D from the sun while getting your exercise in. Lastly, the more cooped up you are, the higher the chance you’ll catch that cold going around.

Adequate sleep can help your body prepare for cold and flu season

Adequate sleep

Aim for 7-9 hours of sleep per night as inadequate sleep impairs your immune response.  

Bonus: The Ultimate Immune Defense Day

Now, put all of your efforts together to holistically support your body and kick cold and flu season to the curb! Here’s an example of what that could look like. 

  1. Start your day by taking an elderberry supplement with a tall glass of water.
  2. Whip up a 10-Minute Turmeric Golden Milk Recipe to enjoy while you’re getting ready for the day. 
  3. For breakfast, make some Caramelized Banana & Toasted Sunflower Seed Toast with a glass of fortified orange juice. This meal is high in copper, vitamin E, zinc, and vitamin D.
  4. For lunch, cozy up with a Warm Roasted Butternut Squash Salad packed with vitamins A and C.
  5. After lunch, bundle up and go on a long walk through a local trail to get some exercise, vitamin D, and fresh air.
  6. Make a simple dinner tonight. Sheet Pan Dinner: Maple-Glazed Salmon with Sweet Potatoes is loaded with selenium, vitamin E, vitamin D, and vitamin A. 
  7. Wind down with a long, hot shower.
  8. End your evening with a cup of decaffeinated green tea for your daily dose of L-theanine.
  9. Last but not least, head to bed early for a full 7-9 hours of sleep.
