Broccoli's peak season is October through April, so stocking up during the winter months might be a good idea. This versatile veggie can be prepared in a number of different ways--all of which should give you access to the flu- and cold-fighting nutrients found within them.
Specifically, broccoli is a good choice because of its vitamin C content and its high fiber content. Vitamin C can help keep your immune system in order, while broccoli's fiber (and bland taste) will help you maintain a healthy diet during a time when your appetite probably isn't at its highest or most adventurous.
While Thanksgiving-style sweet potatoes probably aren't the healthiest option, less processed sweet potatoes (minus the marshmallows) can be a smart option during the chilly months.
Sweet potatoes are known to be high in vitamin A, which we normally associate with healthy skin. However, vitamin A is also important for the mucus membranes in your sinuses--and those need all the help they can get during a cold!
Whether you're steeping it in tea or adding it to a dish for some more flavor, ginger is a delicious and healthy root vegetable. While it's grown year-round, ginger typically takes a starring role around the winter holidays.
Ginger is especially good at dealing with one pesky symptom that shows up with both colds and the flu--a sore throat. Its anti-inflammatory properties help to soothe the discomfort and might even shorten your recovery time.
Kale might have a reputation for being an obnoxious, "trendy" food, but if you can stand the unique, earthy flavor it might be a good addition to your pantry during the winter months. It's a cold-weather vegetable, so don't miss it while it's at its peak in the winter!
Kale has a mile-long list of important nutrients, but when it comes to fighting the cold and flu, its vitamin C and magnesium content are the clear winners. Both play a key role in immune system health, and magnesium even has anti-inflammatory properties.
Beet season is usually over by the fall, but this colorful vegetable fares well in storage through the winter months. And if you're worried about the cold and flu, it's definitely something you want on hand.
Beets contain some of the most important nutrients for fighting these nasty illnesses. You've got vitamins C and B6 (for immune system health), vitamin A (for sinus health), and magnesium (for its anti-inflammatory properties).
Brussels sprouts are not the most exciting or tasty vegetables, but if you can stomach them, they're great for dealing with a cold or the flu. And with a season that runs from September to February, the winter months are a great time to try them out.
Brussels sprouts contain a wide variety of antioxidants which can help with all sorts of related problems, from managing symptoms to reducing your recovery time.
Butternut squash is a fall and winter favorite. But in addition to being a big, colorful vegetable, they might be able to help your cold and flu symptoms, too.
Butternut squash are full of important nutrients, but they don't have a distinct, overbearing taste--which means that you can still eat healthy even when your appetite isn't there. Additionally, they're a good source of vitamin A, which can help with sinus issues.
Despite its exotic, tropical appearance, pomegranates are actually a cold-weather fruit--its season runs from September to December. So be sure to snag them while you have a chance!
Like many fruits, pomegranates are high in vitamin C, which can help boost your overall immune system health. But they're also high in various antioxidants which can help reduce inflammation associated with illnesses.
Even the humble potato can help with cold and flu troubles! And a warm potato dish sounds like the perfect thing for a cold winter night.

Pumpkin season doesn't stop when Halloween is over! This is another member of the squash family you'll want in your diet all winter long.
Its biggest claim to fame for fighting the cold and flu is its vitamin A. As we've already seen, this nutrient is essential if you don't want your sinuses congested and inflammed all season long.
Because blueberries are grown globally, you can still enjoy them in the winter, even though they're technically a summer fruit. And of everything on this list, they're probably the most important superfood.
Blueberries are known to possess more antioxidants than any other fruit or vegetable, and when you couple this with their high vitamin C content, it's hard to beat this fruit in terms of immune system health.
Green tea is a pretty standard go-to for those who are sick, and for good reason too! This drink won't only warm you up in the winter--it will help you fight the flu as well.
Green tea is high in catechins, which are a particularly powerful type of antioxidant. Specifically, catechins have shown promise in both treating and preventing the flu.
What winter stew would be complete without carrots? While they're technically a spring and fall crop, they store easily during the winter months.
Carrots contain high levels of beta-carotene, which is important for multiple reasons. For one, our bodies can convert it to vitamin A, which can help with sinus congestion unpleasantness. However, beta-carotene is also important for the creation of white blood cells, which help fight off illnesses like the cold and flu.
Navel oranges are a staple winter crop for states like Florida. Plus, they're pretty good at helping you deal with the cold and flu too!
To no one's surprise, oranges are full of vitamin C, and as we already know, that's a crucial nutrient for maintaining a healthy immune system. So go on and have a glass of orange juice for your health!

A slice of apple pie might not be good for your waistline, but it could help in preventing the cold and flu! Apple season typically ends in November, so be sure to snag them during the early winter months.
Like most fruits, apples are high in antioxidants which help keep your immune system strong and your body healthy.
Looks can be deceiving, especially when it comes to cauliflower. This vegetable hits its peak in November and is hiding an important secret when it comes to the cold and flu.
Besides citrus fruits, cauliflower is actually the best naturally occurring source of vitamin C. So be sure to stock up if you're looking for an immune system boost!
Depending on the variety, you can find mushrooms growing in any season--including the winter. And this fungus can be a tasty way to stay healthy when it's cold, too!
Mushrooms are a good source of vitamin D--which plays two different roles in the fight against colds and the flu. For one, it helps promote healthy white blood cells, which are essential for fighting off illnesses. Secondly, it has antimicrobial properties which can also help eliminate infections.
Salmon is a good source of protein, which is important whether you're sick or not. However, salmon might specifically help folks currently dealing with a cold even more.
