5 Things You Need in Your Kitchen for Cold + Flu Season

When cold and flu season rolls around, what’s on your grocery list?

As a holistic nutritionist, I pay attention to how I’m nourishing my body throughout the season. Your immune system needs consistent nutrition to do its job and everyday foods can help supply it.

These are five things I keep stocked in my kitchen (and simple ways you can use them in yours).

1. Fresh ginger

Fresh ginger brings more than heat and flavor. It contains gingerols which have shown antioxidant, antibacterial, anti-inflammatory activity in research. 

I keep ginger around because it’s easy to use regularly. Grate it into a stir-fry, blend a little into a dressing or my favorite - add it to fresh juice. Ginger, lemon and hot water also make a simple tea for those cooler mornings (check out my other tea blends here). 

Kitchen tip: Freeze small portions of ginger so you always have some ready to grate.

2. Fresh garlic

Garlic is one ingredient I’m generous with in the kitchen.

It contains prebiotic fibers that feed beneficial gut bacteria. Those bacteria are part of the relationship between your digestive system and your immune defenses. This is why gut health deserves attention during cold and flu season, too.

Crushing or chopping garlic also produces allicin, a substance studied for its antimicrobial activity in laboratory research.

Kitchen Tip:

Crush or chop your garlic and let it sit for about 10 minutes before cooking. This gives the enzyme that produces allicin time to work before heat slows it down.

3. Lemons

Lemons are an easy way to work some vitamin C into your day.

Vitamin C supports normal immune function and helps protect cells from oxidative damage. Your body also uses it to make collagen which helps maintain tissues such as your skin — one of your body’s protective barriers.

A squeeze of lemon can brighten a meal while adding nutrients. I use it in water, teas, dressings and over cooked greens to help with iron absorbption.

Try it: Mix lemon juice with olive oil, minced garlic and your favorite herbs for a quick dressing.

4. Fermented foods like kimchi, miso and sauerkraut

Your cold-season grocery list deserves a fermented food.

In a small Stanford study, adults who ate a diet rich in fermented foods increased the diversity of their gut microbes and reduced several markers of inflammation. That finding supports including fermented foods as part of a routine that cares for your gut.

Kimchi, miso and sauerkraut are two options I like. Look for varieties with live cultures, and check kimchi ingredients if you eat plant-based because some contain fish sauce or shrimp. Want to make your own? Try my homemade sauerkraut recipe — a simple way to keep fermented food in your fridge.

Try it: Add a small serving to a grain bowl, sandwich or plate of roasted vegetables.

5. Red bell peppers

Oranges get plenty of attention for vitamin C but red bell peppers deserve a spot on your list.

Just ½ cup of raw red bell pepper provides about 95 milligrams of vitamin C, compared with approximately 70 milligrams in a medium orange. That makes peppers an easy food source of a nutrient your immune system needs.

Try it: Slice them for dipping in hummus, chop them into a salad or tuck them into a wrap.

Start with your next grocery trip

You don’t have to overhaul your entire kitchen. Pick a few ingredients you enjoy and find ways to use them consistently.

Alongside enough sleep, regular meals and movement, nourishing food belongs in your seasonal routine.

Save this list and take it with you on your next grocery run. 💚
