The Secret Weapon Against Getting Sick? Good Nutrition
A new spin on an old saying is “starve a cold, feed the gut” — an approach that may help keep sickness at bay. Nutrition is important, and foods you may already have on hand can offer your immune system a healthy kick.
Emily Clairmont, clinical dietitian in Culinary Medicine at The University of Vermont Medical Center, reminds us that “food is medicine” and that research indicates “as much as 70% of immunity is in the gut.” It’s important to fuel your immune system with supportive nutrients because it is your body's natural defense system that helps fight infections by attacking germs that cause disease, she explains. Your immune system is also essential for triggering a healing response within damaged tissues and cells.
Clairmont shares how to improve your gastrointestinal health to boost immunity and stay ahead of cold, flu and other illnesses:
- Eat a balanced diet with a variety of fresh fruits, vegetables and whole grains.
- Snack on antioxidant-rich, brightly colored fruits and veggies (think oranges, berries, peppers).
- Pop a few pumpkin seeds for extra zinc.
- Enjoy gut-friendly probiotics like yogurt.
- Consider taking a multivitamin .
“Vitamins, minerals and phytonutrients – found in plant-based foods – are supportive of the immune system,” Clairmont explains.
In fact, vegetables, including the starchy root variety, provide an abundance of nutrients your body uses to produce energy, repair tissues and support the immune system. Vegetables’ dietary fiber is food for the trillions of healthy bacteria living in your digestive tract. Whether you’re aware of it or not, these bacteria are essential and help you digest and absorb essential nutrients.
The colors, flavors and aromas you experience with vegetables and all plant foods are nutrients, too. Thousands of these compounds, known as phytonutrients, have important roles in helping your immune system be as strong as it can be.

Rainbow Root Vegetable Latkes
- 1 lb. assorted root vegetables (turnips, sweet potatoes, parsnips, carrots, rutabagas, beets)
- 1/2 lb. Yukon gold potatoes
- 1 bunch chives, thinly sliced
- 2 large eggs
- 1/3 cup rice flour
