5. Balance the gut
Some studies show that the first line of defense for illnesses like the flu actually begin in the gut. Your microbiome, or the collection of good bacteria that reside in your gut, can block virus replication in various locations within the body, including the respiratory system (5).
Support your gut flora diversity by eating prebiotic foods like fiber-rich vegetables, and by upping intake of fermented foods such as kefir and kimchi. If you end up taking an antibiotic, always be sure to replenish your beneficial flora afterwards with a probiotic.
A high-quality probiotic during this season is also a great idea to boost the health and diversity of good gut flora.
6. Eat seasonal foods
Fruits and vegetables that are actually in season during the colder months will be more nutrient-dense than their out-of-season counterparts. Embrace all that “winter superfoods” have to offer by eating produce that’s in season, like:
- Apples
- Beets
- Brussels Sprouts
- Cabbage
- Carrots
- Celery
- Citrus fruits
- Collard greens and chard
- Kale
- Leeks
- Onions
- Parsnips & turnips
- Pears
- Pomegranate
- Pumpkin
- Sweet Potatoes & yams
- Winter Squash
Beets and Brussels sprouts are high in vitamins A, C, and K, and a good source of fiber. Winter squashes and pumpkin are good sources of vitamins A and C, and B vitamins, high in antioxidants, and provide crucial minerals such as potassium, and magnesium.
For an easy way to pack some of these superfoods into your diet, try a smoothie with beetroot, carrot, apple, ginger, orange, and turmeric. You can also make delicious soups using pumpkins or squash.
If you need a little extra help staying on track this season, find out if nutrition counseling is right for you.
7. Flu-fighting botanicals
Many plants contain phytonutrients (plant nutrients) that stimulate and support the immune system. You’ve probably heard of elderberry or echinacea, but there are dozens of others. Astragalus root, which has been shown to support respiratory health, is a staple in Eastern medicine (7). These traditional herbs have been used for centuries to help fight off germs and support immune health. Astragalus root extract has also been shown to decrease the frequency and severity of upper respiratory infections in children and older adults (8).

8. The sunshine vitamin
Vitamin D levels often drop during the winter as most people spend less time outdoors. Low vitamin D can not only harm immune function, but also negatively affect mood and mental health. It’s important to keep your vitamin D (aka the sunshine vitamin) levels within a healthy range during the winter. Countless studies have linked low vitamin D levels to autoimmunity and other chronic diseases, making it an essential support for overall wellness.
If you live in the northern portion of the U.S., or suspect you may have low vitamin D, consider speaking with your doctor about testing vitamin D levels to properly guide supplementation.
9. Stay ahead of SAD season
Many of us have a case of the winter blues once the days get shorter, colder, and darker, but it’s important to be aware of your body adjusting to changes in sunlight during the winter months, versus the type of clinical depression that occurs with the changing seasons.
SAD, or seasonal affective disorder, is characterized by fatigue, moodiness, loss of interest, difficulty sleeping or excessive sleeping, weight gain, feelings of hopelessness or despair, and thoughts of suicide. SAD is real depression triggered by the changes in season. You can be proactive by reaching out to your integrative provider to do things like evaluate vitamin D levels, increase antioxidants, and discuss coping strategies.
Vitamin D supplementation in the winter is a must if you live in an area with really short days. Light therapy can also be beneficial. And finally, proper diet, exercise, hydration, and sleep are always important and will help your body adapt to the changes in sunlight.
Winter Wellness with Functional Medicine
No one likes getting sick, least of all during the winter months. Fortunately, there are things you can do to lessen your chances of succumbing to cold and flu viruses or other illnesses. Taking supplements, eating certain foods, and practicing self-care are all great ways to keep your body healthy during the winter. Additionally, functional tests can help identify risk factors that may make you more susceptible to illness. So don’t wait until you’re already feeling under the weather to take steps to improve your winter wellness routine. Go ahead and stock up on vitamin D, get a massage, and eat those oranges—your body will thank you later.
